A self-organizing model for affective memory

Emotions are related to many different parts of our lives: from the perception of the environment around us to different learning processes and natural communication. Therefore, it is very hard to achieve an automatic emotion recognition system which is adaptable enough to be used in real-world scenarios. This paper proposes the use of a growing and self-organizing affective memory architecture to improve the adaptability of the Cross-channel Convolution Neural Network emotion recognition model. The architecture we propose, besides being adaptable to new subjects and scenarios also presents means to perceive and model human behavior in an unsupervised fashion enabling it to deal with never seen emotion expressions. We demonstrate in our experiments that the proposed model is competitive compared with the state-of-the-art approach, and how it can be used in different affective behavior analysis scenarios.
