MAPTRAITS 2014 - The First Audio/Visual Mapping Personality Traits Challenge - An Introduction: Perceived Personality and Social Dimensions.

ABSTRACTThe Audio/Visual Mapping Personality Challenge and Workshop (MAPTRAITS) is a competition event that is organised to facilitate the development of signal processing and machine learning techniques for the automatic analysis of personality traits and social dimensions. MAPTRAITS includes two sub-challenges, the continuous space-time sub-challenge and the quantised space-time sub-challenge. The continuous sub-challenge evaluated how systems predict the variation of perceived personality traits and social dimensions in time, whereas the quantised challenge evaluated the ability of systems to predict the overall perceived traits and dimensions in shorter video clips. To analyse the effect of audio and visual modalities on personality perception, we compared systems under three different settings: visual-only, audio-only and audio-visual. With MAPTRAITS we aimed at improving the knowledge on the automatic analysis of personality traits and social dimensions by producing a benchmarking protocol and encouraging the participation of various research groups from different backgrounds.
