Advantages, Disadvantages and Applications of DBSCAN

WebPerform DBSCAN clustering from features, or distance matrix. X{array-like, sparse matrix} of shape (n_samples, n_features), or (n_samples, n_samples) Training instances to cluster, or distances between instances if metric='precomputed'. If a sparse matrix is provided, it will be converted into a sparse csr_matrix. WebThis implementation of OPTICS implements the original algorithm as described by Ankerst et al (1999). OPTICS is an ordering algorithm with methods to extract a clustering from the ordering. While using similar concepts as DBSCAN, for OPTICS eps is only an upper limit for the neighborhood size used to reduce computational complexity.
