Hi,
Congratulations on [HTM Studio!](http://numenta.com/htm-studio/) I’m **really** impressed with it! I found it fun and easy to use - kudos!
I got really excited when I saw something mentioned in your blog about a “Param Finder”, and I have a few questions:
1. Is HTM Studio open source?
2. Can the Param Finder source be shared? Could it be ported to HTM.Java?
3. To what degree is it or could it be a substitute for swarming?
Anyway, thanks for making such a cool HTM product. I can’t wait to promote it and use it as an example of things you can do with NuPIC!
Cheers,
David

Yes, you can see it here: [https://github.com/numenta/numenta-apps/tree/master/unicorn](https://github.com/numenta/numenta-apps/tree/master/unicorn)
@cmaver I think we should update [http://numenta.com/htm-studio](http://numenta.com/htm-studio) so that it says something about HTM Studio being open source and link to the repo.

[It is here](https://github.com/numenta/numenta-apps/blob/master/unicorn/py/unicorn_backend/param_finder.py) I think, and sure you can port it.

It is not a replacement for swarming, because it has a narrow use case. See here for detailed info:
[https://github.com/numenta/numenta-apps/blob/master/unicorn/py/unicorn\_backend/param\_finder.py#L184-L213](https://github.com/numenta/numenta-apps/blob/master/unicorn/py/unicorn_backend/param_finder.py#L184-L213)
Basically, it only works to find optimal aggregation and model params for one scalar stream of data (with a timestamp). I believe @ycui wrote this code, so he might have more to say.

Thanks @rhyolight and @cogmission.
Good suggestion. I will update the page to reference it being open source.

Thanks for the feedback @cogmission 🙂 @rhyolight’s answer is great. As he mentioned, it’s only a replacement for swarming if you have a single stream of scalar data. I will only add that if you are interested in porting the param finder, then you might want to look into: [https://github.com/numenta/numenta-apps/blob/master/unicorn/tests/py/integration/compatibility\_test/model\_runner\_2\_compatibility\_test.py](https://github.com/numenta/numenta-apps/blob/master/unicorn/tests/py/integration/compatibility_test/model_runner_2_compatibility_test.py)
It’s a compatibility test to ensure that we get comparable results on NAB data when using the NAB’s params or the params generated by the param finder. I think it’s a useful test to port as well, if you are thinking of porting param\_finder.py to HTM java.

You’re welcome. Thanks for pointing out the existence of that compatibility test. I believe that will come in handy if/when it becomes obvious that I’m going to port the param finder. For now my brain is NAB-fried… with butter on top! So I need a rest…
Anyway, great job on HTM Studio!

Cogmission, did you really port the Param Finder?
In case you didn’t do it yet , are you interested in doing it?
Could I help you in that case?
