Greedy Algorithmus: Definition, Vorteile & Nachteile

SOLVED: Stochastic gradient descent (SGD) is simple but widely applicable optimization technique: For " exampl we can use it to train Support Vector Machine: The objective function in this case is given by:J (0)[4 Lossh (y()9 . 26)) Zu01? where Lossh (2) = max0,1 2 is the hinge loss function, (z() with for =1, n are the training examples; with y() e1,-1 being the label for the vector z(i)For simplicity; we ignore the offset parameter B0 in all problems on this page: The stochastic gradient upda
