Research activities
Background
- Machine Learning,
- Data Mining,
- Grammatical Inference
studied objects
- Markov chains,
- Hidden Markov Models,
- Multiplicity Automata,
- Weighted Transducer,
- Tree Weighted Automata,
- Tree Edit Distance
main theoretical results
- Multiplicity Automata Algorithm which identifie the class of rational stocastic languages in the limit with probability one,
- The problem to know whether an MA generates a probabilistic distribution is undecidable (was left open in Probabilistic Automata, Azaria Paz, 1977),
- Algorithm of identification in the limit with probability one of some subclass of non deterministic HMM
