Add characteristics to the "Actions" available to a model notification recipient that indicate whether the action is negative (e.g. the notification is marked as "not useful" or disabled by the recipient) or positive (marked as "acknowledged", a message sent to student, etc.) There might also be "neutral" actions, e.g. viewing a detailed report. Calculations of these actions should be displayed with the model accuracy to summarize whether users are finding the model insights helpful or not.
