Planar Languages and Learnability

Strings can be mapped into Hilbert spaces using feature maps such as the Parikh map. Languages can then be defined as the preimage of hyperplanes in the feature space, rather than using grammars or automata. These are the planar languages. In this paper we show that using techniques from kernel-based learning, we can represent and efficiently learn, from positive data alone, various linguistica...

On Case-Based Representability and Learnability of Languages

Within the present paper we investigate case-based represen-tability as well as case-based learnability of indexed families of uniformly recursive languages. Since we are mainly interested in case-based learning with respect to an arbitrary xed similarity measure, case-based learnability of an indexed family requires its representability, rst. We show that every indexed family is case-based rep...

On the Regularity and Learnability of Ordered DAG Languages

Order-Preserving DAG Grammars (OPDGs) is a subclass of Hyper-Edge Replacement Grammars that can be parsed in polynomial time. Their associated class of languages is known as Ordered DAG Languages, and the graphs they generate are characterised by being acyclic, rooted, and having a natural order on their nodes. OPDGs are useful in natural-language processing to model abstract meaning representa...

Co-Regular Languages and Uni cation of Co-Regular Languages

The main goal of this work is the investigation of some properties of co-regular languages. In many applications it is important to handle innnite sets of terms. We represent two equivalent formalisms for nite deened innnite sets of term substitutions which are leading to co-regular languages. As it will be proved later the co-regular languages are monoidic homomorphical images of regular langu...
