Frank Rosenblatt multilayer perceptron extreme learning machine
Charles Tappert writes that Frank Rosenblatt developed and explored all of the basic ingredients of the deep learning systems of today, referring to Rosenblatt's 1962 book which introduced a multilayer perceptron (MLP) with 3 layers: an input layer, a hidden layer with randomized weights that did not learn, and an output layer. However, since only the output layer had learning connections, this was not yet deep learning. It was what later was called an extreme learning machine.
