A Capacity Scaling Law for Artificial Neural Networks

Seminar: Redwood Seminar | September 6 | 12-1 p.m. | 560 Evans Hall

Gerald Friedland, UC Berkeley

Neuroscience Institute, Helen Wills

In this talk, we derive the calculation of two critical numbers that quantify the capabilities of artificial neural networks with gating functions, such as sign, sigmoid, or rectified linear units. First, we derive the calculation of the upper limit Vapnik-Chervonenkis dimension of a network with binary output layer, which is the theoretical limit for perfect fitting of the training data. Second,...   More >

fMRI at high magnetic fields: Spatial resolution limits and applications

Seminar: Neuroscience Seminar | September 6 | 4-5:30 p.m. | 5101 Tolman Hall

Essa Yacoub, University of Minnesota

Neuroscience Institute, Helen Wills

While higher magnetic fields present the opportunity to address higher resolution neuroscience questions, such applications are faced with confounds of fMRI spatial specificity, as well as technical challenges in acquiring higher resolution images. Significant efforts have been put forth over the past 20 years towards understanding these issues and in addressing them with technical developments....   More >
