Pruning

Pruning(self, equation, proba=1.0)

Dataclass to represent a pruning condition for structural plasticity.

When the condition is true, a synapse is pruned with the specified probability.

PruningSynapse = ann.Synapse(
    parameters = dict(T = ann.Parameter(10000, 'global', int),
    equations = ann.Variable('''
        age = if pre.r * post.r > 0.0 : 
                0
            else :
                age + 1 : init = 0, int
    ''', init=0, type=int)
    pruning = ann.Pruning("age > T", proba = 0.5),
)

Parameters

Name	Type	Description	Default
equation	str	string representing the equation.	required
proba	float	probability of pruning of the synapse.	1.0
