y_pred is the predicted value, y_true is the true value, and delta is a hyperparameter that determines the threshold for switching between the MSE and MAE loss. When |y_pred - y_true| <= delta, the loss function is the MSE loss. When |y_pred - y_true| > delta, the loss function is the MAE loss with
