class deephyper.ensemble.loss.Loss[source]#

Bases: ABC

Base class that represents the loss function of an ensemble.

Losses represent functions that should be minimized.

Methods

abstractmethod __call__(y_true: ndarray, y_pred: ndarray | Dict[str, ndarray]) → ndarray[source]#

Compute the loss function.

Parameters:

  • y_true (np.ndarray) – the true target values.

  • y_pred (np.ndarray or Dict[str, np.ndarray]) – the predicted target values.

Returns:

the loss value with first dimension n_samples.

Return type:

np.ndarray
