### **[AAAI 2026] Facial-R1: Aligning Reasoning and Recognition for Facial Emotion Analysis**

**Dataset Summary**

FEA-20K is a large-scale, fine-grained dataset for Facial Emotion Analysis (FEA), containing approximately 20,000 samples. It was created using the novel **Facial-R1** framework, a three-stage training process designed to align reasoning and recognition in Vision-Language Models.

The dataset is built to support explainable AI by breaking down emotion analysis into three distinct but interrelated sub-tasks. It was generated with a low-cost iterative process, starting from only 300 high-quality seed samples and using reinforcement learning to synthesize a large, high-quality corpus.

**Supported Tasks**

The dataset is designed to benchmark models on three core tasks:

*   **Facial Emotion Recognition**: Classifying the primary emotion of a facial image (e.g., "disgust", "happiness").
*   **Facial Action Unit (AU) Recognition**: Detecting the presence of specific facial muscle movements (e.g., AU4: brow lowerer).
*   **AU-based Emotion Reasoning**: Generating natural language explanations that link the detected AUs to the final emotion prediction, explaining *why* a certain emotion was recognized.

**Dataset Structure**

*   **Total Samples**: ~20,000
*   **Training Set**: 17,737 samples automatically constructed via the Facial-R1 synthesis strategy.
*   **Test Set**: 1,688 high-quality samples that have been manually verified for accuracy.
