It took a little bit of a shock this week about the relationship between teachers taking classes and students attending classes. In fact, not all teachers practice the concept of "teacher, so preach, teach, and solve doubts" to treat every class and answer every question of students, so look at this problem from the perspective of students , Don't think that everything the teacher talks about is the latest, most valuable, and the most comprehensive, but you need to use a critical eye and curiosity to find out which tools are used to study what problems in related fields , the teacher may sometimes just introduce the most basic and ancient knowledge for us, let us know "Oh, there is such a thing in the original". For teachers who pour water heavily, they must learn to properly use their energy to focus on valuable things. "Training lies in the usual details. -- Dong L" If there is a task that must be completed but has no value, then look at it from a different angle and let it bring you some progress.
Closer to home, let's start summarizing the lessons.
1. Operating system principle: It mainly talks about the development history of the operating system, process management, etc.
2. Information analysis and prediction:
The four basic functions of information analysis and prediction are: sorting, evaluation, prediction and feedback. This week's main talk
Generation and development, development of information service industry, development trend and process of information analysis (similar to market research, etc.)
3. Information organization and information retrieval:
The teacher mainly let us do it ourselves, find problems and how to solve them during the retrieval process. In the retrieval system, users may not be able to accurately express their own needs, and it is also difficult for the system to accurately understand users' needs, which results in a gap between the retrieval results and user expectations.
In the specific retrieval process, you must first analyze, figure out where the content may appear, and then search for relevant fields.
4. Production operation management:
Frankly speaking, I didn't listen much at all, and the teacher even took a quiz at the end, which can be said to be caught off guard. (The teacher seems to upload the PPT in advance, so let's see it in advance, after all, the speed of reading is faster)
5. Market research methods:
The teacher is mainly talking about the topic selection, so it is better to determine what problem you want to study as soon as possible. What I think is quite rewarding is that the teacher mentioned some points to pay attention to about the paper: about the conclusion, it is often the part that people tend to ignore and "fuck", but this part is the most important, because the methods and data All can be obtained, but different people will come to different conclusions when they look at the same set of data . So when writing something, be sure to pay attention to analyzing the data, what phenomena and laws revealed by the model, and how to combine the previous theories to explain this result (the result is the general fact obtained after the experiment , and the conclusion is the point of view with your thoughts) , This result can provide what kind of basis for reality. At the same time, you should also pay attention to some shortcomings of your own experiments: within a certain error range, it shows what limitations exist (data or methods or models, etc.). Don't be anticlimactic, the latter is also the essence.
6. Game Theory:
Last time I wrote an assignment on game theory. Although I had a wrong idea at the beginning, after discussing it with my classmates, my ideas were clear and the process was smooth, and I thought it was quite interesting.
Although game theory involves mostly economic issues, those evidences can provide a good reference for our rational decision-making (life, all aspects of life), and I want to continue to study in depth.
7. Econometrics:
The measurement is still deriving some formulas, or you should find a book and read it yourself.
Overall, learning is my own business, and I still need to hurry up, take advantage of the fact that I have not yet set a general direction, dabble a lot, and build a more rational understanding of the world. Well... the world is so big, there are so many interesting things, I don't want to waste time on meaningless things.
