Report

For me, intrinsic and extrinsic motivation differs a lot. Since my early age, I distinguish clearly between schoolwork and extracurricular activities. During week days, I devote 100% of my energy into schoolwork and during weekends, I participate in robot and model aircraft clubs.
Before I entered college, I think that completing coursework is a student’s duty and it is also very rewarding. By behaving well in school, I can receive praise from my parents, respectation from peers, promising jobs and For this reason, completing schoolwork is mainly motivated by extrinsic rewards.

My dad used to have an argue with my mum about whether they should reward me by giving me some money to buy what I want if I perform well in exams. He thought exam scores should not be related with money rewards. While my mum thought it is reasonable since rewards can motivate me a lot. After I entered college, I thought my dad was right, although money rewards did motivate me to get higher scores, it is extrinsic motivation. According to the textbook, extrinsic rewards can reduce intrinsic motivation. When I look back, I cannot clearly figure out what is my intrinsic motivation of studying hard at school. Most of the time, I am motivated to study a subject just for the reason that I am good at it. If I am not good at a subject, such as Chinese, I just keep persuding me that if my Chinese is not learnt well, I will not be able to enter a good school. Usually, during this process, I suffer from heavy depression and anxiety. Speaking of how much passion I have in all of these subjects, I have to say, very little. My behaviour in exam-oriented education is like a machine. I get rewards, commitments as inputs and output good scores.

Although I behaves like the walking dead in schoolwork, I have intrinsic motivations in other fields, such as building robots and flying model aircraft. These activities fulfill no obvious purpose other than enjoyment.

Reference

• Les Choristes

Learning’s school of thoughts

Take the movie “Les Choristes” as an example

Behaviorism

Principals stand for Behaviorism:

In the face of confused or lost teenagers, the principal’s education method is very representative of the indifferent and rigid “behaviorist”. He believes that violence and punishment can make children keep their duties. The endless and varied punishment methods are his masterpieces. In the face of the principal’s violence, the children really behaved in silence and followed the rules, but they did not believe the principal from the bottom of their hearts. Once the principal leaves and doesn’t pay attention, the children will play tricks behind their backs and vent their emotions.

One of the core viewpoints of behaviorism is that environment is the only condition for the learning, and learning is completely determined by the external environment. Therefore, the principal puts the focus of education on corporal punishment, punishment, reprimand, and criticism. Even if children make small mistakes, they will always be scolded or beaten.

It is true that punishment as an external stimulus can promote children to develop in a good way to a certain extent, but the fear generated by punishment is often greater than the education gained, so children will become more and more disobedient, and they will not learn what they should know at all.

Non-associative

Habituation

Sensitization

Associative

Classical conditioning

When we learn that a stimulus predicts another stimulus.

Operant conditioning

When we learn that a behavior leads to a certain outcome.

Watching others

Observational learning

When we learn or change a behavior after watching a person engage in that behavior

Modeling

Displaying a behavior that imitates a previously observed behavior

Vicarious conditioning

learning about an
action’s consequences by observing others being rewarded or
punished for their behavior

Humanism

Mathews stands for Humanism:
Compared with the principal’s style, Teacher Matthew regards the children as himself, understands their distress, and walks into their hearts. Teacher Matthew is the first to really treat “problem teenagers” as dignified and thoughtful individuals. Teacher Matthew’s education and enlightenment are the classic characteristics of humanists.

Humanism holds that different people will have different beliefs about the same fact, which means different things to different people. Therefore, humanists can always start from the individual’s inner feelings and beliefs, and touch others with their feelings and ideas.

Teacher Matthew pays attention to discovering children’s potential in learning, and constantly encourages children to improve and cheer. Combined with rationality, it only helps children to affirm themselves and realize themselves.

