 Data Mining Survivor: Weka - From University of Waikato
WEKA (the Waikato Environment for Knowledge Analysis) is an open source and freely available workbench for applying machine learning techniques to practical problems, integrating many different machine learning tools within a common framework and a uniform, if basic but functional, user interface.
WEKA incorporates over 60 machine learning techniques, ranging from traditional decision trees, association rules, clustering, through to modern random forests and support vector machines.
A WEKA user is able to use machine learning techniques to derive useful knowledge from quite large databases.

Clicking on the classifier tab after loading a dataset into Weka and selecting the choose tab will bring up a menu with a number of choices for the classifier that is to be applied to the dataset.
Another fact to keep in mind is that Weka gives hints on how to achieve the same result from the command line: look at what is displayed next to the Choose button and how it changes with the options that you select.
Weka also allows a user to select a URL as the source for a datafile (click on Open URL from the preprocess pane) or download data from a database (Open DB from the preprocess pane).

Wekas, or woodhens, are members of the rail family which are mainly aquatic birds, all capable of swimming well.
The Weka can raise up to four chicks a year and breed all year round if conditions are suitable and so it is not unusual to see a chick in the winter time or see a female with a juvenile and a chick in tow.

I wrote a backpropagation neural net classifier that is faster than the original Weka's NeuralNetwork, but compatible at the command line and gives exactly the same results if there are no missing attributes in the dataset.
The class is compatible with the latest version of Weka (3-3-4), which has many changes in package names when compared to previous versions.
A version compatible with Weka 3-2 (and other versions made available before the changes in package names) is available here.

The sample data set used for this example, unless otherwise indicated, is the bank data available in comma-separated format (bank-data.csv).
While the GUI version of WEKA is nice for visualizing the results and setting the parameters using forms, when it comes to building a classification (or predictions) model and then applying it to new instances, the most direct and flexible approach is to use the command line.

The instructions are designed for using Weka under Linux; as Weka is pure Java, feel free to do your work in a Windows environment instead.
The Prime Directive in machine learning is that, in order to measure anything useful about a learned classifer, the test data with which it is evaluated must be distinct from the training data from which it was generated.
In cross-validation (ie, invoking Weka with just the "-t" flag), Weka ensures that the training and test data are disjoint.

While WekaClassify was developed by Satanjeev Banerjee as a part of that package, we have found it generally useful and are distributing it separately as well, in the hopes that it will be useful for users of the machine learning suite Weka, regardless of their application area.
WekaClassify carries out classification based on a previously learned model by Weka, and produces output such that each possible answer is "scored" based on whatever criteria the learned model might use (confidence scores, probabilities, etc.).
This model has to be created by training some classifier (such as a decision tree, a neural network, a naive Bayesian classifier, etc) on training data consisting of instances of the same target word as that in the test arff file.
