Deep learning is a branch of machine learning entirely dependent on artificial neural networks. As neural networks mimic the human brain, deep learning is also categorised as a mimic of the human brain. There is no need to program everything unambiguously when using deep learning, as it enables the systems to cluster data and accurately perform predictions to mimic the human brain.
Deep learning, in simple words, implies it is a subset of machine learning, a neural network consisting of three or more layers. These neural networks and deep learning try to mimic the human brain's behaviour, allowing it to learn from huge amounts of data. Although a neural network with a single layer can make rough predictions, other hidden layers can assist in optimising and enhancing accuracy.
Deep learning is a specific type of machine learning that attains outstanding flexibility and power by learning to exemplify the world as an encapsulated grouping of concepts. Every concept is defined considering ease of understanding. Moreover, more abstract representations are computed compared to less abstract ones.
Deep learning is a branch of machine learning that uses algorithms for data processing. It replicates the thinking process and also develops abstractions. It uses different layers of algorithms for data processing, understanding human speech, and identifying objects visually.
Beginners can comprehend deep learning as a process where information passes through each layer, and the output of the preceding layer behaves as the input for the succeeding layer. Clearing these concepts is vital if you aim to have deep learning from scratch. Now let’s understand what it is used for.
Deep learning powers several artificial intelligence applications and services capable of enhancing automation and physical and analytical tasks without human interference. It is essential to learn deep learning because this technology is responsible for powering everyday products and services (for example - voice-enabled TV remotes, digital assistants, and credit card fraud recognition) and developing technologies (like self-driving cars).
In most cases, real-life deep learning applications are so impeccably integrated into everyday products and services that we are hardly aware of the complex data processing occurring in the background.
The following section discusses deep learning usage in some prominent areas:
A decent deep learning example can be its application in financial services. Financial institutions frequently use predictive analytics to execute algorithmic trading of stocks, evaluate business menaces for loan approvals, identify fraud, and organise client investment and credit portfolios.
Deep learning in data science is highly prevalent these days, using AI as an effective tool for customer service management. Implementing AI techniques facilitates enhanced speech recognition in call routing and call-center management. Consequently, customers benefit from a seamless experience.
The deep learning ai can be the deep learning analysis of audio that lets systems evaluate the emotional tone of a customer. In this deep learning in ai example, if the customer responds poorly to an AI chatbot, that system can redirect the conversation to human operators.
Another great deep learning example in real life is its use in customer service. Plenty of organisations employ deep learning technology in their customer service conduits.
For example, chatbots employed in a wide range of services, applications, and customer service portals are the direct form of AI. Traditional chatbots utilise natural language and visual recognition. But, more sophisticated deep learning chatbot solutions try to determine if multiple responses to uncertain questions exist. Depending on the responses received, the deep learning chatbot attempts to answer these questions directly or pass the discussion to a human user.
Virtual assistants like Amazon Alexa, Google Assistant, or Apple's Siri further outspread the idea of a chatbot using speech recognition functionality. It develops a new method to engross users in a tailored way.
The usefulness of deep learning in healthcare is highly prevalent because it owns a great ability to improve healthcare facilities for patients. The healthcare industry had hugely benefited from deep learning potential right from when the images and records in the healthcare industry got digitised.
The image recognition applications can help radiologists and medical imaging specialists (in the form of deep learning in medical imaging) to study more images in less time. Moreover, deep learning requires limited data to learn from.
Deep learning algorithms can study and learn from transactional data to detect large perilous patterns indicating fraudulent or illegal doings. Speech recognition, computer vision and deep learning, and many other deep learning applications can enhance the efficiency of investigative analysis. This is possible by retrieving patterns and proof from images, video and sound recordings, and documents. As a result, law enforcement can effectively analyse huge amounts of data more accurately and rapidly.
Automotive researchers use deep learning to identify objects like traffic lights and stop signs automatically. Deep learning is also useful for detecting pedestrians, and thus, it aids in reducing accidents.
Deep learning can capture the images nearby in self-driven cars by processing a large amount of data. Subsequently, it determines what actions must be accomplished –turning left, turning right, or stopping. Accordingly, there will be a reduction in accidents every year.
Deep learning helps enhance the safety of workers working close to heavy machinery. It automatically detects when objects or people are within a risky distance from machines.
