MLToolBench: Learning Tool-Augmented Agents for Machine Learning Development

Xin Yu, Lizhu Zhang, Jiamu Bai +7

Machine learning engineering (MLE) agents have made substantial progress, but learning through ML experimentation remains costly in time and computation. Synthetic environments red…

Difficulty-Aware Semantic-ID Optimization for Generative Recommendation

Xin Yu, Stephen Li, Sina Aghaei +6

Semantic-ID-based generative recommendation casts retrieval and ranking as autoregressive generation over hierarchical item identifiers. A common recipe is SFT followed by GRPO, ye…

Uno-Orchestra: Parsimonious Agent Routing via Selective Delegation

Zhiqing Cui, Haotong Xie, Jiahao Yuan +11

Large language model (LLM) multi-agent systems typically rely on rigid orchestration, committing either to flat per-query routing or to hand-engineered task decomposition, so decom…

Preference-Based Self-Distillation: Beyond KL Matching via Reward Regularization

Xin Yu, Liuchen Liao, Yiwen Zhang +3

On-policy distillation is an efficient alternative to reinforcement learning, offering dense token-level training signals. However, its reliance on a stronger external teacher has…

Train Large, Deploy Compact: Structured Compression for Compact Low-Rank Adaptation

Xin Yu, Cong Xie, Xunmei Liu +3

Low-rank adaptation (LoRA) has become a widely used paradigm for parameter-efficient fine-tuning of large language models, yet its representational capacity often lags behind full…

A New Inexact Manifold Proximal Linear Algorithm with Adaptive Stopping Criteria

Zhong Zheng, Xin Yu, Shiqian Ma +1

This paper proposes a new inexact manifold proximal linear (IManPL) algorithm for solving nonsmooth, nonconvex composite optimization problems over an embedded submanifold. At each…

AltLoRA: Towards Better Gradient Approximation in Low-Rank Adaptation with Alternating Projections

Xin Yu, Yujia Wang, Jinghui Chen +1

Low-Rank Adaptation (LoRA) has emerged as an effective technique for reducing memory overhead in fine-tuning large language models. However, it often suffers from sub-optimal perfo…
