abstract Loss.evaluate(predict, target)

An abstract method for evaluating the loss function. Inputs are expected in a shape of (N, *). Where N is a number of samples. Loss is computed for each sample individually.

パラメータ

• predict (ndarray) – an array of predicted values using the model.

• target (ndarray) – an array of the true values.

戻り値の型

ndarray

戻り値

An array with values of the loss function of the shape (N, 1).
