BinaryObjectiveFunction¶
- class BinaryObjectiveFunction(X, y, neural_network, loss)[source]¶
Bases:
ObjectiveFunction
An objective function for binary representation of the output. For instance, classes of
-1
and+1
.- Tham số:
X (
ndarray
) -- The input data.y (
ndarray
) -- The target values.neural_network (
NeuralNetwork
) -- An instance of an quantum neural network to be used by this objective function.loss (
Loss
) -- A target loss function to be used in training.
Methods
gradient
(weights)Computes gradients of this objective function given weights.
objective
(weights)Computes the value of this objective function given weights.
