Ling Zhi and the two Feng brothers are both first-year graduate students at Huacheng University.
Ling Zhi and Chen Feng met during the postgraduate entrance examination re-examination, and when they were divided into dormitories, Gao Feng and another classmate named Lin Qisong found Ling Zhi and Chen Feng and formed a dormitory.
The four of them all majored in coding. Gao Feng and Lin Qisong chose the same tutor, while Ling Zhi and Chen Feng had different tutors. Now, almost a year later, the relationship between the four of them has become very harmonious.
However, Lin Qisong did not like to play billiards. Although he had gone out with the three of them once before, his movements were very awkward and uncomfortable. After playing a few shots, he sighed and said that he wanted to quit the game.
Hence the current trio.
"To be honest, Lingzi, you are very brave today. This is the first time I've seen you strike up a conversation."
As the three of them were walking back to the dormitory, Chen Feng joked without hesitation.
"It's not that exaggerated. I usually make some golfing friends. Isn't it the same this time?"
"No, no, no, how can it be the same? Of course making friends with male golfers is different from making friends with female golfers, and you don't usually have the chance to make friends with female golfers. Please tell me honestly, are you attracted to this girl?"
"That's too much. When I play ball with others, I only talk about football, not about life or ideals. Where did you want to go?"
"Tsk, tsk, tsk! Don't underestimate common hobbies. Many beautiful feelings originate from the common hobbies of two people. Let me tell you, when I was an undergraduate..."
Chen Feng kept talking about his love experiences. He had many girlfriends when he was an undergraduate, and occasionally told Ling Zhi some of his painful experiences.
Originally, Ling Zhi was quite interested in listening to gossip, but today the target of the attack was himself, so his mood was complicated.
"...That's it, after a while, we got along well. Alas, it was just fate that got in trouble later."
"Okay, okay, don't be poor. But having said that, it's really rare for a girl to come to the ball room to practice ball. It's also the first time for me to see it. When Chen Feng was playing, I was idle and looked at it a few times.
, Her batting posture is indeed quite standard, isn’t it, Lingzi?”
Gao Feng rescued Lexus at the right time.
"Yes, it's rare to see a girl like her. It felt like she played very seriously, and I accidentally lost to her, haha!"
"Here, it's amazing. I really didn't expect this. Then you should cherish it, such an excellent golfer."
"of course."
"By the way, didn't you just join her WeChat account? What's her girl's name?"
"She said her name was Zhao Shiyan. Xishi's Shi, Yan's speech."
"Oh, the name is quite good. Oh, I'm getting old, I'm getting old. Even Lingzi has learned how to flirt with girls. But Shi Yan, break your promise. Lingzi, be careful. Maybe they will break their promise and not play with you later.
Son."
"Don't be poor, and don't ruin Lingzi's luck with your crow's mouth. Go back quickly, I still have a ppt to do, and I have to report it tomorrow."
"Oh, I'm about the same. I still have a paper to read and a report to make in a few days..."
Listening to the conversation between the two Feng brothers, Ling Zhi couldn't help but have his thoughts spread.
He wasn't worried about breaking his promise or anything, the girl didn't seem like that, he was thinking about other things.
Zhao Shiyan came to play ball alone so late, so he probably lived nearby. Was he also a student of Huacheng University? Or was he from other schools in the surrounding area? While his mind was spinning, he took out his mobile phone and clicked on Zhao Shiyan's WeChat account.
"You played really well. I had a lot of fun playing tonight. Thank you [smiling]."
Lexus sent it.
After a while, Zhao Shiyan responded to the message.
"Me too, that's why I want to thank you, haha."
It was a normal reply. Lexus hesitated for a moment and continued to send the message.
"I am a first-year graduate student at Huacheng University, majoring in computer science, but after this summer vacation I will be a second-year graduate student [dumbfounded]. What about you? Are you also a student from a nearby school?"
"Wow! Computer master, you are awesome. Then I should call you senior. I am a prospective graduate student at Linhai University next door. I just passed the exam this year. I applied for the sociology major. I came here early during the summer to familiarize myself with the environment [laughing].
"
"Okay, okay, you are also a talented woman. But I am not a great master, I am just an ordinary graduate student. I cannot withstand your praise."
"Don't be modest. Computer science is very advanced for people in our major, let alone those who are admitted to graduate school. When I was an undergraduate, I studied medical information management. This major is very fascinating. I am in the School of Management, but usually
The course I took involved some computer knowledge, which really confused me at that time, so I know that computer students are very powerful."
"Actually, it's not as great as you think. We are all newbies, and we still have a lot of knowledge that we don't understand and need to learn more. But it's a bit strange. Your undergraduate major was information management. How come you got a master's degree in sociology?
Is it interprofessional?”
"Oh, I forgot to tell you, I originally applied for a major in economics and management, but unfortunately I didn't pass the exam, so I transferred to a nearby sociology department. Sociology is also related to management, so it feels like a small leap.
, after all, information management is more engineering, and sociology is more liberal arts."
"I see, your journey to take the postgraduate entrance examination is not easy, but it's good if you can pass it. Your hard work over the past year will be worth it."
"Yeah, thank you for saying that."
Lingzhi didn't know what to say in the next minute and was about to say good night to her.
