PPT-Rosenblatt's Perceptron

Material courtesy of Geoffrey Hinton The history of perceptrons Invented by the psychologist Frank Rosenblatt in 1958 The first successful algorithm for training neurons Still widely used today for tasks with enormous feature vectors that contain many millions of features. 1 MistakeBound Learning Mistakebound learning can be described in terms of playing an in64257nite learning game as follows 1 An adversary chooses some example and shows it to the learner 2 The learner tries to predict the label of the example 3 The The submarine was trapped under the sea powerless after a series of exp lo sions Russian officials claimed that death for the men in the submarine had been instantaneous This proved to be untrue In this essay Roger Rosenblatt considers the final act ICS 61.
