PATRA: Pattern-Aware Alignment and Balanced Reasoning for Time Series Question Answering

Bin Yang, Chenjuan Guo, Christian S. Jensen, Junkai Lu, Peng Chen, Xingjian Wu, Yang Shu

PATRA improves time series question answering by aligning extracted trends and seasonalities with language models while balancing rewards across task difficulties to support deeper reasoning.

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

PATRA outperforms strong baselines across diverse Time Series Question Answering (TSQA) tasks, demonstrating superior cross-modal understanding and reasoning capability.

C2weakest assumption

That the pattern-aware mechanism successfully captures relevant dynamics without introducing noise and that the balanced reward truly enables deeper reasoning rather than just averaging performance across tasks.

C3one line summary

PATRA improves time series question answering by extracting patterns like trends and seasonalities for alignment and applying a task-aware balanced reward to support coherent reasoning.
