Iso-array Acceptors and Learning

摘要

The notions of iso-arrays, iso-pictures, local iso-picture languages and recognizable iso-picture languages have been introduced and studied in [6]. In [6] we have provided an algorithm to learn local iso-picture languages through identification in the limit using positive data. In this paper, we construct a two-dimensional on-line tessellation automaton to recognize iso-picture languages and present an algorithm to learn recognizable iso-picture languages from positive data and restricted subset queries.
