Ling Zhi and two brothers Feng are both first-year graduate students at Huacheng University.

Ling Zhi and Chen Feng met during the postgraduate entrance examination. When they were divided into dormitories, Gao Feng and another classmate named Lin Qisong found Ling Zhi and Chen Feng and formed a dormitory.

All four of them studied coder majors. Gao Feng and Lin Qisong chose the same mentor, and Ling Zhi and Chen Feng's mentors are different. Now almost a year has passed, and the relationship between the four people is already very harmonious.

However, Lynchson doesn't like playing billiards. Although he had come out with the three of them once before, he felt very awkward and uncomfortable in his movements of the pole. After a few shots, he sighed and said that he was going to withdraw from the ball. So the current trio was found.

"To be honest, Ling Zi, you are very brave today. The first time you meet you."

The three of them were walking back to the dormitory, and Chen Feng joked unswervingly.

"It's not that exaggerating. Don't I often make some golfers? Isn't it the same this time?"

"No, no, no, how can it be the same? Of course, it is different from having a boyfriend and a girlfriend, and you don't have the chance to have a girlfriend. You should be honest and honest, are you interested in other girls?"

"It's too much. I just talk about football with others, not about life and ideals. Where do you want to go?"

"Tsk tsk tsk! Don't underestimate common hobbies. Many beautiful feelings come from the common hobbies of two people. Let me tell you, when I was a bachelor's degree..."

Chen Feng kept talking about his love experiences. He had had many girlfriends when he was a bachelor's degree, and occasionally told Ling Zhi about his painful experiences.

Originally, Ling Zhi was quite interested in listening to gossip news, but today he was targeting himself, so his mood became complicated.

"...It's like that, after a while, we both got along. Alas, it's just that luck made people happen later."

"Okay, okay, don't be poor. But then again, it's really rare for a girl to come to the ball room to practice. It's the first time I saw her. When Chen Feng was playing, I looked around and looked at her a few times. Her batting posture was indeed quite standard, right, Ling Zi?"

Gao Feng helped Lingzhi to help him solve the situation in time.

"Yes, I rarely see a girl like her. I feel like she beats very seriously, and I accidentally lost to her, haha!"

"I'm going, it's amazing. I really didn't expect it. Then you have to cherish it, such an excellent golfer."

"Of course."

"By the way, didn't you just add someone else's WeChat? What's the name of the girl?"

"She said that her name is Zhao Shiyan, Xi Shi's Shi, the words of the words."

"Oh, the name is pretty good. Oh, I'm old, I'm old. Even Lingzi has learned to flirt with girls. But Shi Yan, break your promise. Lingzi, be careful, maybe people will break their promises and stop playing with you."

"Stop being poor, don't say that your love luck is gone with a crow mouth. Go back quickly, I still have a ppt but haven't done it, and I will report it tomorrow."

"Oh, I'm about the same, I still have a paper to read, and I'll report it in a few days..."

Listening to the conversation between the two brothers Feng, Ling Zhi couldn't help but spread his mind.

He was not worried about breaking his promise or something. The girl didn't seem to be such a person, and he was thinking about other things.

Zhao Shiyan came to play basketball alone so late, so he should live nearby. Could it be that he is also a student of Huacheng University? Or is it from other schools around? While he was thinking, he took out his cell phone and clicked on Zhao Shiyan's WeChat.

"You played really well. I played very happily tonight. Thank you for [smiling]."

Lexus sent it over.

After a while, Zhao Shiyan replied to the news.

"So, I want to thank you, haha."

A very normal reply, Ling Zhi hesitated for a while and continued to send messages.

"I am a first-year graduate student at Huacheng University. I am majoring in computer science, but after this summer I will be a second-year graduate student [hilarious and crying]. What about you? Are you also a student from a nearby school?"

"Wow! The computer master is amazing. Then I should call you senior. I am a prospective graduate student from Linhai University next to me. I just passed the exam this year and applied for the major of sociology. I came here in advance for the summer vacation to get familiar with the environment [grin]."

"Yes, you are also a talented woman. But I am not a great god, I am just an ordinary graduate student, and I can't stand your praise."

"Don't be humble. Computers are very high-end for people of our majors, let alone those who have passed the postgraduate entrance exam. When I was a bachelor's degree, I studied medical information management, and this major was very fascinated. It was included in the School of Management. However, the courses I took usually involve some knowledge about computers. At that time, I really missed me, so I knew that computer students were very good."

"Actually, it's not as good as you think. We all came from a novice, and there are still a lot of knowledge that we don't understand to learn further. But it's a bit strange. Your undergraduate degree is information management, so how did you get into sociology after a graduate student? Is it a cross-profession?"

"Oh, I forgot to tell you that I originally applied for the major in economics and management, but unfortunately I didn't get the exam and transferred to the nearby sociology. Sociology is also a bit related to management, so I feel a little bit like a small span. After all, information management is biased towards engineering, and sociology is biased towards liberal arts."

"So that's it. Your postgraduate entrance examination process is not easy, but it's good to be able to pass the exam, it's not worth your efforts over the past year."

