Thank you for your sharing and explanation! Indeed, Gradient Checking can effectively verify whether the gradient calculations in the backpropagation algorithm are correct.

For beginners, it is crucial to understand the processes of forward propagation, backpropagation, and gradient checking. The key points you mentioned—such as converting parameters and gradients into vector form for calculations, using small perturbations to approximate numerical gradients, and evaluating the reverse (comparing the differences between the two)—are essential for ensuring the correctness of the gradient computations.
Read MoreTheoretical Knowledge Points of "Improving Deep Neural Networks"
### Practical Deep Learning and Optimization - **Dataset Splitting**: A common split ratio is 98% for training, 1% for validation, and 1% for testing. Increasing data volume or applying regularization can improve model performance. Validation and test sets should be from the same distribution. Adjusting regularization parameters helps reduce overfitting. - **Optimization Algorithms**: Mini-batch gradient descent is faster than full batch processing; the ideal mini-batch size ranges between 1 and m. Exponential weighted averages are used to track data changes; learning rate decay techniques like \(0.95^t \alpha_0\) and \(\frac{\alpha_0}{\sqrt{t}}\) are effective. Adam combines the advantages of RMSProp with momentum. ### Hyper
