I was wondering if it is possible to generate uniformly distributed random numbers (in the range from 0 to 1) in a Nengo model? Just using one of the processes doesn't seem sufficient as the output will be filtered through the connection.
What for? You can turn off the filter on the connection.
That doesn't seem very biologically plausible to me and I need to persist the randomly generated number for some time. Another network will use that number to generate a choice.
One way would be to use a PresentInput process to present each number for a length of time. You could also write your own process.
