PAC-Learnability of Probabilistic Deterministic Finite State Automata in Terms of Variation Distance
14 years 4 months ago
We consider the problem of PAC-learning distributions over strings, represented by probabilistic deterministic finite automata (PDFAs). PDFAs are a probabilistic model for the gen...
