Reinforcement Learning and Language Models

  • Exploration-⁠Distillation Framework: To prevent novelty incentives from degrading model quality during reinforcement learning with verifiable rewards (RLVR), the Exploration-⁠Distillation (ExpDis) framework decouples exploration from optimization by alternating between training explorer policies with a novelty bonus and distilling filtered, high-⁠quality trajectories into a student policy trained without novelty bonuses [1].
  • Attribution in Online RL: An open evaluation harness named BehaviorTrace shows that much of the apparent attribution signal in online RL fine-⁠tuning comes from confounds, where simple gradient-⁠size controls or model fluency can predict behavior labels as well as or better than targeted attribution methods [2].
  • Multi-⁠Teacher On-⁠Policy Distillation: The Δ-⁠MOPD method improves multi-⁠teacher on-⁠policy distillation by transferring each teacher’s logit shift re-⁠anchored at the student’s frozen initialization, successfully removing the impediment where inherited base pull exceeds post-⁠training shifts [3].
  • Privileged Teacher Matching: Privileged information in self-⁠distillation can cause teachers to solve tasks through shortcuts unavailable to the student, leading to supervision mismatches that degrade student performance [4].

Architecture, Optimization, and Inference

  • Decentralized Optimization under Heavy-⁠Tailed Noise: Clipped decentralized SGD (mathttDSGD) achieves order-⁠optimal convergence rates both in expectation and with high probability for smooth non-⁠convex costs under bounded $p$-th moment noise where p ∈ (1,2] [5].
  • Conditional Memory Updates: EngramEdit updates factual knowledge in large language models while keeping the Transformer backbone fixed by computing target memory representations across multiple expressions and jointly updating shared $n$-gram embeddings [6].
  • Graph Geometry Distillation: The Graph Geometry-⁠aware MLP (G²MLP) framework uses Ollivier-⁠Ricci curvature to allocate supervision during distillation, preventing spectral underfit on sparse graphs and spectral overfit on dense graphs [7].
  • Speculative Decoding Optimization: Framing speculative decoding as a Markov reward process yields the Expected Decoding Rounds (EDR) objective, which directly optimizes global decoding efficiency by weighting local rejection costs by state occupancies [8].
  • Softmax Sampling Correction: Size-⁠Corrected 2LS (S-⁠2LS) and Size- and Dispersion-⁠Corrected 2LS (SD-⁠2LS) correct systematic biases in two-⁠level softmax sampling caused by size imbalance and intra-⁠cluster dispersion [9].

Robotics and Embodied AI

  • Persistent 3D Object Memory: Ledger is a persistent 3D object memory for embodied assistants that combines object locations, histories, and contextual descriptions from egocentric videos, clustering observations by resting locations to reduce localization noise [10].
  • Scaling Context in World-⁠Action Models: Long-⁠WAM demonstrates that scaling context in causal world-⁠action models improves robot control success significantly when using autoregressive pretraining, raising success on RoboCasa GR-⁠1 from 63.3% to 78.7% with a 19.2-⁠second context window [11].
  • Language Sensitivity in VLAs: Vision-⁠language-⁠action models exhibit extreme sensitivity to instruction phrasing, where minor wording edits cause large success drops, but this sensitivity can be mitigated using distilled rephrasing rules without modifying policy weights [12].
  • Robotic Latent World Models: RoboJEPA is a latent world model trained across 12 robotic embodiments whose imagination error follows a second-⁠order power law in compute, serving as a reliable proxy for downstream robotic planning performance [13].
  • Active Continual Robot Learning: EmbodiedRSI is a self-⁠evolving agentic harness that uses a dual-⁠system architecture, a Hypothesis Graph, and Value-⁠of-⁠Information Experiment Selection to autonomously guide physical exploration and code-⁠skill co-⁠evolution [14].

Scientific Applications, Evaluation Benchmarks, and Applied Systems

  • Climate Model Discovery: The AI Science Exam for ENSO (SciExam for ENSO) benchmarks AI agents on building low-⁠order stochastic climate models from real observations, with six out of twelve agent systems producing models that outperform published benchmarks in reconstruction and forecasting [15].
  • Stated-⁠Preference Economics for LLM Evaluation: Stated-⁠preference economic frameworks provide validity and reliability tests for evaluating language models on subjective questions that lack ground-⁠truth answers, demonstrated on a water-⁠quality economic valuation survey [16].
  • Post-⁠Hallucination Reasoning: PHRBench evaluates 18 language models across 4,820 controlled instances, revealing that successful recovery from hallucinated premises is rare and correlates with frequent belief updates along the reasoning trajectory [17].
  • Institutional Design for Research Agents: Designing explicit institutions for large populations of autonomous research agents, such as a multi-⁠agent society with peer-⁠reviewed grant allocation, enables a population of ten thousand agents to discover pretraining compute savings [18].
  • Ultraviolet Sky Mapping: Claude Science was used to help produce a complete map of the sky in ultraviolet light by predicting about a third of the map, including much of the galactic plane [19].
  • Vulnerability Scanning Service: OSS Scanner is an opt-⁠in vulnerability finding service for open-⁠source software that provides thorough, periodic security scans using strong models, drawing on benchmarks where LLM vulnerability discovery rates rose from under 20% to over 85% [20].