"Yeah, thank you for saying that."

The next minute, Ling Zhi didn't know what to reply and was about to say good night to her.

"Oh, by the way, I told you, remember to wash your hands, don't forget."

Ling Zhi was stunned for a moment, then shook his head and replied to her with amusement and tears:

"Okay, I know [hilarious and crying]."

"I'm serious, don't take it seriously."

"As for orders, Miss Zhao [receives]."

"Okay, I won't bother you anymore. Don't fight too late, go back early to rest."

"It's obviously me who disturbs you [hilarious and crying], but so are you, so do you, take a break soon."

After waiting for a while, seeing that Zhao Shiyan stopped replying, Ling Zhi took back his cell phone and followed his roommate back to the dormitory.

The first thing he did when he returned to the dormitory was that Ling Zhi first went into the bathroom to wash his hands. Although he didn't think it was a big deal, he had to do what he promised others, which was his usual style.

"Oh, why are you back so late? Are you so passionate about your billiards career?"

Lynchson, who stayed in the dormitory, asked.

"The billiards are really exciting. Ling Zi hit a divine move, which made Gao Feng and I stunned. But this is not the main reason."

Seeing that Lin Qisong was attracted by his attention, Chen Feng added jealousy to the process of Ling Zhi asking Zhao Shiyan to play basketball.

"Anyway, in order not to disturb them, Gao Feng and I deliberately fought for a while, and it was only now."

"Yes, Ling Zhi, I didn't expect you to have this kind of chat skills. Hello, is it still too late to learn billiards from you? I'm going to chat with you too."

"Don't tease Ling Zi. If it's too much, Ling Zi won't play with us in the future."

"Oh, that's true, but I believe Ling Zi is not the kind of person who values ​​sex over friends. He will still play basketball with us, right? Ling Zi?"

Ling Zhigang came out of the bathroom and looked at his left hand, thinking.

"It's over, it's done, it's a prophecy. Ling Zi ignores me."

Chen Feng covered his head and sighed at the sky.

"Ah, what?"

He was thinking about something else just now. Although he was listening to the conversation between his friends at the same time, he didn't care much. He thought about it carefully and said helplessly:

"I just added someone else's WeChat. It's not sure if I have time to make an appointment in the future. I will definitely play basketball with you."

"That's good, that's good."

Seeing that Ling Zi was absent-minded, Chen Feng lost the intention of making fun of him. After that, the roommates were busy with their own affairs, and Ling Zhi sat in his own position in a daze.

"It should be an illusion."

He sighed lightly, and without thinking too much, he took a break earlier after washing up.

The next morning, Ling Zhi and Chen Feng, who got up at the same time, came to the cafeteria for dinner.

"You have always been the third child. Every morning, you have never seen a small bowl of fried noodles, an egg and a bowl of porridge. 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, but it's not as good as you think. Besides, you're the third one too? A cup of soy milk, an egg tart and a bread."

Ling Zhi has a normal appetite in the morning and does not eat too much. Although his mother calls him and reminds him to try to eat an egg and drink a glass of milk every morning. But it is too troublesome to peel the eggs, so he uses egg tarts instead. The milk is not easy to digest, so he simply drinks soy milk. Alas, it is all white anyway, so it's almost done.

"Okay, I'll try your fried noodles when I'm so hungry the next morning."

Ling Zhi said without much care. When it comes to eating, Ling Zhi has always been simple and can fill his stomach. He doesn’t have much requirements.

After dinner, the two of them came to the college building together.

"Oh, the experiment I've done recently is a bit unsuccessful. No matter how you adjust it, I'm so worried."

Chen Feng complained casually on the road.

"What bug? Is the program constantly reporting errors? Is your code not provided by the original author of the paper? Why are there any bugs?"

Although both of them studied computer science, their research directions are still very different.

Chen Feng studied medical image processing. He said that it was a topic of selecting pictures of the lesions in thousands of pictures of eyeballs.

It is a simple binary classification, that is, using deep neural networks to train a model, and use the model to divide the pictures into lesions and non-lesions, but Lingzhi knows that things may not be that simple.

"It's not that it's an error. The program can be adjusted, but it just won't be able to escape the effect described in the original paper. I'm so worried."

"It doesn't matter if you can't run. Your dataset is made by your master. It's different from the datasets used in the original paper. Just try to adjust it as much as possible. Isn't it normal to run it?"

In the computer industry, data sets are definitely the foundation of the foundation. Whether the experimental results are good and whether the data set quality is high is the key.

A high-quality preprocessed dataset may make your experiment more effective, so many computer graduate students try to choose the dataset published by the original author when doing experiments, so that they only need to focus on writing their own programs.

Many graduate students have published many papers in one go with this convenience and have accumulated enough graduation requirements early.

However, some graduate students have embarked on a thorny path. There is no public data set in their research field, and some research fields are even an emerging field. There is no definite path for how to study it, let alone data sets.

In this case, graduate students need to collect their own data sets and preprocess them. The workload is unimaginable to ordinary people.

Unfortunately, both Ling Zhi and Chen Feng's research directions belong to the latter.
