Thinker: Training LLMs in Hierarchical Thinking for Deep Search via Multi-Turn Interaction

AAAI 2026technical

Efficient retrieval of external knowledge bases and web pages is crucial for enhancing the reasoning abilities of LLMs. Previous works on training LLMs to leverage external retrievers for solving complex problems have predominantly employed end-to-end reinforcement learning. However, these approache

Improving Generated and Retrieved Knowledge Combination Through Zero-shot Generation

ICASSP 2025accepted

Open-domain Question Answering (QA) has garnered substantial interest by combining the advantages of faithfully retrieved passages and relevant passages generated through Large Language Models (LLMs). However, there is a lack of definitive labels available to pair these sources of knowledge. In orde…

Label Dependencies-Aware Set Prediction Networks for Multi-Label Text Classification

ICASSP 2024accepted

Multi-label text classification involves extracting all relevant labels from a sentence. Given the unordered nature of these labels, we propose approaching the problem as a set prediction task. To address the correlation between labels, we leverage Graph Convolutional Networks and construct an adjac…
