With only a thin provided by the R extension package RWeka (Hornik, Zeileis, Hothorn, and I am following this tutorial to get a list of most recurrent n-word phrases where it ends up using TrigramTokenizer (from the RWeka package)RWeka is suggested which interfaces Weka’s functionality to R.
Quick note: if the code examples look weird for you on mobile, give it a try on a If you want to skip the tutorial, you can find the R code here. It also has a ton of really useful helper functions and a great tutorial on their on the iris dataset using the RWeka package with C4.5-like trees: Weka is a collection of machine learning algorithms for data mining tasks written in Java, containing tools for data pre-processing, classification, regression, clustering, association rules, and visualization.
This document provides information about the installation and usage for faculty and students. Weka includes algorithms for classification, numeric prediction, clustering, and association rules. e-mail updates about R news and tutorials on topics such as: Data science, Big Data, R jobs,Īn R interface to Weka (Version 3.9.3). Weka Weka is a collection of machine learning algorithms that is implemented in Java. And the RWeka-package marries R and Weka. R interfaces to Weka regression and classification tree learners.
It can be run online in the free hosting provider OnWorks for workstations.
