Hi,

I am wondering why the duration model is constructed with 5 dimensions
instead of 5 states. These might cause some differences in the
tree-based clustering.
Because they are highly correlated so we want to cluster them jointly.
In addition, can we reconstruct the duration
model into 5 states with 1 dimension readily by editing some configure
files?
No. If you want to construct a duration decision tree for each state position
separately, you can do it by modifying Config.pm like as follows:
@cmp = ('mgc','lf0');
- @dur = ('dur');
+ @dur = ('dur1','dur2','dur3','dur4','dur5');
$ref{'cmp'} = \@cmp;
%vflr = ('mgc' => '0.01', # variance floors
'lf0' => '0.01',
- 'dur' => '0.01');
+ 'dur1'=> '0.01);
...
I think HMGenS can work with this model, but I'm not sure whether hts_engine can
handle duration model with state-position-dependent decision trees or not.
