heavy-tailed

This paper frames model merging as probabilistic inference under a product-of-experts scenario, showing that existing methods are special cases and proposing a heavy-tailed Cauchy expert design that better captures real residual behavior, achieving significant improvements over state-of-the-art baselines.

TailedTS is a large-scale benchmark dataset derived from Wikipedia hourly page views, designed for evaluating time series models under heavy-tailed and non-Gaussian conditions. It includes a periodicity quantification framework and standardized prediction benchmarks using robust loss functions.
