Memory representation in moth olfactory network, role of neuromodulators

This paper expands on that and provides some more
computational/mathematical interpretation:

Sanjoy Dasgupta, Charles F. Stevens, Saket Navlakha – A neural
algorithm for a fundamental computing
problem

key take aways

  • fly olfactory brain is an implementation of the HTM spatial pooler (my
    interpretation)
  • mathematically it’s an implementation of dimensionality reduction by
    random
    projections    ,
    relying on locality guarantees provided by the Johnson-Lindenstrauss
    lemma that I mentioned before

This is the regular reminder that we still need a mathematical model of
the whole thing, or in other words pull a Kepler on the Copernicus.
