摘要
Using quantization techniques, Laloe (2010) defined a new clustering algorithm called Alter. This L-1-based algorithm is shown to be convergent but suffers two major flaws. The number of clusters, K, must be supplied by the user and the computational cost is high. This article adapts the X-means algorithm (Pelleg & Moore, 2000) to solve both problems.