Deep learning can recognise objects from satellites that trace areas of interest and recognise safe or unsafe regions for troops.
The concept of image captioning deep learning is prevalent these days. After you upload the image, the algorithm accordingly generates a caption. For example, if you say brown-coloured hair, it displays brown-coloured hair with a caption at the bottom of the image.
Deep learning machines are trained in the grammar and writing style of a text piece. Subsequently, a deep learning model automatically creates an entirely new text that matches the original text's writing style, grammar, and spelling.
Deep learning for computer vision is greatly enhanced to equip computers with high accuracy for image classification and object detection, restoration, and image segmentation deep learning.
The majority of the deep learning methods use deep neural network architectures. This is why deep learning models are commonly regarded as ‘deep neural networks’.
The term ‘deep’ in a neural network in deep learning typically relates to the number of hidden layers encased in the neural network. Usually, there are 2-3 hidden layers in traditional neural networks, but the deep network can include as many as 150.
Essentially, deep learning models are trained by implementing huge sets of characterised data and neural network architectures. These architectures and data directly study features from the data without undergoing manual feature extraction.
Artificial neural networks or deep neural networks try to imitate the human brain using a blend of data weights, inputs, and biases. These components work collectively to precisely distinguish, categorise, and define objects within the data.
In deep neural networks, multiple layers of mutually dependent nodes exist. Each layer builds upon the preceding layer to optimise the categorisation or prediction. The corresponding progression of computations through the network is termed ‘forward propagation’.
Input and output layers existing in a deep neural network are known as visible layers. In the input layer, the deep learning model inputs the data for processing. On the other hand, in the output layer, the final prediction or deep learning classification takes place. The classification in deep learning leads to accurate prediction.
Another important process in deep learning is called backpropagation. It uses algorithms, for example, gradient descent, to compute prediction errors. Subsequently, the algorithm fine-tunes the biases and weights of the function by shifting backwards over the layers in an attempt to train the model. The forward propagation and backpropagation work collectively to let a neural network in deep learning make predictions and resolve errors accordingly. With the repetitive use, the deep learning algorithm becomes progressively more precise.
The description above exemplifies the easiest kind of deep neural network. But deep learning algorithms are quite complex, and various types of neural networks are employed to solve specific problems.
For example, Convolutional neural networks (CNNs) are extensively used in deep learning for computer vision and image classification applications. They can detect patterns and features in an image and enable tasks like deep learning in object detection and recognition. Recurrent neural networks (RNNs) are widely used in natural language and speech recognition applications. The reason is that RNNs control sequential or time-series data.
Deep learning is extensively used nowadays because companies in various industries emphasise using cutting-edge computational techniques to discover useful information concealed over enormous volumes of data. Although the artificial intelligence domain is now decades old, innovations in artificial neural networks empower the eruption of deep learning.
Currently, companies of all industries are targeting to present their big data deep learning sets as a training platform for developing sharper AI programs. These programs can extract valuable information and interrelate it with the world more naturally.
As per researchers, certain components lay the foundation for developing smart, self-learning machines and will begin rivalling humans in their insight. These components are cutting-edge neural networks, outstandingly powerful distributed GPU-based systems and the availability of huge volumes of training data.
Deep Learning algorithms are widely used in manufacturing industries because they transform complex, time-consuming, expensive manufacturing processes into easy-to-understand, quick, and cost-effective ones. Moreover, Deep learning instils problem-solving ability in manufacturers. This ability can surpass conventional machine vision applications. Deep Learning achieves this with excellent reliability and strength.
Deep learning software optimised for factory automation empowers companies in several industries to develop innovative inspection systems. These systems drive the boundaries of machine vision and outline the future of industrial automation. Furthermore, these cutting-edge inspection systems blend the reliability and efficiency of a computerised system with the flexibility of human visual inspection.
By going through these three key points, you can understand why Deep Learning is used and why it's so popular. These points justify how Deep Learning is superior to classical machine learning algorithms:
Few more points justifying why to use Deep Learning:
Deep learning is a subdivision of machine learning. It uses algorithms for data processing, mimics the thinking process, and creates abstractions. Moreover, it uses layers of algorithms for data processing, understanding human speech, and recognising objects visually. Exploring its great features benefits myriad industries, but it is significant to know the associated history that illustrates how it's gradually developed. The below section illustrates Deep Learning history:
The initial efforts in developing deep learning algorithms trace back to 1965. In that year, Valentin Grigorʹevich Lapa and Alexey Grigoryevich Ivakhnenko used models with polynomial activation functions and successively analysed these functions.
