Robust Local Scoring Function for Text-Independent Speaker Verification
Traditionally, the Universal Background Model (UBM) is viewed as the background model of the entire acoustic feature space. We propose a novel interpretation of the UBM model, and...

Quantization of Sparse Representations
Compressive sensing (CS) is a new signal acquisition technique for sparse and compressible signals. Rather than uniformly sampling the signal, CS computes inner products with rand...

A Fuzzy Vault Scheme
We describe a simple and novel cryptographic construction that we refer to as a fuzzy vault. A player Alice may place a secret value in a fuzzy vault and "lock" it using ...

An MCMC Approach to Lossy Compression of Continuous Sources
Motivated by the Markov chain Monte Carlo (MCMC) relaxation method of Jalali and Weissman, we propose a lossy compression algorithm for continuous amplitude sources that relies on...