A Message to Myself

hi, how are you doing today?
When you wake up in the morning to the sound of your alarm clock,
when you join an online lecture and hear the hissing sound coming from your headphones,
when the flying catkins take away the smell of heather,
you always wonder why you are here. living.
This is a hard question to answer, you are an atheist, you have to find out the answer that belongs to yourself.
The past 12 months have been very memorable for you, right?
You have changed from an unknown game player to a personal mod developer with over 10,000 subscribers in the steam workshop;
You become an video publisher in bilibili and your first video gets tens of thousands of views;
You have successfully established a blog site of your own;
Based on nvim, you have customized your own fancy editor;
You build a personal knowledge base with obsidian, and you feel your knowledge connected like never before;
You have gained an unforgettable internship experience and got your first salary in life;
You have led many scientific and technological innovation teams and met many people of all kinds;
You got to know chatGPT, which makes you feel that all the knowledge in this world is at your fingertips.

It looks like everything is going well, and you’ve been moving in a positive direction, but it’s superficial, and you still haven’t figured out what you’re living for.
You often boast that you have a good mentality and a big heart, but many times you are not strong psychologically, but numb to respond to stressors.
By now, you have come to the second half of your junior year. Compared with before, the pressure on your shoulders is even greater, especially the pressure of choosing your future path.
Under such pressure, it is easy to get lost if you don’t have clear enough pointers.
So, now is the time to seriously think about what you are seeking for in life. In general, it’s smarter to infer what you’re seeking from what you’re not gonna seek.
First of all, what you are seeking is not a fake, which can be defined as concealment, prevarication, hypocrisy.
For you, personal wealth, schooling certification are all fakes. They can only guide how others judge our worth, but they cannot tell us what our own worth is.

More fundamentally, You don’t pursue the approval of others, and you don’t pursue the society’s expectations of you.
You hate the studies of how to become success, you hate cram school, and you hate these things that are concretized by distorted human nature. You think that people should have some higher purpose.
But those purpose are too high, far beyond your reach, and the devil’s voice of corruption is always in your ears, and your pain comes from it.
In fact, at this point, you already understand what your life goal is, just say it, don’t care what other people will say, at least I won’t laugh at you.
You hope that one day you will contribute, in whatever form, to the advancement of all humanity.
Just like your favorite singer, Michael Jackson, you aspire to be a man who have a world in mind like him.
But now you are too far away from this goal, and you don’t even know how to touch it, but the pressure of life will always follow, and the prejudice of society will not disappear because of your denial.
For example, now, your road to postgraduate education is not clear, what should you do if you encounter various setbacks?
I think what you should do most is to reconcile with yourself. An outstanding person may not necessarily succeed, but he will definitely recognize himself.
Often, you don’t know where the next step will lead you, and you don’t want to put yourself in a bad situation again and again, but you have to remember that I am always by your side,
No matter what you do, no matter how bad things happen, I will always be there for you and I will always approve of you.
As long as the two of us are here, we will find a way to make things better. Because we’re best friends from now on, and that’s what best friends do.

I know a guy who compiled the obsidian version of the Chinese-English thesaurus by himself. He lost his job, got myeloma, and his health and wealth were shattered, but he completed this Grand project under such extremely difficult conditions.
I would like to quote a passage he wrote in his preface:
Now looking back, it all seems like a dream. If I wasn’t poor, I wouldn’t have had the time and energy to do this; if I was rich enough, I might have done something else; if my talent was a little bigger, I wouldn’t have done this; if my talent was a little smaller, it wouldn’t have been enough to do this; the highest level of computer language I know is the most basic HTML language, which can only change the color and style of text; if I hadn’t gotten sick, I wouldn’t have expanded my vocabulary to over nine thousand words; if there was no Bilibili and no video I made myself, my work would not have been known so quickly. All of these seem predetermined, not too much or too little, just right.

When you stumble again and again on the road of life, I will always reconcile with you, and we will face the next challenge with full confidence.

