A Probabilistic Analysis of Marker-Passing Techniques for Plan Recognition
Glenn Carroll and Eugene Charniak
June 1991
Abstract:
Useless paths are a chronic problem for marker-passing techniques. We use a probabilistic analysis to justify a method for quickly identifying and rejecting useless paths. Using the same analysis, we identify key conditions and assumptions necessary for marker passing to perform well.(complete text in pdf or gzipped postscript)
