RÉSUMÉ

Large language models show intriguing emergent behaviors, yet they receive at least three to four — and sometimes as much as six — orders of magnitude more language data than human children. What accounts for this vast difference in sample efficiency? I will describe steps towards a paradigm in which we can address this question. In particular, I'll discuss the use of egocentric video ("baby headcam") data for model training, and the use of developmental data for model evaluation. This paradigm provides a model-based framework for exploring the nature of children's early development.

BIOGRAPHIE

Michael C. FRANK is Benjamin Scott Crocker Professor of Human Biology in the Department of Psychology at Stanford University and Director of the Symbolic Systems Program. He studies children's language learning and development, with a focus on the use of large-scale datasets to understand the variability and consistency of learning across cultures. He is a founder of the ManyBabies Consortium, and has led open-data projects including Wordbank and the ongoing LEVANTE project.
