Predict, Don't Iterate: Efficient Adaptive-Length Infilling for Diffusion Language Models

Haobo Xu, Sirui Chen, Yuanchen Bei +5

Diffusion language models (DLMs) have emerged as a promising alternative to the auto-regressive paradigm. With bidirectional attention and any-order generation, DLMs naturally fit…

Astar: Learning to Propose Evolution Directions for Self-Evolving Industrial AI Systems

Jinxin Hu, Hao Deng, Haibo Xing +12

Modern AI systems advance through continuous iteration: a loop of proposing evolution directions, implementing code, training, and evaluation. While the latter three stages are inc…

Trie-Aware Transformers for Generative Recommendation

Zhenxiang Xu, Jiawei Chen, Sirui Chen +5

Generative recommendation (GR) aligns with advances in generative AI by casting next-item prediction as token-level generation rather than score-based ranking. Most GR methods adop…

Influence-Preserving Proxies for Gradient-Based Data Selection in LLM Fine-tuning

Sirui Chen, Yunzhe Qi, Mengting Ai +4

Supervised fine-tuning (SFT) relies critically on selecting training data that most benefits a model's downstream performance. Gradient-based data selection methods such as TracIn…
