摘要

Learning-oriented emotions have not been studied by emotion recognition systems. These emotions have not been taken into account by other studies despite their importance in educational context. This work presents a recognition system which uses deep learning approach using convolutional neural network for solving that problem. A convolutional architecture was designed and tested with 3 different facial expression databases. The architecture is composed of 3 convolutional layers, 3 max-pooling layers, and 3 deep neural networks. The first database contains facial images on 6 basic emotions; the second and third databases contain images of learning-centered facial expressions. The tests show a 95% in the basic emotion database, a 97% for the first learning-centered emotion database and a 75% for the third database. We discuss about the differences in results among the three emotion databases.
