A Multi-Channel Temporal Attention Convolutional Neural Network Model for Environmental Sound Classification

ICASSP 2021accepted

Recently, many attention-based deep neural networks have emerged and achieved state-of-the-art performance in environmental sound classification. The essence of attention mechanism is assigning contribution weights on different parts of features, namely channels, spectral or spatial contents, and te…

A Study of Training Targets for Deep Neural Network-Based Speech Enhancement Using Noise Prediction

ICASSP 2018accepted

Several architectures have been proposed for deep neural network (DNN)-based speech enhancement; however, these all utilize training targets related to the clean speech signal. In this paper, we evaluate the performance of several training targets in a noise-prediction DNN framework and compare the…

Using Block Coordinate Descent to Learn Sparse Coding Dictionaries with a Matrix Norm Update

ICASSP 2018accepted

Researchers have recently examined a modified approach to sparse coding that encourages dictionaries to learn anomalous features. This is done by incorporating the matrix I-norm, or l1,∞ mixed matrix norm, into the dictionary update portion of a sparse coding algorithm. However, solving a matrix nor…
