Where I can I find Pre Trained CNN Datasets for Facial Emotion Recognition?
You are probably interested in IAPS, and want to read Analysis of Physiological Signals for Emotion Recognition Based on Support Vector Machine.

But to be honest this classification is doomed in advance, not only pictures are stripped of below threshold of effector activisation but also you do not get baseline as point of reference.

If you are really interested then start from reading everything that Ekman or Sejnowski wrote and feed your NN with only relevant parts, otherwise the most of the data feeded is noise.
