## Distortion (a type of generalization): suppose instead of

*f*(*x*) we report a random number from a distribution D*f*## Example: choose a value

*y*uniformly in the interval [*f*(*x*)-*a*,*f*(*x*)+*a*]## Suppose we consider

*f*(*x*) identified if |*y*-*f*(*x*)| ## Properties of

*f*and D may enable us to bound*f*(*z*) (a different value) definitively## Properties of

*f*and D may enable us to bound*f*(*z*) probabilistically
