A novel psychoacoustically motivated multichannel speech enhancement system (2007)
Presentation / Conference Contribution
Hussain, A., Cifani, S., Squartini, S., Piazza, F., & Durrani, T. (2007, March). A novel psychoacoustically motivated multichannel speech enhancement system. Presented at COST Action 2102 International Workshop, Vietri sul Mare, Italy

The ubiquitous noise reduction / speech enhancement problem has gained an increasing interest in recent years. This is due both to progress made by microphone-array systems and to the successful introduction of perceptual models. In the last decade,...

Using biclustering for automatic attribute selection to enhance global visualization (2007)
Presentation / Conference Contribution
Abdullah, A., & Hussain, A. (2006, April). Using biclustering for automatic attribute selection to enhance global visualization. Presented at Visual Information Expert Workshop, VIEW 2006, Paris, France

Data mining involves useful knowledge discovery using a data matrix consisting of records and attributes or variables. Not all the attributes may be useful in knowledge discovery, as some of them may be redundant, irrelevant, noisy or even opposing....
