As promised; neurons that establish a frame of reference to the room. Compare this to the research discussion about 3D reference, this is all about planar reference.
Travel constrained to paths, a common navigational context, demands knowledge of spatial relationships between routes, their components, and their positioning in the larger environment. During traversal of an environment composed of multiple...
These older threads discuss 3D coding - it’s 2D with “bending”:

Check out Matt Taylor’s superb Grid cells presentation in the HTM school!
Matt points out that thinking of grid cells as maps of a room vastly underestimates the general potential of mentally mapping any arbitrary 2D space.
Matt demonstrates the relationship between SDR representation and grid coding. I outline multiple methods of using HTM to form grids in this post. There are some pieces to put together but this combination represents a potential tool to code a reasonably intelligent agent.…

Live now building htm systems.
Also, please, please don’t house your devs with marketers!! This stresses out the dev and will also exacerbate any existing behavioral problems, or even add new ones as the marketer attempts to gain...

Live now , Let’s build Hot Gym in Python 3 with nupic.cpp!
Change of plans, now streaming a research meeting!
Live now for no real reason. Will stream until the research meeting at 10:10am.
So we skipped research today, sorry! But I’m streaming now talking about catastrophic forgetting https://www.twitch.tv/rhyolight_
Ok, there will be a live-stream of today’s research meeting, I just don’t know what time it will start. Stay tuned, I’ll post here.

A Hopfield network is a form of recurrent artificial neural network popularized by John Hopfield in 1982, but described earlier by Little in 1974. Hopfield nets serve as content-addressable ("associative") memory systems with binary threshold nodes. They are guaranteed to converge to a local minimum and, therefore, may converge to a false pattern (wrong local minimum) rather than the stored pattern (expected local minimum). Hopfield networks also provide a model for understanding human memo The u...

live now . Working on NAB python 3 and nupic.cpp python 3 today.
RE: your tablet twitch test.
BTW: I don’t think that apple phone is good for hangouts - I don’t think I looked or sounded very good on the last hangout.
