I just had a thought, and its do with the hierarchy, and inference, and spacial 
pooling.
when you are inferring, you wind up, every symantic, a percentage error, coming 
up the proximals,you can use a threshold to instantly activate it at some 
error.    but wouldnt it be better, if you just passed up the error?   it works 
better this way, because then your smaller groups will work better, because 
they dont get stuck at an error minima.the later symantics can then 
"continuify" the error to a more exact quotient, by reading the error of the 
previous level, usingthe errors together to make a new error, which would have 
less error than the previous level, most of the time.
then you could keep passing the error till the last region, then have an exact 
"nearness" to the novel inputusing every single symantic together, leaving 
activation till later, making use of the distribution together.
notes about my system->Its purely spacial, with no temporal yet, that makes 
this idea much easier to do.  i also finish at a singlecollection, so all i 
have to do to inference is pick the cell of least error.  and it also has a 
separate inferencing stage from trainingso i dont know if this idea applies to 
htm,   but possibly could be useful to know.
