crp_graph_2d

<p>: a matrix of data for clustering. Row is each data_i and column is dimensions of each data_i.</p>

data

<p>: an array denotes the number of a cluster for each data_i and it is the output of the method "crp_gibbs".</p>

z_result

Chinese restaurant process [Pitman (1995) <doi:10.1007/BF01213386>] is used in order to compose Dirichlet process [Ferguson (1973) <doi:10.1214/aos/1176342360>]. The clustering which uses Chinese restaurant process does not need to decide the number of clusters in advance. This algorithm automatically adjusts it. And this package calculates the ambiguity of clusters as entropy [Yngvason (1999) <doi:10.1016/S0370-1573(98)00082-9>].
