A recurrent multiscale architecture for long-term memory prediction task (2003)
Presentation / Conference Contribution
Squartini, S., Hussain, A., & Piazza, F. (2003, April). A recurrent multiscale architecture for long-term memory prediction task. Presented at 2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., Hong Kong, China

In the past few years, researchers have been extensively studying the application of recurrent neural networks (RNNs) to solving tasks where detection of long term dependencies is required. This paper proposes an original architecture termed the Recu... Read More about A recurrent multiscale architecture for long-term memory prediction task.

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.

A modified generalised minimum-variance stochastic self-tuning controller with pole-zero placement (2001)
Presentation / Conference Contribution
Zayed, A., Hussain, A., & Smith, L. (2001, December). A modified generalised minimum-variance stochastic self-tuning controller with pole-zero placement. Presented at IEEE International Multi Topic Conference, 2001, Lahore, Pakistan

The paper proposes a modified robust self-tuning controller, which minimises a cost function, incorporating system input, system output and set-point. It provides an adaptive mechanism which ensures that both the closed-loop poles and zeros are place...
