Named after a flightless new zealand bird, weka is a set of machine learning algorithms that can be applied to a data set directly, or called from your own java code weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualisation. Below are some sample datasets that have been used with auto-wekaeach zip has two files, testarff and trainarff in weka's native format to use these zip files with auto-weka, you need to pass them to an instancegenerator that will split them up into different subsets to allow for processes like cross-validation. What is weka weka is a collection of machine learning algorithms for data mining tasks the algorithms can either be applied directly to a dataset or called from your own java code. The iris dataset a very common dataset to test algorithms with is the iris datasetthe following explains how to build a neural network from the command line, programmatically in java and in the weka workbench gui.

It is a good idea to have small well understood datasets when getting started in machine learning and learning a new tool the weka machine learning workbench provides a directory of small well understood datasets in the installed directory in this post you will discover some of these small well. The dataset format that's used throughout azure machine learning the arff format that's used by weka weka is an open-source java-based set of machine learning algorithms. Depending on your installation of weka, you may or may not have some default datasets in your weka installation directory under the data/ subdirectory these default datasets distributed with weka are in the arff format and have the arff file extension. Classic datasets like iris are available with weka distribution in the folder 'data' so starting to explore weka's classification algorithms is easy with the data sets provided.

Weka instructions overview weka is a data mining suite that is open source and is available free of charge if you want to be able to change the source code for the algorithms, weka is a good tool to use. Introduction to weka- a toolkit for machine learning winter school on data mining techniques and tools for knowledge discovery in agricultural datasets . The wekafilters package is concerned with classes that transforms datasets -- by removing or adding attributes, resampling the dataset, removing examples and so on this package offers useful support for data preprocessing.

  • Dataset 3in weka, for this dataset we obtain three classes then we have 3x3 confusion matrix the number of correctly classified instances is the sum of diagonals in.

This tells weka that to build our desired model, we can simply use the data set we supplied in our arff file finally, the last step to creating our model is to choose the dependent variable (the column we are looking to predict.
