Fine-grained Emotional Profiling

Human decisions and actions are driven by emotions, more than we realize. Facial expressions reveal many of these emotions. In this talk, I will present the techniques we developed for facial expression analysis. Our main objective is fine-grained detailed emotional profiling in real-world conditions. Contrary to existing approaches, we avoid the classification of emotions into predefined categories and follow a dimensional paradigm. I will highlight different approaches, challenges, and machine-learning techniques to achieve this, including Convolutional Neural Networks. Finally we discuss potential disruptive applications in areas like advertising, HR analytics, crowd analysis, customer satisfaction, and online training.
