Liu Suian packed up the laptop and clothes in the suitcase, said hello to Fang Qian, and left the dormitory to settle lunch.

The Sipailou Campus of Southeast University is very close to Xinjiekou, the commercial center of Nanjing, which was built in the Republic of China, with a very small area, and the old dormitories are outside the campus, and there is only one road in the middle.

The cafeteria is in the dormitory area, but Liu Suian has never liked to eat in the school cafeteria, and now that it is closer, there is nothing to eat.

He found a barbecued pork restaurant nearby and ordered an authentic Cantonese barbecued pork rice.

Of course, he is not sure if it is authentic or not, he has never been to Guangdong, which was recommended by Ji Qing, a classmate who listened to the laboratory before.

After dinner, Liu Suian went to the laboratory.

As soon as he pushed open the door of the laboratory and entered, he heard the exaggerated greeting of Ji Qing, a big man from Shandong.

"You're finally done with your retreat?"

Ji Qing saw Liu Sui'an coming in, and couldn't wait to greet him and pull the latter to his seat.

"Come on, come on, help me see if there is anything wrong with my mid-term defense PPT."

As he spoke, Ji Qing pressed Liu Suian to the chair and pointed the computer screen at him.

Liu Suian took the time to glance at the laboratory, only two or three graduate students, including Ji Qing, were there, Dr. Zhang Shasha was sleeping on the table, and Han Qiming was not there.

Han Qiming's absence from the laboratory is the norm.

Liu Suian turned his head to look at Ji Qing's computer screen.

"No, you let me see what's the use, I listen to you talk about your research every time I have a group meeting, and I've almost memorized it. The teacher in charge of the defense may not understand neural networks, so you should show the younger students who have just started to participate in the group meeting to see if they can understand it if they have no foundation. ”

Liu Suian excused himself.

He is telling the truth, it's not that he doesn't want to help Ji Qing check the PPT, but this thing should be shown to people who have no foundation, to ensure that it can be explained clearly to tutors who may not have foundation.

"I've already looked for all the younger brothers and sisters in the first graduate school, and I also took the opportunity to add a junior sister's WeChat."

"Oh? Is it pretty? ”

Liu Suian and Ji Qing are both types who don't like to take the initiative to socialize, so they are not familiar with junior students.

This year, the person in charge of communicating with the junior students is another graduate student in the laboratory.

"It's okay, real people don't look good in photos." Ji Qing patted his head, "I'm being pulled away by you, look at the PPT quickly." One of the teachers in charge of my defense was working on neural networks, and I was afraid that he would ask me tricky questions, so I had to let you, the author of CVPR, look at it. ”

How did Ji Qing know that he was writing a CVPR paper?

Before Liu Sui'an could reply, a male graduate student with black-rimmed glasses on the opposite side cleared his throat first, attracting the attention of the two, and then read:

In 2020, CVPR accepted 6,656 papers and accepted 1,470 papers, with an acceptance rate of 22%.

In 2021, 7,093 papers were accepted, and 1,661 papers were admitted, with an acceptance rate of 23%.

In 2020, 8,161 papers were accepted and 2,067 were admitted, with an acceptance rate of 25%. ”

The person who spoke seemed to be reading the data without emotion, but in fact, Liu Suian and Ji Qing both heard the mockery.

Even if you Liu Suian submit to CVPR, the acceptance rate is so low, and the official does not have to be you.

The man finished reading the data and used his middle finger to hold the black-rimmed glasses on the bridge of his nose.

He is Cao Xiaohui, who has soured Liu Suian before.

Ji Qing took a few exaggerated breaths and wondered: "Liu Suian, are you back in Datong, why did you come to the laboratory with a sour smell." ”

Ji Qing inadvertently told Liu Suian's true whereabouts in the past few days.

If Liu Suian didn't know what the other party meant, he would have misunderstood that the other party was following him, and he didn't tell anyone when he returned to college.

"The old vinegar in Shanxi is not so sour." Liu Suian chuckled and said, "The southern expedition and the northern war are right, the stereotype is not advisable, Ji Qing." ”

"Mine, mine."

Ji Qing finished 'admitting his mistake', and then turned his head to look in the direction of Cao Xiaohui.

"CVPR is equivalent to the Oscar in the field of neural networks, whether you can win the award is another matter, some people can be on the shortlist, and some people dare not look at this award, this is the difference."

Ji Qing almost read Cao Xiaohui's ID number, and the latter blushed his face and buried his head to do his own thing.

Liu Sui'an discovered for the first time that Ji Qing was so good at scaring people.

