freedom of the linear model, which is similar to the VC dimension. It can be said that the role is consistent. As to why it is (D + 1/n), the author did not say it, and I am not clear about it... I feel that I am not very familiar with the following parts...
Why do we need to analyze the deviation and variance? The objective is to give a guideline to strike a balance between H, D, and learning algorithms.

repetitions, it is possible to calculate eval (h) to be able to utilize multiple data of the sample (K big).This makes it possible to achieve good predictive performance. Similar to the second lecture. Finally, we find the best performance model and use all the data to train again to get the final result.How do you choose the data from the sample during each training session? How many training sessions should be conducted before they can be completed?In general, the number of sessions = total s

Because then the margin will become infinitely large.The next task is to solve the above equation. The specific method can be referred to below.Finally, there are two issues to note:1, if the data is linearly non-divided.When the data is linearly non-divided, we can also use the above method, but will come to an unacceptable solution, at this time we can dete
