Bases: prevision_quantum_nn.postprocessing.plotter.phase_space_plotter.PhaseSpacePlotter

Class PhaseSpacePlotter2D.

Plotter for a phase space of dimension 2

x_val

validation features to be plotted with the phase space

Type

numpy array

y_val

validation labels to be plotted with the phase space

Type

numpy array

x_plot

array of features to map the phase space

Type

numpy array

has_validation

tells if validation is set to on or not

Type

bool

set_validation_data(self, features, labels)

Sets validation data.

Parameters

• features (numpy array) – validation features to be plotted with the phase space

• labels (numpy array) – validation labels to be plotted with the phase space

Raises

ValueError if dimensions do not match 2 –

prepare_phase_space(self)

Prepare phase space of PhaseSpacePlotter2D.

Checks consistency of min and max creates xxp, yyp for drawing and x_plot for predicting

plot(self, model)

Plot the phase space of a model predictions

in 2D at current_iteration.

Parameters

• model (QuantumNeuralNetwork) – model to be used to plot phase space

• cuttent_iteration (int) – iteration at which the model is

• force_plot (bool) – if current iteration does not match verbose_period, you can also force the plot with this option set to True
