Definition - What does Data Preprocessing mean? Data preprocessing is a data mining technique that involves transforming raw data into an understandable format. Real-world data is often incomplete, inconsistent, and/or lacking in certain behaviors or trends, and is likely to contain many errors. Data preprocessing is a proven method of resolving such issues. Data preprocessing prepares raw data for further processing.
The following guide is based WEKA version 3.4.1 Additional resources on WEKA, including sample data sets can be found from the official WEKA Web site. This example illustrates some of the basic data preprocessing operations that can be performed using WEKA. The sample data set used for this example, unless otherwise indicated, is the bank data available in comma-separated format (bank-data.csv). The data contains the following fields. In this example, we load the data set into WEKA, perform a series of operations using WEKA's attribute and discretization filters, and then perform association rule mining on the resulting data set.