The 1970s-era marked a momentary impediment to the development of AI. During this time, restrictions were put on research in areas like artificial intelligence and deep learning due to a lack of funding. But, individuals continued the research without funding through those challenging years.
Kunihiko Fukushima was the first to use the convolutional neural network in deep learning, designing the deep learning neural networks with convolutional layers and multiple pooling. Moreover, in 1979, he developed an artificial neural network called Neocognitron. This network utilised a hierarchical and multi-layered design. This design facilitated the computer to learn to identify visual patterns. Furthermore, the networks simulated modern versions and were skilled with a reinforcement tactic of recurring activation in the multiple layers. These networks become more robust with time.
The 1970s further saw a significant growth of backpropagation. It utilises errors in training the deep learning models. The concept of backpropagation gained popularity when Seppo Linnainmaa completed his master’s thesis, incorporating a FORTRAN code for backpropagation. Even though being developed in the 1970s, this concept was not deployed to neural networks till 1985. In 1985, Hinton and Rumelhart Williams validated the backpropagation concept in a neural network. This validation lets backpropagation offer remarkable distribution representations.
Yann LeCun enlightened the foremost practical manifestation of backpropagation, in 1989, at Bell Labs. This was done using a deep convolutional neural network and backpropagation to read the transcribed digits. Moreover, this combination of a backpropagation system and convolutional neural network in deep learning was adopted to read the numerals of transcribed checks.
The 1985-90s era perceived another hiatus in artificial intelligence. Consequently, it impacted the research of deep learning neural networks. Subsequently, in 1995, Dana Cortes and Vladimir Vapnik built the support vector machine. This machine was able to map and identify similar data. Sepp Hochreiter and Juergen Schmidhuber developed LSTM (Long short-term memory) in 1997. It proved useful for recurrent neural networks.
The year 1999 marked the next remarkable advancement in deep learning advancement. This year, computers used the speed of GPU processing. The advancement in deep learning led to quicker processing which increased the computational speeds by 1000 times across ten years. In that era, neural networks started competing with support vector machines. Neural networks used the same data as a support vector machine and offered better results but with slow speed.
The Vanishing Gradient Problem was announced in 2000 when the upper layers could not learn the “features” (lessons) created in the lower layers due to the absence of a learning signal in these layers. It was not a major problem for every neural network. However, it is limited to gradient-based learning methods only. Moreover, this problem resulted in some activation functions that compressed their input and decreased the output range in a disordered way. Consequently, large areas of input were mapped to an enormously small range.
In 2001, META Group (presently called Gartner) presented a consolidated research report. This report demonstrated the opportunities and challenges of three-dimensional data growth. This report depicted the blitz of big data deep learning and demonstrated the increasing speed and volume of data with increasing the range of data types and sources.
In 2009, Fei-Fei Li (an AI professor at Stanford) launched ImageNet. It assembled a free database of 14+ million labelled images. All these images worked as the inputs to train the neural nets. By the year 2011, there was a significant increase in the speed of GPUs. This speed was adequate to train convolutional neural networks without requiring pre-training on each layer. So, by 2011, Deep learning showed noteworthy advantages in terms of speed and efficiency.
In 2012, Google Brain launched the results of an atypical independent project known as ‘The Cat Experiment’. This project discovered the challenges of unsupervised learning. On the other hand, Deep learning sets up supervised learning that implies the convolutional neural network is trained through labelled data similar to the images from ImageNet.
The Cat Experiment used a neural network across 1,000 computers where 10 million untagged images (without labels) were randomly taken from YouTube. These images were taken for feeding inputs into the training software. From 2012 onwards, unsupervised learning remains a major goal in Deep Learning.
The year 2018 and beyond depicted the evolution of artificial intelligence. This evolution will be based on Deep Learning. Note that Deep learning is still in its growth phase. It constantly needs innovative ideas to advance further.
The detailed deep learning classification includes Pre-Processing, Learning, and Convolutional Neural Networks. Let’s understand each of them:
To understand how pre-processing takes place in Deep Learning, we first need background information on Variance and Covariance.
a. Variance and covariance
A variable’s variance describes the number of values spread. The covariance indicates the amount of dependency between any two variables. If the covariance value is positive, then the values of the first variables increase when the values of the second variable increase, and vice versa. If the value of covariance is negative, then the values of the first variables decrease when the values of the second variable increase, and vice versa.
