Convex Approaches to Model Wavelet Sparsity Patterns
Statistical dependencies among wavelet coefï¬cients are commonly represented by graphical models such as hidden Markov trees (HMTs). However, in linear inverse problems such as d...

A Probabilistic Interaction Model for Multipitch Tracking With Factorial Hidden Markov Models
—We present a simple and efï¬cient feature modeling approach for tracking the pitch of two simultaneously active speakers. We model the spectrogram features of single speakers u...

Common-Frame Model for Object Recognition
A generative probabilistic model for objects in images is presented. An object consists of a constellation of features. Feature appearance and pose are modeled probabilistically. ...

Management of probabilistic data: foundations and challenges
Many applications today need to manage large data sets with uncertainties. In this paper we describe the foundations of managing data where the uncertainties are quantified as pro...
