Understanding the nuances of rodent social behaviors is critical. The ViT-RSI model demonstrates strong performance across various interactions, though some complex behaviors present unique challenges for automated recognition.
Understanding 'Social Nose Contact' Challenges
Challenge: The 'Social Nose Contact' behavior consistently showed the weakest performance (F1=0.48, AUC=0.66) compared to other behaviors. This is attributed to the limited number of labels for this rare behavior, leading to class imbalance.
Implication: Such events are often brief and visually similar to 'Approaching' or 'Following' behaviors that occur immediately before/after contact. The frame-level classification struggles to capture the temporal transitions crucial for differentiating these nuanced interactions.
Solution Hint: Future work could incorporate temporal modeling or targeted data augmentation for rare behaviors to improve recognition accuracy, crucial for precise scientific insights.
The study utilized the publicly available Rat Social Interaction (RatSI) dataset, comprising 9 videos (15 minutes each at 30 fps) of two rats interacting. The dataset was split into 7 videos for training/validation and 2 for testing, ensuring no cross-video leakage. Input frames were resized to 224x224 and normalized. The model was trained over 50 epochs on an NVIDIA A100 GPU using the TensorFlow framework, with SGD optimizer, weighted cross-entropy loss, and ReduceLROnPlateau for learning rate scheduling. Performance was evaluated using precision, recall, F1 score, and accuracy metrics.
