Machine Learning libraries are available in many programming languages but Python is best suited for Machine Learning purposes. Python is the most user-friendly and easy-to-manage language and has a large developer community. In this, we will give you a brief introduction to the best Python Libraries for Machine Learning.
Python libraries are collections of modules that contain useful codes and functions, eliminating the need to write them from scratch. Below is the list of Python Libraries for Machine Learning:
PyTorch
TensorFlow
NumPy
Pandas
Keras
1. PyTorch
PyTorch is an open-source Machine Learning Python library based on the C programming language framework, Torch. It is mainly used in ML applications that involve natural language processing or computer vision. PyTorch is known for being exceptionally fast at executing large, dense data sets and graphs.
2. TensorFlow
TensorFlow’s open-source Python library specializes in what’s called differentiable programming, meaning it can automatically compute a function’s derivatives within a high-level language. Both machine learning and deep learning models are easily developed and evaluated with TensorFlow’s flexible architecture and framework. TensorFlow can be used to visualize machine learning models on both desktop and mobile.
3. NumPy
NumPy is a popular Python library for multi-dimensional array and matrix processing because it can be used to perform a great variety of mathematical operations. Its capability to handle linear algebra, Fourier transform, and more, makes NumPy ideal for machine learning and artificial intelligence (AI) projects, allowing users to manipulate the matrix to easily improve machine learning performance. NumPy is faster and easier to use than most other Python libraries.
4. Pandas
Pandas is another Python library that is built-on top of NumPy, responsible for preparing high-level data sets for machine learning and training. It relies on two types of data structures, one-dimensional (series) and two-dimensional (DataFrame). This allows Pandas to be applicable in a variety of industries including finance, engineering, and statistics. Unlike the slow-moving animals themselves, the Pandas library is quick, compliant, and flexible.
5. Keras
Keras provides a Python interface of TensorFlow Library especially focused on AI neural networks. The earlier versions also included many other backends like Theano, Microsoft cognitive platform, and PlaidMl. Keras contains standard blocks of commonly used neural networks, and also the tools to make image and text processing faster and smoother. Apart from standard blocks of neural networks, it also provides re-occurring neural networks.
