About

Alona Fyshe is a Fellow in CIFAR’s Learning in Machines & Brains program, a CIFAR Azrieli Global Scholar 2016-2018, and Canada CIFAR AI Chair at Amii. She is  an assistant professor.at the University of Alberta.

Fyshe is a computer scientist by training, but her research straddles multiple areas including neuroscience, machine learning, and computational linguistics. Her lab explores how the human brain processes and represents language meaning (semantics) and how it combines words to make complex meaning (semantic composition). Traditionally, models of semantics have been based on large text datasets. These are useful to a point, but to build complete semantic models we need to incorporate experiential knowledge. One way to do this is to study semantics ‘in vivo,’ using brain imaging technology such as fMRI and EEG.

Currently, brain image datasets are very small, representing about an hour of acquisition time per participant. Fyshe proposes moving brain imaging to ‘the field’ – having people record their own brain images, using consumer-grade EEG systems deployed in the home. This will produce much larger datasets, allowing her to more fully explore the complexities of language.
