linear discriminant analysis

Terms from Artificial Intelligence: humans at the heart of algorithms

The glossary is being gradually proof checked, but currently has many typos and misspellings.

Linear discriminant analysis attempts to create one or more linear functions to separate known classes. In the case of two classes and 2D data this is simply a line that runs between the classes. Ideally the classes are completely separated by the linear functions, but in some case this may be impossible, either because of noise blurring the boundaries (in which case the linear discrimant may still be a good classifier), or because the classes are not linearly separable.
