Constrained Bayesian optimization for automatic chemical design using variational autoencoders

RR Griffiths, JM Hernández-Lobato - Chemical science, 2020 - pubs.rsc.org
Automatic Chemical Design is a framework for generating novel molecules with optimized
properties. The original scheme, featuring Bayesian optimization over the latent space of a …

Dealing with categorical and integer-valued variables in bayesian optimization with gaussian processes

EC Garrido-Merchán, D Hernández-Lobato - Neurocomputing, 2020 - Elsevier
Some optimization problems are characterized by an objective that is very expensive, that
lacks an analytical expression, and whose evaluations can be contaminated by noise …

On nesting monte carlo estimators

T Rainforth, R Cornish, H Yang… - International …, 2018 - proceedings.mlr.press
Many problems in machine learning and statistics involve nested expectations and thus do
not permit conventional Monte Carlo (MC) estimation. For such problems, one must nest …

Automating inference, learning, and design using probabilistic programming

T Rainforth - 2017 - ora.ox.ac.uk
Imagine a world where computational simulations can be inverted as easily as running them
forwards, where data can be used to refine models automatically, and where the only …

Bayesian optimization for dynamic problems

FM Nyikosa, MA Osborne, SJ Roberts - arXiv preprint arXiv:1803.03432, 2018 - arxiv.org
We propose practical extensions to Bayesian optimization for solving dynamic problems. We
model dynamic objective functions using spatiotemporal Gaussian process priors which …

Fourier feature approximations for periodic kernels in time-series modelling

A Tompkins, F Ramos - Proceedings of the AAAI Conference on …, 2018 - ojs.aaai.org
Abstract Gaussian Processes (GPs) provide an extremely powerful mechanism to model a
variety of problems but incur an O (N 3) complexity in the number of data samples. Common …

Variational Inference with Sequential Sample-Average Approximations

H Zimmermann, CA Naesseth… - arXiv preprint arXiv …, 2024 - arxiv.org
We present variational inference with sequential sample-average approximation (VISA), a
method for approximate inference in computationally intensive models, such as those based …

Nesting probabilistic programs

T Rainforth - arXiv preprint arXiv:1803.06328, 2018 - arxiv.org
We formalize the notion of nesting probabilistic programming queries and investigate the
resulting statistical implications. We demonstrate that while query nesting allows the …

[PDF][PDF] The DARC Toolbox: automated, flexible, and efficient delayed and risky choice experiments using Bayesian adaptive design

BT Vincent, T Rainforth - PsyArXiv. October, 2017 - robots.ox.ac.uk
Delayed and risky choice (DARC) experiments are a cornerstone of research in psychology,
behavioural economics and neuroeconomics. By collecting an agent's preferences between …

[HTML][HTML] Exact stochastic constraint optimisation with applications in network analysis

ALD Latour, B Babaki, D Fokkinga, M Anastacio… - Artificial Intelligence, 2022 - Elsevier
We present an extensive study of methods for exactly solving stochastic constraint
