I'm interested in methods/heuristics for selecting a group
of test variables that have a large/largest value of information.
Most approaches are myopic (i.e., select the variable with maximal
VOI, test its value, select the next one, etc.). I found only two
relevant references: Heckerman et al. 1993 discuss approximate
non-myopic VOI computation, and Madigan and Russell 1995
discuss test selection strategies. Both say that it is a key
capability of an expect system, but surprisintly I could not
find any work beyond this. In particular, I'm happy with the
Heckerman et al. model in which there is a single binary decision
and a single binary chance node affecting the value function.
Can anyone recommend additional useful references?
Thanks,
Ronen
