Neuromorphic Architecture for the Hierarchical Temporal Memory

[Bitking]

H is for Hierarchy, but where is it?

Continuing the discussion from The art of SDRs: Some of you might be thinking… Hey, you call this stuff HTM but there’s no Hierarchy? What gives? The software architecture for hierarchies exists within both HTM.Java and NuPIC (and Comportex, right @floybix?). You can create models and link them together into a hierarchy, with lower levels passing data up into higher levels. The algorithmic mechanism for creating an effective learned spatiotemporal hierarchy using one layer of an HTM is sti…

Rethinking Hierarchy

I think the point we’re trying to make is this: objects are represented in all levels of the hierarchy. If you think of a coffee cup, you can imagine how it feels in your hands, against your lips. You can feel whether it is smooth or course. You also know it is a container used to transport liquid, usually into human mouths. This information is not present the lower sensory levels of the object’s representation, because they are focused on the small details, like textures or lines and curves. T…

Perhaps @rhyolight has more to add to this.
