Duration Aware Scheduling for ASR Serving Under Workload Drift

arXiv:2603.11273v1 Announce Type: new Abstract: Scheduling policies in large-scale Automatic Speech Recognition (ASR) serving pipelines play a key role in determining end-to-end (E2E) latency. Yet, widely used serving engines rely on first-come-first-served (FCFS) scheduling, which ignores variability in request duration…

Subliminal Signals in Preference Labels

arXiv:2603.01204v2 Announce Type: replace Abstract: As AI systems approach superhuman capabilities, scalable oversight increasingly relies on LLM-as-a-judge frameworks where models evaluate and guide each other’s training. A core assumption is that binary preference labels provide only semantic supervision about response…

Estimating Canopy Height at Scale

arXiv:2406.01076v2 Announce Type: replace-cross Abstract: We propose a framework for global-scale canopy height estimation based on satellite data. Our model leverages advanced data preprocessing techniques, resorts to a novel loss function designed to counter geolocation inaccuracies inherent in the ground-truth…

On the Theoretical Limitations of Embedding-Based Retrieval

arXiv:2508.21038v2 Announce Type: replace-cross Abstract: Vector embeddings have been tasked with an ever-increasing set of retrieval tasks over the years, with a nascent rise in using them for reasoning, instruction-following, coding, and more. These new benchmarks push embeddings to work…

HOG-Diff: Higher-Order Guided Diffusion for Graph Generation

arXiv:2502.04308v3 Announce Type: replace Abstract: Graph generation is a critical yet challenging task, as empirical analyses require a deep understanding of complex, non-Euclidean structures. Diffusion models have recently made significant advances in graph generation, but these models are typically adapted…

De novo molecular structure elucidation from mass spectra via flow matching

arXiv:2602.19912v2 Announce Type: replace Abstract: Mass spectrometry is a powerful and widely used tool for identifying molecular structures due to its sensitivity and ability to profile complex samples. However, translating spectra into full molecular structures is a difficult, under-defined inverse…

Cross-Resolution Attention Network for High-Resolution PM2.5 Prediction

arXiv:2603.11725v1 Announce Type: cross Abstract: Vision Transformers have achieved remarkable success in spatio-temporal prediction, but their scalability remains limited for ultra-high-resolution, continent-scale domains required in real-world environmental monitoring. A single European air-quality map at 1 km resolution comprises 29 million…

FlashMotion: Few-Step Controllable Video Generation with Trajectory Guidance

arXiv:2603.12146v1 Announce Type: cross Abstract: Recent advances in trajectory-controllable video generation have achieved remarkable progress. Previous methods mainly use adapter-based architectures for precise motion control along predefined trajectories. However, all these methods rely on a multi-step denoising process, leading to…
