This is a generic class for artificial intelligence type computers and digital data processing systems and corresponding data processing methods and products for emulation of intelligence (i.e., knowledge based systems, reasoning systems, and knowledge acquisition systems); and including systems for reasoning with uncertainty (e.g., fuzzy logic systems), adaptive systems, machine learning systems, and artificial neural networks.

Subclass 40: Radiant energy neural network

Class 708: Electrical Computers: Arithmetic Processing And Calculating

This is the generic class for electrical apparatus and corresponding methods for performing calculation operations. There are three main divisions: 1. electrical hybrid calculating computers; 2. electrical digital calculating computers; 3. electrical analog calculating computers.
