A binary hierarchical classifier is proposed for automatic target recognition. We also require rejection of non-object (non-target) inputs, which are not seen during training or validation, thus producing a very difficult problem. The SVRDM (support vector representation and discrimination machine)

Abstract
Recent studies on automatic new topic identification in Web search engine user sessions demonstrated that learning algorithms such as neural networks and regression have been fairly successful in automatic new topic identification. In this study, we investigate whether another learning algorithm, Support Vector Machines (SVM) are successful in terms of identifying topic shifts and continuations. Sample data logs from the Norwegian search engine FAST (currently owned by Overture) and Excite are used in this study. Findings of this study suggest that support vector machines' performance depends on the characteristics of the dataset it is applied on.
