Higher-order statistics-based nonlinear speech analysis (2002)
Journal Article
Soraghan, J. J., Hussain, A., Alkulabi, A., & Durrani, T. (2002). Higher-order statistics-based nonlinear speech analysis. Control and Intelligent Systems, 30, 11-18

A fast and robust three-level binary higher order statistics (HOS) based algorithm for simultaneous voiced/unvoiced detection and pitch estimation of speech signals in coloured noise environments with low SNR is presented. The use of the three-level... Read More about Higher-order statistics-based nonlinear speech analysis.

Stochastic resonance and finite resolution in a network of leaky integrate-and-fire neurons (2002)
Presentation / Conference Contribution
Mtetwa, N., Smith, L., & Hussain, A. (2002). Stochastic resonance and finite resolution in a network of leaky integrate-and-fire neurons. In Artificial Neural Networks — ICANN 2002 (117-122). https://doi.org/10.1007/3-540-46084-5_20

This paper discusses the effect of stochastic resonance in a network of leaky integrate-and-fire (LIF) neurons and investigates its realisation on a Field Programmable Gate Array (FPGA). We report in this study that stochastic resonance which is main... Read More about Stochastic resonance and finite resolution in a network of leaky integrate-and-fire neurons.

A new neural network and pole placement based adaptive composite controller (2002)
Presentation / Conference Contribution
Hussain, A., Zayed, A. S., & Smith, L. (2001, December). A new neural network and pole placement based adaptive composite controller. Presented at Multi Topic, IEEE International Conference, Lahore, Pakistan

The paper describes a new composite control method combining a neural network estimator with a conventional pole-placement based adaptive controller. The neural network estimation technique presented by Hussain (2000) is particularly effective when t... Read More about A new neural network and pole placement based adaptive composite controller.