• 我曾经认可所谓的人本主义教育，作为我对于应试教育的反抗，但现在看来，他也是错的。
• 我担心我一辈子都活在一个乐于对人评头论足的环境
  • 对于一个人的学历
  • 对于一个人的选择
• 我担心我做的事情没有意义
  • 对于我的意义
    • 如果我在人生的最后，回过头来看，我是否会觉得我现在做的毫无意义？
  • 对他人来说的意义
    • 这个已经克服了，但不能完全忽视
    • 比如我的父母，他们在某种程度上就是30年后的我，他们的意见应该参考
• 我担心我对于太多事情有不切实际的期待
  • 对于人的本性（善/恶）
  • 对于人的欲望
  • 对于社会舆论
    • 当我认为他人生活在信息茧房中，我首先需要自指，我自己是否生活在茧房中？
    • 当我认为他人被洗脑时，我是否有被洗脑

Replace fear with confidence

Future is full of possibility

What is my confusion?

• 个人的努力在社会发展的洪流下不值一提

• 关于个人道路的选择

  • 读博士/读硕士
    • 博士？需要大量时间，家庭日渐凋敝，读出来后专业落伍
    • 硕士？内卷，名额太少，学术成就不如博士
    • 我追求学术成就吗？我认为这是在人类史上留下个人价值的最好方式。但我了解到了太多的科研劝退内容。
    • 所谓的劝退，针对的是对于科研抱有不切实际的期望的人群
      • 我属于那个人群吗
  • 学术成就/家财万贯（成功人士）/实业兴邦（打螺丝？）
    • 中产的美梦？
    • 家财万贯不现实，目前社会的上升通道太少，创业失败即家破人亡，ai或许能凿壁偷光？
    • 学术更像是一场赌博，稳妥的办法是添砖加瓦，但这已经有许多人在做了。但许多划时代的研究都不是如此。
    • 我目前的经历更主要偏向应用，调包，调参。。。。
    • 如果是应用，我希望我是构建者而不是码农
    • 什么是构建者？
      • 例如自研一些开发软件

• 我选择的信念是否正确？

  • 我的信念是什么？
    • 在更小时候，我并不喜欢他的音乐风格
    • 在高考那段最磨练意志的时段，主要是MJ的音乐陪我走过，给了我充沛的精神力量
    • 为什么我会喜欢MJ的音乐？抗争的精神力量！
      • 对于肤色的抗争
      • 对于政治迫害的抗争
      • 对于人类欲望的抗争
      • 对于病痛的抗争
    • 那么在高考那段时间，我到底想抗争什么？
      • 极端狭窄的独木桥
      • 对学生的评价体系
      • 压抑的同龄人氛围
      • 将人物化

df.groupby('column_name').agg(['sum', 'mean', 'max', 'min'])
df.groupby(['column_name_1', 'column_name_2']).agg({'column_name_3': ['sum', 'mean'], 'column_name_4': ['max', 'min']})
df.groupby(['column_name_1', 'column_name_2']).agg(['sum', 'mean', 'max', 'min'])

Example

Example 1

Extracting the top 20 categories from a DataFrame using groupby:

1. Use the groupby and size methods to calculate the size of each group:

   1 2 3 4 5 6 7

   group_sizes = df.groupby('category').size() ```` 2. Use the `sort_values` method to sort the group sizes in descending order: ```python sorted_groups = group_sizes.sort_values(ascending=False)

2. Use the head method to extract the top 20 categories:

1

top_20 = sorted_groups.head(20)

4. Use the isin method to filter the original DataFrame to only include rows with the top 20 categories:

1

df_filtered = df[df['category'].isin(top_20.index)]

This will extract the top 20 categories from the ‘category’ column of the DataFrame and create a new DataFrame that only includes rows with those categories.

Example

Example 1

Extracting room numbers from a ‘Description’ column in a DataFrame using regular expressions:

1. Import the re module:

   1 2 3 4 5 6 7 8 9 10 11 12

   import re ```` 2. Define a function to extract the room number from a description: ```python def extract_room_number(description): match = re.search(r'(\d+\.\d+|\d+)(?=\s+of which are bedrooms)', description) if match: return float(match.group(1)) else: return None

2. Use the apply() method to apply the function to the ‘Description’ column and create a new ‘RoomNumber’ column:

1

df['RoomNumber'] = df['Description'].apply(extract_room_number)

This will extract the room number from the ‘Description’ column and store it in the new ‘RoomNumber’ column.
