The adaptive linear combiner (ALC) is described, and practical applications of the ALC in signal processing pattern recognition are presented. Six examples given, which system modeling, statistical prediction, noise canceling, echo universe channel equalization. Adaptive using neural nets then discussed. concept involves use an invariance net followed by a trainable classifier.

Translation between semantically equivalent but syntactically different line notations of molecular structures compresses meaningful information into a continuous descriptor.
A pattern recognition concept involving first an 'invariance net' and second a 'trainable classifier' is proposed. The invariance net can be trained or designed to produce set of outputs that are insensitive translation, rotation, scale change, perspective etc., the retinal input pattern. scrambled, however.
