Widrow and Hoff were not primarily concerned with understanding the organization and function of the human mind.
Figure 2 summarizes such difference schematically.įrom a cognitive science perspective, the main contribution of the ADALINE was methodological rather than theoretical. This means that the learning procedure is based on the outcome of a linear function rather than on the outcome of a threshold function as in the perceptron. The main difference between the perceptron and the ADALINE is that the later works by minimizing the mean squared error of the predictions of a linear function. At the time, implementing an algorithm in a mainframe computer was slow and expensive, so they decided to build a small electronic device capable of being trained by the ADALINE algorithm to learn to classify patterns of inputs. Widrow and Hoff came up with the ADALINE idea on a Friday during their first session working together. When Widrow moved from MIT to Stanford, a colleague asked him whether he would be interested in taking Ted Hoff as his doctoral student. Widrow and Hoff were electrical engineers, yet Widrow had attended the famous Dartmouth workshop on artificial intelligence in 1956, an experience that got him interested in the idea of building brain-like artificial learning systems.
The ADALINE ( Adaptive Linear Neuron) was introduced in 1959, shortly after Rosenblatt’s perceptron, by Bernard Widrow and Ted Hoff (one of the inventors of the microprocessor) at Stanford. Determine what kind of problems can and can’t be solved with the ADALINE.
