New method identifies languages from positive data alone, bypassing Gold's theorem

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for identifying languages from positive data alone, overcoming limitations previously established by Gold's theorem. This approach utilizes a contrast operator to generate perturbations of input strings and a contrastive estimation-trained scorer to rank these perturbations. The method achieves PAC conditional identification with sample complexity polynomial in various parameters, offering a novel way to learn language structures without needing negative examples or global normalization constants.

    A Reverse-Gold Theorem: Positive-Data Identification by Substrate-Bounded Contrastive Learners

    Gold's theorem shows that no learner can identify an arbitrary language in a superfinite class from positive presentations alone. We prove a positive result of a different shape. Fix an innate \emph{recursive contrast operator} $R$ mapping any string to a finite set of structural…
