Evaluating the interpretability of threshold operators
Abstract Weighted Threshold Operators are n-ary operators that compute a weighted sum of

Towards Knowledge-driven Distillation and Explanation of Black-box Models.
We introduce and discuss a knowledge-driven distillation approach to explaining black-box
models by means of two kinds of interpretable models. The first is perceptron (or threshold) …
