1. What is Metric Learning? Many approaches in machine learning require a measure of distance between data points. Traditionally, practitioners would choose a standard distance metric (Euclidean, City-Block, Cosine, etc.) using a priori knowledge of the domain. However, it is often difficult to design metrics that are well-suited to the particular data and task of interest. Distance metric learni
