Abstract:In language learning in the limit, the most common type of hypothesis is to give an enumerator for a language. This so-called W -index allows for naming arbitrary computably enumerable languages, with the drawback that even the membership problem is undecidable. In this paper we use a different system which allows for naming arbitrary decidable languages, namely programs for characteristic functions (called C-indices). These indices have the drawback that it is now not decidable whether a given hypothesis is e… Show more
