Noisy K Best-Paths for Approximate Dynamic Programming with Application to Portfolio Optimization
Abstract— We describe a general method to transform a non-Markovian sequential decision problem into a supervised learning problem using a K-bestpaths algorithm. We consider an a...

Markov Random Field Modeling in Median Pyramidal Transform Domain for Denoising Applications
We consider a median pyramidal transform for denoising applications. Traditional techniques of pyramidal denoising are similar to those in wavelet-based methods. In order to remove...

On a Theory of Media Processing Systems Behavior, with Applications
In this article we provide a model for the dynamic behavior of media processing chains of tasks communicating via bounded buffers. The aim is to find the overall behavior of a cha...
