Re: RapidMiner Data Modeling CHALLENGE - $100 prize

Here's what I would start with:

 

Impute Missing with k-nn optimization

Sliding Windown Validation

SVM with an RBF kernel

Optimize on Training/Testing widths, gamma, and C

Dear Scott,

 

i've tried to download your zip but i cannot open it. I always get errors. Any chance you could reupload it somewhere?

Yep, I'm also in the fifties with corrected validation oO

I'm curious if anyone comes up with something >60. Currenlty everything seems to level out at ~55...

I of course do not know what your preprocessing or your models look like, but I will say (as the only one who knows the data sets Smiley Happy ) that I was getting a boost in performance when I created attributes that split out the date: day of the week and month seemed to help, quarter did not.  Other tinkering with the dates may be helpful too...

and although it is likely you are doing something similar, creating lag series attributes helped as well.  Smiley Happy

Hey D,

very nice. I do have a model with 63% but on a different validation. The validation @sgenzer proposes takes how many steps? 500? Even with simple models it takes an hour for me. Are you sure on comm. training? This makes parameter tuning fairly hard.

 

Best,

Martin
