Post-Training in Time Series Foundation Models: A Unifying Framework

Shifeng Xie, Ambroise Odonnat, Zehao Xiao +7

Time series foundation models (TSFMs) have emerged as general-purpose models for time series analysis, but pretraining alone is often insufficient for reliable downstream deploymen…

Toto 2.0: Time Series Forecasting Enters the Scaling Era

Emaad Khwaja, Chris Lettieri, Gerald Woo +10

We show that time series foundation models scale: a single training recipe produces reliable forecast-quality improvements from 4M to 2.5B parameters. We release Toto 2.0, a family…

ARFBench: Benchmarking Time Series Question Answering Ability for Software Incident Response

Stephan Xie, Ben Cohen, Mononito Goswami +6

Time series question-answering (TSQA), in which we ask natural language questions to infer and reason about properties of time series, is a promising yet underexplored capability o…

EIDOS: Latent-Space Predictive Learning for Time Series Foundation Models

Xinxing Zhou, Qingren Yao, Yiji Zhao +5

Most time series foundation models are pretrained by directly predicting future observations, which often yields weakly structured latent representations that capture surface noise…

GDformer: Going Beyond Subsequence Isolation for Multivariate Time Series Anomaly Detection

Qingxiang Liu, Xiaoliang Luo, Chenghao Liu +5

Unsupervised anomaly detection of multivariate time series is a challenging task, given the requirements of deriving a compact detection criterion without accessing the anomaly poi…

A Picture is Worth A Thousand Numbers: Enabling LLMs Reason about Time Series via Visualization

Haoxin Liu, Chenghao Liu, B. Aditya Prakash

Large language models (LLMs), with demonstrated reasoning abilities across multiple domains, are largely underexplored for time-series reasoning (TsR), which is ubiquitous in the r…
