pihnn.utils.PIHNNloss

pihnn.utils.PIHNNloss(boundary, model, t)

Evaluation of the loss function as Mean squared error (MSE).

Parameters:

• boundary (pihnn.geometries.boundary) – Domain boundary, needed to extract training and test points.

• model (pihnn.nn.PIHNN/pihnn.nn.DD_PIHNN) – Neural network model.

• t (str) – Option for ‘training’ or ‘test’.

Returns:

loss (float) - Computed loss.
