Efficient Rollout Strategies for Bayesian Optimization

1 code implementation24 Feb 2020 Eric Hans Lee, David Eriksson, Bolong Cheng, Michael McCourt, David Bindel

Non-myopic acquisition functions consider the impact of the next $h$ function evaluations and are typically computed through rollout, in which $h$ steps of BO are simulated.

Sampling Humans for Optimizing Preferences in Coloring Artwork

no code implementations10 Jun 2019 Michael McCourt, Ian Dewancker

Many circumstances of practical importance have performance or success metrics which exist implicitly---in the eye of the beholder, so to speak.

Bayesian Optimization with Approximate Set Kernels

no code implementations23 May 2019 Jungtaek Kim, Michael McCourt, Tackgeun You, Saehoon Kim, Seungjin Choi

We propose a practical Bayesian optimization method over sets, to minimize a black-box function that takes a set as a single input.

Bayesian Optimization

Sequential Preference-Based Optimization

1 code implementation9 Jan 2018 Ian Dewancker, Jakob Bauer, Michael McCourt

Many real-world engineering problems rely on human preferences to guide their design and optimization.

Practical Bayesian optimization in the presence of outliers

no code implementations12 Dec 2017 Ruben Martinez-Cantin, Kevin Tee, Michael McCourt

In this paper, we present an empirical evaluation of Bayesian optimization methods in the presence of outliers.
