Representation of structured events and efficient procedures for their recognition

摘要: Abstract Structured events are configurations of objects in logical, spatial, temporal or activity relations. A parameterized structural representation system for this class is discussed. Parameters such representations arbitrarily chosen symbols used to insure consistent references the same object diverse All-or-none matching two basis pattern recognition. In framework, descriptions concept prototypes act as templates stimuli. As a result, recognition can be performed natural and way unaffected by manipulations irrelevant variables. Typical procedures reviewed variety alternative approaches considered light potential combinatorial explosions which might arise applications these procedures. One proposed exploit both redundancy among partially computational parallelism exhaustive search (recognition) problems. Another possibility find special particular For example, accomplish word speech understanding systems, highly practical techniques exist match many parallel (simultaneously) using only simple bit string operations. addition, additional heuristic general use less relational also paper.
