SharedWeightCF

SharedWeightCFProjection
A Projection with a single set of weights, shared by all units.

LeakyCFProjection
A projection that has a decay_rate parameter so that incoming input is decayed over time as x(t) = input + x(t-1)*exp(-decay_rate), and then the weighted sum of x(t) is calculated.

ScaledCFProjection
Allows scaling of activity based on a specified target average activity.

OneToOneProjection
A projection that has at most one input connection for each unit.
