R package arulesCBA - Classification Based on Association Rules

The R package arulesCBA (Hahsler et al, 2020) is an extension of the package arules to perform association rule-based classification. The package provides the infrastructure for class association rules and implements associative classifiers based on the following algorithms:

• CBA: Classification Based on Association Rules (Liu et al, 1998).
• CMAR: Classification based on Multiple Association Rule (Li, Han and Pei, 2001) via LUCS-KDD Software Library.
• CPAR: Classification based on Predictive Association Rules (Yin and Han, 2003) via LUCS-KDD Software Library.
• C4.5: Rules extracted from a C4.5 decision tree (Quinlan, 1993) via J48 in R/Weka.
• FOIL: First-Order Inductive Learner (Yin and Han, 2003).
• PART: Rules from Partial Decision Trees (Frank and Witten, 1998) via R/Weka.
• PRM: Predictive Rule Mining (Yin and Han, 2003) via LUCS-KDD Software Library.
• RCAR: Regularized Class Association Rules using Logistic Regression (Azmi et al, 2019).
• RIPPER: Repeated Incremental Pruning to Produce Error Reduction (Cohen, 1995) via R/Weka.

The package also provides the infrastructure for associative classification (supervised discetization, mining class association rules (CARs)), and implements various association rule-based classification strategies (first match, majority voting, weighted voting, etc.).

Installation

Stable CRAN version: Install from within R with

install.packages("arulesCBA")
