Minimum Classification Error - MCE

Concept and definition

Minimum Classification Error - MCE

What is Minimum Classification Error - MCE?

The Minimum Classification Error (MCE) algorithm is a variant of the LVQ method, namely its version LVQ2.1. It tries to ensure the fastest convergence of the solution based on Hebbian learning that updates the winning prototypes by competition.

The difference of the MCE method is that not only the nearest neighbor of each sample in the training set is searched, but also the nearest neighbor with different output and the one with the same output.

In the event that the sample falls within an established window between the two, the one with a different output will be moved away and the one with the same output will be moved closer, in order to improve the classification results.

This is an evolution of the LVQ
