Does anyone know any good resource where example (real) data can be downloaded for experimenting statistics and machine learning techniques such as decision trees etc?
Currently I am studying machine learning techniques and it would be very helpful to me to have real data for evaluating the accuracy of various tools.
If anyone knows of any good resource (perhaps as csv, xls files or any other format) I would be very thankful for a suggestion.
The UCI Machine Learning Archive and the past datasets of the KDD Cup are probably the best known such archives for general data mining. An example of a more specific kind of source is the UCR Time Series Classification/Clustering Page.
