This can be achieved by using the .get_units() and .cluster_ids() methods, which employ algorithms such as UMAP (McInnes et al., 2018) and HDBSCAN (McInnes et al., 2017). Afterwards, we can launch the interactive web app by calling .open_label_app(). Using this app, we can ...
The HDBSCAN algorithm was initialized with minimum samples equal to 10 and minimum cluster size equal to 200. The relative clustering validation procedure was run with 10 repetitions of 2-fold cross-validation, and number of random labeling iterations equal to 10. Because HDBSCAN does not need ...

Parameters --- dendrogram : array-like (size n_samples, 4) Dendrogram in Scipy hierarchy format min_cluster_size : int minimum number of children for a cluster to persist allow_single_cluster : bool whether or not to allow a single cluster in the face of mostly noise. cluster_selection_ep...
Parameters --- dendrogram : array-like (size n_samples, 4) Dendrogram in Scipy hierarchy format min_cluster_size : int minimum number of children for a cluster to persist allow_single_cluster : bool whether or not to allow a single cluster in the face of mostly noise. cluster_selection_ep...
Parameters --- clusterer : HDBSCAN A clustering object that has been fit to the data and had ``prediction_data=True`` set. batch_size : int, optional, default=min(4096, n_rows) Lowers memory requirement by computing distance-based membership in smaller batches of points in the training dat...
