Papers from Thursday, 23 July 2026

22 papers

Language Models: Alignment, Reasoning, Safety

  • LKValues introduces the first Sri Lankan value-⁠alignment resource suite: 40 majority-⁠endorsed societal values, a 150k Sinhala-⁠English instruction corpus (LKvaluesIT), and a 1k-⁠instance benchmark (LKvaluesBench), revealing cultural bias in existing LLMs and enabling localized evaluation and fine-⁠tuning [1].
  • SoftReason proposes a fully differentiable neuro-⁠soft-⁠symbolic architecture for deductive reasoning over high-⁠dimensional perceptual data, using a learned differentiable lift of the immediate-⁠consequence operator to bridge perception and symbolic deduction without a discrete interface [2].
  • PyroDash enables cost-⁠efficient, token-⁠level collaboration between a small and a large language model, where the SLM dynamically requests LLM assistance via a control token and is trained with cost-⁠aware alignment to balance accuracy and inference cost [3].
  • PoTRE presents a heterogeneous reasoning ensemble with four specialized agents (adversarial refinement, hierarchical planning, spectrum search, direct chain) and a task-⁠adaptive aggregation layer, achieving state-⁠of-⁠the-⁠art on Humanity’s Last Exam (49.92%) [4].
  • Notes to Self shows LLMs can extract and reuse experiential abstractions (strategies, reminders) from their own solution traces, improving performance on math and logic benchmarks via retrieval or RL-⁠augmented prompts [5].
  • Train the Model, Not the Reader exposes flaws in reconstruction-⁠based faithfulness tests for activation explanations, introduces audit protocols (grounded-⁠vs-⁠true cross, evaluator swap), and proposes RECAP to keep explanations readable and verifiable [6].
  • Sound Probabilistic Safety Bounds introduces a framework using Clopper-⁠Pearson intervals and latent-⁠space prioritization to compute rigorous lower/upper bounds on the probability that an LLM generates harmful output for a given prompt [7].
  • OpenSkillRisk benchmarks agent safety with 263 real-⁠world risky third-⁠party skills across seven threat categories, evaluating how well agents recognize and avoid latent execution risks [8].

Multimodal and Vision-⁠Language Models

  • Modality Order Consistency reveals VLMs’ sensitivity to input order (image-⁠first vs. question-⁠first), and proposes a test-⁠time training method that closes the gap and even improves the stronger branch, with activation patching localizing the failure to mid-⁠network layers [9].
  • Culturally Loaded MT constructs a Chinese–Japanese dataset from Dream of the Red Chamber and shows frontier LLMs struggle with culturally loaded expressions, while human evaluator backgrounds cause substantial disagreement in judgments [10].
  • HalluTruthQA introduces a fine-⁠grained Arabic QA benchmark with 2,400 examples, providing character-⁠level hallucination spans, explanations, and multiple-⁠choice verification to support detection, localization, and explanation [11].

Robotics and Embodied AI

  • Miniature Humanoid Tele-⁠Loco-⁠Manipulation adapts VR upper-⁠body teleoperation and RL-⁠based locomotion to a low-⁠cost miniature humanoid (ROBOTIS OP3), achieving 0.45 m/s walking independent of arm motions and demonstrating full-⁠body telepresence control [12].
  • DEED presents a data-⁠efficient post-⁠training and experience-⁠driven learning framework for VLA humanoids, evaluated on supermarket chip-⁠restocking with Unitree G1-⁠Edu and GR00T, highlighting systems integration as key to closing the lab-⁠to-⁠store gap [13].
  • Courteous Anticipation proposes a planning approach where robots anticipate future tasks and others’ constraints, selecting actions that minimize both immediate and expected future costs across all agents in shared environments [14].

Scientific Machine Learning and Optimization

  • PG-⁠KINN combines Kolmogorov-⁠Arnold Networks with a Petrov-⁠Galerkin formulation for solving forward/inverse PDEs, avoiding strong-⁠form derivative requirements and energy-⁠form limitations, and demonstrating superior accuracy and interpretability [15].
  • Label-⁠Free FVM-⁠Residual Training trains attention graph neural networks for 3D thermo-⁠fluid fields by minimizing finite-⁠volume residuals on the mesh, eliminating labeled data needs and outperforming supervised baselines on steady and transient cases [16].
  • iPANN/fPANN introduce interval and fuzzy physics-⁠augmented neural networks for uncertainty-⁠aware hyperelastic constitutive modeling, encoding mechanistic constraints and promoting interpretable energy representations via smoothed L0 regularization [17].

Datasets and Resources

  • Persian Pixel releases a large-⁠scale synthetic OCR dataset for Persian, addressing the language’s cursive connectivity, context-⁠dependent glyphs, ligatures, and diacritics, and providing a path to robust Persian OCR systems [18].
  • Generative AI and Book Markets analyzes 14,419 self-⁠published Amazon books (2023–2026), finding AI-⁠detected books (>25% AI text) win a growing share of sales and top-⁠rank positions, diluting revenue per book as catalog growth outpaces revenue [19].

Ethics, Governance, and Societal Impact

  • License Laundering traces 232,270 dataset→model→application chains, finding 62.3% pass through artifacts with no declared license and that permissive licenses dominate end-⁠to-⁠end (95.1% survival), while obligation-⁠bearing licenses fall below 7% [20].
  • AI-⁠Mediated Library Engagement shows generative AI (ChatGPT, Perplexity, Gemini) increasingly drives traffic to academic repositories, particularly for open-⁠access theses and dissertations with structured metadata [21].
  • Offensive Security Agents argues LLM-⁠driven autonomous agents introduce indeterminacy in actions, impact, and user base, enabling industrialized offensive capabilities and lowering the skill floor for cyberattacks [22].
