Apparatus and method for removing non-discriminating indices of an indexed dataset

PAGE TITLE

Overview

 

PAGE SUMMARY

The present invention is a new method of extracting features from an indexed dataset. The embodiment of the invention consists of two-pass variance analysis before normalization. The first variance analysis removes common characteristics from signal, thus reducing its cardinality and increasing its discriminatory power. The second analysis removes noise from the dataset, again reducing cardinality and increasing discriminatory power. The basic algorithm has been developed and tested on two sets of real data(rat liver polypeptide samples, and human serum polypeptide samples).

 

 APPLICATIONS

TITLE: Applications

 

Classification of single and multi-dimensional indexed data, including but limited to mass spectra and 2-D images, such as those used by genomic pattern recognition systems and proteomic pattern recognition systems

Classification algorithms that detect diseases such as cancer and HIV

Classification algorithms that screen drugs and predict toxicity of unknown compounds

 

ADVANTAGES

TITLE:Advantages

Improves the accuracy of the classification algorithm

Increases the computational speed and reduces requirements on computational machinery performing the classification
