In the morning, there was a traffic jam. I used my cell phone to read Lee Kai-fu's blog article. He said that during the interview with Microsoft Research Institute, he mainly asked several questions: first, whether you are smart, whether you can integrate into the team, and how you are qualified.
The questions include:1. "Why is the manhole cover circular ?"2. "estimate the number of gas stations in Beijing ".
The answer is as follows:

the VC dimension theory, we need more data to get the same generalization ability.For the second case, there is the same reason. We also inadvertently enlarged the size of the hypothesis set.can refer to Raymond Paul Mapa generalization theory (lesson six)There are two ways to resolve this:1, avoid data snooping. -_-2, can not avoid in the calculation of generalization theory when the data snooping into consideration. For example, consider increasing the complexity of the hypothesis set, increa

sessions should be conducted before they can be completed?In general, the number of sessions = total size of the sample/out-of-sample data. SizeHow many data should you choose to use as an out-of-sample data?The different requirements have different options, but one rule of thumb is:Out-of-sample data size = Total size of the sample/10.As to how the sample data should be selected, we can refer to the following methods:1, each time choose different data as the sample data, the data is not repeat
