Hope always makes people motivated, even if they are physically tired, they are happy.

During the day, Moyan has to go to class, so Aunt Xu takes care of her grandmother in the hospital, and Moyan goes to the hospital to change shifts at night.

Back at school, after Moyan finished class, he hurried to the computer club laboratory, and learned that she was going to use the laboratory, and Qin Xiao waited there very intimately in advance.

When he saw the ink smoke around the corner from afar, he greeted loudly, "Hi, little smoke." ”

In her eyes, Qin Xiao was very good except for being a little enthusiastic.

Mo Yan waved his hand at him, Qin Yan didn't appear, she felt very good intellectually, the two of them returned to dust and dust, drawing a clear line, but the imperceptible loss in her heart was only known to her.

A few minutes later, Moyan walked to the door of the laboratory and greeted him with a smile.

"Sister-in-law... Xiao Yan'er, is it okay for you to do the test alone? I'll help you. Qin Xiao touched the tip of his nose, and then asked kindly.

He was given a death order by Brother Yan, and he wanted to take care of his sister-in-law, the O he had taken a fancy to recently

kyoH900M headphones, there is a fall.

Mo Yan paused, she was not familiar with the test equipment, if someone helped, of course, it would be good, and Qin Xiao's computer level was also good, maybe he could give her valuable advice.

"Okay, that's for you."

After speaking, Mo Yan followed Qin Xiao in.

Qin Xiao first opened the test equipment properly and debugged it, "It's okay, you can match the program code and try it." ”

The ink smoke should be down, the tender white slender fingers jumped on the keyboard, and the test soon began; They used a lot of portrait images for the initial experiment, and the results were good, and the accuracy reached the expected goal.

"But we don't use actual faces to do the test, and the data will be biased, especially in terms of computing speed." Mo Yan looked at the results on the screen and frowned.

Qin Xiao raised his head and looked at her, "It's easy to say, I'll coordinate with the school to install the camera at the school gate, identify the faces of the students, and compare the file size photo data, so that it is closer to reality." It's all over me. ”

After speaking, he patted his chest.

Seeing this, Mo Yan smiled and nodded, "Okay, then I'll trouble you, how many days will it take?" ”

"It's okay tomorrow, you don't have to look at who I am, Z big and small overlord, hehehe..."

"Well, thank you very much, then I'll come back to you tomorrow."

When the words fell, Mo Yan hurriedly left.

QIN YAN PUT HIS HANDS IN HIS POCKETS, WALKED OUT OF THE CLASSROOM WHERE HE WAS HELPING, AND GLANCED AT THE HOUR LIGHTLY, "BLACKLOTUS HAS ASKED US TO PLAY IN THE X LEAGUE, YOU CAN DOCK AND CONFIRM THAT THE TEAM MEMBERS ARE ARRANGED." Also, collect their personal information as much as possible, especially their leader, Dimo

。 ”

"Roger, Captain Integrity." Qin Xiao raised his right hand and saluted in response.

When she returned to the hospital, she carefully wiped her grandmother's body and changed into clean clothes before coaxing her to lie down.

Grandma is like a child now, and someone has to play with her all the time and tell her stories.

Mo Yan told her the story of "The Legend of the White Snake" today, which was also told to her by her grandmother when she was a child.

A cold and pleasant voice slowly sounded in the ward, "Grandma, Yanyan has told you a story, close your eyes and listen obediently." Many, many years ago, there was a beautiful and kind little white snake, she was a little playful, and she ran to the river alone to play, and met the terrible black eagle......"

Soon after, the sound of even breathing was heard, and the sound of her speech became smaller and smaller, and finally stopped, and my grandmother was already asleep.

The operation was scheduled for three days later, and although it was not a major operation to install a stent on the heart, my grandmother was still worried because she was old.

She touched her grandmother's face, she had climbed the traces of time, she looked like her mother, and her mother looked like her grandmother, so she also looked like her grandmother, and her grandmother was also a big beauty when she was young.

Then he held his grandmother's warm hand and sat back on the chair next to him.

I remember when I was a child, on a stormy night, she had a high fever all night, and my grandmother also accompanied her, guarded her, helped her cool down physically, and didn't sleep all night.

