    Machine learning (ML) focuses on providing machines with the ability to learn without being programmed and improve their decision-making capability over each iteration through experience. Here, we will discuss the best machine learning frameworks. ML is the subset of artificial intelligence, and it has several real-world applications.

    In other words, machine learning enables machines to learn just like humans. For example, natural language processing (NLP), pattern recognition, image classification, clustering, and regression are all different applications of machine learning. Also, ML is extensively used for performing data science, and it helps businesses perform predictive data analysis, make business decisions, and forecast the future.

    In this article, we will be discussing the best machine learning frameworks that machine learning engineers and data scientists use to develop robust machine learning models. But before moving to that, let's quickly overview the types of algorithms that machine learning uses.

    Types of Machine Learning Algorithms

    Machine learning can be performed through a set of algorithms. These algorithms are of three types:

    1. Supervised Machine Learning

    Supervised machine learning trains a machine by providing a set of data and the expected outcome, i.e., we already labeled the data. The machine builds a model based on the training data set. Once the model is built, another data set (testing data set) is fed to the machine to check the accuracy of the model.

    Examples of supervised machine learning algorithms are classification algorithms, like Support Vector Machines, decision trees, linear classifiers, and regression algorithms, like linear regression and polynomial regression.

    2. Unsupervised Machine Learning

    This type of algorithm provides no training to a machine. Hence, the machine finds similarities and patterns in the data all by itself (without any form of supervision). Also, unsupervised learning is more complex than supervised learning.

    Some examples of unsupervised machine learning algorithms are clustering algorithms, like K-means clustering, DBScan, dimensionality reduction, and Association rules, like Apriori and ECLAT.

    3. Reinforcement Machine Learning

    The third type of machine learning is reinforcement learning. It is also the most complex of the trio. It involves an agent that has to take actions in a specific environment to ensure maximum rewards. The reward is cumulative and follows certain rules.

    Game theory, information theory, multi-agent systems, and statistics use reinforcement learning. Reinforcement machine learning is also referred to as neuro-dynamic or approximate dynamic programming. Markov Decision Process and Q learning are vital learning models in reinforcement learning.

    Relationship Between Artificial Intelligence, Machine Learning, and Deep Learning

    Machine learning is a subset of artificial intelligence, and deep learning is a subset of machine learning. Thus, we can say that both machine learning and deep learning are subsets of artificial intelligence. You can understand the relation between the three from the below image: relation between machine learning and deep learning Also, you can check out our AI vs ML vs Deep Learning article that highlights all the key differences between the three in detail.

    Top 12 Machine Learning Frameworks

    There are many machine learning frameworks out there. Thus, it will become difficult for you to find one that best suits your needs, especially if you're new to it. Therefore, to make the selection process easier for you, we have listed the best machine learning frameworks along with their brief overviews as follows:

    1. TensorFlow


    We'll start our list of the best machine learning frameworks with TensorFlow, which is an open-source machine learning and deep learning framework developed by Google. Its libraries use graphs to describe workflows and complex networks in a simple manner.

    TensorFlow finds use in both research projects and real-world applications. The key highlight of TensorFlow is its ability to create neural networks. Also, TensorFlow works on all major operating systems, including Windows, macOS, and Linux. TensorFlow is built using the C++ programming language, and it supports various programming languages, including Python , Java, and C. The machine learning framework is ideal to use for image recognition, image search, language translation, and speech recognition.

    2. Keras


    Keras is a deep learning framework that has broad community support. It is written in Python and supports many neural-network computation engines, especially Convolutional Neural Networks. Keras is used along with low-level computation libraries like TensorFlow as a high-level API. Also, it comes with an interface that is easier to use as compared to TensorFlow.

    The other ‘Backend’ engines/libraries that support Keras are Theano and CNTK. Developers can create new modules as a set of classes and functions using Python in Keras. The existing stand-alone modules can be used to create new models.

    With Keras, code deployment is fast, and it supports many devices, including Raspberry Pi. Moreover, you can use Keras with single or multiple GPUs at the same time. The base of Keras is the ‘Model,’ which defines the whole network graph. You can use the same model or add more layers to it to suit your requirements. You can build a simple sequential model with the following steps:

    • Creating a sequential model
    • Convolution layer
    • MaxPooling layer
    • Dense layer
    • Dropout layer
    • Network compilation, training, and evaluation
