We consider a hierarchical two-layer model of natural signals in which both layers are learned from the data. Estimation is accomplished by Score Matching, a recently proposed est...
This paper investigates the behaviors and the properties of a "Give and Take" cellular automaton on a graph. Using an economical metaphor, this model implements the excha...
In a probabilistic cellular automaton (PCA), the cells are updated synchronously and independently, according to a distribution depending on a finite neighborhood. A PCA can be vi...
Flash is a widely used storage device that provides high density and low power, appealing properties for general purpose computing. Today, its usual application is in portable spe...
VLSI placement tools usually work in two steps: First, the cells that have to be placed are roughly spread out over the chip area ignoring disjointness (global placement). Then, i...
