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…

Fooling Algorithms in Non-Stationary Bandits using Belief Inertia

arXiv:2511.05620v1 Announce Type: new Abstract: We study the problem of worst case regret in piecewise stationary multi armed bandits. While the minimax theory for stationary bandits is well established, understanding analogous limits in time-varying settings is challenging. Existing lower bounds…

Bayesian Network Structural Consensus via Greedy Min-Cut Analysis

arXiv:2504.00467v2 Announce Type: replace Abstract: This paper presents the Min-Cut Bayesian Network Consensus (MCBNC) algorithm, a greedy method for structural consensus of Bayesian Networks (BNs), with applications in federated learning and model aggregation. MCBNC prunes weak edges from an initial…
