Delving into Large Language Models for Effective Time-Series Anomaly Detection

NeurIPS 2025poster

Recent efforts to apply Large Language Models (LLMs) to time-series anomaly detection (TSAD) have yielded limited success, often performing worse than even simple methods. While prior work has focused solely on downstream performance evaluation, the fundamental question—why do LLMs struggle with TSA…

Opt-Out: Investigating Entity-Level Unlearning for Large Language Models via Optimal Transport

ACL 2025long

Instruction-following large language models (LLMs), such as ChatGPT, have become widely popular among everyday users. However, these models inadvertently disclose private, sensitive information to their users, underscoring the need for machine unlearning techniques to remove selective information fr…

Revisiting LLMs as Zero-Shot Time Series Forecasters: Small Noise Can Break Large Models

ACL 2025short

Large Language Models (LLMs) have shown remarkable performance across diverse tasks without domain-specific training, fueling interest in their potential for time-series forecasting. While LLMs have shown potential in zero-shot forecasting through prompting alone, recent studies suggest that LLMs la…
