... Discriminative Language Model with Pseudo-Negative samples We propose a novel discriminative language model; a Discriminative Language Model with Pseudo-Negative samples (DLM-PN). In this model, pseudo-negative ... dis-criminative language models can achievemore accurate discrimination because theycan employ overlapping features and non-local information. However, discriminative language models have been used ... andnot all relevant features can be included. A discriminative language model (DLM) assigns a scoreto a sentence , measuring the correct-ness of a sentence in terms of grammar and prag-matics,...
