trace¶
Note
Memory traces are only implemented in the Stimulus-response learning and Guided associative learning mechanisms.
Specifies the decay factor of fading memory traces. The value is a number between 0 and 1. The higher value, the longer the memory trace of each stimulus stays with the subject. A low value means it fades fast. The default is 0.
The value of the parameter trace
is used in the decision function.
Syntax¶
trace = v
where v
is a scalar expression.
Description¶
trace = v
sets the decay factor to v
.
Examples¶
trace = 0.5
sets the decay factor to 0.5.
@variables x = 0.5
trace = x + 0.1
sets the decay factor to 0.6.
