Suppose w starts off as the zero vector. Then we notice in the general k -way classification problem that we only add or subtract f ( x i) vectors to w .

WebHome University of Washington Department of Statistics WebThe Perceptron Algorithm Frank Rosenblatt suggested this algorithm: Set a threshold value Multiply all inputs with its weights Sum all the results Activate the output 1. Set a threshold value: Threshold = 1.5 2. Multiply all inputs with its weights: x1 * w1 = 1 * 0.7 = 0.7 x2 * w2 = 0 * 0.6 = 0 x3 * w3 = 1 * 0.5 = 0.5 x4 * w4 = 0 * 0.3 = 0
