Empowering VLMs for Few-Shot Multimodal Time Series Classification via Tailored Agentic Reasoning

Boxin Li, Dan Li, Erli Meng, Jian Lou, Jiawei Huang, Lin Li, Qihao Quan, See-kiong Ng, Wenjie Feng, Xiao Zhang

A three-role agentic framework with a self-evolving knowledge bank raises VLM accuracy on few-shot multimodal time series classification while generating human-readable feature explanations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

MarsTSC delivers substantial and consistent performance gains across 6 VLM backbones, outperforming both classical and foundation model-based time series baselines under few-shot conditions, while producing interpretable rationales that ground each classification decision in human-readable feature evidence.

C2weakest assumption

That the Reflector can reliably identify and the Modifier can safely incorporate temporal features overlooked by the Generator without introducing new biases or causing the knowledge bank to collapse or overfit during iterative refinement and test-time updates.

C3one line summary

MarsTSC is a VLM-based agentic reasoning framework with a self-evolving knowledge bank and Generator-Reflector-Modifier roles that achieves better few-shot multimodal time series classification than baselines on 12 benchmarks.
