Neural networks trained on large amounts of data have led to incredible technological leaps affecting nearly every part of our lives.

These advances have come at a cost — namely the interpretability and explainability of data models. Corresponding with the complexity of the operation, the criteria for “choosing” a given output for an input becomes rather mysterious, leading some to refer to neural networks as a “black box” method.

Deep neural networks work so marvelously because they learn efficient representations of data, and they are intentionally constrained to capture complex, non-linear patterns in the data. The trade off of recognizing…
