Hi @Caryn, thanks for posting. I’ve moved this into #nupic:developers because it is more of an advanced question about how to extend NuPIC classes.
I’m sorry to say that this project is quite a bit out of date. It uses an old version of our codebase. It is the CLAClassifier but we have changed that into the SDRClassifier.
What version of NuPIC are you running?
Also, a better example of this running on this data is in NAB. I think the same data set is used there as well, and it uses a more recent version of NuPIC.
