Information about Adaline
ADALINE (Adaptive Linear Neuron or later Adaptive Linear Element) is a single layer neural network. It was developed by Professor Bernard Widrow and his graduate student Ted Hoff at Stanford University in 1960. It is based on the McCulloch-Pitts neuron. It consists of a weight, a bias and a summation function.

Learning inside a single layer ADALINE
Definition
Adaline is a single layer neural network with multiple nodes where each node accepts multiple inputs and generates one output. Given the following variables:- x is the input vector
- w is the weight vector
- n is the number of nodes
some constant
- y is the output
. If we further assume that
Learning Algorithm
Let us assume:
is the learning rate (some constant)
- d is the desired output
- o is the actual output
. The ADALINE converges to the least squares error which is . For a more comprehensive proof, see Adaline (Adaptive Linear)

Traditionally, the term neural network had been used to refer to a network or circuitry of biological neurons. The modern usage of the term often refers to artificial neural networks, which are composed of artificial neurons or nodes.
