From Time Series Analysis to Question Answering: A Survey in the LLM Era

IJCAI 2026

Recently, Large Language Models (LLMs) have introduced a novel paradigm in Time Series Analysis (TSA), leveraging strong language capabilities to support tasks such as forecasting and anomaly detection. However, these analysis tasks cannot adequately cover temporal language tasks, such as interpreta

Pathformer: Multi-scale Transformers with Adaptive Pathways for Time Series Forecasting

ICLR 2024poster

Transformers for time series forecasting mainly model time series from limited or fixed scales, making it challenging to capture different characteristics spanning various scales. We propose Pathformer, a multi-scale Transformer with adaptive pathways. It integrates both temporal resolution and temp…
