I have created PYBANDIT library to host a bunch of multiarmed bandit algorithms written using python. I enjoy contributing to opensource. Here are a selection of projects that I am currently contributing to.
NumPy is the fundamental package for scientific computing in Python.
Flexible and powerful data analysis / manipulation library for Python, providing labeled data structures.
PyTorch is a Python package that provides tensor computation (like NumPy) with strong GPU acceleration.
scikit-learn is a Python module for machine learning built on top of SciPy and is distributed under the 3-Clause BSD license.
SciPy is a scientific computation library that uses NumPy underneath.
