Later, Lin Chaoxi recalled this period of life, which was probably the most difficult time in her life, but she was not afraid at all at that time.
The intensive training has entered a white-hot stage. Although the examination is brutal, it also clearly reflects personal ability.
Unable to use physical discomfort or other excuses, Lin Chaoxi realized very clearly that her abstract thinking and spatial imagination abilities were indeed not as good as A Guang's.
After overcoming her previous self-doubt, she became calm instead.
A Guang was firmly at the top of the class, and Lao Wang and Shizi's grades were also steadily improving. Sometimes, Lin Chaoxi would hear them talking about number theory together, but the depth of their discussion went beyond elementary number theory; they really loved math.
I have to say that William Chang’s eye for selecting students is still very sharp, but his emotional intelligence may be as low as he is.
A Guang can concentrate on mathematics, but he is crazy and does whatever he wants with everything else.
After Lin Chaoxi failed A Guang's test three times, he was blocked by the little bald guy when he walked out of the toilet after class.
"Hahahaha Lin Chaoxi, why can't you test better than me now?"
Ah Guang was waving the test paper in his hand, and no one knew what he was happy about.
There were college students and students from their training team around, and most of them looked like they were enjoying the show.
Lin Zhaoxi stared at the test paper in A Guang's hand and asked hesitantly, "Did you wash your hands after going to the toilet?"
Ah Guang's eyes widened immediately: "I...I...I forgot!"
"I'll hold the test paper for you, go wash your hands." Lin Zhaoxi stretched out her hand, and A Guang quickly handed the test paper to her, "You are not allowed to throw my test paper into the toilet!"
"I'm not you."
The sound of water splashing came from the men's toilet. Lin Chaoxi opened A Guang's test paper, leaned against the door of the men's toilet, and watched him solve the problem carefully.
The students who had enjoyed the show looked at each other in wide eyes and dispersed with bored looks on their faces.
When A Guang came out, everyone had left.
"So, am I a super genius?" His happy laughter echoed in the quiet corridor.
"Yes." Lin Zhaoxi said, "The solution to the third question is very beautiful. I didn't think of this idea."
Ah Guang approached her and examined her carefully.
"What's wrong?"
"You're so scary, why don't you cry?"
"I'll just try hard to surpass you next time. What's there to cry about?" Lin Chaoxi smiled.
——
But in fact, she still cried a little.
During those days, when she was doing simple programming, the program always behaved abnormally.
She would always calm herself down and spend most of her lunch break correcting the errors, only to find that they were all minor problems stemming from her unfamiliarity with the programming language.
She was very sure that if she searched the problem on Baidu in seven years, she would be able to quickly find the cause of the error, but now, she had to spend several times more time analyzing it herself.
This analysis wasn't a bad thing, but she still felt a little anxious about the waste of time.
She really wanted to go back.
Especially when studying linear models, she saw a familiar term - Fisher linear discriminant.
Fisher discriminant analysis reduces the dimension of the data and projects it onto a straight line, making the same category as close as possible and the different categories as far as possible.
In the binary classification task, the two types of data satisfy the Gaussian distribution and have the same variance, and linear discriminant analysis produces the Bayesian optimal classifier.
The terms that seemed completely incomprehensible to me at the time actually became clear to me after I understood a series of concepts.
Lin Zhaoxi picked up a pen and wrote down the question that Pei Zhi had asked on the blackboard that day. He felt relieved, but did not answer it.
——
It is almost mid-August and the training team is about to face the final assessment.
In the morning, she was eating milk and eggs in the cafeteria. When she was about to put the remaining half of a steamed bun into her lunch box, a red hundred-dollar bill suddenly appeared in front of her.
Looking up, Liu Zhiyuan was standing in front of her desk with a dark face.
There weren't many people in the cafeteria, but there were still a few tables of students from the training team sitting around.
Lin Zhaoxi frowned: "What for?"
"Take the money and have a good meal."
"I don't need your money."
"Do you still want to say that your family is rich? Eat one steamed bun in two meals. Girls, stop trying to be so stubborn."
