arXiv:2602.15228v1 Announce Type: new Abstract: Instruction-tuned Language Models (ILMs) have become essential components of modern AI systems, demonstrating exceptional versatility across natural language and reasoning tasks. Among their most impactful applications is code generation, where ILMs — commonly referred to as Code Language Models (CLMs) — translate human intent into executable programs. While progress has been driven by advances in scaling and training methodologies, one critical aspect remains underexplored: the impact of system prompts on both general-purpose ILMs […]

arXiv:2602.15225v1 Announce Type: new Abstract: We propose a general class of symmetric games called position-optimization games. Given a probability distribution $Q$ over a set of targets $mathcal{Y}$, the $n$ players each choose a position in a space $mathcal{X}$. A player’s utility is the $Q$-mass of targets they are closest to under some proximity measure, with ties broken evenly. Our model captures Hotelling games and forecasting competitions, among other applications. We show that for sufficiently large $n$, both pure […]

arXiv:2602.15222v1 Announce Type: new Abstract: Reward models are central to large language model (LLM) post-training. However, past work has shown that they can reward spurious or undesirable attributes such as length, format, hallucinations, and sycophancy. In this work, we introduce and study the research problem of automatically finding reward model biases in natural language. We offer a simple approach of using an LLM to iteratively propose and refine candidate biases. Our method can recover known biases and surface […]

arXiv:2602.15219v1 Announce Type: new Abstract: The growing complexity in home energy management demands advanced systems that guide occupants toward informed energy decisions. Large language model (LLM)-integrated home energy management systems (HEMS) have shown promise, but prior studies relied on prompt engineering or pre-built platforms with limited customization of agent behavior, or assessed performance through single-turn or -task evaluations. This study introduces a multi-agent home energy management assistant (HEMA), built on LangChain and LangGraph, designed to adaptively and intelligently […]

arXiv:2602.15214v1 Announce Type: new Abstract: Container startup latency is a critical performance metric for CI/CD pipelines, serverless computing, and auto-scaling systems, yet practitioners lack empirical guidance on how infrastructure choices affect this latency. We present a systematic measurement study that decomposes Docker container startup into constituent operations across three heterogeneous infrastructure tiers: Azure Premium SSD (cloud SSD), Azure Standard HDD (cloud HDD), and macOS Docker Desktop (developer workstation with hypervisor-based virtualization). Using a reproducible benchmark suite that executes […]

arXiv:2602.15212v1 Announce Type: new Abstract: In this paper, we introduce a secure wireless agentic AI network comprising one supervisor AI agent and multiple other AI agents to provision quality of service (QoS) for users’ reasoning tasks while ensuring confidentiality of private knowledge and reasoning outcomes. Specifically, the supervisor AI agent can dynamically assign other AI agents to participate in cooperative reasoning, while the unselected AI agents act as friendly jammers to degrade the eavesdropper’s interception performance. To extend […]

arXiv:2602.15210v1 Announce Type: new Abstract: Multilinguality is a core capability for modern foundation models, yet training high-quality multilingual models remains challenging due to uneven data availability across languages. A further challenge is the performance interference that can arise from joint multilingual training, commonly referred to as the “curse of multilinguality”. We study multilingual data curation across thirteen languages and find that many reported regressions are not inherent to multilingual scaling but instead stem from correctable deficiencies in data […]

arXiv:2602.15206v1 Announce Type: new Abstract: Reward learning typically relies on a single feedback type or combines multiple feedback types using manually weighted loss terms. Currently, it remains unclear how to jointly learn reward functions from heterogeneous feedback types such as demonstrations, comparisons, ratings, and stops that provide qualitatively different signals. We address this challenge by formulating reward learning from multiple feedback types as Bayesian inference over a shared latent reward function, where each feedback type contributes information through […]

arXiv:2602.15204v1 Announce Type: new Abstract: This paper presents a distributed memory method for anisotropic mesh adaptation that is designed to avoid the use of collective communication and global synchronization techniques. In the presented method, meshing functionality is separated from performance aspects by utilizing a separate entity for each – a multicore cc-NUMA-based (shared memory) mesh generation software and a parallel runtime system that is designed to help applications leverage the concurrency offered by emerging high-performance computing (HPC) architectures.

arXiv:2602.15201v1 Announce Type: new Abstract: Dexterous grasping is fundamental to robotics, yet data-driven grasp prediction heavily relies on large, diverse datasets that are costly to generate and typically limited to a narrow set of gripper morphologies. Analytical grasp synthesis can be used to scale data collection, but necessary simplifying assumptions often yield physically infeasible grasps that need to be filtered in high-fidelity simulators, significantly reducing the total number of grasps and their diversity. We propose a scalable generate-and-refine […]
