How do I train and classify expression using Fuzzy Rule Interpolation.

I am new in computer vision and to Matlab. But, I have been able to upload images, detect the image using Viola Jones Algorithm and extract the features using Local Binary Pattern. But will like to classify the expression with Fuzzy Rule Interpolation.

I have some images with the emotion labels, FACS labels and Landmark which I got from the Cohn Kanade (CK+) database. from which I believe that the images are already trained. But will still need to learn how to train and classify these images with Fuzzy Rule Interpolation.

Any useful information is welcomed.
