CellScope.cs.findCenters

CellScope.cs. findCenters (rho : np.ndarray, delta : np.ndarray)

findCenters adaptively identifies multiple cluster centers based on the product of local density (rho) and the distance to the nearest higher-density cell (delta).

Parameters

• rho (ndarray):

  A vector of length n_cell, representing the local density for each cell.

• delta (ndarray):

  A vector of Euclidean distances between each cell and the nearest higher-density cell.

Return

• centers (ndarray):

  A vector containing the indices of the selected cluster centers, with the length equal to the number of centers.

• deltarho (ndarray | csr_matrix):

  A vector of length n_cell, representing the product of the normalized rho (local density) and delta (distance to higher-density cells).
