What is the mechanism/algorithm for creating/destroying segments ? And the "attachment" of synapses ! Couldn't find explanation for this process in the docs. thanks -------| http://ifni.co On Thu, Dec 3, 2015 at 2:25 PM, Subutai Ahmad <[email protected]> wrote: > Roberto, > > This is not unexpected if you are feeding in random data all the time.
