Learning What to Learn: Stage-Specific Data Sets for SFT-then-RL in Small Language Model Reasoning

Chongyang He, Rui Zhang, Zixuan Wang +1

Post-training Small Language Models (SLMs) for reasoning typically follows an SFT-then-RL pipeline, yet existing work rarely considers what data should be learned at each stage. We…

CleanCodec: Efficient and Robust Speech Tokenization via Perceptually Guided Encoding

Eugene Kwek, Feng Liu, Rui Zhang +1

Neural audio codecs are a key component of speech processing pipelines, compressing audio into discrete tokens for downstream modeling. However, existing codecs struggle to balance…

Representation Collapse in Sequential Post-Training of Large Language Models

Yichen Liu, Mingyu Chen, Hao Wang +7

Large language models are now adapted through chains of post-training stages rather than through a single instruction-tuning pass. This paper studies whether such sequential post-t…

SEP: Self-Enhanced Prompt Tuning for Visual-Language Model

Hantao Yao, Rui Zhang, Lu Yu +2

Prompt tuning based on Context Optimization (CoOp) effectively adapts visual-language models (VLMs) to downstream tasks by inferring additional learnable prompt tokens. However, th…

TCP:Textual-based Class-aware Prompt tuning for Visual-Language Model

Hantao Yao, Rui Zhang, Changsheng Xu

Prompt tuning represents a valuable technique for adapting pre-trained visual-language models (VLM) to various downstream tasks. Recent advancements in CoOp-based methods propose a…
