import weka.core.Instances;import weka.core.converters.ArffLoader;import weka.core.converters.CSVSaver;import java.io.File;
We have started with the ArffLoader class, and have created an object, loader, for it:
ArffLoader loader = new ArffLoader();
We have then assigned a filename, weather.arff, to the ArffLoader class, as seen in the following code:
loader.setSource(new File("weather.arff")); //Use the path where your file is saved.
We have also called the loader.setSource method and assigned a filename to it by using our File object. Once this is done, we will load this particular dataset ...
