Sensitivity analysis

Sensitivity analysis is used in Asa H and other AIs for/during things like feature discovery, generalization, forgetting, abstraction, etc. How sensitively utility depends upon a given input or group of inputs is one important measure.  In many tasks and environments that Asa H has explored there are far more input variables than output variables (actions).  For that reason sensitivity of output variables to variations in input variables and clusters of input variables (features) is also a valuable measure.
