Research
Temporal Contrastive Learning for Interpretable Facial Emotion Recognition
B.S. thesis. Two-stage approach: NT-Xent temporal contrastive pretraining over short- and long-range views of 38-dimensional OpenFace features, then a four-layer Transformer encoder with attention-based temporal aggregation.
