Talk : Dimension reduction techniques in object recognition tasks

Dimension reduction (DR) is one of the core components in pattern recognition and machine learning. In general, the motivation of DR is to: reduce the dimensionality of feature space, speed up and reduce the cost of a learning algorithm, improve the predictive accuracy of a classification algorithm, and to improve the visualization and the comprehensibility of the induced concepts. In this tutorial, we shall: (1) focus on linear and non-linear feature extraction techniques. (2) see how feature extraction can be perceived as a constraint or unconstraint optimization problem. (3) investigate their roles in information extraction, low-dimension structure preservation and object recognition tasks.
