A Robust, Real-Time Voice Activity Detection Algorithm for Embedded Mobile Devices
When an Automatic Speech Recognition (ASR) system is applied in noisy environments, Voice Activity Detection (VAD) is crucial to the performance of the overall system. The employment of the VAD for ASR on embe...

A Matrix-Oriented Method for Appearance-Based Data Compression – An Idea from Group Representation Theory
Motivated by ideas of group representation theory, we propose a matrix-oriented method to dimension reduction for image data. By virtue of the action of Stiefel manifold, the original image representations can...
