Hope always makes people full of energy and makes them happy even if they are tired.
Mo Yan had to go to class during the day, so Aunt Xu took care of her grandmother in the hospital, and Mo Yan went to the hospital to change shifts at night.
Back at school, after Mo Yan finished her class, she hurried to the computer club laboratory. When she learned that she was going to use the laboratory, Qin Xiaoshi was very considerate and waited there in advance.
I saw Mo Yan at the corner from a distance, so I said hello loudly, "Hi, Xiao Yan'er."
In her eyes, Qin Xiaoxiao was pretty good except for being a little enthusiastic.
Mo Yan waved to him, but Qin Yan didn't show up. Intellectually, she felt very good. The two of them had returned to dust and had drawn a clear line, but she was the only one who knew the unobservable loss in her heart.
A few minutes later, Mo Yan 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? Let me help you." Qin Xiaoxiao touched the tip of his nose and asked kindly.
He was given a death order by Brother Yan and had to take good care of his sister-in-law, the one he had fallen in love with recently.
The kyoh900m headphones are here.
Mo Yan paused for a moment. She was not familiar with the testing equipment yet. It would be great if someone could help. Besides, Qin Xiaoshi's computer skills were also good, so he might be able to provide her with valuable suggestions.
"Okay, I'm sorry to trouble you."
After saying that, Mo Yan followed Qin Xiaoxiao and walked in.
Qin Xiaoshi first opened the test equipment properly and debugged it. "That's it. You can try matching the program code."
Mo Yan responded, his white and slender fingers jumping on the keyboard, and the test began quickly; they used many portrait pictures for preliminary tests, and the results were good, and the accuracy rate reached the expected goal.
"But we are not using actual human faces for testing. 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, "This is easy to say. I will coordinate with the school to install the camera at the school gate, recognize the faces of the students, and compare the profile photos. This will be closer to reality. This matter includes
On my body."
After saying that, he patted his chest.
Seeing this, Mo Yan smiled and nodded, "Okay, I'll bother you then. How many days will it take?"
"You can do it tomorrow, don't even look at who I am, the big bully, hehehehe..."
"Well, thank you very much. I'll come back to you tomorrow."
As soon as he finished speaking, Mo Yan left in a hurry.
Qin Yan put his hands in his pockets and walked out of the classroom where he was helping. He glanced at the hour and said, "Blacklotus has invited us to compete in the
It's their leader Dimo
."
"Roger that, Captain Lian Zhen." Qin Xiaoxiao raised his right hand and saluted in response to the situation.
When Mo Yan returned to the hospital, he wiped her grandmother's body carefully and put on clean clothes before coaxing her to lie down.
Grandma is like a child now. She needs someone to play with her and tell stories all the time.
Mo Yan told her the story of "The Legend of White Snake" today, which was also told to her by her grandmother when she was a child.
A cold and sweet voice slowly sounded in the ward, "Grandma, be good, Yanyan is telling you a story. Close your eyes and listen. Many, many years ago, there was a beautiful and kind-hearted little white snake. She was a little playful and wanted to be alone.
I ran to the river to play and met the terrifying black hawk..."
Soon after, the sound of even breathing was heard. Her speaking voice became smaller and smaller, and finally stopped. Grandma had fallen asleep.
The surgery is scheduled for three days later. Although installing a heart stent is not a major surgery, my grandma is still worried because she is old.
She touched her grandma's face and saw that the traces of time had already appeared. She looked like her mother, and her mother looked like her grandma, so she also looked like her grandma. Her grandma was also a beautiful woman when she was young.
Then she held grandma's warm hand and sat back on the chair next to her.
I remembered that when I was a child, on a stormy night, she had a high fever all night long. Her grandmother stayed with her, guarded her, and helped her physically cool down, and she didn't sleep all night.
Such a good grandmother, her only relative, Lu Entropy, how dare you, how dare you!!!
In the next life, everything will be fine.
