What is the name for this classification algorithm?

Can you help me find the name of this classification method:



Assume we have the following data: $n$ dimensional feature vectors we want to classify in two classes.




  1. We model the classes as two $n$ dimensional gaussian distributions estimated from the data.

  2. We classify a new vector to the class that maximizes the PDF (probbility density function) at that point.

Probably Quadratic Discriminant Analysis.



There are also names for different constraints you could make:




  1. Covariance matrices of both classes are equal - Linear Discriminant Analysis.


  2. Only diagonal elements of the covariance matrix are non-zero - Naive Bayes Classifier


  3. Covariance matrix is identity (diagonals = 1, non-diagonals = 0) - Nearest Centroid Classifier
