hard_clustering_tuebingen

tangles.analysis.hard_clustering_tuebingen(tangle_matrix: ndarray, feat_ids: ndarray, feat_sys) → ndarray

Implements hard clustering as described in the Tuebingen Paper.

For each tangle, a corresponding cluster is calculated.

Parameters

tangle_matrixnp.ndarray

A (tangles x features)-matrix encoding whether a tangle contains a certain feature or its inverse. Contains 1 if the tangle contains the feature and otherwise 0.

feat_idsnp.ndarray

The feature ids corresponding to the columns of the tangle_matrix.

feat_sysFeatureSystem

A feature system.

Returns

np.ndarray

A (points x tangles)-matrix with values 0 and 1. For each point, it encodes the membership of the point to the cluster that corresponds to the tangle.
