Machine learning introduces complex algorithms which affect our daily life. Despite all the benefits of Machine Learning, there are risks that are introduced which can manifest themselves as a bias towards customers or users, in the form of racism, sexism and other forms of discrimination.

This issue is explored in detail by Adam who proposes a framework for the ethical testing for bias.
