Extending Distributional Learning from Positive Data and Membership Queries
Proceedings of 16th edition of the International Conference on Grammatical Inference, PMLR 217:8-22, 2023.
Abstract
We consider an extension of distributional learning of context-free languages (from positive data and membership queries), where nonterminals are represented by extended regular expressions (allowing all Boolean operations) augmented by atoms corresponding to membership queries. These nonterminals classify a string based not just on its distribution, but also on the distributions of its substrings. The learning algorithm for this extension works in essentially the same way as in previous works on distributional learning, while targeting a significantly larger class of context-free languages.
