This paper addresses sampling-based motion planning for continuous-time stochastic systems under process and measurement uncertainty, with probabilistic guarantees on safety and performance. It models robot dynamics as a continuous-time linear stochastic differential equation and uses discrete-time sensor measurements. A hybrid belief propagation model is derived, where belief evolves via continuous-time ODEs between measurements and undergoes discrete Kalman filter updates at measurement times. A belief-barrier-function-based safety checker enables segment-level probabilistic verification, detecting inter-sample chance-constraint violations missed by conventional node-based checks. The method is integrated with RRT and SST planners and evaluated on benchmark environments, showing high success rates and robust chance constraint enforcement, especially in narrow passages where discrete-time methods fail.

Sitting between a policy server and the physical hardware, it unifies the real-robot stages of the policy iteration loop within a single codebase. The framework features a component-decoupled architecture, inspectable execution workflows (Debug, Collect, Eval), and evaluation-as-data-collection, where each evaluation run produces training-ready trajectory data. It consolidates major real-time inference strategies behind a single configuration surface.
This systematic study introduces WMBench, a benchmark for evaluating world models as surrogate robot policy evaluators. Analyzing 7 video world models, 4 action schemes, and over 324,000 simulated rollouts paired with real robot executions, the authors identify three key insights: evaluator quality depends on long-horizon action-faithful consistency, pretraining requires balancing general knowledge with robot-specific controllability, and architectural choices critically determine alignment with real-world behavior. Based on these, they present GigaWorld-1, an optimized world model, and release all code, models, datasets, and toolkits.

DH-Active is a lightweight, training-free geometry back-end that uses LiDAR as a metric ruler to improve multi-view depth estimation. It anchors near-field returns via PnP, triangulates visual features, and selectively abstains in ill-conditioned regions.

This study proposes a two-stage U-Net framework for efficient prediction of time-averaged pedestrian-level wind speed over realistic urban morphologies. The model, trained on UrbanTALES dataset, uses a baseline U-Net (M1) for patch-wise prediction and a refinement U-Net (M2) based on inpainting to eliminate boundary artifacts. Results show reasonable reproduction of mean velocity and spatial variability, while maximum velocities remain underestimated. The framework offers an efficient surrogate for high-resolution pedestrian-level wind prediction.
This study presents a decision framework that quantifies the trade-off between labeling effort and recognition accuracy when transferring vision systems across marine habitats. The benchmark spans five datasets, three oceans, and three taxonomic groups. It finds that frozen self-supervised foundation features (DINOv2 + linear classifier) generalize well, requiring as few as 10-20 labeled images per species for reliable recognition at new sites, cutting annotation effort by roughly an order of magnitude.

Cross-lingual retrieval-augmented generation (RAG) often suffers from language drift and unreliable evidence use when evidence is in English. This paper proposes TR-RAG, a teacher-regularized RL method that combines reward optimization with on-policy distillation on student-visited prefixes, and introduces a reward decomposition, significantly improving language adherence and evidence-grounded correctness across multiple benchmarks.
LLMs can achieve high theoretical CBT knowledge (up to 96% on exams) but fail to apply it effectively in dialogue. A new metric (Protocol Leverage Force) shows that even with multiple chain-of-thought prompting, the effect on behavior is minimal (under 1.5%), and models remain biased toward validation and reflection.
This paper introduces PraMem, a method that constructs experiential memory by practicing on long historical sequences to address challenges in long-horizon behavior prediction with LLMs, achieving superior performance.

As LLMs are increasingly deployed as autonomous adjudicators in semi-open textual game environments, robust rule adherence becomes critical when user intent conflicts with system rules. However, these models are trained to be helpful and compliant, leaving them vulnerable to a class of attacks we term Rhetorical Injection, where adversarial users exploit narrative framing techniques such as pseudo-logical reasoning and authoritative coercion to bypass adjudication logic. We present CoC-Seduce, a multi-agent adversarial benchmark built on Tabletop Role-Playing Game (TRPG) mechanics, an ideal instantiation of semi-open environments where rules are explicit for adjudication, yet interaction remains entirely in natural language. Three frontier models, i.e., GPT-5.4, Claude Sonnet 4.6, Gemini 3.5 Flash, serve as adversarial generators producing 5,376 samples across 4 world settings and 16 skill categories. We then benchmark 20 target adjudicators against this corpus. Evaluation across 20 models reveals that neither model scale nor explicit reasoning mechanisms reliably confer adjudication robustness, with Pseudo-Logic emerging as the dominant attack vector and cross-cultural settings exposing systematic knowledge gaps across all evaluated families.
Gemma 4, the latest generation of open-weight, natively multimodal language models in the Gemma family, featuring dense and Mixture-of-Experts architectures ranging from 2.3B to 31B parameters. It includes improved vision/audio encoders, a unified encoder-free architecture for the 12B model, and a thinking mode that generates reasoning traces before responding. Enhancements in inference speed, memory efficiency, and long-context capabilities lead to strong performance on STEM, multimodal, and long-context benchmarks, rivaling larger frontier open models.
A new approach uses text-to-speech (TTS) to generate training data for Spoken Question Answering in Luxembourgish, a low-resource language. By translating existing text QA pairs, synthesizing speech, and training a parameter-efficient model with a frozen Whisper encoder and LoRA adapters, the method outperforms single-source TTS. Multi-source synthetic data and voice design improve performance, and no-reference TTS quality scores don't reliably predict QA accuracy.
