Scalable Metropolis-Hastings for Exact Bayesian Inference with Large Datasets

1 code implementation28 Jan 2019 Robert Cornish, Paul Vanetti, Alexandre Bouchard-Côté, George Deligiannidis, Arnaud Doucet

Bayesian inference via standard Markov Chain Monte Carlo (MCMC) methods is too computationally intensive to handle large datasets, since the cost per step usually scales like $\Theta(n)$ in the number of data points $n$.

Towards a Testable Notion of Generalization for Generative Adversarial Networks

no code implementations ICLR 2018 Robert Cornish, Hongseok Yang, Frank Wood

We consider the question of how to assess generative adversarial networks, in particular with respect to whether or not they generalise beyond memorising the training data.

On Nesting Monte Carlo Estimators

no code implementations ICML 2018 Tom Rainforth, Robert Cornish, Hongseok Yang, Andrew Warrington, Frank Wood

Many problems in machine learning and statistics involve nested expectations and thus do not permit conventional Monte Carlo (MC) estimation.

Online Learning Rate Adaptation with Hypergradient Descent

3 code implementations ICLR 2018 Atilim Gunes Baydin, Robert Cornish, David Martinez Rubio, Mark Schmidt, Frank Wood

We introduce a general method for improving the convergence rate of gradient-based optimizers that is easy to implement and works well in practice.

On the Pitfalls of Nested Monte Carlo

no code implementations3 Dec 2016 Tom Rainforth, Robert Cornish, Hongseok Yang, Frank Wood

In this paper, we analyse the behaviour of nested Monte Carlo (NMC) schemes, for which classical convergence proofs are insufficient.
