>> The basic idea is that a user wants to identify a particular object
from a
large set that all share common characteristics ... the program also
eliminates all attributes that are no longer relevant to objects that
share the selected attribute's value. For example if all birds with
yellow eyes happen to have the same kind of beaks, the beak attribute
would be eliminated since it will not help reduce the search any
further. <<
It sounds like he has re-discovered functional dependency or determiners. "If I know A then I can determine B", written as A -> B. You look for a minimal set of attributes that can determine all the others.
Or he might have re-discovered statistical correlations. Did you know that people with big ears have better math abiliies than people with small ears? The reason is that grown ups have bigger ears than kids ... Received on Sun Jan 26 2003 - 00:04:18 CET
