Second, you drag the imported data set to the process page, then search and find the operator menus in the operator sidebar, including Decision Tree, Apply Model, Split Data, and Performance. See also how to i mport data into the repository here -. RapidMiner is a software platform for data science teams that unites data prep, machine learning, and predictive model deployment. Then you import the data set into the rapidminer repository. Well, here's how to use the C4.5 algorithm.įirst, prepare your training data that meets the criteria for classification with the C4.5 algorithm. Where this is the latest update by Rapidminer itself. In this article I will share my educational experience regarding the implementation of the C4.5 algorithm using the RapidMiner Studio version 9.7 Beta application. You can download the driver from the Exasol Downloads portal. ![]() Whatever you prefer, RapidMiner has it all. Prerequisite Exasol JDBC driver installed on your operating system. Forget sifting through code You can also choose to run in batch mode. RapidMiner is easily the most powerful and intuitive graphical user interface for the design of analysis processes. How to create charts and graphs RapidMiner Studio Visualizing Data In RapidMiner 6:17 6:17 Presenting your results to others can best be achieved by creating charts and exporting them. The error that often occurs when using the C4.5 algorithm is that it does not determine the calculation criteria such as determining the value of the gain ratio, which is also very different from the ID3 algorithm and other decision tree families. rapidminer-studio-modular Public Easy-to-use visual environment for predictive analytics. See also the analysis and discussion in the article: Discussion of the C4.5 Algorithm. One of the calculation criteria performed by C4.5 is to determine the value of Entropy, Gain Ratio, and Split Info. It can also be used for model comparison and optimization. Auto Model - Classification Video Viewing time: 9m Guided classifications or rapid prototyping can be easily achieved with RapidMiner's Auto Model. The advanced charts are just briefly introduced, however, you can always refer to the respective guide for the full details. This video will show you how to use the basics and also the more advanced charts. This is also reinforced by the book by Santosa and Umam (2018) entitled "Data Mining and Big Data Analytics". Watch this video if you want RapidMiner Studio to do it all for you. Presenting your results to others can best be achieved by creating charts and exporting them. ![]() The development is intended to be able to overcome missing value attributes, be able to overcome continuous data attributes, and there is pruning of the already formed decision trees and the use of gain ratios as the solving criteria. Welcome to RapidMiner Studio, the easy-to-use visual environment for predictive analytics. The C4.5 algorithm is an algorithm developed from one of the methods, namely ID3, which is also included in the decision tree family.
