    Noise-Contrastive Estimation of Unnormalized Statistical Models, with Applications to Natural Image Statistics
    Download  www.cs.helsinki.fi
    We consider the task of estimating, from observed data, a probabilistic model that is parameterized by a finite number of parameters. In particular, we are considering the situat...

    Max-Margin Min-Entropy Models
    Download  jmlr.csail.mit.edu
    We propose a new family of latent variable models called max-margin min-entropy (m3e) models, which define a distribution over the output and the hidden variables conditioned on ...

    Bayesian regularization of non-homogeneous dynamic Bayesian networks by globally coupling interaction parameters
    Download  jmlr.csail.mit.edu
    To relax the homogeneity assumption of classical dynamic Bayesian networks (DBNs), various recent studies have combined DBNs with multiple changepoint processes. The underlying as...

    Universal Measurement Bounds for Structured Sparse Signal Recovery
    Download  homepages.cae.wisc.edu
    Standard compressive sensing results state that to exactly recover an s sparse signal in Rp , one requires O(s · log p) measurements. While this bound is extremely useful in prac...