Here is the formula to calculate variance:
Here, n = length of the vector
= the mean of the vector
The formula to calculate the covariance between two variables X and Y:
Pre-processing implies all the transformation of raw data before it is fed to deep learning or machine learning algorithms. For example, training a deep convolutional neural network on raw images may result in bad classification performances. The Pre-processing component is also vital to speed up training, for example, using centring and scaling techniques.
b. Mean normalisation
The next important component of Pre-processing is Mean normalisation, which refers to removing the mean from every observation.
The formula to calculate Mean Normalisation:
Here, X’: normalised dataset
X: original dataset
: mean of X.
Mean normalisation centres the data around 0.
Standardisation puts all features on an identical scale. Every zero-centred dimension is divided by the corresponding standard deviation.
Here, X’: standardised dataset
X: original dataset
x̅: mean of X
σx: standard deviation of X.
Whitening (also called sphering) data means transforming the data to a covariance matrix, i.e. the identity matrix (1 in the diagonal and 0 for the remaining cells). It is called ‘Whitening’ because the values of the remaining cells are 0 in reference to the white noise.
Although whitening is slightly more complex than other pre-processing, all essential tools are available to perform it.
Whitening in Deep Learning involves the following steps:
The learning component is the most important one in Deep Learning. This component helps you create neurons in a computer. For that, we use an artificial structure known as an artificial neural network in which there are neurons and nodes. There are certain neurons for the input value and certain for the output value. In between, plenty of neurons in the hidden layer might be interrelated.
a. Deep Neural Network
It is a kind of neural network with some specific complexity level. Multiple hidden layers exist in between the input and output layers. These values can model and process non-linear relationships.
b. Deep Belief Network (DBN)
DBN is a multi-layer belief network belonging to a class of Deep Neural Networks.
Here are the steps to perform DBN for accurate learning in Deep Learning:
c. Recurrent Neural Network
Based on the idea of performing the same task for each sequence element, the learning of recurrent neural networks enables sequential and parallel computation. Its working is identical to the human brain; there is a huge feedback network of connected neurons. The connected neurons can store essential information about the input they obtained, making them more accurate.
In simple terms, a neural network is a sequence of algorithms that undertakes to recognise underlying relationships in a data set via a process that resembles how the human brain works. Neural networks relate to systems of neurons that are either artificial or organic.
Convolutional Neural Networks are unique neural networks primarily used for deep learning image classification, image clustering, and object detection deep learning. DNNs allow unsupervised development of hierarchical deep learning image representations. But to attain the best accuracy, deep convolutional neural networks are more preferred than any other neural networks.
In other words, a Deep Learning Convolutional Neural Network (CNN) is a deep learning neural network implemented for processing organised arrays of data like images. CNN is widely used in computer vision, and now it has transformed into state-of-the-art for various visual applications like image classification. Also, it got successful in natural language processing for text classification.
In deep learning, a convolutional neural network (brief as CNN or ConvNet) represents a class of deep neural networks typically employed to analyse visual imagery. When discussing a neural network, we would think about the matrix multiplications; however, this is not the case with CNN. It implements a special technique known as Convolution. From a mathematics viewpoint, convolution is a mathematical operation performed on two functions that generates a third function that shows how the shape of one is altered by the other.
Convolutional neural networks choose the patterns in the input deep learning image efficiently. The patterns include lines, circles, gradients, faces, and eyes. With this property, convolutional neural networks become so efficient for computer vision. Contrasting formerly released computer vision algorithms, CNN can directly operate on a raw image and doesn’t require any pre-processing.
A CNN is a feed-forward neural network, usually consisting of up to 20 or 30 layers. Moreover, the huge power of a convolutional neural network derives from a unique type of layer known as the convolutional layer. CNN is extensively used for image identification and classification. It influences the present-day healthcare industry and enhances the outcome of patients’ cures.
a. Convolutional Layer
The fundamental building block in a convolutional neural network is a convolutional layer. You can envisage a convolutional layer as several tiny square templates known as convolutional kernels sliding across the image and looking for patterns. The kernel will return a huge positive value for the specific part of the image that matches the kernel’s pattern. The kernel will return 0 or a smaller value if there is no match.
