[Kaldi-users] Repeated leaves in decision tree

[Yannis C. <ha...@ho...>]

Hello,
I am training a decision tree using the standard wsj/s5 recipe and I try to acquire its structure using GetTreeStructure().
However, I get a warning that there are repeated leaves in the tree , even though I have allowed clustering  (clustering threshold is a non-zero value, either -1 or a value greater that zero). Could this be a problem of the threshold value I use, given that I get the same warning using -1 as the clustering threshold? If not, how could I overcome this issue?
Furthermore, is there a way to get the initial tree given only the outcome of GetTreeStructureInternal() (parents of all nodes in the tree and EventMaps of all internal nodes) ?
I would like to thank you for the help,Yannis
