A PAC-Bayesian Perspective on the Interpolating Information Criterion

no code implementations13 Nov 2023 Liam Hodgkinson, Chris van der Heide, Robert Salomone, Fred Roosta, Michael W. Mahoney

Deep learning is renowned for its theory-practice gap, whereby principled theory typically fails to provide much beneficial guidance for implementation in practice.

Deep Generative Models, Synthetic Tabular Data, and Differential Privacy: An Overview and Synthesis

no code implementations28 Jul 2023 Conor Hassan, Robert Salomone, Kerrie Mengersen

This article provides a comprehensive synthesis of the recent developments in synthetic data generation via deep generative models, focusing on tabular datasets.

The Interpolating Information Criterion for Overparameterized Models

no code implementations15 Jul 2023 Liam Hodgkinson, Chris van der Heide, Robert Salomone, Fred Roosta, Michael W. Mahoney

The problem of model selection is considered for the setting of interpolating estimators, where the number of model parameters exceeds the size of the dataset.

Graph Neural Network-Based Anomaly Detection for River Network Systems

1 code implementation19 Apr 2023 Katie Buchhorn, Edgar Santos-Fernandez, Kerrie Mengersen, Robert Salomone

We further examine the strengths and weaknesses of this baseline approach, GDN, in comparison to other benchmarking methods on complex real-world river network data.

Transport Reversible Jump Proposals

1 code implementation22 Oct 2022 Laurence Davies, Robert Salomone, Matthew Sutton, Christopher Drovandi

Reversible jump Markov chain Monte Carlo (RJMCMC) proposals that achieve reasonable acceptance rates and mixing are notoriously difficult to design in most applications.

Continuously-Tempered PDMP Samplers

no code implementations19 May 2022 Matthew Sutton, Robert Salomone, Augustin Chevallier, Paul Fearnhead

We show how PDMPs, and particularly the Zig-Zag sampler, can be implemented to sample from such an extended distribution.

The reproducing Stein kernel approach for post-hoc corrected sampling

no code implementations25 Jan 2020 Liam Hodgkinson, Robert Salomone, Fred Roosta

Stein importance sampling is a widely applicable technique based on kernelized Stein discrepancy, which corrects the output of approximate sampling algorithms by reweighting the empirical distribution of the samples.

Implicit Langevin Algorithms for Sampling From Log-concave Densities

no code implementations29 Mar 2019 Liam Hodgkinson, Robert Salomone, Fred Roosta

Theoretical and algorithmic properties of the resulting sampling methods for $ \theta \in [0, 1] $ and a range of step sizes are established.