Plenty of convolutional layers stacked on one another are present in CNNs. Each of these layers is competent in identifying more refined shapes. It is possible to identify transcribed digits using 3 or 4 convolutional layers. While using 25 convolutional layers, it is possible to differentiate human faces via face detection deep learning.
The use of convolutional layers in a CNN resembles the construction of the human visual cortex. Its construction shows a sequence of layers that processes an incoming image and gradually identifies more complex features.
Applications of Convolutional Neural Networks:
Regular Neural Networks (RNN)
Convolutional Neural Networks (CNN)
RNN deals with random input/output lengths.
CNN deals with fixed-size inputs and produces fixed-size outputs.
RNNs can use their internal memory to process random sequences of inputs.
CNN is a kind of feed-forward artificial neural network consisting of variants of multi-layer perceptrons. These perceptions are formulated to use the least amounts of pre-processing.
RNN uses time-series information; for example, what I spoke last will influence what I will speak next.
CNN employs a connectivity pattern between its neurons. It is inspired by the arrangement of the animal visual cortex, whose distinct neurons are organised to react to overlapping regions overlaying the visual field.
RNN transforms an input by traversing it through a sequence of hidden layers. Every layer is composed of a set of neurons. Moreover, every layer is robustly connected to all the neurons in the preceding layer. Ultimately, there exists a last fully connected layer known as the output layer. The output layer depicts the predictions.
In CNN, first of all, every layer is organised in three dimensions: depth, width, and height. The neurons in one layer don’t connect to all the neurons in the succeeding layer but only connect to a minor region. Finally, the final output will be contracted to a single vector of probability scores, structured across the depth dimension.
RNNs are perfect for text and speech analysis.
CNNs are perfect for video and image processing.
A recurrent Neural Network (RNN) is a category of Neural Networks where outputs from the preceding step are provided as inputs to the present step.
The deep learning algorithms are assimilated into famous applications like voice search, Siri, and Google Translate. Like convolutional neural networks (CNNs) and feedforward, recurrent neural networks use training data for learning purposes. These networks are categorised by memory as they accept information from previous inputs to control the present input and output.
All inputs and outputs are independent of one another in traditional neural networks. But in those cases, when it is essential to foresee the succeeding word of a sentence, you will need previous words. So, it is necessary to recollect and remember the previous words. Therefore, RNN came into the picture and solved this problem using a Hidden Layer. The key and most significant feature of the RNN is the ‘Hidden state’ that remembers information about the sequence.
RNN contains a memory that stores all information regarding what was already calculated. For each input, it uses the same parameters. It carries out the same task on every input or hidden layer to generate the output. Consequently, it decreases the intricacy of parameters, contrasting other neural networks.
A unique characteristic of recurrent networks is the ability to share parameters over all the network layers. RNN adopts a backpropagation through time (BPTT) algorithm to define the gradients. Its method is slightly dissimilar from traditional backpropagation because it is explicit to sequence data. Both BPTT and traditional backpropagation use the same principles, i.e., the model trains itself by computing errors after mapping the output layer to the input layer. With these calculations, we can fine-tune and use the model's parameters correctly.
Let’s understand the RNN deep learning example. For example, we have the idiom “As sick as a dog”. This idiom is usually used to express when someone is very ill. It must be expressed following the mentioned order to have the idiom make sense. Consequently, recurrent networks must account for the location of every word in the idiom. They utilise that information for the prediction of the next word in order.
Types of recurrent neural networks

Another area where Deep Learning in the Neural Networks industry will show growth is pattern recognition. Deep Learning is getting more detailed in terms of pattern recognition. Currently, we are not just discussing deep learning image recognition but its entire spectrum of identifying objects, shapes, and patterns and also illustrating them.
Discerning patterns on images or employing deep recurrent neural networks and demonstrating their time-series features, variable significance, causal inference, and centrality statistics are the prominent phases of deep learning advancement.
Deep Learning of Neural Networks industry growth will also be seen in Metaverse. The use of Deep Learning to design digital 3D worlds will perhaps be another huge aspect we will observe in 2022-23.

Moreover, the development of Audio Deep Learning practice and NLP will facilitate AI-aided music composers with myriad options and enhanced workflows.