There were people pointing and laughing all around. Lin Chaoxi was stunned.
"Ah, Lin Zhaoxi, just accept it."
"Can't you see that Liu Zhiyuan has liked you for so long?"
"No matter how hard it is to study, it's better to be the young lady of our Liu family!"
The laughter of Liu Zhiyuan's friends was very uncomfortable.
The electric fan was whirring and the atmosphere was hot and stuffy.
Lin Chaoxi said nothing and put the books on the table into his schoolbag.
At this time, Lu Zhihao was not there. After she left the dormitory, she had a bit of a break with Yin Xiaolin and several other girls.
No one helped.
Lin Chaoxi put on her schoolbag, picked up her lunch box, and walked up to the boy who said "Young Madam".
"Do you know why most girls study hard?" She lowered her head and asked the boy seriously.
The boy raised his head and said, "Because you girls are not smart enough?"
"You're wrong," she said, "because studying hard makes us mentally and financially independent. In other words, it gives us the courage to say no to a boy we don't like and his money."
After Lin Chaoxi finished speaking, he left the cafeteria without looking back.
The summer sun is scorching.
She cursed Liu Zhiyuan and his gang of idiots in her heart, tears welling up in her eyes. She left in such a hurry that she forgot to take the remaining half of the steamed bun with her.
So sad.
——
Many mathematical theories are actually based on very simple ideas.
But it is not easy to truly understand these concepts. At the same time, converting algorithms into programs to get results requires more understanding and patient learning.
Compared with Bao Xiaomeng's learning speed, Lin Chaoxi felt that his progress was not very fast.
But this is also the result of Xiao Bao's hard work.
Lin Chaoxi actually didn't pass, but Bao Xiaomeng would really complete the study plan step by step as she said.
Study one basic module every day, complete all the exercises, and summarize the wrong questions.
One week before the final assessment of the training camp, Bao Xiaomeng had the chance to start doing the mock exam papers for the high school entrance examination and had also memorized half of the New Concept English textbook.
Without any teacher, relying on a tape and countless repetitions of listening and reading, her English has improved from being halting at the beginning to being fluent now.
Lin Chaoxi felt a sense of relief that his daughter had grown up.
It's another night with water and power outages.
She and Bao Xiaomeng moved their mats to the floor to sleep. Although she hadn't taken a shower and was sticky all over, Lin Chaoxi was still very happy and ready to go to sleep.
She turned over, and in the darkness, Bao Xiaomeng suddenly spoke.
"I'm going to look for a job tomorrow."
Lin Zhaoxi woke up instantly.
"What?"
"I saw you secretly counting money last night."
"Your use of the word 'secretly' seems a bit obscene."
"Your training camp is about to end, but you said you'd stay here with me for another half a month. We'll have to pay for food and daily expenses."
"You have such a tight study schedule every day, how can you still have time to work?"
"To support you."
The next day, Bao Xiaomeng started looking for a job.
Lin Chaoxi was still very opposed to this matter, but tomorrow was the last exam and she couldn't find time to brainwash Bao Xiaomeng.
That evening, Bao Xiaomeng waited for her at the school gate for the first time, and then took her to the door of a milk tea shop.
In Lin Chaoxi's memory, this store later opened all over the country.
"I found a job. From 6pm to 9pm every day, three hours, 10 yuan per hour." This was the first sentence the girl said.
"This is the time you spend doing mock exams every day!" Lin Chaoxi said.
"Just squeeze it in, work a little faster and sleep a little less every day, and that'll be it."
"It's not breasts. No, I don't agree. I'm going to call my dad."
"Lin Chaoxi." Bao Xiaomeng suddenly called her name.
"If you were me, let's switch places. Would you choose to work or accept my financial support?" Bao Xiaomeng asked her.
Lin Chaoxi didn't say anything.
She thought, if it were her, she would want to rely on herself no matter how difficult it was.
"Don't forget what my goal is."
Bao Xiaomeng pushed open the door of the milk tea shop and walked in.
