WebAs discussed in class, hierarchical clustering induces a partial ordering of the dendogram leaves (i.e., of the clustered items), modulo the 'flipping' of any of the sub-trees. However, one can obtain a total ordering by using the leaf-ordering algorithm developed by Bar-Joseph et al. (2001), which minimizes the distance betwees adjacent items ...
