Erratum: Learning without Coding

Abstract

Our ALT'2010 paper claimed that every computably finitely thick [LZ96, Definition 9] class of languages can be identified by enumeration operator [MZ10, Definition 1(e) and Theorem 12]. However, this is, in fact, false. We intend to include a proof of the claim's negation in the journal version of our paper, which has been submitted. Acknowledgements.We would like to thank Sanjay Jain for noticing our error, and for providing us a proof of the claim's negation.
