TFRBench: A Reasoning Benchmark for Evaluating Forecasting Systems
Summary: arXiv:2604.05364v1 Announce Type: new
In the evolving field of artificial intelligence, the evaluation of forecasting systems has often been limited to numerical accuracy, leaving a substantial gap in understanding their reasoning capabilities. Researchers have now introduced TFRBench, the first benchmark specifically designed to assess the reasoning abilities of forecasting systems. This innovative approach aims to bridge the gap between numerical performance and the interpretability of the forecasting process.
Introduction to TFRBench
TFRBench distinguishes itself from existing benchmarks by focusing on the reasoning generated by forecasting systems. Traditional methods have treated these systems largely as “black boxes,” evaluating their performance solely based on accuracy metrics. However, TFRBench introduces a comprehensive protocol that emphasizes the understanding of cross-channel dependencies, trends, and the influence of external events on forecasting outcomes.
Methodology
The benchmark employs a systematic multi-agent framework that utilizes an iterative verification loop to synthesize numerically grounded reasoning traces. This approach not only enhances the interpretability of forecasting models but also facilitates a deeper analysis of their decision-making processes.
Key Findings
Spanning ten datasets across five distinct domains, the evaluation conducted using TFRBench reveals several critical insights:
- Causal Effectiveness: The reasoning generated by forecasting systems was found to be causally effective, reinforcing its utility for evaluation.
- Improved Forecasting Accuracy: Prompting large language models (LLMs) with the generated reasoning traces significantly enhances forecasting accuracy, with improvements from an average of approximately 40.2% to 56.6%.
- Challenges for Off-the-Shelf LLMs: Benchmarking experiments demonstrated that off-the-shelf LLMs struggle with both reasoning and numerical forecasting, often failing to capture domain-specific dynamics.
Conclusion
TFRBench establishes a new standard for interpretable, reasoning-based evaluation in the realm of time-series forecasting. By focusing on the reasoning capabilities of forecasting systems, TFRBench not only enhances our understanding of these models but also paves the way for more robust and interpretable AI applications in forecasting.
