A Multiple Instance Learning Approach for Content Based Image Retrieval …

WebIt can be seen as a (1+x)-class learning problem: There are an unknown number (x) of classes, but the user is interested in one class, i.e. the user is biased toward one class. Similarly: in content-based image retrieval, and document retrieval in general. How do we approach this problem then? It is reasonable to assume that positive examples WebIn this paper, we introduce a one-class support vector machine (SVM) method to predict miRNA hair-pins among the hairpin structures.
