Title: Support Vector Machine based Exploratory Projection Pursuit Optimization for User face identiﬁcation
Speaker: Souad Larabi Mariesainte , PhD| Information Technology Department, CCIS, KSU.
For most real-world biometric identification applications, the training database size could be very large, i.e. in the range of several thousands. This yields to the curse of dimensionality problem. The downside of such a problem is that it could negatively affect both the identification performance and speed. In this research study we used Projection Pursuit (PP) methods to determine clusters of users having significant similarities and then applied Support Vector Machine (SVM) classifiers on each cluster of users independently. Experimental results obtained using YALE face database showed that the proposed method allowed reducing the dimensionality of the dataset for training SVMs and thus improving the performance and speed of biometrics based user identification systems. Further improvement can be achieved when using within-between projection pursuit index with PP and also when using hierarchical clustering based PP.
