TRACE: A Temporal Conditional Estimation for Multimodal Time Series Foundation Models

TRACE is a new conditional estimation framework for multimodal time series foundation models that handles temporal misalignment and missing data across different modalities. By inferring incomplete modalities from available data sources, TRACE outperforms existing approaches on healthcare and sentiment analysis benchmarks, demonstrating robust cross-modal representation learning.

Beyond Accuracy: Are Time Series Foundation Models Well-Calibrated?

Researchers evaluated the calibration properties of five recent time series foundation models and found they maintain better confidence alignment than traditional deep learning approaches. Unlike typical neural networks that exhibit overconfidence, these foundation models demonstrate reliable uncertainty quantification across various forecasting scenarios, which is critical for real-world deployment in financial and operational decision-making.

TSFMAudit: Data Contamination Auditing in Forecasting Time Series Foundation Models

Researchers introduce TSFMAudit, the first systematic method for detecting data contamination in time series foundation models (TSFMs) pretrained on large datasets. The approach identifies contamination by analyzing how quickly models adapt to evaluation data, with contaminated datasets showing unusually efficient loss reduction and minimal backbone movement during fine-tuning.
