We present a theoretical study of free non-Euclidean plates with a disc geometry and a prescribed metric that corresponds to a constant negative Gaussian curvature. We take the equilibrium configuration taken by the these sheets to be a minimum of a Foppl Von-Kà rmà n type functional in which configurations free of in plane stretching correspond...

The spiking dynamics of simultaneously recorded neurons from a small region of cortex reflect the local network structure of excitatory and inhibitory connections between observed neurons, as well as the time varying response of the neurons to their many unobserved and correlated inputs. Inference about the local network is easily contaminated b...

Learning high-dimensional probability distributions with a veryreduced number of samples is no more difficult than with a greatmany. However, arranging for such models to generalize well in thesmall-sample domain is hard. Our approach is motivated bycompositional models and Bayesian networks, and designed to adapt tosample size. We start with a ...

This talk is about research in scene interpretation. Most algorithmsfor detecting and describing instances from object categories consistof looping over a partition of a 'pose space' with dedicated binaryclassifiers. This strategy is inefficient for a complex pose:fragmenting the training data severely reduces accuracy, and thecomputational cost...
