These datasets are useful to quickly illustrate the behavior of the various algorithms implemented in the scikit. They are however often too small to be representative of real world machine learning tasks. In addition to these built-in toy sample datasets, sklearn.datasets also provides utility functions for loading external datasets:

sklearn.datasets.fetch_20newsgroups_vectorized is a function which returns ready-to-use token counts features instead of file names.. 7.2.2.3. Filtering text for more realistic training¶. It is easy for a classifier to overfit on particular things that appear in the 20 Newsgroups data, such as newsgroup headers.

For ease of testing, sklearn provides some built-in datasets in sklearn.datasets module. For example, let's load Fisher's iris dataset: import sklearn.datasets iris_dataset = sklearn.datasets.load_iris () iris_dataset.keys () ['target_names', 'data', 'target', 'DESCR', 'feature_names'] You can read full description, names of features and names of classes ( target_names ).
