Approximability of Probability Distributions
We consider the question of how well a given distribution can be approximated with probabilistic graphical models. We introduce a new parameter, effective treewidth, that captures...

A Computational Model of Tractable Reasoning - Taking Inspiration from Cognition
Polynomial time complexity is the usual ‘threshold’ for distinguishing the tractable from the intractable and it may seem reasonable to adopt this notion of tractability in th...

Salient Contour Extraction by Temporal Binding in a Cortically-based Network
It has been suggested that long-range intrinsic connections in striate cortex may play a role in contour extraction (Gilbert et al., 1996). A number of recent physiological and ps...

Cell Microscopic Segmentation with Spiking Neuron Networks
Abstract. Spiking Neuron Networks (SNNs) overcome the computational power of neural networks made of thresholds or sigmoidal units. Indeed, SNNs add a new dimension, the temporal a...

Compressive detection for wide-band spectrum sensing
In this paper we propose a novel wide-band spectrum sensing scheme using compressive sensing. The wide-band signal is fed into a number of wide-band filters and the outputs of th...
