List of the Best Python Libraries for Machine Learning in 2020

Machine Learning (ML) and Artificial Intelligence (AI) are spreading across various industries, and most enterprises have started actively investing in these technologies. With the expansion of volume as well as the complexity of data, ML and AI are widely recommended for its analysis and processing. AI offers more accurate insights, and predictions to enhance business efficiency, increase productivity and lower production cost.

AI and ML projects differ from conventional software projects. It varies based on the technology stack, the skills for ML-based projects and the demand for in-depth research. For building ML and AI outline, you have to choose a programming language, which should be flexible, stable and include predefined libraries & frameworks. Python is one of such languages wherein you can see many Python machine learning and Artificial Intelligence projects developing today. Here we have listed the top 8 best Python libraries that could be used for machine learning.

Why Python is preferred for Machine Learning and AI?

Python supports developers during the entire software development
lifecycle in order to be productive as well as confident about the product they are building. Python offers plenty of benefits for building AI and ML projects. Here are some sample benefits:

These features add value to the overall popularity of the programming language. The extensive collections of Python libraries for machine learning simplify the development overhead and reduce the development time. Its simple syntax as well as readability supports rapid testing of complex process and makes the language simple to understand for non-programmers. PHP is considered a competitor of Python in terms of web
and app development. But in terms of AI and ML you need specific PHP
development expertise
 who have worked on the ML libraries.

Best Python Libraries for Machine Learning and AI

Implementing ML and AI algorithms require a well-structured & well-tested environment to empower developers to come up with the best quality coding solutions. To reduce development time, there are countless Python libraries for machine learning. Python library or framework is a pre-written program that is ready to use on common coding tasks. Let us become familiar with the best Python machine learning libraries:

1. Tensor Flow Python

TensorFlow is an end-to-end python machine learning library for performing high-end numerical computations. TensorFlow can handle deep neural networks for image recognition, handwritten digit classification, recurrent neural networks, NLP (Natural Language
Processing), word embedding and PDE (Partial Differential Equation). TensorFlow Python ensures excellent architecture support to allow easy computation deployments across a wide range of platforms, including desktops, servers, and mobile devices.Abstraction is the major benefit of TensorFlow Python towards machine learning and AI projects. This feature allows the developers to focus on comprehensive logic of the app instead of dealing with the mundane details of implementing algorithms. With this library, python developers can now effortlessly leverage AI and ML to create unique responsive applications, which responds to user inputs like facial or voice expression.

2. Keras Python

Keras is a leading open-source Python library written for constructing neural networks and machine learning projects. It can run on Deeplearning4j, MXNet, Microsoft Cognitive Toolkit (CNTK), Theano or TensorFlow. It offers almost all standalone modules including optimizers, neural layers, activation functions, initialization schemes, cost functions, and regularization schemes. It makes it easy to add new modules just like adding new functions and classes. As the model is already defined in the code, you don’t need to have a separate model config files.Keras makes it simple for machine learning beginners to design and develop a neural network. Keras Python also deals with convolution neural networks. It includes algorithms for normalization, optimizer, and activation layers. Instead of being an end-to-end Python machine learning library, Keras functions as a user-friendly, extensible interface that enhances modularity & total expressiveness.

3. Theano Python

Since its arrival in 2007, Theano has captured the Python developers and researchers of ML and AI.At the core, it is a well-known scientific computing library that allows you to define, optimize as well as evaluate mathematical expressions, which deals with multidimensional arrays. The fundamental of several ML and AI applications is the repetitive computation of a tricky mathematical expression. Theano allows you to make data-intensive calculation up to a hundred times faster than when executing on your CPU alone. Additionally, it is well optimized for GPUs, which offers effective symbolic differentiation and includes extensive code-testing capabilities.When it comes toperformance, Theano is a great Python machine learning library as it includes the ability to deal with computations in large neural networks. It aims to boost development time and execution time of ML apps, particularity in deep learning algorithms. Only one drawback of Theano in front of TensorFlow is that its syntax is quite hard for the beginners.

4. Scikit-learn Python

Scikit-learn is another prominent open-source Python machine learning library with a broad range of clustering, regression and classification algorithms. DBSCAN, gradient boosting, random forests, vector machines, and k-means are a few examples. It can interoperate with numeric and scientific libraries of Python like NumPy and SciPy.It is a commercially usable artificial intelligence library. This Python library supports both supervised as well as unsupervised ML. Here is a list of the premier benefits of Scikit-learn Python that makes it one among the most preferable Python libraries for machine learning:

  • Reduction of dimensionality
  • Decision tree pruning & induction
  • Decision boundary learning
  • Feature analysis & selection
  • Outlier detection & rejection
