Machine Learning (ML)

ML is the study of how to build computer programs that can learn to detect patterns from data.


In the broadest terms my research spans the areas of Artificial Intelligence (AI) and Machine Learning (ML) which can be seen highly related, independent, or identical research fields depending on who you are.

My approach to understanding the relationship is summarized in this picture which I use in my courses on the subject.
