Explanations of artificial explanations can be simplified by controlling the number of variables, but the complexity in how they are visualized can still impede quick interpretation. We quantitatively modeled the cognitive load of machine learning model explanations as visual chunks and introduce Cognitive-GAM (COGAM) to balance between explanation accuracy and cognitive load.
Congratulations to team members Ashraf Abdul and collaborators Christopher von der Werth and Mohan Kankanhalli!
|Sparse Linear Models (sLM)||Cognitive-GAM (COGAM)||Generalized Additive Models (GAM)|
|Lowest Cognitive Load, but
|Balances Cognitive Load and Accuracy
by increasing accuracy with marginal increase in cognitive load
|Highest Cognitive Load, but
