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...

Divide and Inject: Can Agents Reconstruct an Indirect Prompt Injection from Fragments?

Agentic systems are now being widely used to orchestrate tools and reason over long contexts. However, the improving capabilities of the large language models powering these agents also create new attack surfaces for indirect prompt injection. In particular, an attacker may not need to place a complete malicious instru...

Visual sensitivity is not claim retractability: persistence-aware credit assignment for multimodal reinforcement learning

Persistence-Aware Credit Gating (PACG), which attenuates positive credit for unusually persistent visual claims and leaves all other credit unchanged, which extends to a larger model, a newer backbone, and the accuracy of HallusionBench also improves consistently.

BRIDGE: Bilevel Retrieval-Credit-Aware Agentic Reinforcement Learning

Agentic reinforcement learning (ARL) with verifiable rewards improves the ability of large language models (LLMs) to tackle knowledge-intensive tasks by learning to interleave search and reasoning. However, most existing ARL methods optimize only LLM-generated tokens and treat retrieved evidence as environment observat...

AVIO: Learning to Add and Remove Sounding Objects in Audiovisual Scenes

A pretrained text-to audiovisual generation model is adapted through source-conditioned feature modulation to jointly learn object addition and removal, and quantitative and qualitative evaluations demonstrate effective audiovisual object removal and addition.

Human-AI Collaboration: From Paradoxes to Patterns

Two key design dimensions of human-AI collaboration (autonomy and initiative) are examined and the collaboration patterns that they generate are explored, including Instruction, Delegation, Assistance, and Co-creation.

Learning to Harvest Without Collapse in a Regenerative Commons: A Lagrangian Framework

A nonstationary Lagrangian framework that constructs a policy sequence from solutions of unconstrained games or cooperative control problems, and proves a reward-independent feasibility certificate, cooperative feasibility and approximate optimality against feasible policy mixtures, and an extension to unbiased sampled...

Going Beyond State-Reaching: Learning Abstractions for Intrinsically Motivated Option Discovery

This work introduces an algorithm that identifies a small, relevant subset of features for each subgoal, yielding options that generalize broadly and accelerate exploration in three sparse-reward, image-based domains, including the Atari game MontezumasRevenge.

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.
