High-arity Sample Compression

Learning theorists have extended sample compression, a foundational concept in computational learning theory, into the high-arity regime where multiple learning tasks interact simultaneously. This work establishes that non-trivial high-arity compression schemes guarantee PAC learnability in product spaces, bridging classical sample complexity bounds with multi-task and federated learning settings. The result matters for practitioners building systems that must learn efficiently across correlated domains or distributed data, tightening the theoretical guarantees that underpin generalization in complex learning scenarios.

Search Your Block Floating Point Scales!

Quantization remains a critical bottleneck in generative model deployment, and GPU vendors are now shipping hardware primitives to accelerate it. This paper challenges the conventional wisdom that fixed-scale block floating point quantization is optimal, proposing ScaleSearch to dynamically tune scale factors and reduce precision loss. The technique integrates with existing post-training quantization pipelines, making it immediately applicable to production inference stacks. For teams optimizing model serving costs and latency, this represents a concrete path to squeeze additional performance from microscaling hardware without retraining, directly impacting the economics of LLM inference at scale.

Towards Affordable Energy: A Gymnasium Environment for Electric Utility Demand-Response Programs

Researchers have released DR-Gym, an open-source reinforcement learning environment designed to optimize demand-response programs in electricity grids. The work addresses a critical gap in offline RL: historical smart meter and pricing data alone cannot capture the feedback loop between utility pricing signals and consumer behavior adaptation. By simulating this interactive dynamic, the framework enables utilities to test demand-response policies that shield residential consumers from price volatility while improving grid flexibility. This bridges applied RL research with infrastructure resilience, offering a concrete testbed for sequential decision-making in energy markets where real-world experimentation carries high stakes.

A proximal gradient algorithm for composite log-concave sampling

Researchers have closed a theoretical gap in sampling from composite log-concave distributions, a foundational problem in probabilistic inference and generative modeling. The new proximal gradient algorithm matches state-of-the-art convergence rates for strongly convex objectives while handling composite structure, which appears in variational inference, Bayesian neural networks, and diffusion model training. The result extends beyond log-concave settings, suggesting broader applicability to non-convex sampling challenges that underpin modern generative AI systems.

Multi-Stream LLMs: Unblocking Language Models with Parallel Streams of Thoughts, Inputs and Outputs

Researchers propose a fundamental shift in how language models process information by enabling parallel computation streams rather than sequential message exchange. Current AI agents remain bottlenecked to single-stream architectures inherited from ChatGPT-era designs, preventing simultaneous reading, writing, thinking, and acting. Multi-stream LLMs would allow agents to generate outputs while consuming new inputs and reason across multiple concurrent tasks, directly addressing a core architectural limitation that has persisted despite rapid capability gains. This work targets the infrastructure layer of autonomous agents, particularly in coding and computer-use domains where latency and decision parallelism matter.

The Algorithmic Caricature: Auditing LLM-Generated Political Discourse Across Crisis Events

Researchers are moving beyond shallow detection signals like perplexity to audit whether LLM-generated political text mimics real social behavior during crises. Using a dataset spanning nine major events from COVID-19 to the 2024 election, the work compares synthetic discourse patterns against observed online populations to expose how generative systems may distort political discourse at scale. This shift toward behavioral auditing matters because traditional AI-text detection weakens as models improve, forcing the field to adopt social science methods to catch synthetic manipulation when it matters most: during high-stakes moments when misinformation spreads fastest.

ORCE: Order-Aware Alignment of Verbalized Confidence in Large Language Models

Researchers propose ORCE, a decoupled framework that separates answer generation from confidence calibration in large language models, addressing a critical deployment challenge. Current LLMs often express unwarranted certainty in incorrect outputs, creating safety risks in production systems. By conditioning confidence estimation on fixed answers rather than jointly optimizing both tasks, this method prevents confidence objectives from degrading answer quality while improving the reliability of natural-language uncertainty signals. The approach matters for practitioners building systems where user-facing confidence estimates must be trustworthy, especially when logit access is restricted.

A Causal Language Modeling Detour Improves Encoder Continued Pretraining

Researchers demonstrate that encoder models benefit from a temporary shift to causal language modeling during domain adaptation, followed by masked language modeling decay. Testing on biomedical datasets with ModernBERT shows consistent gains of 0.3-2.8 percentage points across 19 tasks in French and English. The mechanism appears to involve deeper representational changes in lower transformer layers that persist through the subsequent MLM phase, suggesting that pretraining schedules merit reconsideration beyond standard masked language modeling approaches.

Environment-Adaptive Preference Optimization for Wildfire Prediction

Researchers introduce Environment-Adaptive Preference Optimization, a framework addressing a critical gap in ML reliability: models trained on historical data often collapse when deployed into shifted environments, especially for rare high-stakes events like wildfires. EAPO tackles the dual challenge of long-tail imbalance (fires are rare but consequential) and distribution drift by constructing environment-aligned datasets that recalibrate model behavior for new conditions. This work matters beyond wildfire forecasting, signaling growing attention to robustness under real-world deployment constraints, a persistent friction point between research benchmarks and production systems.