The most commonly used algorithms in Deep Learning are recurrent neural network (RNN), convolutional neural network (CNN), Deep belief network (DEB), Long Short-Term Memory networks (LSTM), stacked autoencoders, and Deep Boltzmann machine (DBM), etc.
It depends on your expertise level and how well you grasp it. Typically, it takes 6 months to 1.5 years to learn Deep Learning.
Deep Learning is termed ‘Deep’ due to multiple additional ‘layers’ added to learn from the data. Whenever a deep learning model is learning, it updates the weights across an optimisation function. Essentially, a Layer is a transitional row of ‘Neurons’. A deep learning method sequentially learns categories via its hidden layer architecture. Firstly, it establishes low-level categories like letters and then moves to slightly higher-level classes such as words. Finally, it moves to the higher-level categories like sentences.
Deep learning is a significant component of data science that encompasses statistics and predictive modelling. It is advantageous to data scientists who want to collect, analyse and interpret vast amounts of data. In those cases, deep learning makes the processes easier and faster. Deep learning improves efficiency and productivity by improving response times. Also, it improves relationships and communication with the clients by recording their emotions and adapting the treatment accordingly.
With the advent of deep learning, image classification has turned more widespread. The image classification process allows machines to look at an image and allocate a correct label. Image classification with deep learning typically involves convolutional neural networks (CNNs). In CNN's, the nodes in the hidden layers don't always share their outcome with every node in the succeeding layer. Deep learning permits machines to recognise and extract features from the images.
Traditional machine learning algorithms work on low-end machines, but deep learning algorithms hugely depend on high-end machines. Deep learning algorithms can integrally do many matrix multiplication operations, whereas machine learning algorithms can’t do such operations. Compared to machine learning, deep learning decreases the effort of developing a new feature extractor for each problem.
One of the most efficient ways to improve the neural network is to train a larger network or input more data. This only works up to some point since you would run out of data or your network becomes so big that it takes a long time to train. But deep learning trains a neural network in less time. Also, it offers faster computation and provides improved algorithms.
The history of deep learning traces back to 1943, when Walter Pitts and Warren McCulloch developed a computer model depending on the neural networks of the humanistic brain. They used algorithms and mathematics, which they named ‘threshold logic’ to resemble the thought process. Subsequently, deep learning has steadily evolved with two noteworthy breakthroughs in its development.
On Keras, deep learning models are developed using neural networks. The inputs are fed to a neural network which is subsequently processed in the hidden layers through weights adapted during training. Subsequently, the model presents a prediction. The user need not mention what patterns to discover; the neural network learns automatically. The sequential method is the simplest way to develop a model in Keras.
Deep learning is a type of machine learning that can be used to detect features in imagery. It uses a neural network—a computer system designed to work like a human brain—with multiple layers; each layer can extract one or more unique features in the image. Processing is often distributed to perform analysis promptly. Deep learning workflows for feature extraction can be performed directly in ArcGIS Pro, or processing can be distributed using ArcGIS Image Server as a part of ArcGIS Enterprise.
One of the best examples of deep learning is virtual assistants that use a deep learning model to translate the language and speech of human speech. To navigate an autonomous car, for example, a Tesla, one requires a human-like experience and skill. For that, deep learning is useful. This technology is also used in developing a vision for driverless, autonomous cars. Other examples of deep learning are face recognition and chatbots.
Deep learning will become mainstream like SVM. But, the complexity of deep learning and its requirements for the huge amount of data still must be solved before this technology becomes the foremost choice for machine learning algorithms. Since deep learning positively influences fields like speech recognition, computer vision, natural language processing, etc., it will gradually substitute machine learning in the future.
Deep learning is considered the subsequent logical step in the development of machine learning. This technology equips computers with the ability to understand concepts and human language, similar to how humans do. Being a game-changer, it enables computers to learn how humans learn and can be used for applications ranging from computer vision to computational ecology. Thus, staying abreast with the latest technology trends is the perfect time to learn and use deep learning technology.
Deep learning uses supervised learning for object detection and image classification. A neural network can be used as a semi-supervised deep neural network. Autoencoders are neural networks that can be used for image reconstruction and compression; they are self-supervised learning neural networks. Thus, deep learning can be supervised, unsupervised, self-supervised, semi-supervised, or reinforced depending on how the neural network is utilised.
