8 Best Open-Source Tools for Data Mining

One of the popular terms in machine learning techniques is data mining. It is the process of extracting hidden or previously unknown and potentially useful information from the large sets of data. The outcome can be for analysing and achieving meaningful insights for the development of an organisation.  

In this article, we list down the eight best open-source data mining tools one must know.

6| Rattle

Written in R language, Rattle is a popular open-source GUI for data mining that presents statistical and visual summaries of data. It transforms data so that it can be readily modelled. It builds both unsupervised and supervised machine learning models from the data, presents the performance of models graphically, and scores new datasets for deployment into production.

Some of the features are-

  • It provides considerable data mining functionality by exposing the power of the R Statistical Software through a GUI
  • All of the interactions through the graphical user interface are captured as an R script that can be readily executed in R independently of the Rattle interface
  • The tool can be used to learn and develop skills in R and then to build initial models in Rattle