The next day, Mo Yan returned to the Computer Society Laboratory to review the actual measurement data of face recognition technology.
Mo Yan checked the information and reported the test data, "Starting at eight in the morning and ending at four in the afternoon, 10,845 faces were scanned within eight hours. Now we can officially start testing the accuracy and efficiency of the recognition algorithm.
"
"Hehehehe, Xiao Yan'er, your algorithm model is very powerful, even better than those in our computer science department." Qin Xiaoxiao looked at the algorithm code she had called up and couldn't help but give a thumbs up.
Mo Yan stared at the progress of the screen carefully. She had opened the student profile photo database and was now running the algorithm for comparison and identification. She did not answer the call.
It has to be said that the camera and computing equipment Qin Yan found are very powerful, and the recognition was completed in a few minutes.
However, the recognition accuracy is only 94%, which is still far from the target.
Moyan uses the principal component analysis (pca) method based on two-dimensional face recognition. The PCA-based face recognition system faces an important obstacle in its application: the incremental learning problem. Therefore, this method is more suitable for people with more faces.
Under certain circumstances, the accuracy will become worse and worse. The biggest advantage of this method is its high efficiency, so there is still a deviation from the original idea.
She explained it to Qin Xiaoxiao a little and wanted to hear his advice.
Qin Xiao thought for a moment, and then said slowly, "Well, the incremental PCA algorithm reconstructs the most important PCs from new samples, but as the samples increase, this method needs to continuously discard some unimportant PCs to maintain the subspace dimension.
No change. Therefore, you may have focused too much on efficiency initially. I suggest you change the algorithm, for example, try it from a three-dimensional perspective."
After listening to what Xiao Xiao said, Mo Yan felt that it was reasonable, and then asked, "Three-dimensional algorithm? Is there a relevant professor in the Department of Computer Science at University Z that I can ask for advice?"
"Well, the computer department of our school is better at network security and information systems. Face recognition technology belongs to the category of artificial intelligence. Professor Li Du from Q University is very good in this area. How about going to visit him?"
"Can you contact him?"
"He is very familiar with my tutor. I have asked him for advice several times. He is a good tutor who answers all my questions."
Mo Yan looked at the dazzling accuracy on the screen, wishing he could solve it immediately, so he had to urge Qin Xiaoshi, "It's better to choose a different day than to hit it. You can contact me now. If it's convenient, go there 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 apologetically, "Xiao Yan'er, although I really want to accompany you, the instructor just summoned me for something urgent. Look, why don't you let Brother Yan accompany you? He will drive here.
The school is very convenient.”
"It's okay, I'll take a taxi there myself." Mo Yan didn't appreciate it, so he packed his things and prepared to go out.
Qin Xiao chased out and happened to meet Qin Yan at the stairs. She immediately greeted her warmly, "Brother Yan, aren't you going to Q University to get materials? Take Xiao... Mo Yan over there, she's going.
Find Professor Li Du."
Qin Yan glanced at them lightly, and then asked Mo Yan casually, with an extremely calm tone, "Are you leaving?"
"Myself..." Mo Yan looked at him and was about to refuse,
He was pushed out by Qin Xiaoxiao, "Let's go quickly. Professor Li Du said he has class at 4:30. It's 3:40 now. It will take half an hour to drive to qqda. It's too late."
Mo Yan had no choice but to jog along and get into Qin Yan's car, an orange Lamborghini u
us, it doesn’t match his lazy temperament at all.
At four o'clock, the car arrived at the Q gate. Qin Yan went to the law school to get materials, and Mo Yan went to the computer department to meet the legendary Professor Li Du, an authority on computer artificial intelligence in China.
In the professor's office, Professor Li Du is sitting behind his desk, wearing silver-rimmed glasses and full of bookish air. It is difficult to tell from his appearance that he is a professor of science and engineering.
He was startled when he saw Mo Yan, his face full of surprise, and he asked tentatively, "Are you Tianyu's daughter?"
