Optimization of randomized neural networks for transfer operator approximation

Researchers introduce RaNNDy, a randomized neural network method that fixes hidden-layer weights while training only the output layer for approximating transfer operators in dynamical systems. The approach trades full optimization for computational efficiency and closed-form solutions, shifting the bottleneck to activation function selection. This represents a practical trade-off in the broader push toward sample-efficient and computationally lean neural architectures, particularly relevant for scientific computing and systems where training cost dominates.

Relevant Walk Search for Explaining Graph Neural Networks

Researchers have cracked a major computational bottleneck in GNN explainability. Layer-wise relevance propagation for graph neural networks previously required exponential time to identify which information flows mattered most, limiting its real-world use. This work reduces that to polynomial time via new algorithms for extracting top-K relevant walks, making higher-order explanations practical at scale. For practitioners deploying GNNs in safety-critical domains like finance or healthcare, this unlocks interpretability methods that were theoretically sound but computationally prohibitive.

OpenAI burned through $1.22 per dollar earned even after stripping out stock-based compensation

OpenAI's Q1 2026 financials reveal a widening unit economics crisis: the company burned $1.22 for every dollar of revenue despite $5.7 billion in quarterly sales, with adjusted operating margins at minus 122 percent. This signals that even after normalizing for stock compensation, the frontier lab's path to profitability remains severely constrained by inference costs and capital intensity. The gap between revenue scale and operational losses underscores a structural challenge facing the entire LLM industry: whether current pricing models and deployment architectures can ever sustain profitable AI services at scale.

OnePred: Next-Query Prediction via Recursive Intent Memory in Multi-Turn Conversations

Researchers introduce OnePred, a framework addressing a fundamental limitation in conversational AI: systems today remain reactive, responding only after users submit queries. The work tackles next-query prediction by compressing dialogue history into an evolving intent trajectory rather than naively concatenating full context, solving a critical efficiency-accuracy tradeoff that scales poorly with conversation length. This shift toward proactive interaction represents a meaningful step in making LLM assistants anticipatory rather than purely responsive, with implications for how dialogue systems might evolve beyond turn-by-turn reactivity.

OpenSkillEval: Automatically Auditing the Open Skill Ecosystem for LLM Agents

OpenSkillEval addresses a critical gap in the LLM agent ecosystem: as structured skills become central to agent performance, there's no standardized way to evaluate skill quality or guide practitioners through cost-performance tradeoffs. This framework automatically audits skills across real-world task categories, moving beyond static benchmarks to test how different models and agent frameworks actually interact with skills in production conditions. For teams building agent systems, this shifts skill selection from guesswork to data-driven evaluation, potentially accelerating adoption of skill-augmented architectures across industry applications.

CVSearch: Empowering Multimodal LLMs with Cognitive Visual Search for High-Resolution Image Perception

CVSearch addresses a critical constraint in multimodal LLM deployment: processing high-resolution images without prohibitive computational overhead. The framework uses adaptive search scheduling, combining efficient expert-guided proposals with fallback semantic-aware scanning to maintain coverage while reducing redundancy. This training-free approach matters because resolution handling directly impacts real-world MLLM utility across document analysis, medical imaging, and visual reasoning tasks. The technique bridges the false choice between speed and completeness, potentially unlocking practical gains for production systems handling dense visual inputs.

How Human-Like Are Large Language Models? A Register-Aware Linguistic Evaluation Framework

Researchers propose a register-aware evaluation framework that measures how linguistically human-like LLM outputs truly are, moving beyond task accuracy to assess whether generated text matches the statistical patterns of human language in specific communicative contexts. This addresses a gap in LLM evaluation: models can produce factually correct responses that still feel unnatural because they violate subtle distributional patterns in vocabulary, syntax, and co-occurrence that humans internalize for different registers (formal, casual, technical, etc.). The work signals growing attention to output naturalness as a distinct quality metric from correctness, with implications for how practitioners should benchmark and refine models for real-world deployment where linguistic authenticity affects user trust and readability.

Learning Kernel-Based MDPs from Episodic Preferential Feedback

Researchers have formalized a theoretical framework for training reinforcement learning systems using only human preference comparisons rather than explicit reward signals, a shift that mirrors how RLHF systems like ChatGPT learn from human feedback. The work extends kernel-based MDP theory to handle preference-only learning, developing new confidence-set methods for episodic settings where two policies are compared head-to-head. This addresses a practical bottleneck in RLHF: humans find it easier to say which output is better than to assign numerical scores. The rigor here matters for practitioners scaling preference-based training, as it provides theoretical guarantees on sample efficiency and convergence that were previously missing in this setting.

