Summary

A new Global Cross-Cultural Facial Expression Recognition (GCC-FER) dataset and a Culture-Aware FER (CA-FER) system are introduced to address cultural biases in dynamic facial expression recognition (DFER). The GCC-FER dataset comprises 23,934 video samples across four cultural groups (African, Caucasian, East Asian, South Asian) and seven basic expressions, curated using a hybrid strategy to include underrepresented populations. This dataset is the first large-scale global cross-cultural DFER benchmark. The proposed CA-FER system mitigates cultural bias by adaptively recalibrating latent facial representations using behaviorally grounded cultural priors derived from Action Unit (AU) activation patterns. Experiments on GCC-FER showed CA-FER achieved 61.70% Unweighted Average Recall (UAR) and 64.80% Weighted Average Recall (WAR), a +7.50 percentage point UAR improvement over the culture-agnostic ViViT baseline. On the DFEW benchmark, CA-FER achieved 63.93% UAR, outperforming the DPCNet by +6.82 percentage points without extensive pre-training.

Key takeaway

For machine learning engineers developing facial expression recognition systems, you should integrate culturally diverse datasets and adaptation mechanisms. Ignoring cultural variability limits model robustness in real-world deployments. Consider using behaviorally grounded cultural priors, like those derived from Action Units, to adapt latent representations. This approach significantly improves DFER performance across multicultural settings, even without large-scale pre-training, enhancing generalization for your models.

Key insights

Cultural nuances significantly impact DFER performance, necessitating culture-aware models and diverse datasets.

Principles

• Facial expressions vary systematically across cultures.
• Dataset diversity is crucial for robust FER models.
• Behaviorally grounded priors mitigate cultural bias.

Method

The CA-FER system derives culture-specific behavioral priors from Action Unit (AU) activation patterns, then adaptively recalibrates latent spatio-temporal facial representations using these priors for expression classification.

In practice

• Curate datasets with diverse cultural representation.
• Incorporate AU-based cultural priors into DFER models.
• Evaluate DFER systems using Unweighted Average Recall (UAR).
