MLToolBench: Learning Tool-Augmented Agents for Machine Learning Development

This work introduces ToolMLBench, a suite of executable tools for data inspection, code verification, and experiment diagnosis, together with an SFT and RL pipeline for learning their use, and measures how privileged context changes the likelihood of a sampled tool action and uses this difference as a turn-level reward...

FairDiff: Mitigating the Self-Reinforcing Matthew Effect in Diffusion Recommender Models

FairDiff is proposed, a plug-and-play fairness-aware diffusion framework that achieves state-of-the-art performance while effectively mitigating the self-reinforcing Matthew Effect, highlighting its value as a general framework for DRMs.

FineSID: Scalable and Efficient Semantic Identifier Learning for Generative Recommendation

FineSID is a unified quantization framework that moves beyond Top-1 assignment by enabling fine-grained gradient propagation across the entire codebook, effectively alleviating SID collisions and stabilizing training in large, high-dimensional codebooks.

RankBuffer: Efficient Ranking-Based Rewards for Open-Ended Generation

RankBuffer is introduced, which maintains an ordered, query-specific buffer of previously judged responses as a reusable quality scale that achieves nearly on-par performance with the strongest ranking-based reward baseline while substantially reducing judging cost.

Distilling Agentic Systems: A Roadmap across Models, Artifacts, and Harnesses

Modern agents increasingly rely on memories, tools, and execution logic, so their competence extends beyond model parameters. This shift exposes a limitation of conventional knowledge distillation, which asks how a student model imitates a teacher model. We define Agent Distillation as the persistent transfer of task-s...

Semantic Projection for Continual Self-Evolution of Language Agents

Semantic-Scope Projected Evolution (SSPE) is introduced, which transfers the functional principle of gradient projection from parameter space to behavior space and establishes semantic projection as a promising principle for stable and adaptive self evolution of language agents.

DualTrack: Synchronized speech-gesture generation via symmetric coupling of pretrained priors

DualTrack is presented, which couples pretrained speech and motion priors on a shared 12.5 Hz timeline, and achieves lower word error rate and full-motion Fr\'echet Gesture Distance, higher beat consistency and speech naturalness than the evaluated GELINA baseline.

Neural Structural Reasoner: A Brain-inspired Architecture for Reasoning over Structured Knowledge

Structural reasoning, the ability to recognize and make inferences over the relational structure between objects and concepts, is a hallmark of human cognition, yet prevailing methods often collapse relational topology into flat embeddings, cannot discover hidden structure and lack interpretability. We introduce Neural...

Multi-Channel Mitigation of Source-Trust Shortcuts in Fact-Checking RL Agents

Retrieval-augmented fact-checkers often receive a reliability label, such as HIGH or LOW trust, for each evidence source. These labels should adjust the model's confidence and its decision to search for more evidence, while the verdict should follow the evidence content. We introduce TrustSwap, a counterfactual test th...

Transformers Stop Thinking Too Early, and a Tiny LoRA Fixes It

Pretrained transformers use little of their depth to follow references in context. Thirteen base models reliably follow only 1.4-3.6 lines, and extra pretrained loops add little. A task-trained rank-8 LoRA at one early layer extends this computation with all model weights frozen. Qwen3-8B improves from 15.5% to 99% exa...

MemEvo: Automatic Discovery of Streaming Video Memory Mechanisms

Query-agnostic streaming video understanding requires vision-language models to continuously compress an indefinitely growing visual stream into a bounded memory before future queries are known. The performance depends critically on the memory mechanism--what observations to preserve, how to represent and consolidate t...

Who we become when we talk to machines

Professor Sherry Turkle’s new book, “Artificial Intimacy,” offers a withering critique of chatbots and the antisocial dynamics she believes they encourage.
