PEToolLLM: Towards Personalized Tool Learning in Large Language Models

ACL 2025finding

Tool learning has emerged as a promising direction by extending Large Language Models’ (LLMs) capabilities with external tools. Existing tool learning studies primarily focus on the general-purpose tool-use capability, which addresses explicit user requirements in instructions. However, they overloo…

Towards Dynamic Theory of Mind: Evaluating LLM Adaptation to Temporal Evolution of Human States

ACL 2025long

As Large Language Models (LLMs) increasingly participate in human-AI interactions, evaluating their Theory of Mind (ToM) capabilities - particularly their ability to track dynamic mental states - becomes crucial. While existing benchmarks assess basic ToM abilities, they predominantly focus on stati…

Enhancing Tool Retrieval with Iterative Feedback from Large Language Models

EMNLP 2024finding

Tool learning aims to enhance and expand large language models’ (LLMs) capabilities with external tools, which has gained significant attention recently. Current methods have shown that LLMs can effectively handle a certain amount of tools through in-context learning or fine-tuning. However, in real…

Balanced Meta Learning and Diverse Sampling for Lifelong Task-Oriented Dialogue Systems

AAAI 2023technical

In real-world scenarios, it is crucial to build a lifelong taskoriented dialogue system (TDS) that continually adapts to new knowledge without forgetting previously acquired experiences. Existing approaches mainly focus on mitigating the catastrophic forgetting in lifelong TDS. However, the transfer…

Class Incremental Learning for Task-Oriented Dialogue System with Contrastive Distillation on Internal Representations (Student Abstract)

AAAI 2023technical

The ability to continually learn over time by grasping new knowledge and remembering previously learned experiences is essential for developing an online task-oriented dialogue system (TDS). In this paper, we work on the class incremental learning scenario where the TDS is evaluated without specifyi…

Continual Learning for Task-oriented Dialogue System with Iterative Network Pruning, Expanding and Masking

ACL 2021short

This ability to learn consecutive tasks without forgetting how to perform previously trained problems is essential for developing an online dialogue system. This paper proposes an effective continual learning method for the task-oriented dialogue system with iterative network pruning, expanding, and…
