MultiClassObjectiveFunction

class MultiClassObjectiveFunction(X, y, neural_network, loss)

Bases: qiskit_machine_learning.algorithms.objective_functions.ObjectiveFunction

An objective function for multiclass representation of the output, e.g. classes of 0, 1, 2, etc.

Parametreler

• 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.
