SnAKe: Bayesian Optimization with Pathwise Exploration [article]

Jose Pablo Folch, Shiqiang Zhang, Robert M Lee, Behrang Shafei, David Walz, Calvin Tsay, Mark van der Wilk, Ruth Misener
2022 arXiv   pre-print
Bayesian Optimization is a very effective tool for optimizing expensive black-box functions.  ...  This paper investigates the problem and introduces 'Sequential Bayesian Optimization via Adaptive Connecting Samples' (SnAKe), which provides a solution by considering future queries and preemptively building  ...  Discussions with colleagues in the Imperial Department of Computing led to the ideas of -Point Deletion and the nonparametric -SnAKe.  ...

Slow and fast evolutionary rates in the history of lepidosaurs

Jorge A. Herrera‐Flores, Armin Elsler, Thomas L. Stubbs, Michael J. Benton, Roger Benson
2021 Palaeontology  
In a comparative phylogenetic study deploying Bayesian methods, we find that Squamata, comprising today over 10 000 species of lizards and snakes, showed slow rates of evolution in the first two-thirds  ...  Biodiversity today is uneven, with equally ancient sister groups containing few or many species.  ...  Here we explore an analogous case in Lepidosauria. The reptilian Superorder Lepidosauria includes the Rhynchocephalia (tuataras) and the Squamata (lizards, snakes and amphisbaenians).  ...
