Contextual Time-Continuous Emotion Recognition Based on Neural Networks

Emotion recognition has been of interest for researchers for a long period of time and during the last two decades it has received a noticeable development due to hardware and software improvements, as well as the increasing demand on intelligent conversational agents. In spite of the fact that modern emotion recognition research aims towards spontaneous data, recorded not in laboratory conditions, and real world applications, it is often being performed in an isolated manner. This implies that the recognition is done without accounting for previous actions or emotional status of a user,  information about his/her interlocutor (if any) and environment while designing the pipeline. All these aspects and sources of information play an important role in defining or affecting the current mood and emotional status of the user; hence they should be analyzed in order to get a precise and comprehensive estimation. My thesis outlines novel approaches to integrate contextual information for improving the performance of automatic emotion recognition systems.
