There were two group meetings at the beginning of school, and I was nervous and nervous each time. In addition, the instructor was not the kind that was very kind, so I was a little afraid to start group meetings, but it was indeed lack of experience. It's really not done well, and I didn't say it well when I said it. The instructor will stare at the ppt and keep asking questions, which is more nervous.
When doing ppt, including doing pre, you need to think about the problem from the perspective of the audience and explain the problem in a simple way. When explaining the paper, you should start with the macro and then the micro, top-down, and look at the problem from a relatively high angle. At the very beginning, we must make it clear what this paper is for.
- What problem is the paper to solve. Why did the author write such a paper and what was the motivation behind it.
- Where did the idea of the paper come from. The core idea of a paper is only a small one or two, so how did the author think of it, and what kind of discovery the idea was based on
- What is the idea of the paper. That is, what the paper did, what was the central idea of this paper, and what kind of work was done.
- What is the approach of the paper. After sorting out the previous points, what is the specific implementation method. For the audience, after listening to the previous points, he should form a general outline and then the specific implementation details.
In summary, first let the audience have a more macro understanding, and then go to the details. When doing pre, you must follow these guidelines. Otherwise, you will explain the details of a large number of algorithm implementations at the beginning, and the audience will hear it. , The final result may be that the details are understood, but the audience does not understand why this is done.
In fact, it is the same when learning. You must first understand the macro level, and then get involved in the details, learning from the top down.
