Abstract

Constructing and simulating artificial neural networks and components thereof within a spreadsheet environment results in user friendly neural networks which do not require algorithmic based software in order to train or operate. Such neural networks can be easily cascaded to form complex neural networks and neural network systems, including neural networks capable of self-organizing so as to self-train within a spreadsheet, neural networks which train simultaneously within a spreadsheet, and neural networks capable of autonomously moving, monitoring, analyzing, and altering data within a spreadsheet. Neural networks can also be cascaded together in self training neural network form to achieve a device prototyping system.

Claims

1. A database scanning pattern recognition device capable of scanning a database for any set of n data values having a predetermined pattern, comprising:

a first neural network including a knowledge domain defined by the predetermined pattern, said first neural network including n inputs and at least one output, said first neural network operable to output a predetermined output in response to a given set of n inputs if said given set of n inputs falls within said knowledge domain thereof,

means for applying a series of sets of n data values from said database to said first neural network as inputs thereto.

2. A database scanning pattern recognition device in accordance with claim 1 wherein said means for applying a series of sets of n data values from said database to said first neural network as inputs thereto includes:

a second neural network for selecting a portion of said database to be scanned, said second neural network comprising an autoassociative neural network including a knowledge domain of various positions within said database,

means associated with said second neural network for obtaining a series of outputs therefrom, each output representative of a database position, and

means for selecting a set of n data values from each of said database positions to be applied as inputs to said first neural network.
