Movie Reconstruction from Brain Signals: "Mind-Reading" - ROOM CHANGED TO Davis Auditorium

Bin Yu

Least Squares, a time-tested method for fitting a linear model to data, attained prominence as far back as 1801 when it was used by Johan Carl Friedrich Gauss to fit astronomical data and predict the trajectory of the newly-discovered asteroid Ceres. Attempts have recently been made to modify the Least Squares method and answer one of the important questions in computational neuroscience: Can the vast quantities of high-dimensional neuroscience data available today be used to decode brain activities?

In a thrilling breakthrough at the intersection of neuroscience and statistics, penalized Least Squares methods have been used to construct a "mind-reading" algorithm that reconstructs movies from fMRI brain signals. The story of this algorithm is a fascinating tale of the interdisciplinary research that led to the development of the system which was selected as one of Time Magazine's 50 Best Inventions of 2011.
