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 ÐÔ°®ÊÓƵ evaluating the accuracy of the information in text generated by LLMs such as ChatGPT.
