2. Keras

Keras is an accessible API for neural networks. It is based in Python, and you can run it on CNTK, TensorFlow as well as Theano. It is written in Python and follows best practices to reduce the cognitive load. It makes working on deep learning projects more efficient. 

The error message feature helps developers in identifying any mistakes and fixing them. As you can run it on top of TensorFlow, you get the benefit of the flexible and versatile application too. This means you can run Keras in your browser, on Android or iOS through TF Lite, as well as through their web API. If you want to work on deep learning projects, you must be familiar with Keras. 

Imagine that you need a deep learning framework that facilitates rapid prototyping, works efficiently on CPUs and GPUs, and supports convolutional and recurrent networks. Keras is the perfect library for implementing open-source AI projects fulfilling these needs.

Keras doesn’t deal with simple low-level operations, unlike independent open-source AI projects. It uses libraries from related deep learning frameworks such as Theano or Tensorflow as backend engines to perform all low-level computations (like convolutions, tensor products, and many more).

Keras is one of those AI mini projects with source code that provides easy and rapid backend access. This is because it boasts ready-to-use interfaces. No need to commit to a specific framework because you can rapidly transit back and forth between the several backends.

Keras also provides a high-level API that looks after developing models, stating layers, and configuring different models. This API’s loss and optimizer functions help you to develop models; the API’s fit function helps you to train the process.

It is an open-source project developed by the MILA (Montreal Institute for Learning Algorithms) at the Université de Montréal. It is a fundamental library for working on Deep Learning projects and wrapper libraries in Python.

Alternatively, it works as a compiler for performing mathematical expressions in Python. It accepts your data structures and transforms them into efficient code. The resultant code uses NumPy, native code (C++), and efficient native libraries like BLAS. All these components help the code run as quickly as possible on GPUs and CPUs.

It uses clever code optimizations to obtain the maximum possible performance from the hardware. It becomes easy to deal with this AI project with source code if you know the fundamentals of mathematical optimizations in Python code. Moreover, Theano offers detailed installation instructions for major operating systems like Windows, Linux, and OS X.

5. Chainer

Chainer is a Python-based framework for working on neural networks. It supports multiple network architectures, including recurrent nets, convnets, recursive nets, and feed-forward nets. Apart from that, it allows CUDA computation so you can use a GPU with very few lines of code. 

You can run Chainer on many GPUs too if required. A significant advantage of Chainer is it makes debugging the code very easy, so you won’t have to put much effort in that regard. On Github, Chainer has more than 12,000 commits, so you can understand how popular it is. 

Chainer is an (open source) deep learning framework written using CuPy and NumPy Python libraries. Japanese venture company “Preferred Networks” in collaboration with Microsoft, Intel, IBM, and Nvidia manages its development.

Chainer is flexible and intuitive. You need exclusively designed operations if the network contains complex control flows like loops and conditionals, in the define-and-run approach. But in this approach, the programming language’s native constructs, like for loops and if statements can be utilized to designate such flow. So, Chainer’s flexibility is useful for executing recurrent neural networks.

Another benefit of this AI project with source code is the simplicity of debugging. Usually, it is challenging to determine the fault an error occurs in the training calculation when using the define-and-run approach. This is because the code written to define the actual position of the error and the network are separated.

6. Caffe

Caffe is a product of Berkeley AI Research and is a deep learning framework that focuses on modularity, speed, and expression. It is among the most popular open-source AI projects in Python. 

It has excellent architecture and speed as it can process more than 60 million images in a day. Moreover, it has a thriving community of developers who are using it for industrial applications, academic research, multimedia, and many other domains. 

7. Gensim

Gensim is an open-source Python library that can analyse plain-text files for understanding their semantic structure, retrieve files that are semantically similar to that one, and perform many other tasks. 

It is scalable and platform-independent, like many of the Python libraries and frameworks we have discussed in this article. If you plan on using your knowledge of artificial intelligence to work on NLP (Natural Language Processing) projects, then you should study this library for sure. 

Gensim stands for Generate Similar. It is a python-based open-source framework for natural language processing and unsupervised topic modeling. It extracts semantic concepts from documents. It can also manage extensive text collections. So, it differentiates itself from other ML software packages that use memory processing.

It is one of the best AI projects for beginners with source code that improves processing speed. This is because it offers efficient multicore implementations for different algorithms. It features more text processing features than many other packages like R, Scikit-learn, etc.

It uses the best models and modern statistical machine learning (like Creating word or document vectors) to perform various complex tasks. It also detects semantic structure in plain-text materials.

Gensim is one of the popular AI projects for beginners with source code because it has been used in many applications including Word2vec, fastText, Latent Semantic Analysis (LSA),  Latent Dirichlet Allocation (LDA), and Term Frequency-Inverse Document Frequency (TF-IDF).

Frequently Asked Questions (FAQs)

1Why is it recommended to use Python in data science and machine learning and AI?

One of the key reasons Python is by far the most popular AI programming language is the large number of libraries available. A library is a pre-written computer program that allows users to access certain functionality or conduct certain activities. Python libraries provide basic stuff so that coders don't have to start from scratch every time. Because of the low entry barrier, more data scientists can quickly learn Python and start utilizing it for AI research without putting in a lot of work. Python is not only simple to use and understand, but it is also quite versatile. Python is incredibly easy to read, thus any Python developer can comprehend and alter, copy, or share the code of their peers.

2What problems can machine learning AI solve?

One of the most basic uses of machine learning is spam detection. Our email providers automatically filter undesired spam emails into an unwanted, bulk, or spam inbox in most of our inboxes. Recommender systems are among the most common and well-known applications of machine learning in everyday life. Search engines, e-commerce sites, entertainment platforms, and a variety of web and mobile apps all leverage these systems. The major issues that any marketer faces are client segmentation, churn prediction, etc. Over the last few years, advances in deep learning have sped up progress in image and video identification systems.

3How many types are available in machine learning?

One of the most common categories of machine learning is supervised learning. The machine learning model is trained on labelled data in this case. The ability to deal with unlabeled data is a benefit of unsupervised machine learning. Reinforcement learning is directly inspired by how people learn on data in their daily lives. It includes a trial-and-error algorithm that builds upon itself and learns from different scenarios.
