Title: Can we trust ChatGPT?

Abstract:

The media has everyone excited about pre-trained large language models (LLMs), such as OpenAI’s ChatGPT and Google’s Bard, which can generate human-like responses to questions and requests for information. This talk will describe the evolution of language modelling over the last 20 years including n-gram models, word-vector models, deep neural networks and the transformer architecture underlying many LLMs. Julie will discuss strengths, weaknesses and pitfalls as well as current research at Sussex evaluating the accuracy of the information in text generated by LLMs such as ChatGPT.
