We spend our time substituting data-driven machine learning approaches for legacy human curated set of business rules that are difficult to scale as well as to incrementally and systematically improve. However, not all is always without issues with machine learning models as they bring their own unique set of challenges. One of the main difficulties that we have to deal with on daily basis is to understand what changes to expect from a new “black-box” machine learning model. It is quite easy to see that weights in neural network…
