An MLCommons Scientific Benchmarks Ontology

arXiv:2511.05614v1 Announce Type: new Abstract: Scientific machine learning research spans diverse domains and data modalities, yet existing benchmark efforts remain siloed and lack standardization. This makes novel and transformative applications of machine learning to critical scientific use-cases more fragmented and…

Language Generation with Infinite Contamination

arXiv:2511.07417v1 Announce Type: cross Abstract: We study language generation in the limit, where an algorithm observes an adversarial enumeration of strings from an unknown target language $K$ and must eventually generate new, unseen strings from $K$. Kleinberg and Mullainathan [KM24]…

Frequency Matters: When Time Series Foundation Models Fail Under Spectral Shift

arXiv:2511.05619v1 Announce Type: new Abstract: Time series foundation models (TSFMs) have shown strong results on public benchmarks, prompting comparisons to a “BERT moment” for time series. Their effectiveness in industrial settings, however, remains uncertain. We examine why TSFMs often struggle…
