Grammar of the Wave: Towards Explainable Multivariate Time Series Event Detection via Neuro-Symbolic VLM Agents
TL;DR
Time Series Event Detection (TSED) struggles with the lack of labeled data for identifying meaningful events in multivariate time series. To tackle this, the authors developed the Event Logic Tree (ELT) framework and the SELA neuro-symbolic VLM agent, which uses textual event descriptions to ground events in signal data.
✦ Why It Matters
Engineers can leverage SELA for more efficient event detection in time series data with minimal labeled examples.
Key Takeaways
- Utilize SELA for event detection in multivariate time series data.
- Leverage minimal labeled data by using textual event descriptions.
- Implement Event Logic Tree for structured temporal logic representation.
- Achieve explainable AI outcomes with tree-structured explanations.
How It Works
SELA operates by first interpreting natural language event descriptions through the Event Logic Tree (ELT), which structures these descriptions into a logical framework. The model then analyzes multivariate signals, grounding signal primitives iteratively based on visualizations.
This process allows SELA to identify relevant event intervals while adhering to the constraints set by the ELT, ensuring that the results are both accurate and interpretable.
