sklearn.base.BiclusterMixin

class sklearn.base.BiclusterMixin[source]

Mixin class for all bicluster estimators in scikit-learn

Attributes
biclusters_

Convenient way to get row and column indicators together.

Methods

get_indices(i)

Row and column indices of the i’th bicluster.

get_shape(i)

Shape of the i’th bicluster.

get_submatrix(i, data)

Return the submatrix corresponding to bicluster i.

property biclusters_

Convenient way to get row and column indicators together.

Returns the rows_ and columns_ members.

get_indices(i)[source]

Row and column indices of the i’th bicluster.

Only works if rows_ and columns_ attributes exist.

Parameters
iint

The index of the cluster.

Returns
row_indndarray, dtype=np.intp

Indices of rows in the dataset that belong to the bicluster.

col_indndarray, dtype=np.intp

Indices of columns in the dataset that belong to the bicluster.

get_shape(i)[source]

Shape of the i’th bicluster.

Parameters
iint

The index of the cluster.

Returns
shapetuple (int, int)

Number of rows and columns (resp.) in the bicluster.

get_submatrix(i, data)[source]

Return the submatrix corresponding to bicluster i.

Parameters
iint

The index of the cluster.

dataarray-like

The data.

Returns
submatrixndarray

The submatrix corresponding to bicluster i.

Notes

Works with sparse matrices. Only works if rows_ and columns_ attributes exist.
