A Partially Collapsed Gibbs Sampler for Unsupervised Nonnegative Sparse Signal Restoration
ICASSP 2021accepted
In this paper the problem of restoration of unsupervised nonnegative sparse signals is addressed in the Bayesian framework. We introduce a new probabilistic hierarchical prior, based on the Generalized Hyperbolic (GH) distribution, which explicitly accounts for sparsity. On the one hand, this new pr…
