Towards multi-speaker unsupervised speech pattern discovery
In this paper, we explore the use of a Gaussian posteriorgram based representation for unsupervised discovery of speech patterns. Compared with our previous work, the new approach...

Waves, bumps, and patterns in neural field theories
Neural field models of firing rate activity have had a major impact in helping to develop an understanding of the dynamics seen in brain slice preparations. These models typically...

Rewriting Queries Using Views with Access Patterns Under Integrity Constraints
We study the problem of rewriting queries using views in the presence of access patterns, integrity constraints, disjunction, and negation. We provide asymptotically optimal algori...

A hybrid dynamic/quadratic programming algorithm for interconnect tree optimization
In this paper, we present an algorithm for delay minimization of interconnect trees by simultaneous buffer insertion/sizing and wire sizing. The algorithm integrates the quadratic...
