pycobra: A Python toolkit for ensemble regression analysis and visualisation

We introduce \texttt{pycobra}, a Python library devoted to ensemble regression and visualisation. Its main assets are the implementation of the COBRA algorithm (an ensemble method introduced by Biau et al, 2016), a flexible and generic interface to compare most regression methods available in Python libraries (including, but not limited to, \texttt{scikit-learn}), and visualisation tools based on Voronoi tessellations. \texttt{pycobra} is released under the MIT open-source license and can be downloaded from the Python Package Index (PyPi) and Machine Learning Open Source Software. The current development (along with Jupyter notebooks) is available at \href{https://github.com/bhargavvader/pycobra}{https://github.com/bhargavvader/pycobra}.
