AI@Melbourne Colloquium Series: Benign Overfitting with Peter Bartlett

Deep learning has revealed some major surprises from the perspective of statistical complexity: even without any explicit effort to control model complexity, these methods find prediction rules that give a near-perfect fit to noisy training data and yet exhibit excellent prediction performance in practice. This talk reviews recent work on methods that predict accurately in probabilistic settings despite fitting too well to training data. We see how benign overfitting can occur with sufficient overparameterization in regression and classification problems, but it leads to sensitivity to adversarial examples.

This is the AI@Melbourne Colloquium Series, a program of talks on the future of Artificial Intelligence at The University of Melbourne.

Stay and enjoy complimentary afternoon tea and networking following the event.
