| 课程简介: | Aim is to infer regular grammar from (potentially sparse) sampleof strings：Regular grammar can be represented as a Deterministic Finite Automaton (DFA)； Perceived accuracy of these models has a major impact：Used for empirical comparison with other techniques (publicationsand competitions)，Genetic inference algorithms rely on accuracy as a fitness-function； Conventional accuracy measure is flawed:：Test set is usually a random sample → non-uniform coverage，Single value provides no insight into the strenghts/weaknesses ofthe technique. |
