Which of the following statements is or are true regarding regularisation?多项选择题

A
Regularisation is a form of empirical risk minimisation.
B
Regularisation focuses on minimising the training error over everything else.
C
Regularisation is not necessary for neural networks because they have too many parameters.
D
Lasso and ridge regression add an additional function to be minimised during the training process, which represents the complexity of the model.
E
Regularisation attempts to minimise overfitting by finding a trade-off between predictive power and model simplicity.
