Exploring Multi-Modal Data with Tool-Augmented LLM Agents for Precise Causal Discovery

ACL 2025finding

Causal discovery is an imperative foundation for decision-making across domains, such as smart health, AI for drug discovery and AIOps. Traditional statistical causal discovery methods, while well-established, predominantly rely on observational data and often overlook the semantic cues inherent in…

Harnessing Vision Models for Time Series Analysis: A Survey

IJCAI 2025

Time series analysis has evolved from traditional autoregressive models to deep learning, Transformers, and Large Language Models (LLMs). While vision models have also been explored along the way, their contributions are less recognized due to the predominance of sequence modeling. However, challeng

Multi-Modal View Enhanced Large Vision Models for Long-Term Time Series Forecasting

NeurIPS 2025poster

Time series, typically represented as numerical sequences, can also be transformed into images and texts, offering multi-modal views (MMVs) of the same underlying signal. These MMVs can reveal complementary patterns and enable the use of powerful pre-trained large models, such as large vision models…
