摘要: | We present a novel technique called probing cluster terrain (PCT) useful for exploring the terrain (shape and size) of individual clusters contained in input X = {x(i), i = 1,...,n}, even if X was not previously partitioned. A covariance matrix C-t(v(j)) is employed as an explorer to probe the terrain of the cluster centered at v(j). Associated with C-t(v(j)) is a ring formed with the formula for ... |
