Extending Boosting for Large Scale Spoken Language Understanding
We propose three methods for extending the Boosting family of classifiers motivated by the real-life problems we have encountered. Our results indicate that it is possible to obtain the same…

Pose-Encoded Spherical Harmonics for Face Recognition and Synthesis Using a Single Image
In this paper, we propose to address one of the most challenging scenarios in face recognition. That is, to identify a subject from a test image that is acquired under…

Speaker Recognition with Session Variability Normalization Based on MLLR Adaptation Transforms
We present a new modeling approach for speaker recognition that uses the maximum-likelihood linear regression (MLLR) adaptation transforms employed by a speech recognition system as features for support vector machine…
