KEEL - dataset     Unsupervised data sets

Unsupervised data sets represents a set of data whose examples have been not labeled. Thus, they can be employed by any kind of descriptive machine learning algorithm (e.g. associative rules, clustering, subgroup discovery...).

Each data file has the following structure:

  • @relation: Name of the data set
  • @attribute: Description of an attribute (one for each attribute)
  • @data: Starting tag of the data

The rest of the file contains all the examples belonging to the data set, expressed in comma sepparated values format.

KEEL - dataset

We offer information about experimental studies using these data sets (result files, papers and more) in the Experimental studies in unsupervised learning section of the repository.

Below you can find all the Unsupervised data sets available. For each data set, it is shown its name and its number of examples (instances) and attributes (the table details the number of Real/Integer/Nominal attributes in the data). In addition, the table shows if the corresponding data set has missing values or not.

The table allows to download each data set in KEEL format (inside a ZIP file). Additionally, we provide a header file to give additional information about each data set and its attributes.

By clicking in the column headers, you can order the table by names (alphabetically), by the number of examples or attributes, or by the presence of missing values. Clicking again will sort the rows in reverse order.
