Parameter defaults in Proc HPForest

MartinBoland — Wed, 10 Oct 2018 04:59:00 GMT

Hi there,

Does anyone know if the parameter defaults differ between running proc hpforest in say, EG and running through the node in Enterprise Miner (EM)?

I have copied as many parameters as I can find from my EM project and run proc hpforest in EG but am not getting the same model produced.

Grateful for any advice.

Thanks,

Martin

If you run the following in your Project Start Code in Enterprise Miner:

options mprint;

then run the HP Forest node, you can see in the SAS log in the Results what exactly runs, for example running the node with defaults I get this using the HMEQ data:

MPRINT(HPDM_HPFOREST): proc hpforest data=EMWS18.Ids2_DATA alpha=0.05 catbins=30 exhaustive=5000 maxdepth=50 maxtrees=100 mincatsize=5 missing=USEINSEARCH minUseInSearch=1 seed=12345 trainfraction = 0.6 ;

MPRINT(HPDM_HPFOREST): / level = interval;

MPRINT(HPDM_HPFOREST): * for the ordering of target levels;
MPRINT(HPDM_HPFOREST): * if not ASC, FMTASC, or FMTDESC then alway use DESC;
MPRINT(HPDM_HPFOREST): target BAD / level =

MPRINT(HPDM_HPFOREST): PERFORMANCE DETAILS ;
MPRINT(HPDM_HPFOREST): run;
