HTM attention module #2648

Interesting thought of HTM, where SP's active columns get boosted from anomalous input, therefore creating a "short-term attention memory"

Doesn't boosting affect affinity for all previously seen patterns that are just beneath the connected threshold - globally without regard for; or biasing toward any particular pattern? Just wondering how the could act as an attention "focusing" mechanism?

Yes, that is boosting as the mechanism, but I've meant to boost (like a word) the synaptic input (or maybe slightly increase sensitivity even globally) for situations when "something unexpected happens". That leads to auto focus on "wrong" details, or higher sensitivity in risky situations. (or at least I believe so)
