Matrixcalculus / Hardcore Data Science
Matrixcalculus.org is a tool by data scientists for data scientists. It enjoys great popularity in the AI community. Matrixcalculus.org is used in almost all areas of science and technology around the world, including research teams at Google, Facebook, and MIT.
Matrix Calculus is the name given to the problem of expressing the derivative of a function given as a matrix algebra expression back as a matrix algebra expression. Sounds unwieldy, but it plays a big role for Data Science, especially for machine learning. This is shown by the user numbers. Every year, several million matrix derivatives are calculated by over 100,000 users with Matrixcalculus.org.
But don’t worry, you don’t have to mess around with matrix algebra for your data science projects. We’ll take care of that for you.
