sklearn.datasets.make_checkerboard

sklearn.datasets.make_checkerboard(shape, n_clusters, *, noise=0.0, minval=10, maxval=100, shuffle=True, random_state=None)[source]

Generate an array with block checkerboard structure for biclustering.

Read more in the User Guide.

Parameters:
shapetuple of shape (n_rows, n_cols)

The shape of the result.

n_clustersint or array-like or shape (n_row_clusters, n_column_clusters)

The number of row and column clusters.

noisefloat, default=0.0

The standard deviation of the gaussian noise.

minvalfloat, default=10

Minimum value of a bicluster.

maxvalfloat, default=100

Maximum value of a bicluster.

shufflebool, default=True

Shuffle the samples.

random_stateint, RandomState instance or None, default=None

Determines random number generation for dataset creation. Pass an int for reproducible output across multiple function calls. See Glossary.

Returns:
Xndarray of shape shape

The generated array.

rowsndarray of shape (n_clusters, X.shape[0])

The indicators for cluster membership of each row.

colsndarray of shape (n_clusters, X.shape[1])

The indicators for cluster membership of each column.
