classifier processor

Post by yannick »

Hi,

I would like to know if i can add a third label in this module.
Because i would like to do a classification between 3 class left,right and up. Can you say me if it possible with the classification processor.

Thanks

Hi yannick

The classifier processor relies on a given classifier configuration, generated by a classifier trainer.
In order to have a 3-class classifier, you must use a classifier trainer with a 3-class algorithm.

OpenViBE is given with the LDA algorithm, which is a 2-class classifier. If you need more classes, you will have to implement a new classifier algorithm (k nearest neighbors for example), and use it in the classifier trainer.

hope this helps,

Laurent
