Novel VLM Pipeline for Behavioral Annotation
This research introduces a novel vision-language model (VLM) pipeline for classifying mouse behavior directly from video. By leveraging open-source Qwen2.5-VL and innovative prompt engineering, in-context learning (ICL), and frame-level preprocessing, the system achieves high F1 scores across various behaviors, including rare classes like freezing and fleeing. This framework allows for scalable behavioral annotation that can be integrated with neural and experimental datasets.

Improved Accuracy with Pipeline Enhancements
The evaluation demonstrates that incremental additions of prompting, in-context learning (ICL), and frame-wise preprocessing significantly enhance the Qwen2.5-VL model's performance. While prompting alone helps with common behaviors, ICL and frame-level processing are crucial for detecting rare behaviors such as freezing and fleeing, leading to stronger overall F1 scores.

Scalable Behavioral Annotation for Neuroscience
The VLM pipeline enables scalable behavioral annotation of mouse activity, directly from video, producing per-second behavioral vectors. This is critical for integrating with neural datasets (e.g., calcium imaging or Neuropixels) to address complex research questions about fear expression.
- Minimal user input required
- High F1 scores across diverse behaviors
- Addresses limitations of traditional methods like DeepLabCut and MoSeq
Expanding Temporal Context and Integration
Future research will focus on incorporating temporal context into the VLM pipeline, allowing for the analysis of longer video segments and more complex behavioral sequences. This will further enhance the model's ability to understand the nuances of fear expression and other complex behaviors in mice, providing deeper insights for neuroscience research.
