Overview

About

Maintained by Simon MuellerCRAN page ↗GitHub ↗Issues ↗

Case-based reasoning is a problem-solving methodology that involves solving a new problem by referring to the solution of a similar problem in a large set of previously solved problems. The key aspect of Case Based Reasoning is to determine the problem that "most closely" matches the new problem at hand. This is achieved by defining a family of distance functions and using these distance functions as parameters for local averaging regression estimates of the final result. The optimal distance function is chosen based on a specific error measure used in regression estimation. This approach allows for efficient problem-solving by leveraging past experiences and adapting solutions from similar cases. The underlying concept is inspired by the work of Dippon J. et al. (2002) doi:10.1016/S0167-9473(02)00058-0.

Changes in 0.4.1

Breaking changes

Redesigned API: snake_case function names (distance_random_forest, weighted_distance, terminal_nodes, as_dist_object). Old camelCase names still work but emit deprecation warnings.
R6 field names changed to snake_case (endpoint, dist_matrix, order_matrix). Old names emit deprecation warnings.
S3 generics added: predict(), print(), summary() for all model classes.

Bug fixes

Fix off-by-one error in terminal node IDs for RF depth distance.
Fix compilation on musl/Alpine Linux (no TBB fallback).
Fix platform-dependent test failure in ordering tests.
Replace broken URLs with stable DOI links.

Improvements

Improved vignettes: added set.seed() for reproducibility, tightened prose.
Removed archived pryr dependency; replaced with base do.call.
Removed data.table dependency.
Added CI/CD via GitHub Actions (macOS, Windows, Ubuntu).

From NEWS.md in the release

Install

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

install.packages("CaseBasedReasoning", 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("sipemu/case-based-reasoning")

Development version from sipemu/case-based-reasoning. 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-casebasedreasoning

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-CaseBasedReasoning

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-CaseBasedReasoning

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.
