The perceptron is a kind of binary classifier that maps its input (a real-valued vector in the simplest case) to an output value calculated as. Novikoff, A.

У машинском учењу, перцептрон је алгоритам за надгледано учење бинарних класификатора.Бинарни класификатор је функција која може одлучити да ли улаз, представљен вектором бројева, припада некој одређеној класи. Novikoff, A. Who gave permission to use perceptrons … The perceptron convergence theorem proof states that when the network did not get an example right, its weights are going to be updated in such a way that the classifier boundary gets closer to be parallel to an hypothetical boundary that separates the two classes. 1 Perceptron The Perceptron, introduced by Rosenblatt [2] over half a century ago, may be construed as a parameterised function, which takes a real-valued vector as input, and produces a Boolean output. 0000063827 00000 n In Proceedings of the Symposium on the Mathematical Theory of Automata, 1962. imported ; Cite this publication.

The idea of the proof is that the weight vector is always adjusted by a bounded amount in a direction with which it has a negative dot product , and thus can be bounded above by O ( √ t ) , where t is the number of changes to the weight vector.
