AdaGeo: Adaptive Geometric Learning for Optimization and Sampling

AISTATS 2018poster

Gradient-based optimization and Markov Chain Monte Carlo sampling can be found at the heart of several machine learning methods. In high-dimensional settings, well-known issues such as slow-mixing, non-convexity and correlations can hinder the algorithms’ efficiency. In order to overcome these diffi…

Distribution of Gaussian Process Arc Lengths

AISTATS 2017poster

We present the first treatment of the arc length of the GP with more than a single output dimension. GPs are commonly used for tasks such as trajectory modelling, where path length is a crucial quantity of interest. Previously, only paths in one dimension have been considered, with no theoretical co…
