The study of human facial behavior dynamics has shown that apparent personality traits can be reflected through them. To address the limitation of existing methods for personality recognition which only encode short-term facial behaviors in the latent features, a new approach is proposed in this paper for recognizing apparent personality traits. The approach involves training a person-specific network for each subject to model multi-scale long-term person-specific behavior evolution. It is hypothesized that the weights of the network contain person-specific facial behavior-related cues of the subject. These weights are then encoded into a graph representation which serves as the personality representation for the subject and can be processed by standard Graph Neural Networks (GNNs) for personality trait recognition. Experimental results show that this novel network weights-based approach outperforms most traditional latent feature-based approaches and has comparable performance to state-of-the-art methods. Additionally, it produces robust results when using different GNNs and further validates that person-specific networks' weights are correlated to the subject's personality. The proposed method provides a more comprehensive understanding of how facial behaviors reflect apparent personality traits by modeling long-term behavioral evolution and incorporating person-specific cues into the analysis. This approach has significant implications for improving accuracy in personality recognition tasks and could potentially lead to better insights into how human behavior relates to individual differences in personality traits.

Exploring the Relationship between Facial Behavior Dynamics and Apparent Personality Traits

The study of human facial behavior dynamics has revealed that apparent personality traits can be reflected through them. However, existing methods for recognizing these traits often rely on encoding short-term facial behaviors into latent features, which limits their accuracy. To address this limitation, a novel approach is proposed in this paper for recognizing apparent personality traits by training person-specific networks to model multi-scale long-term behavior evolution.

Personality Recognition with Person-Specific Networks

The proposed approach involves training a person-specific network for each subject to capture the individual's long-term behavioral evolution. It is hypothesized that the weights of the network contain person-specific facial behavior cues related to the subject's personality. These weights are then encoded into a graph representation which serves as the personality representation for the subject and can be processed by standard Graph Neural Networks (GNNs) for trait recognition.

Experimental Results

Experimental results show that this novel network weights-based approach outperforms most traditional latent feature based approaches and has comparable performance to state of the art methods. Additionally, it produces robust results when using different GNNs and further validates that person specific networks' weights are correlated to an individual's personality.

Implications of This Approach

The proposed method provides a more comprehensive understanding of how facial behaviors reflect apparent personality traits by modeling long term behavioral evolution and incorporating person specific cues into its analysis.
