A mathematical framework developed by researchers at the Massachusetts Institute of Technology and Microsoft Research aims to quantify and evaluate the understandability of a machine learning model's explanations for its predictions.
The framework, called ExSum (explanation summary), can evaluate a rule on an entire dataset. ExSum enables the user to see if a rule holds up based on three metrics: coverage, or how broadly applicable the rule is across the entire dataset; validity, or the percentage of individual examples that agree with the rule; and sharpness, or how precise the rule is.
Said MIT's Yilun Zhou, "Before this work, if you have a correct local explanation, you are done. You have achieved the holy grail of explaining your model. We are proposing this additional dimension of making sure these explanations are understandable."
