As we all know HTM implementation is biologically constrained. My intuition tells me that there are time nuances in regards to the reception of inputs in the cortex. To be more specific, if there are 5 bits going in, the 1st bit could be received before the 2nd bit, the 2nd bit could be the last and…

I like to think of the nerve signal as pulse trains so perhaps you could put this a bit differently: 1.x…x…x…x…x… (5) 2…x.x.x.x.x… (5) 3 .x…x…x…x…x…x…x. (7) 4 …xxxx.x…x…x…x…x… (9) 5 …x…x…x…x…x…x… (6) 1, 3 are first, 4 is the most sincere. 3 is among the first but not as intense as 4. That sa…

The time nuances is also the Temporal coding . It cannot be simply assumed that the temporal memory in the HTM is equal to the model of the temporal coding. Some analyses around the brain are from a physical perspective, such as waves and resonances. Before we figure it out, we can’t tell if they are…

I see what you mean and I can intuit that the TM is emulating/handling this nuance albeit in a very crude way. The reason I asked is because I’m experimenting with a highly concurrent system that somewhat mimics the SP but in a real-time manner. As in a region can recieve discrete input bits concur…

@Jose_Cueto , you say you run into a specific problem. Could you give an example of a real world situation? The example of @Bitking is really helpful to understand the problem. But it is an abstract set-up. We don’t know what these 5 spike streams represent. If they fire roughly together, there is g…

Let me try to describe my experiment. So I was experimenting with simulating an SP but with real-time properties. That is at least two processes run simultaneously. One process acts as a stream of input bits. These bits are streamed concurrently using internal asynchronous IO. Each bit in the strea…

Many synapses in the brain use Spike Timing Dependent Plasticity. It’s not implemented in HTM systems because the HTM simulates ~100 milliseconds at a time, which means that the exact timing information is not calculated.

I take a cut at it by having 4 phases of voting in hex-grid formation. [image] HTM Mini-Columns into Hexagonal Grids! Tangential Theories Ok - biological justification for a proposed learning rule: We have a stream of spikes coming at us from senses or a lower level. …

[image] Jose_Cueto: Another thing I’ve realized is that the SP algorithm is fully synchronous If you build it, the chips will come. Once we have chips like the ones RAIN Neuromorphics is working on, we’ll be able to parallelize all the processes.

[image] Jose_Cueto: is this really happening in the brain? I believe yes, so I asked another question why is it not implemented in HTM? There are all sorts of things reaĺly happening in the brain yes. And you can model each protein in synapses independently, but then my bet is you won’t imple…

I rambled a bit about this thread today on my live stream but I am not sure I have anything to add.