Such a good grandmother, her only relative, Lu Entropy, how dare you, how dare you!!

Do it all over again, and everything will be fine.

The next day, Moyan returned to the computer community laboratory to review the measured data of face recognition technology.

Mo Yan checked the information and broadcast the test data, "Starting at eight o'clock in the morning and ending at four o'clock in the afternoon, within eight hours, 10,845 faces were scanned, and now we can officially start testing the accuracy and efficiency of the recognition algorithm." ”

"Hey, hey, Xiaoyan'er, your algorithm model is very powerful, better than our computer department." Qin Xiao looked at the algorithm code she called up, and couldn't help but give a thumbs up next to him.

Mo Yan stared at the progress of the screen carefully, she had already opened up the database of student files, and now she was running the algorithm for comparison and identification, but she did not answer.

I have to say that the camera and computing equipment that Qin Yan found are very strong, and the identification was completed in a few minutes.

However, the recognition accuracy is only 94%, which is still a long way from the target.

Ink cigarette is based on two-dimensional face recognition, principal component analysis (PCA) method, and the PCA-based face recognition system faces an important obstacle in its application: the problem of incremental learning. Therefore, the accuracy of this method will become worse and worse when there are more faces. The biggest advantage of this method is that it is efficient, so it is still different from the original idea.

She explained a little to Qin Xiao and wanted to hear his advice.

Qin Xiao thought for a moment, and then said slowly, "Well, the incremental PCA algorithm is the most important PCS reconstructed by the new samples, but with the increase of samples, this method needs to constantly discard some unimportant PCs to keep the subspace dimension unchanged. So, you should be too focused on efficiency initially, and I suggest you try a different algorithm, such as from a 3D perspective. ”

After listening to the words of the hour, Mo Yan felt that it was not unreasonable, and then asked, "Three-dimensional algorithm?" Is there a professor in the Department of Computer Science at Z University who can I ask for advice? ”

"Well, the computer department of our school is better at network security and information systems, and face recognition technology belongs to the category of artificial intelligence, and Professor Li Du of Q University is very good at this, why don't you visit him?"

"Can you get in touch with him?"

"He is very familiar with my mentor, and I have consulted him a few times, and he is a good mentor who answers all questions."

Mo Yan looked at the dazzling accuracy on the screen, and hated to solve it immediately, so he had to urge Qin Xiao, "It's better to choose a day than to hit the day, you contact now, if it's convenient, go over now." ”

Qin Xiao called Professor Li Du and quickly got the other party's consent.

After hanging up the phone, he touched the back of his head slightly apologetically, "Xiao Yan'er, although I really want to accompany you, but the mentor has an urgent matter to summon me just now, you see, do you want Brother Yan to accompany you?" He drove to the school and it was convenient. ”

"It's okay, I'll take a taxi myself." Mo Yan didn't appreciate it, so he packed up his things and prepared to go out.

Qin Xiao chased out, and just happened to meet Qin Yan at the staircase, she immediately greeted warmly, "Brother Yan, aren't you going to Q Dan to get the materials?" Drop by and put the small... Bring Mo Yan over, she's going to find Professor Li Du. ”

Qin Yan glanced at them lightly, and then asked Mo Yan casually, his tone was extremely flat, "Are you leaving?" ”

"Myself..."Mo Yan looked at him, just about to refuse,

was pushed out by Qin Xiao, "Let's go, Professor Li Du said that he had a class at half past four, and now it is three forty, and it will be half an hour to drive over to Q University, and it will be too late." ”

Mo Yan couldn't, so he had to trot all the way and get into Qin Yan's car, an orange Lamborghini U

us, which does not match his lazy temperament at all.

At four o'clock, the car arrived at the gate of Q, Qin Yan went to the law school to get information, and Moyan went to the computer department to see the legendary Professor Li Du, an authority in computer artificial intelligence in China.

In the professor's office, Professor Li Du sat behind his desk, wearing silver-rimmed glasses, full of bookishness, and it was difficult to know that he was a science and engineering professor from the outside.

He was stunned when he saw Mo Yan, his face was full of surprise, and he asked tentatively, "Are you Tianyu's daughter?" ”
