Overview

About

Maintained by Novica NakovCRAN page ↗GitHub ↗Issues ↗

Fast, flexible framework for implementing Bayesian optimization of model hyperparameters according to the methods described in Snoek et al. (2012) doi:10.48550/arXiv.1206.2944. The package allows the user to run scoring function in parallel, save intermediary results, and tweak other aspects of the process to fully utilize the computing resources available to the user.

Changes in 1.3.0

New features

continue maintenance under new maintainer, point CI/CRAN metadata at fork (7dcae4b)

Bug fixes

fixed cran checks (766ba97)
migrate vignettes to Quarto; CI on GH Actions (9a289c4)
removed setorder apllied to local optim df which caused reproducibility-issues (10495b9)
test works (12bd3cb)
vignette builds (d5caef6)

ParBayesianOptimization 1.2.4

Changes

Fixed a small bug that allowed duplicates to make their way into the candidate table.

ParBayesianOptimization 1.2.3

Show all changes in 1.3.0Hide the rest of the changes in 1.3.0

Changes

Some suggested packages are now used conditionally in vignettes, reade, tests and examples since they might not be available on all checking machines.

ParBayesianOptimization 1.2.2

Changes

Removed Plotly from dependencies.

ParBayesianOptimization 1.2.1

Changes

Fixed a bug with initgrid on scoring functions with dimensionality over 4.

ParBayesianOptimization 1.2.0

Changes

Improved the way error handling works - any errors encountered in initialization will be returned.

ParBayesianOptimization 1.1.0

Changes

Changed Gaussian Process package to DiceKriging. predict method is much faster.

Added errorHandling parameter - bayesOpt() and addIterations() should now return results no matter what, unless errorHandling = 'stop'

Added otherHalting parameter.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("ParBayesianOptimization", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("novica/ParBayesianOptimization")

Development version from novica/ParBayesianOptimization. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-parbayesianoptimization

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ParBayesianOptimization

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-ParBayesianOptimization

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