Learning Through Noise: Why Subliminal Learning Works and When It Fails

Researchers challenge the conventional wisdom that subliminal learning in neural networks requires matched teacher-student initialization, demonstrating instead that knowledge transfer through task-unrelated distillation depends on compatible output head architecture. This finding reshapes how practitioners should think about model distillation and knowledge transfer, suggesting that architectural alignment matters more than weight initialization parity. The work has implications for efficient model compression and transfer learning workflows, particularly in scenarios where initialization constraints have previously been treated as mandatory.

DiLaDiff: Distilled Latent-Augmented Diffusion for Language Modeling

DiLaDiff addresses a fundamental bottleneck in diffusion language models: the inability to capture token interdependencies forces a painful choice between generation quality and speed. The approach layers three components, a semantic latent space derived from masked diffusion models, a learned prior over that space, and consistency distillation to compress inference into few-step sampling. The result accelerates inference while maintaining or improving output fidelity, potentially reshaping how practitioners balance throughput against coherence in production deployments where diffusion models compete with autoregressive alternatives.

Structure-Guided Entity Resolution: Fine-Tuning LLMs for Robust Name Matching in Complex Linguistic Contexts

Researchers propose Structure-Guided Entity Resolution, a curriculum-learning approach that fine-tunes LLMs to handle the linguistic and structural ambiguities inherent in cross-record name matching. The work targets a persistent pain point in compliance workflows: LLMs excel at semantic understanding but falter when confronted with the rigid, error-prone nature of real-world identity data across scripts and transliteration schemes. By decomposing the problem into grammatical parsing followed by structured optimization, SGER demonstrates how domain-specific fine-tuning can bridge the gap between general language capability and specialized entity resolution tasks. This matters for fintech and compliance teams relying on KYC pipelines, and signals a broader trend of LLMs moving beyond chat into deterministic, high-stakes data operations.

Asking For An Old Friend: Diagnosing and Mitigating Temporal Failure Modes in LLM-based Statutory Question Answering

Researchers have identified a critical vulnerability in LLM-based legal systems: models fail when statutory law evolves beyond their training data, either by applying outdated rules or over-weighting recent provisions regardless of temporal relevance. A new benchmark of 312 German statutory QA pairs tests how GPT, Claude, and DeepSeek handle temporal reasoning across vanilla, web-search, and retrieval-augmented inference modes. This work exposes a fundamental mismatch between static parametric knowledge and dynamic legal systems, forcing practitioners to rethink deployment strategies for high-stakes domains where legal accuracy depends on knowing which version of a rule applies to a given fact pattern.

ARES: Automated Rubric Synthesis for Scalable LLM Reinforcement Learning

ARES addresses a critical bottleneck in LLM reinforcement learning: the manual labor required to build rubrics and evaluation datasets for open-ended tasks. By automating the synthesis of question-specific reward rubrics from raw documents, the framework enables instance-level supervision at scale, moving beyond fixed task-level evaluation. This matters because rubric-based RL is one of the few viable paths to train models on subjective, knowledge-intensive problems without human annotation at every step. The approach could reshape how teams approach RLHF workflows and reduce the engineering overhead that currently limits RL adoption beyond benchmark tasks.

SSDAU: Structured Semantic Data Augmentation for Joint Entity and Relation Extraction

Data augmentation remains a critical bottleneck in training extraction models on noisy or limited datasets. This paper addresses a real pain point: existing augmentation techniques often corrupt semantic relationships when generating synthetic training examples, degrading downstream performance. SSDAU preserves entity-relation structure by segmenting text around labeled entities and using context-aware encoding to restructure semantic content during augmentation. For practitioners building information extraction systems across domains, this approach could reduce the manual labeling burden and improve cross-domain generalization without sacrificing data quality. The work signals ongoing maturation in data-centric AI practices.

Metacognition as Reward: Reinforcing LLM Reasoning via Knowledge and Regulation Signals

Researchers propose Metacognition-as-Reward, a reinforcement learning framework that moves beyond binary outcome signals and rubric-based scoring to guide LLM reasoning through two process dimensions: metacognitive knowledge and metacognitive regulation. The approach addresses a critical gap in current RL methods, which either provide sparse feedback on intermediate steps or demand labor-intensive, task-specific rubric design. By treating the model's own reasoning process as a reward signal, MaR offers a more generalizable path to improving reasoning quality across diverse tasks without per-instance customization. This matters for practitioners scaling RL-based reasoning systems, as it potentially reduces the engineering overhead while maintaining fine-grained guidance on how models should think, not just what they should output.

The work addresses a critical gap in agentic systems: current RL approaches optimize for universal correctness, but real-world deployments require personalized planning and tool-use strategies. By embedding personalization into training-time optimization rather than post-hoc adaptation, this framework tackles entanglement between task quality and conformity effects, opening pathways for agents that scale across diverse user populations without retraining. This matters for production agentic systems where one-size-fits-all policies fail.
