This website is intended to help anyone master the math of machine learning through consistent practice.

A set of tags is associated with each problem. For example problems related to understanding neural networks will be tagged with neural networks.

A difficulty rating will also be associated with each problem on a scale of 0 to 5 with 5 being the most difficult. A difficulty rating of 0 is intended to take a few minutes to solve while a difficulty rating of 5 may take an hour or require a highly non-obvious insight.

Problem contributions, corrections and comments are welcome. Please file an issue or pull request at the project repository.
