Many neural networks and deep learning algorithms are also used to streamline finance analysis.

Before getting deep into deep learning vs neural network, let’s go through the details of neural networks.

What is a Neural Network?

The structure of the human brain inspires a Neural Network. It is essentially a Machine Learning model (more precisely, Deep Learning) that is used in unsupervised learning. A Neural Network is a web of interconnected entities known as nodes wherein each node is responsible for a simple computation. In this way, a Neural Network functions similarly to the neurons in the human brain. 

Read: Deep Learning vs Neural Network

Also known as an artificial neural network, it is a technical machine learning model commonly used in supervised learning.

Neural networks are categorized into three main types. They are sequence learning, classification, and function approximation.  Examples of different types of neural networks are Perceptron, Hopfield, convolutional neural networks, autoencoders, Boltzmann machines, self-organizing maps, restricted Boltzmann machines, deep belief networks, recurrent neural networks, etc. The neural network’s key application is classification.

Technically, a neural network is a kind of machine learning model that is used in supervised learning. These deep learning neural networks estimate the way how neurons work in the human brain. They connect various nodes, and each node is tasked with a direct computation.

In other words, neural networks represent a collection of algorithms developed to identify patterns. They classify or group raw input to comprehend sensory data through machine perception. The real-world data, like texts, images, sounds, etc., should be transformed into vectors to allow neural networks to identify the patterns.

Neural networks can’t learn the fundamental rules if your dataset is small.  Its internal structure is difficult to comprehend.

The following benefits help you to compare neural networks and deep learning.

1. Stores information on the entire network:

In conventional programming, data is stored on the network instead of a database. The neural networks make sure the entire network’s operation is not stopped when a few pieces of data disappear from a location.

They provide good fault tolerance. They make sure the corruption of one or multiple artificial network cells doesn’t impact the output production. Hence, networks can better tolerate errors.

2. Distributed memory:

Two aspects are important to allow an artificial neural network to learn. They outline the examples and train the network as per the anticipated output by offering related examples. These examples are directly correlated with the network’s development. neural networks and deep learning

3. Can work with incomplete knowledge:

The output produced by the data may be incomplete. The neural networks can work on this data to identify the missing aspect and work accordingly.

4. Avoids network corruption:

A network can slow down or degrade over time. The neural networks protect the data from this corruption.

5. Trains a machine:

An artificial neural network can comment on comparable situations. Consequently, they can learn from these experiences and make decisions.

6. Supports parallel processing:

Their ability to parallel process helps them to accomplish multiple tasks simultaneously. It is one of the prominent aspects that differentiates deep learning neural networks.

Machine Learning vs Neural Network: Key Differences

Let’s look at the core differences between Machine Learning and Neural Networks.

1. Machine Learning uses advanced algorithms that parse data, learns from it, and use those learnings to discover meaningful patterns of interest. Whereas a Neural Network consists of an assortment of algorithms used in Machine Learning for data modelling using graphs of neurons.

2. While a Machine Learning model makes decisions according to what it has learned from the data, a Neural Network arranges algorithms in a fashion that it can make accurate decisions by itself. Thus, although Machine Learning models can learn from data, in the initial stages, they may require some human intervention.

Neural networks do not require human intervention as the nested layers within pass the data through hierarchies of various concepts, which eventually makes them capable of learning through their own errors.

3. As we mentioned earlier, Machine learning models can be categorized under two types – supervised and unsupervised learning models. However, Neural Networks can be classified into feed-forward, recurrent, convolutional, and modular Neural Networks.

4. An ML model works in a simple fashion – it is fed with data and learns from it. With time, the ML model becomes more mature and trained as it continually learns from the data. On the contrary, the structure of a Neural Network is quite complicated. In it, the data passes through several layers of interconnected nodes, wherein each node classifies the characteristics and information of the previous layer before passing the results on to other nodes in subsequent layers.

5. Since Machine Learning models are adaptive, they are continually evolving by learning through new sample data and experiences. Thus, the models can identify the patterns in the data. Here, data is the only input layer. However, even in a simple Neural Network model, there are multiple layers.

The first layer is the input layer, followed by a hidden layer, and then finally an output layer. Each layer contains one or more neurons. By increasing the number of hidden layers within a Neural Network model, you can increase its computational and problem-solving abilities.

6. Skills required for Machine Learning include programming, probability and statistics, Big Data and Hadoop, knowledge of ML frameworks, data structures, and algorithms. Neural networks demand skills like data modelling, Mathematics, Linear Algebra and Graph Theory, programming, and probability and statistics.

7. Machine Learning is applied in areas like healthcare, retail, e-commerce (recommendation engines), BFSI, self-driving cars, online video streaming, IoT, and transportation and logistics, to name a few. Neural Networks, on the other hand, are used to solve numerous business challenges, including sales forecasting, data validation, customer research, risk management, speech recognition, and character recognition, among other things.
