Why do we use the discriminant The discriminant tells us one of two things How many rootsxinterceptszeros does a quadratic function have How many solutions does a quadratic equation have Example. For example a researcher may want to investigate which variables discriminate between f ruits eaten by 1 primates 2 birds or 3 squirrels For that purpose the researcher could collect data on numerous fruit characteristics of those species eaten by e of Computer Science UIUC dengcai2csuiucedu Xiaofei He Yahoo hexyahooinccom Jiawei Han Dept of Computer Science UIUC hanjcsuiucedu Abstract Linear Discriminant Analysis LDA has been a popular method for extracting features which preserve class separa torontoedu Abstract This is a note to explain Fisher linear discriminant analysis 1 Fisher LDA The most famous example of dimensionality reduction is principal components analysis This technique searches for directions in the data that have largest v uiucedu Xiaofei He Yahoo Research Labs hexyahooinccom Kun Zhou Microsoft Research Asia kunzhoumicrosoftcom Jiawei Han Department of Computer Science University of Illinois at Urbana Champaign hanjcsuiucedu Hujun Bao College of Computer Science Zhejia Chye-Hwa Loo and Atef Elsherbeni Center of Applied Electromagnetic Systems Research (CAESR) Electrical Engineering Department The University of Mississippi, University, MS 38677 ABSTRACT The task Given . a quadratic equation use the . discriminant. to determine the nature . of the roots..
