I am trying to better understand spatial pooling and am wanting to code up a working version of it on my own. I found two works (shown below) by Professor John Thornton in Australia as quite useful in this regard. I hope to implement these in time.
I had trouble keeping up with my overall schedule this week but I plan to finish it all up by tomorrow.
I got the Sine-wave Nupic example to run on my machine this week (see below).
But, I couldn’t get the Nupic code to compile on my machine. I wanted to be able to run their code on my machine and walk through the code step by step.
Particularly, I am keen on coding Spatial Pooler on my machine.
It was a long and stressful work week. I could not focus on NuPIC which was annoying. But, the contractors on Upwork told me that my mac system python has been removed and that is why NuPIC is not working properly. So I basically need to backup and restore my laptop. Not looking forward to doing this but I wont get a chance to work on this till the weekend.

I am still struggling to install NuPIC on my laptop. I had gotten it to work 3 times before and now something just seems off. I have tried everything from reinstalling python to xcode..relinking and unlinking. Below is the error I am getting
ld: library not found for -lpython2.7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command ‘clang++’ failed with exit status 1
I am so desperate for help now that I have put up a project on upwork.com to resolve this. The trouble is that I am not as well versed in command line syntax on my mac laptop. I have tried everything I can possible think of but even my experienced friends are unable to resolve it. So have to get some help.
On the more positive side, I have been keeping up with my reading schedule. I even got one fan for my blog.
I am trying to reinstall Nupic today and getting the sine-wave example to run. So haven’t had a much time to deliver anything.
As far as Nupic goes, I found this overview on youtube video by Rahul pretty good in terms explaining implementation details for Spatial and Temporal Pooler. I think once you have grasped the white paper, it’s good to go over this.
My goal is to implement encoder, spatial pooler, temporal pooler, CLA classifier.
I am getting this error in installing Nupic:
clang: error: invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later).
I have os 10.10.1, so am already updated.. not sure why i am getting this error.