Learning Minimally Rigid Graphs with High Realization Counts

Researchers have applied reinforcement learning and graph neural networks to solve a classical extremal problem in rigidity theory: discovering minimally rigid graphs with unusually high realization counts. The work uses Deep Cross-Entropy Method optimization with a Graph Isomorphism Network encoder to navigate the combinatorial explosion of candidate structures via Henneberg construction moves. This bridges discrete mathematics and modern deep learning, demonstrating how RL can tackle exhaustive search problems in non-Euclidean domains where traditional methods fail. The approach matches known optima for planar cases and signals growing capability in using neural methods for structured combinatorial discovery.

Geometric Factual Recall in Transformers

Researchers have identified a fundamentally different mechanism by which transformers store factual knowledge, challenging the prevailing assumption that weight matrices function as direct associative lookups. Rather than scaling parameter counts linearly with facts, the model encodes relational structure through geometric superposition of embeddings, with MLPs acting as selective routers. This finding reshapes how we understand transformer memory efficiency and has implications for scaling language models to handle vastly larger fact sets without proportional parameter growth.

Predicting Disagreement with Human Raters in LLM-as-a-Judge Difficulty Assessment without Using Generation-Time Probability Signals

Researchers have developed a technique to flag when LLM-based difficulty assessments for educational content will diverge from human judgment, enabling targeted re-review rather than blanket human validation. The approach sidesteps the brittleness of generation-time confidence scores by leveraging ordinal structure and embedding spaces like ModernBERT. This addresses a real friction point in scaling LLM-assisted content creation: human raters remain the bottleneck for quality control, but identifying which predictions need human eyes before deployment can reduce wasted annotation effort. The work signals growing maturity in LLM-as-a-Judge workflows, where confidence calibration and disagreement prediction are becoming table stakes for production systems.

Neutralizing the Gigascale Problem: How to Solve the Physical Power Paradox of Extreme AI Training Loads

As AI training clusters scale to gigawatt-level power consumption, infrastructure engineers face a critical constraint: power delivery systems cannot respond fast enough to the microsecond-level load spikes generated by synchronized GPU workloads. The bottleneck has shifted from thermal management or raw capacity to the dynamic stability of the electrical grid feeding data centers. This 'power paradox' means that even with sufficient total power budget, the rapid fluctuations in demand can destabilize rack-level and facility-level power chains, forcing operators to either overprovision resilience or accept performance throttling. Solving this requires rethinking power architecture at the physical layer, not just the computational one.

ORBIT: Preserving Foundational Language Capabilities in GenRetrieval via Origin-Regulated Merging

Researchers have identified catastrophic forgetting as a critical failure mode during fine-tuning of large language models for generative retrieval tasks, where models rapidly lose foundational reasoning abilities as parameters drift from their pretrained state. ORBIT addresses this by monitoring weight distance during training and applying constrained averaging to prevent excessive parameter deviation. This work matters because it tackles a fundamental tension in LLM adaptation: task specialization often comes at the cost of general capability erosion, a problem that scales across any domain-specific deployment. The technique offers practitioners a principled way to preserve base model competence while adapting to downstream objectives, directly impacting production reliability for retrieval-augmented systems.

Aligning Flow Map Policies with Optimal Q-Guidance

Researchers propose flow map policies, a generative control method that accelerates action sampling in reinforcement learning by learning to skip steps within flow-based diffusion dynamics. Rather than simulating full generative trajectories at inference time, the approach enables arbitrary-length jumps including single-step generation, directly addressing the latency bottleneck that has limited diffusion and flow matching policies in sequential decision-making. This bridges a critical gap between the expressivity gains of generative models for multimodal action spaces and their computational cost, making them viable for real-time control in offline-to-online RL settings.

Stories in Space: In-Context Learning Trajectories in Conceptual Belief Space

Researchers propose that large language models perform in-context learning by updating beliefs across low-dimensional geometric manifolds rather than arbitrary hypothesis spaces. By analyzing story comprehension tasks, the work reveals that LLM behavior and internal representations both reflect structured, predictable trajectories as models incorporate new information. This finding advances mechanistic understanding of how LLMs adapt dynamically without retraining, with implications for interpretability, alignment research, and predicting model failure modes under distribution shift.

Predicting Decisions of AI Agents from Limited Interaction through Text-Tabular Modeling

Researchers have formulated a novel prediction problem for multi-agent AI systems: inferring an unfamiliar counterpart's next move in negotiation from limited prior interactions, using a hybrid text-tabular model that combines dialogue, game state, and offer history. This addresses a critical gap in agent-to-agent commerce where one bot must adapt to an opaque opponent's hidden prompts and decision logic. The work moves beyond single-agent benchmarks into the harder terrain of real-world deployment, where agents negotiate with unknown systems and each prediction error carries financial stakes. Success here could unlock more robust autonomous trading and procurement systems.

OGLS-SD: On-Policy Self-Distillation with Outcome-Guided Logit Steering for LLM Reasoning

Researchers tackle a fundamental problem in on-policy self-distillation for LLMs: teacher models generate biased or template-shifted responses during reasoning tasks, corrupting the token-level supervision that students learn from. OGLS-SD addresses this by using outcome rewards to identify which trajectories succeeded or failed, then steering logits to recalibrate teacher guidance before distillation. This bridges a gap between coarse-grained correctness signals and fine-grained learning, potentially improving how LLMs bootstrap their own reasoning without external data. The work matters for scaling reasoning models efficiently, especially as self-improvement becomes central to frontier model development.
