Abstract

The present invention provides a method for class prediction in bioinformatics based on identifying a nonlinear system that has been defined for carrying out a given classification task. Information characteristic of exemplars from the classes to be distinguished is used to create training inputs, and the training outputs are representative of the class distinctions to be made. Nonlinear systems are found to approximate the defined input/output relations, and these nonlinear systems are then used to classify new data samples. In another aspect of the invention, information characteristic of exemplars from one class are used to create a training input and output. A nonlinear system is found to approximate the created input/output relation and thus represent the class, and together with nonlinear systems found to represent the other classes, is used to classify new data samples.

Claims1

Dependent claims

A method of predicting whether an unclassified sample of biological information corresponds to a first class or to a second class, comprising:

(a) selecting a first known sample of biologic information, wherein the first sample corresponds to the first class;
(b) selecting a second known sample of biologic information, wherein the second sample correspond to the second class;
(c) selecting a first representative segment from said first sample;
(d) selecting a second representative segment from said second sample;
(e) combining the first and second representative segments to form a training input;
(f) defining an input/output relationship between the training input and a training output, wherein the training output has a first value over said first representative segment and a second value of said second representative segment;
(g) calculating a non-linear system to approximate the input/output relationship;
and
(h) applying said non-linear system to said unclassified sample to calculate a set of output values.
