Methods
-
activate(
N x) → N - The activation function.
-
activateEntry(
E entry) → E - The activation function for an entry (SIMD).
-
createRandomWeight(
Random random, {double? scale}) → double - Generates a random weight compatible with this activation function.
-
createRandomWeights(
Random random, int length, {double? scale}) → List< double> - Generates a List of random weights compatible with this activation function.
-
derivative(
N o) → N - The derivative function.
-
derivativeEntry(
E entry) → E - The derivative function for an entry (SIMD).
-
derivativeEntryWithFlatSpot(
E entry) → E -
The derivative function for an entry with
flat spot(SIMD). -
derivativeWithFlatSpot(
N o) → N -
The derivative function with
flat spot. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
