Is PRM Necessary? Problem-Solving RL Implicitly Induces PRM Capability in LLMs

NeurIPS 2025poster

The development of reasoning capabilities represents a critical frontier in large language models (LLMs) research, where reinforcement learning (RL) and process reward models (PRMs) have emerged as predominant methodological frameworks. Contrary to conventional wisdom, empirical evidence from DeepSe…

Retrieval-Generation Synergy Augmented Large Language Models

ICASSP 2024accepted

Large language models augmented with task-relevant documents have demonstrated impressive performance on knowledge-intensive tasks. However, regarding how to obtain effective documents, the existing methods are mainly divided into two categories. One is to retrieve from an external knowledge base, a…

SkillNet-X: A Multilingual Multitask Model with Sparsely Activated Skills

ICASSP 2024accepted

Traditional multitask learning methods typically can only leverage shared knowledge within specific tasks or languages, resulting in a loss of either cross-language or cross-task knowledge. This paper proposes a general multilingual multitask model, named SkillNet-X, which enables a single model to…

Improved Visual Story Generation with Adaptive Context Modeling

ACL 2023findings

Diffusion models developed on top of powerful text-to-image generation models like Stable Diffusion achieve remarkable success in visual story generation. However, the best-performing approach considers historically generated results as flattened memory cells, ignoring the fact that not all precedin…

Exploring and Adapting Chinese GPT to Pinyin Input Method

ACL 2022long

While GPT has become the de-facto method for text generation tasks, its application to pinyin input method remains unexplored. In this work, we make the first exploration to leverage Chinese GPT for pinyin input method. We find that a frozen GPT achieves state-of-the-art performance on perfect pinyi…

“Is Whole Word Masking Always Better for Chinese BERT?”: Probing on Chinese Grammatical Error Correction

ACL 2022findings

Whole word masking (WWM), which masks all subwords corresponding to a word at once, makes a better English BERT model. For the Chinese language, however, there is no subword because each token is an atomic character. The meaning of a word in Chinese is different in that a word is a compositional uni…

GraphCodeBERT: Pre-training Code Representations with Data Flow

ICLR 2021poster

Pre-trained models for programming language have achieved dramatic empirical improvements on a variety of code-related tasks such as code search, code completion, code summarization, etc. However, existing pre-trained models regard a code snippet as a sequence of tokens, while ignoring the inherent…
