Professor Ted Briscoe: "Large Language Models (like ChatGPT): The Hype and the Reality"
Professor Briscoe Ted's talk focused on how ChatGPT has exposed an unprecedented number of people to cutting-edge natural language processing using large language models. It has also ignited a vigorous and often overblown public debate over the potential benefits, risks and capabilities of Generative AI. In the talk he explained the differences between 'small' and large language models, and showed via examples that, despite their impressive fluency and some 'emergent' capabilities like translation and question answering, they do not as yet fully learn the mapping between form and meaning encoded in the grammar of individual languages, often struggle to resolve pronoun references, and fail to infer the discourse relations between sentences. As such, they represent an impressive and useful step change in language processing capabilities if used with care, but artificial general intelligence remains a challenging and elusive goal that will likely require a significantly different type of model.
Ted has worked on statistical and robust parsing algorithms, computational approaches to lexicon acquisition and to representation of lexical, syntactic and semantic knowledge, textual information extraction from scientific articles and regulatory documents, models of human language learning and processing, and evolutionary models of language development and change. His recent work has mostly focussed on NLP and ML techniques in support of language learning.
