Inefficiency of HTM topology from a ML standpoint

[Bitking]

There is some diffusion but it seems that topology is maintained through the levels of each sensory modality.

For the interested bystander, we hashed topology out in this thread:

Crazy quilting in the cortex

I am still digesting this paper but three things jump out that I have to relate now. Earlier work with stronger signals produced a more diffuse and geographically larger response. The important thing here is that the amplitude of the response is signaled by the size of the RF. This is important considering that the nerve response is essentially binary. It is not clear if this larger response uses the hex boundaries. The response is in both L2 and L4, and different types of cells in each layer…
