Itakura-Saito nonnegative matrix factorization with group sparsity
We propose an unsupervised inference procedure for audio source separation. Components in nonnegative matrix factorization (NMF) are grouped automatically in audio sources via a p...

Oracle-based checking of untrusted software
We present a variant of Proof-Carrying Code (PCC) in which the trusted inference rules are represented as a higher-order logic program, the proof checker is replaced by a nondeter...
