Optimal Variable Weighting for Ultrametric and Additive Trees and K-means Partitioning: Methods and Software
... The optimization methods described above may sometimes produce a local instead of a global minimum of L U , L A , or L P . Hence, a good choice of initial weights is essential. While experimenting with our new program, ...
