Papers from Monday, 31 August 2026

Language Models: Reasoning, Safety, and Evaluation

  • A formal information-⁠theoretic analysis shows that no text representation, even from large-⁠scale training, can fully recover a speaker’s intended meaning from an utterance alone; uncertainty splits into irreducible linguistic ambiguity and context-⁠dependent parts, with empirical validation on artificial languages, Mandarin zero-⁠pronoun resolution, and color reference [1].
  • ASR errors in voice-⁠controlled embodied AI can degrade safety by introducing harmful ambiguity or weakening refusal behavior; automatic error correction only partially mitigates risks, as shown by evaluations on SafeAgentBench and POEX [2].
  • Test-⁠time scaling in LLM translation reveals that sequential sampling (e.g., Best-⁠of-⁠N) achieves higher performance ceilings and improves fluency/naturalness, but large inference budgets can degrade accuracy; the mechanism is partially attributed to self-⁠improvement dynamics [3].
  • ElephantBench probes LLMs on long-⁠tail divergent knowledge, showing even the strongest models recover both accounts of a fact only 52.4% of the time, with exposure imbalance favoring dominant accounts; scaling and reasoning improve recall but not completeness [4].
  • Linguistic and internal confidence in LLMs often diverge: weak instance-⁠level association, inflated confidence in instruction-⁠tuned models, and misalignment between reported confidence and logits/entropy-⁠based uncertainty across 30 models and 10 tasks [5].

Agentic Systems and Tools

  • Logos introduces a cross-⁠process agent harness (ROS-⁠like) that decouples agent capabilities from a single process, leveraging stateless LLM inference and formal lemmas to ensure soundness across distributed components [6].
  • ContextPilot addresses proactive context management for long-⁠horizon agents by expanding toolsets (global planning, long-⁠term memory, adaptive compression), improving credit assignment via fine-⁠grained RL, and demonstrating gains on long-⁠horizon reasoning tasks [7].
  • PersonaForge synthesizes realistic multi-⁠turn user–agent interactions using a 4D persona space and behavioral controls, with a 6.3K training dataset and a 138-⁠task benchmark; training improves composite scores by +4 on Qwen3.5-⁠27B [8].
  • InstructMesh enables selective refinement of generative 3D models for fabrication via natural language or sliders, operating on latent representations to correct geometric flaws (e.g., voids, thickness) without expert skills [9].

Multimodal and Vision-⁠Language Models

  • GeoNeXt repurposes pretrained video generative models for joint geometry estimation (depth, surface normals) via next-⁠frame prediction, offering a data-⁠efficient alternative to task-⁠specific fine-⁠tuning or joint backbones [10].
  • Sliding Window Attention (SWA) with sinks outperforms post-⁠trained Linear Attention on long-⁠context reasoning (2–10× higher on Needle-⁠in-⁠a-⁠Haystack/BABILong) and matches or exceeds performance on other tasks, challenging the need for complex linear attention retrofits [11].
  • Semantic Head Specialization (SHS) in ViT attention heads correlates with performance; Ariadne Attention, guided by SHS, matches full attention on 22 tasks at 6.5× lower compute by optimizing window interaction, token serialization, and local softmax allocation [12].
  • AcrossVAM1.0 factorizes robot video prediction into object-⁠centric motion (particles) and dense appearance, using a frozen SAM3-⁠DLP codec and a 0.28M-⁠parameter Transformer modulated by CLIP embeddings; outperforms pixel-⁠only baselines on a new VRS benchmark [13].

Efficiency and Optimization

  • Sliding Window Attention (SWA) beats linear attention in cost-⁠performance trade-⁠offs, achieving higher accuracy on long-⁠context tasks while avoiding quadratic scaling [11].
  • Curvature-⁠Conditioned Multiscale Momentum with sphere constraints accelerates LLM pretraining by targeting flat directions in the loss landscape, combining slow- and fast-⁠decay momentum components for noise reduction and rapid adaptation [14].
  • Communication-⁠Efficient MoE (CE-⁠MoE) reduces training costs by 33.3% at 31.5B parameters by concentrating expert capacity in select routed layers while maintaining depth via additional token-⁠mixing/FFN layers, improving downstream scores and inference throughput [15].
  • A survey of modern optimizers highlights matrix-⁠aware methods (e.g., Muon, Shampoo) as genuine advances, but notes no context-⁠independent replacement for AdamW; rankings vary with model scale and task [16].

Security and Robustness

  • CamoDocs poisons RAG systems by camouflaging adversarial documents among benign content, avoiding query-⁠overlap artifacts and achieving strong attack success rates (ASR) across seven defenses, three LLMs, and three benchmarks [17].
  • REPLICANT uses deep RL to learn transferable evasion policies against malware detectors under a strict label-⁠only black-⁠box threat model, achieving 78.8% mean ASR (20.9–39.2% relative improvement) and enabling adversarial training to harden detectors [18].
  • Fidelity checks alone are insufficient for agentic document extraction: dispatch-⁠level instrumentation (tool-⁠call logging) exposes silent failures where models bypass tool use and fabricate answers, with a rule-⁠based detector recovering all planted faults [19].

Benchmarks and Datasets

  • NL2AGBench evaluates LLM auto-⁠formalization for AlphaGeometry, using execution-⁠based verification to assess translation quality from natural language to DSL, addressing a key bottleneck in neuro-⁠symbolic geometry [20].
  • CultureConverse introduces a multilingual, multi-⁠turn simulation harness for culturally grounded assistant dialogue across 10 East/Southeast Asian regions, with 14.6K benchmark episodes and 274K oracle dialogues; fine-⁠tuning improves cultural alignment [21].
  • Phoneme-⁠Cluster Mutual Information (PCMI) and Word Acoustic Consistency Score (WACS) enable reference-⁠free forced alignment evaluation using self-⁠supervised speech representations, validated on 85 languages (FLEURS) and 45 languages (DoReCo) [22].

Specialized Domains and Software Verification

  • Aero Hand Open releases a simulation-⁠ready tendon-⁠driven anthropomorphic hand with a cable transmission model, identified actuation map, and RL package, addressing the challenges of underactuated, coupled joints in dexterous manipulation learning [23].
  • ARC-⁠CT proposes anatomy-⁠routed contrastive learning for 3D chest CT, localizing abnormalities via LLM-⁠extracted labels and organ masks, addressing limitations of global contrastive methods [24].
  • Real-⁠time virtual circuits for plasma shape control in tokamaks are experimentally validated on MAST Upgrade, replacing offline look-⁠up tables with neural network emulators while retaining interpretability and control performance [25].
  • Verus enables development of provably correct Rust code by extending Rust’s type system to formally verify safety and functional correctness, addressing limitations where Rust’s runtime checks (e.g., bounds) are safer than C but do not guarantee logical correctness or security properties [26].