"Oh, by the way, I told you, remember to wash your hands, don't forget it."
Ling Zhi was stunned for a moment, then shook his head, and replied to her dumbfounded:
"Okay, I got it [dumbfounded]."
"I'm serious, don't take it seriously."
"As ordered, Miss Zhao [hand over]."
"Okay, I won't disturb you anymore. Don't fight too late. Go back and rest early."
"Obviously it's me who disturbs you [dumbfounded], but you do the same, go to bed early."
After waiting for a while, seeing that Zhao Shiyan stopped replying, Ling Zhi took back his phone and followed his roommate back to the dormitory.
The first thing he did when he returned to the dormitory was that Ling Zhi got into the bathroom and washed his hands. Although he didn't think it was a big deal, it was his usual style to do what he promised others.
"Hey, why did you come back so late and are you so enthusiastic about your billiards career?"
Lin Qisong, who stayed in the dormitory, asked.
"It was really fun to play billiards. Lingzi made a god-level move, which stunned me and Gao Feng. But this was not the main reason."
Seeing that Lin Qisong's attention was drawn to him, Chen Feng embellished the story about how Ling Zhi went to play with Zhao Shiyan.
"Anyway, in order not to disturb them, Gao Feng and I deliberately fought for a while longer, and that's why it's been delayed until now."
"Okay, Ling Zhi, I didn't expect you to have such conversation skills. Hey, is it too late to learn billiards from you? I want to strike up a conversation too."
"Stop teasing Lingzi. If you go too far, Lingzi won't play with us anymore."
"Oh, yes, but I believe Lingzi is not the kind of person who values sex over friends. He will still play ball with us, right Lingzi?"
Ling Zhi just came out of the bathroom and looked at his left hand, thoughtfully.
"It's over, it's over, it's a prophecy. Lingzi doesn't care about me anymore."
Chen Feng covered his head and looked up to the sky and sighed.
"Ah, what?"
He was thinking about other things just now. Although he was listening to the conversation of his friends at the same time, he didn't pay much attention to it. At this time, he thought about it carefully and said helplessly:
"I'm following you wherever I go. I just added them on WeChat. I don't know whether I will have time to make an appointment in the future. I will definitely play ball with you again."
"That's good, that's good."
Chen Feng saw that Ling Zi was absent-minded and had no intention of teasing him. After that, the roommates went about their own business, while Ling Zhi sat in his seat in a daze.
"It must be an illusion."
He sighed softly, didn't think much about it, and went to bed early after washing up.
Early the next morning, Ling Zhi and Chen Feng, who got up at the same time, went to the cafeteria to eat together.
"You've always been the third child. You always have a small bowl of fried noodles, an egg and a bowl of porridge every morning. I haven't seen you change. I really can't do it. I really don't have the appetite to eat such oily fried noodles in the morning."
"It's okay, Lingzi. You can try it another day. It's actually not as greasy as you thought. Besides, aren't you the same as the third child? A cup of soy milk, an egg tart and a piece of bread."
Ling Zhi's appetite is average in the morning and he won't eat much. Although his mother repeatedly reminds him to try to eat an egg and drink a glass of milk every morning every morning. But peeling eggs is too troublesome, so he uses egg tarts and milk instead.
It was difficult to digest, so I just drank soy milk. Alas, it was all white anyway, so that was almost enough.
"Okay, I'll try your fried noodles another day when I'm really hungry in the morning."
Ling Zhi said nonchalantly. When it comes to eating, Ling Zhi has always kept things simple, just filling his stomach and not having too many requirements.
After dinner, the two of them came to the college building together.
"Well, the experiment I did recently didn't go well. I couldn't adjust it well no matter how I adjusted it. I'm worried to death."
Chen Feng complained casually on the road.
"What bug? Does the program keep reporting errors? Isn't your code provided by the original author of the paper? Why is there still a bug?"
Although both majored in computer science, their research directions are quite different.
Chen Feng studies medical image processing. He said that his specific task is to select pictures with diseased areas from thousands of eyeball pictures.
Logically speaking, it is a simple two-classification, that is, using a deep neural network to train a model, and using the model to divide the pictures into those with lesions and those without lesions, but Lexus knows that things may not be that simple.
"It's not that it's an error. The program can be adjusted. It's just that I can't get the effect described in the original paper. I'm so worried."
"It doesn't matter if you can't run. Your data set was created by your division. It's different from the data set used in the original paper. Just try to adjust it as much as possible. Isn't it normal that it can't run?"
In the computer industry, data sets are definitely the foundation of the foundation. Whether the experimental results are good or not and whether the data set quality is high are the key.
A high-quality preprocessed data set is likely to make your experimental results twice the result with half the effort, so many computer science graduate students try to choose data sets published by the original author when doing experiments, so that they only need to focus on writing their own programs.
Already.
Many graduate students have taken advantage of this convenience to publish multiple papers in one go, thus saving up for graduation early.
However, there are still some graduate students who have embarked on a thorny road. There are no public data sets in their research fields, and some research fields are even emerging fields. There is no definite way to study them, let alone a data set.
In this case, graduate students need to collect their own data sets and pre-process them. The workload is unimaginable.
Unfortunately, the research directions of Ling Zhi and Chen Feng both fall into the latter category.
