Strictly Constrained Generative Modeling via Split Augmented Langevin Sampling

arXiv:2505.18017v4 Announce Type: replace Abstract: Deep generative models hold great promise for representing complex physical systems, but their deployment is currently limited by the lack of guarantees on the physical plausibility of the generated outputs. Ensuring that known physical constraints…

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…
