OneShot: Label-Efficient Detector Weighting for Time Series Anomaly Detection

Seunghan Lee, Jun Seo, Jaehoon Lee +9

Time series (TS) anomaly detection (AD) lacks a universal detector, with the best choice determined by the series rather than by the algorithm. Existing methods therefore either se…

XForecast: The KDD 2026 Finance Day Challenge on News-Grounded Financial Forecasting

Jaehoon Lee, Jun Seo, Seunghan Lee +10

Financial forecasting has traditionally relied on numerical time-series (TS) signals, while textual information such as news remains largely underutilized. We introduce XForecast,…

FinVerse: Toward More Realistic Evaluation for Financial Time-Series Forecasting

Jaehoon Lee, Jun Seo, Seunghan Lee +17

Time-series foundation models (TSFMs) are increasingly evaluated on broad benchmarks that apply uniform conventional forecast evaluation metrics across heterogeneous time-series. H…

Traceable Multi-Agent System for Knowledge-Based Forecasting

Junhyeok Kang, Sangjun Han, Hyeokjun Choe +1

Enterprise forecasting increasingly relies on autonomous agents that interpret documents, search for data, generate code, and revise models. While this autonomy helps build adaptiv…

ReasonCast: Towards Explainable Time Series Forecasting with Reasoning

Seunghan Lee, Jun Seo, Jaehoon Lee +9

Most time series (TS) models are specialized for a single task, either understanding (i.e., returning text answers about a TS) or generation (i.e., returning a numeric forecast). O…

Beyond Magnitude and Shape: A Direction-Aware Loss for Time Series Forecasting

Seunghan Lee, Jaehoon Lee, Jun Seo +9

The direction of change --- whether a series will move up or down --- is often as important as its exact value in decisiondriven applications such as risk management and financial…

Channel-wise Retrieval for Multivariate Time Series Forecasting

Junhyeok Kang, Jun Seo, Soyeon Park +4

Multivariate time series forecasting often struggles to capture long-range dependencies due to fixed lookback windows. Retrieval-augmented forecasting addresses this by retrieving…

VarDrop: Enhancing Training Efficiency by Reducing Variate Redundancy in Periodic Time Series Forecasting

Junhyeok Kang, Yooju Shin, Jae-Gil Lee

Variate tokenization, which independently embeds each variate as separate tokens, has achieved remarkable improvements in multivariate time series forecasting. However, employing s…
