Experiment with automated conversion to JavaScript

breznak commented 8 years ago

This issue relates to the #2 of the project. One option, even though definitely not the cleanest, would be to use an automated conversion tool to JavaScript from a source language (python, java).

the disadvantage: code will be a mess
advantage: low on resources, able to keep up-to-date with the main development (which is still active)
depending on interest in JS version development, and availability of man-hours, this could be a viable alternative to kick-start a HTM on JS for our applications.

We could port from:

python: the "main" development, https://www.quora.com/Is-there-a-way-to-convert-Python-code-into-JavaScript *java: http://www.gwtproject.org/overview.html

What do you guys think? @jefffohl @chessweb01 @mirkoklukas

For there to be a serious effort in making a new JavaScript implementation of HTM, I think there needs to be a compelling reason to do so. Ralf's project (this one), has the intent of being able to run HTM in a browser, for which, I suspect, he has his own reasons. I myself started a couple of JS implementations, but they have stalled out. I hope to get back to them at some point, but for me, the primary reason is for self-edification.

What are your reasons for wanting to implement HTM in JS?

Hi @breznak,

I'm not sure if you're aware of this, but this project is a direct port of htm.java to JavaScript? The last time I talked to Ralf, he was attempting to port over the Network API - which is where I believe he left off... But I think he's still around to answer your questions.

Cheers, David

@cogmission I know this was a port of htm.java but the last commit is dated some 8months ago, so a lot has changed. Would be great to hear from the main developer, the github nickname seems to be disabled..

@jefffohl I'm sure the port will be very demanding job, my motivation would be purely practical - I'd like to allow nupic.visualizer users have a built-in anomaly detection module (as HTM). For real hand-made porting I don't have the skills, nor enough interest. That's why I suggested the automated conversion (with all its drawbacks)

@breznak,

I would say, "a lot has been added" - but not much has changed (I re-wrote the TM for the whole orphan segments effort, but other than that almost everything else were additions). I would bet that the most viable alternative is to continue from where Ralf left off?

Yep, I just looked at it, and all you need to do is port over the Anomaly.java class and you're in business! :-) (if all you want is to run anomaly detection - you have the SP and TM and basic encoders...)

thanks for the review @cogmission ! That sounds pretty doable! :)
