Share the current life -- a six week internship experience of a high school graduate in CCTV

         Hello everyone , Welcome to 《 Share your current life 》 The first phase . I am a beginner of artificial intelligence , Just graduated from high school .“ just ” It refers to this year 6 month 1 Number . Considering that the time you read this article may be in the distant future , So by the way ,“ This year, ” refer to 2022 year . My university 9 month 19 It's just the beginning of school , So I didn't know what to do for a long time . Because I want to go to university in England , Academic pressure is usually greater than that of domestic universities , I was thinking of graduating from high school with difficulty , The pressure of college is so great , You have to play crazy for three months before you go to college , At least we have to climb the legend of hearthstone to the top , But then I thought about it , If you spend all three months playing , I'm probably tired of playing games , At that time, you may be so bored that you won't bother to go online , So I still have to find something for myself . So I went to CCTV for an internship .

        This article will not cover any professional knowledge , Then because of the need of confidentiality , It will not involve anything about the internal work of CCTV , Only my experience and feelings . Everyone should listen to me tell a story , Or just read a novel .

About my internship in CCTV for six weeks

        I am from 6 month 14 I started my internship on Tuesday afternoon , Until 7 month 22 On Friday, , It's a total of six weeks, one day short .

1. First week

        CCTV is located in the East Third Ring Road of Beijing , It's about an hour's journey from home, whether by car or by subway . The first time I went there was by car , Then I began to panic for an hour on the road . Why panic ？ Would you , I'm just an ordinary high school student , My knowledge 、 They are all very shallow , No working experience , I've never seen the working scene and state of programmers at all , But suddenly I have to go to such a big place as CCTV for internship , This contrast gives me a huge and indescribable sense of oppression . If you insist on describing , I probably slept in class 10 Minute sleep again 29 Minutes after the hearthstone , When the teacher called you to the office one minute before class , The tension of the unknown and the fear of the upcoming trial . This led me to spend the whole hour in my brain to make up for all kinds of possible terrorist situations after I got there , For example, what should I do when people dislike me 、 How can I talk to someone when everyone ignores me 、 What should I do when everyone is unwilling to hand over the task to me . In addition, I keep thinking about what programmers in TV stations are like , Is it like the hacker in the movie who doesn't say a word , Frown tight , A program can be completed instantly by tapping randomly on the command line ？ If so , Is it like a primitive person for them that I am there ？

        In short, I spent an hour in such a hurry , As soon as I looked up, I had reached the East Third Ring Road . I noticed that there are so many high-rise buildings in the East Third Ring Road , In addition to the bizarre CCTV and the Chinese statue next to it, which is much taller than the TV station , There are also a lot of buildings that I can't name . But I'm definitely not in the mood to see the scenery at all .

        Everyone should have heard about the shape of CCTV , It's just a pair of big underpants . But although the TV station is a strange place , The road inside is not hard to find , Because there is only one main corridor on each floor . My internship position is 40 Multi-storey , Walk through the hall on the first floor, about 5 Minute time .

        I spent most of my internship watching and learning , Because as a high school student, I'm really not good at knowledge and work experience . This is almost what I expected , I am also very satisfied , After all, no matter what way , As long as you can learn something .

        The first week is mainly about getting familiar with the working environment . After staying here for an afternoon, I found , It turns out that the working state of programmers is completely different from what I imagined , At least the programmers of TV stations are like this . They used to be like me when they wrote code , You have to stare at the screen for a long time before you can write a sentence . They haven't been writing hard , Also occasionally touch fish , Look at strange articles , Play games and so on . And the most important thing is , The programmers here are really very, very friendly , Everyone is very, very friendly .

