Adaline
摘要
The simplest and most widely used learning algorithm is the least mean square (LMS) algorithm. This algorithm was used to train ADALINE (adaptive linear neuron). ADALINE was a single trainable neuron. Input training patterns were presented, and the weights (coefficients) were adjusted to deliver neuron outputs that are the best least square fit to the desired outputs of the training patterns. LMS is based on the method of steepest descent. ADALINE is the basic building block of present-day neural networks.
