MultiClassObjectiveFunction¶
- class MultiClassObjectiveFunction(X, y, neural_network, loss)[source]¶
Bases:
ObjectiveFunction
An objective function for multiclass representation of the output, e.g. classes of
0
,1
,2
, etc.- Parameters
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.
