I’m in the middle of the Framework paper, and I won’t be able to finish it in time I’m afraid. (I’m a slow reader). However I have trouble understanding the displacement cells.
I understand how the displacement module represents a link between two objects or between two features. But how is this a displacement? Does that represent a vector (orientation + distance)? And if so, how big of a vector?
Imagine I know the Numenta logo, but I have never seen it on a cup. And I know a typical coffee cup, but I have never seen one with the Numenta logo on it. How would the displacement be determined to make this link? How would it be one down two to the right for instance? Would that displacement be related to one particular module of grid cells? Would it be defined the first time I anchor my grid cells to one of the objects?
Don’t get me wrong, the idea of having a logical link between features is mindboggling. But I feel I miss something essential to understand the full picture.
Edit: I think I just figured it out. Every feature of the cup has a displacement vector with every other feature of the cup, including every part of the logo on it. The more features my brain learns to identifie, the more displacement modules get defined.
This is profound… How on earth do you guys come up with this?
