Improving Tool Retrieval by Leveraging Large Language Models for Query Generation

COLING 2025industry

Using tools by Large Language Models (LLMs) is a promising avenue to extend their reach beyond language or conversational settings. The number of tools can scale to thousands as they enable accessing sensory information, fetching updated factual knowledge, or taking actions in the real world. In suc…

MEND: Meta Demonstration Distillation for Efficient and Effective In-Context Learning

ICLR 2024poster

Large Language models (LLMs) have demonstrated impressive in-context learning (ICL) capabilities, where a LLM makes predictions for a given test input together with a few input-output pairs (demonstrations). Nevertheless, the inclusion of demonstrations poses a challenge, leading to a quadratic inc…

KEPLET: Knowledge-Enhanced Pretrained Language Model with Topic Entity Awareness

EMNLP 2023long findings

In recent years, Pre-trained Language Models (PLMs) have shown their superiority by pre-training on unstructured text corpus and then fine-tuning on downstream tasks. On entity-rich textual resources like Wikipedia, Knowledge-Enhanced PLMs (KEPLMs) incorporate the interactions between tokens and men…

Joint Goal Segmentation and Goal Success Prediction on Multi-Domain Conversations

COLING 2022main

To evaluate the performance of a multi-domain goal-oriented Dialogue System (DS), it is important to understand what the users’ goals are for the conversations and whether those goals are successfully achieved. The success rate of goals directly correlates with user satisfaction and perceived useful…

Overcoming Catastrophic Forgetting During Domain Adaptation of Seq2seq Language Generation

NAACL 2022long

Seq2seq language generation models that are trained offline with multiple domains in a sequential fashion often suffer from catastrophic forgetting. Lifelong learning has been proposed to handle this problem. However, existing work such as experience replay or elastic weighted consolidation requires…
