In Quest of Performance Metrics for Intelligent Systems- A Challenge that Cannot be Met with Existing Methods
Lotfi A. Zadeh · 2002
Abstract : As we move further into the realm of intelligent systems, the problem of devising performance metrics for assessing machine intelligence looms larger and larger in importance. The problem is there, but does it have a solution? A somewhat unorthodox view which is articulated in the following is that (a) complete solution is beyond the reach of existing methods; and (b) that a prerequisite to solving the problem is a better understanding of a broader problem, namely, the basic problem of concept definability. To this end, what is presented in the following is a sketch of what may be called a theory of hierarchical definability, or THD for short.
