WebWe consider the problem of projecting a vector on the intersection of a hyperplane and a box in Rn. This paper extends a previous result of Maculan, Minoux, and Plateau (Ref. 1) concerning the projection of a vector on the intersection of a hyperplane and Rn+. We present an O(n) time algorithm based on the linear-time median-finding algorithm. WebIt is a discriminative classifier formally defined by separating hyperplane. In other words, given the labeled training sample, the algorithm outputs an optimal hyperplane score that categorizes new testing ... The gained optimized hyperparameter score and their best CV score are shown in FIG. 10. FIG. 11 represents the graph of the ...
