## What is Linear Discriminant Analysis (LDA)?

Discriminant analysis is a statistical technique to classify objects into mutually exclusive and exhaustive groups based on a set of measurable object's features. Term discriminant analysis comes with many different names for difference field of study. It is also often called
*
pattern recognition
*
,
*
supervised learning
*
, or
*
supervised classification
*
. This tutorial gives overview about Linear Discriminant Analysis (LDA). If the number of classes is more than two, it is also sometimes called Multiple Discriminant Analysis (MDA).