        After a brief understanding of the working environment , I began to do my own work . I am mainly engaged in some natural language processing related things in TV stations . But because I'm just a beginner of artificial intelligence , So there are many things to learn now . As for what I learned , You can see mine 《 Share what you learned this week 》 That column . The third column N This article corresponds to the... Of my internship N+1 What I learned last week , Because I didn't learn anything in the first week . I won't go into details about what I learned every week , I will only mention , Friends who want to know more can subscribe to my column . Share what you learned this week https://blog.csdn.net/weixin_48978134/category_11884423.html?spm=1001.2014.3001.5482        Then the first week is to do a voice classification practice （ Using a convolutional neural network model CNN14）. You don't need to know what these mean , Anyway, it's not a difficult task .

2. The second week

         From this week on , I have basically adapted to the life of coming to practice every day , Finally, I can feel the mood from the TV station 40 The window of the multi-storey building looks into the distance , Overlooking the rows of tall buildings next to the East Third Ring Road 、 The solemn and magnificent buildings along Chang'an Street and the magnificent scenery of the whole Beijing city . From here you can clearly （ If your eyesight is as good as mine ） See the golden roof of the Forbidden City , The national Expo and the Great Hall of the people , And the bustling vehicles on Gulou Street .

        My main gain this week is to GitHub and Gitee Understanding of these open source websites . My knowledge of these websites ranges from “ A website used to copy the code of big guys ” Turned into “ Used to store your own code 、 A website that manages its own projects and copies the codes of big guys ”, So I am Gitee Created its first warehouse on , Put some things you wrote on it . Looking at the green dot on my home page seems to be really fulfilling .

        I started blogging this week , And I also plan to keep blogging every week as a habit , Because I can really feel it after I finish writing , It is very meaningful to spread the knowledge you have learned , And it can consolidate knowledge and exercise your expression ability very much .

3. The third week

        I attended a meeting on TV this week . As for the specific content of the meeting, it is certainly inconvenient to write it out , But roughly describe two departments for one AI There was a quarrel about the parameter setting of . Why is it noisy ？ Is probably ：

import random


class A:

    def __init__(self):
        self.viewpoint = "Less parameters"
        self.reasons = ["no money", "no GPU", "you are stupid"]

    def __str__(self) -> str:
        reason = random.choice(self.reasons)
        return f"A: We think {self.viewpoint} because {reason}."


class B:

    def __init__(self):
        self.viewpoint = "More parameters"
        self.reasons = ["good performerce", "good accuracy", "you are stupid"]

    def __str__(self) -> str:
        reason = random.choice(self.reasons)
        return f"B: We think {self.viewpoint} because {reason}."


a = A()
b = B()
while True:
    print(a)
    print(b)
    print()

        The adult translation is , People in my Department say ：“ The parameter quantity cannot be too much , Because we GPU Not enough performance ！” Then the other department said ：“ More parameters , Otherwise, the effect will not work ！” Then both sides will say their own , Enough to say 20 minute . Let's take a look at the output ：

        I was bored when I listened there , Can't you do a small-scale experiment by yourself , See how much lower the performance will be compared with the number of low parameters and high parameters 、 How much will it cost , I have to fight here for so long . Finally, the solution reached at the meeting is indeed to use small-scale experiments to evaluate . alas , It seems that the communication efficiency of large units is not necessarily high .

4. Fourth ~ Six weeks

        On the fourth week, I watched the 6th world intelligence conference media Intelligence Summit Forum . After watching the , I feel it for countless times AI The wide range of uses 、 The power of performance .

        The forum mainly talks about AI The application of technology in the media industry , It may not have much to do with you , But it is recommended that you also take a look at this forum . Media Intelligence Summit Forum https://2022.wicongress.org.cn/zh/introduce/introduceDetails/6295dc18624cd8018d616be5

        There are two weeks left to do nothing special , I won't go into details .

        I never like to sum up after doing something , However, for a blog that shares personal experience, it may seem a little strange not to summarize . In general , The harvest of this internship can be said to be very big , After all, it is a high school student who has never seen the world that first came into contact with a real working environment . In addition, I also learned a lot of knowledge and ways to understand knowledge 、 Method . Six meaningful weeks , The degree of significance is second only to the legend of the summit hearthstone .
