PREPROCESSING_DM

A Python module for data pre-processing of data-mining tasks

Quick start

$ git clone https://github.com/openbudgets/preprocessing_dm.git
$ cd preprocessing_dm
preprocessing_dm $ make init

Run test

preprocessing_dm $ make test

Generate documentation

preprocessing_dm $ ./make_docu

Documentation is located at docs/html/

Access PREPROCESSING_DM within iPython

$ iPython

In [1]: import preprocessing_dm as ppdm
In [2]: ppdm.get_all_observations_from_nonsliced_dataset("<http://data.openbudgets.eu/resource/dataset/aragon-expenditure-2010>")