This is probably what the Internet says about the mouth, cool!

For people like Cao Xiaohui, Liu Suian will not take it to heart, and when he gradually becomes bigger and stronger by relying on Bai Zehe and Pan Zhen in the future, he will definitely not be Cao Xiaohui alone.

I can't go back one by one.

When they are under the watchful eyes of these people, the more they mess up and the more they get awesome, they don't have to say anything or do anything, they will be as uncomfortable as eating.

How do you say that, seeing that kid mixes well, it's even worse than my own mix.

As for the meaning of Cao Xiaohui's words, the CVPR acceptance rate is low, and Liu Suian's paper may not be successful, so Liu Suian is not worried at all.

He has now realized a truth, just believe in Bai Ze, and wait for the rest to be the result.

Believe first, then believe, never need to question!

After the small turmoil, Liu Suian checked Ji Qing's PPT page by page.

Ji Qing's graduation project is 3D pose estimation, which specifically refers to shooting a video through one or more cameras, and then estimating the posture of the human body in the video through the video.

This is a classic project of Zhang Boheng's lab, and every year several people choose to do this.

Liu Sui calmed down and looked at Xiao for a long time.

In the end, it came out of the high-demand Zhang Boheng laboratory, this PPT is of good quality, the layout is comfortable, there are no bells and whistles, the format is also very rigorous, and I can't find out the details.

Come to think of it, Ji Qing has already found many people to change his PPT.

Among them, some of his skills in making PPT can also be learned when he does it himself.

There are no formatting and obvious logical problems, Liu Suian can only pick the bones in the egg, turn to the page of the innovation point, and point to the structural diagram.

"This PPT is already very good, that is, when introducing your workload here, you don't need to put the structure of the entire neural network on it, you can only put the changes you make, so that it looks much clearer, what do you think?"

"Indeed." Ji Qing nodded, "No wonder when I let my younger brothers and sisters watch PPT, they always stay on this page for a long time and watch it for a long time." Tsk, worthy of being a prospective CVPR author. ”

"Don't stress it all the time, hehehe."

Liu Suian smiled modestly and continued to watch.

He flipped to the page of the test results and frowned as he looked at the final test results.

"The results of your experiment are like this, and the accuracy improvement seems to be very small, and those teachers will ask when the time comes."

Ji Qing sighed and said helplessly: "Yes, Senior Sister Zhang also said this problem, but there is no way, I can only explain to the teachers when the time comes, the 3D posture estimation field is too volatile, and it would be very good to improve a little." ”

"It's not a big problem, Professor Zhang does multi-vision 3D pose estimation, and the accuracy improvement is not very good." Liu Suian said with relief.

In the field of 3D pose estimation, monocular vision refers to the use of only one camera to photograph the person to be estimated from one angle.

In contrast, multi-eye vision refers to placing cameras at different locations in the scene, taking pictures of the person to estimate the pose from multiple angles, and finally combining the images from each perspective to estimate the pose in a unified manner.

Liu Suian heard that Zhang Boheng was planning to use his research results to cooperate with a big project recently.

Speaking of Zhang Boheng, Liu Suian remembered that he planned to hand over the first draft of the CVPR paper to him.

"There is nothing wrong with other places, there are a lot of people paddling in our school, your project is definitely considered to be classy, you will definitely be able to pass, there is no need to worry."

The person who paddled in Liu Sui'an's mouth was referring to Fang Qian's kind.

During the whole graduate school, I didn't do serious work, and when I graduated, I even bought a thesis outside the school, and I didn't even know what I was doing with the paper I bought.

Of course, as Fang Qian's roommate for two years, Liu Suian did not despise him.

After all, if it weren't for Bai Ze, he wouldn't have thought about academic fraud, so he could only participate in the mid-term defense with that pitiful accuracy, and finally it would be delayed with a high probability.

After encouraging Ji Qing, Liu Suian stood up and asked, "Is Professor Zhang in the office?" ”

Ji Qing: "No. Professor Zhang's wife came to him a few days ago, and Professor Zhang didn't come for a few days after that. ”

Liu Suian: "......"

Liu Suian remembered that he had seen Zhang Boheng at Nanjing South Railway Station before, passing by arm-holding with a person who was not his wife.

Zhang Boheng won't play with fire and self-immolation, and the East Window incident happened.

Forget it, don't be in a hurry to show Zhang Boheng the first draft today, and wait for him to come back.

If Zhang Boheng doesn't come in the next few days, he can only send him the first draft through WeChat.
