When Chen Wei came back, it was already more than eight o'clock in the evening, and the two old men were sitting on the sofa chatting with Nanming, and when they saw Chen Wei coming in, they both stood up and said, "Xiaowei is here, come on, start eating!"

"I'm going to be hungry, why are you late, brother?" Nan Ming complained.

Waiting for Chen Wei here, it was not just the two old men, the second and third generations of the two families had a lot, Chen Wei saw that they were all waiting for him, he was very embarrassed, and said: "Alas, studying a case, I almost forgot the time." ”

"Yes, it's getting into the groove so quickly. Old Man Qing patted him on the shoulder, pointed to a man in a police uniform next to him and said, "Come, get to know him, this is your eldest brother." ”

In fact, when Chen Wei saw him, he had already recognized who it was, and it was inevitable that he was a little cramped at this time.

Nan Ming didn't see it at all, and made a note next to him: "It's Lin Qiu's father, Brother Zhongsong." ”

The four sons of the old man Qing, named Songbai Yangtang, are all named after wood.

"Yes, I'm Lin Qiu's father. The man in the police uniform nodded and smiled, leaned sideways and said, "Come, sit, sit! It's okay to go to the new unit, are your colleagues still friendly?"

At this time, Chen Wei could have filed a complaint, but Chen Wei just smiled and said, "My colleagues are very enthusiastic. ”

"That's good, alas, I hastily transferred you here, your uncle has been complaining that I didn't ask for your opinion, and didn't cause you trouble. ”

"Where, no. Chen Wei hurriedly shook his head.

"Actually, my brother is very happy, he likes to challenge particularly difficult cases the most. "Nan Ming Dao.

And they all laughed.

Old Man Qing asked, "What case are you busy with today?"

"It's 9/27. "Now the people on the table are not ordinary people, and there is no need to keep it secret, Chen Wei told the truth.

"The 9/27 case, who gave you this case?" Qingzhongsong glared, this case is very famous within the system, it is a case of extermination. After the door was destroyed, the murderer carefully cleaned up all possible clues, and the technicians recovered a deleted WeChat voice from the deceased's mobile phone, which became the only useful clue, and the local public security bureau was unable to detect it and reported it to the criminal investigation bureau. And the Criminal Investigation Bureau has not made a breakthrough, so it has been put on hold, and it has been almost half a year now.

Isn't it embarrassing to hand over this case with only one WeChat recording as a clue to a colleague who just arrived, isn't it wearing small shoes?

"What does this little Wang want to do?" Qingzhongsong was furious.

"No, it's actually quite interesting, and today I discussed a lot of wild ideas with my colleagues, and maybe I can really find something. Chen Wei shook his head.

He naturally loves a challenge. So although he knew that this was putting small shoes on him, he still accepted the case and did not give up lightly.

Of course, if he can't solve the case, there will be gossip, saying that Detective Chen, who was specially transferred by the leader, messed up the first case when he came to the department, which would be very detrimental to his future development.

Chen Wei asked Nan Ming, "Xiao Ming." I've seen some movies before, in the movies. Can some hackers really be able to analyze the audio of the recordings to calculate the shape of the space around the speaker and determine the environment in which they are speaking?"

Nanming frowned, took out his phone and checked it, and then raised his eyebrows. "Maybe it's really possible...... And, not just the surroundings, I can give you a model of the speaker's head. ”

He handed his phone to Chen: "I found a paper, and the research team of the author of the paper built a 3D model of the Mona Lisa's head by recreating the position of the nasal cavity, lips and facial bones. It was concluded that the Mona Lisa's voice was supposed to be an old man's voice, so the Mona Lisa was a self-portrait of Leonardo da Vinci. If their theory is correct, as long as I can gather enough correspondence between voices and facial features, I can build a model to reconstruct the speaker's physiognomy. ”

"Is this possible?" Chen Wei's eyes widened, "but how much data do you need to collect to build a model?"

"It's very simple to collect data, news interviews, online selfies, online live broadcasts, reality shows, movies and TV series, you can make all the data corresponding to your face and voice, countless, you don't need to collect it separately, I'll make a phone call......" Nanming took out his mobile phone, contacted Xiaobai, and then made a few more calls to arrange a few sentences, explaining:" I know a mathematical genius named Li Xiang, he is particularly good at the design of new algorithms, Tie Dan has a deep study of facial recognition systems and 3D scanning, and then find a few people with distinctive looks from the lazy god security, establish the initial model, and the rest can be handed over to Xiaobai and Qingda Lazy God to continuously iterate and optimize, the more information collected, the more accurate the model will be, and the preliminary model will soon come out. ”

"Really?" Chen Wei was overjoyed.

"Well, it should be fine. "Nan Ming Dao.

The people next to him looked at the brothers dumbfounded, listened to the conversation between the two, and saw that the more they talked, the happier they became, the old man Qing was unhappy, coughed, and slapped the table: "Eat! Don't talk about work during dinner!"

The two of them hurried to eat obediently.

Before the meal was finished, Nanming's mobile phone rang, and a picture was sent.

On the picture, it is a 3D rendering model that looks weird, there is no hair, the eyes are pure black, and the skin tone is a layer of skin, just like a selfie with over-the-top PS, Nan Ming glanced at it and handed the mobile phone to Chen Wei: "Oh, this is a preliminary model, and only the corresponding information of more than 12,000 people has been collected so far, if it takes a little longer, there is more information collected, and it can be more accurate." ”

"So fast?" Chen Wei was stunned.

"Of course, you don't know how great my boys are!" Nan Ming Dao, Tie Dan wrote the terrifying existence of "lazy worms" in one night, he is too familiar with facial recognition, 3D modeling and other fields, write a framework program, and then Li Xiang designs an initial algorithm, Tie Dan then combines it, and the rest is left to Xiaobai and Qingda Lazy God to continue to iterate and improve themselves.

A lot of modular programming doesn't need to write code at all, just call it directly, and the internal system of the lazy god system is particularly convenient to work together, and these two people don't need to move the place at all, they can do the work while lying on the bed.

The rest of the self-redundancy and self-iteration are all working by machines.

"Basically, it's just a sub-program of a lazy bug. Nan Ming shrugged, "It's a relatively advanced neural network program, as long as the amount of computing is enough, anything can be evolved for you." ”

This kind of neural network program is said to completely replace programmers in the future, and humans are slowly teaching programs to write programs.

"I ......" Chen Wei grabbed his mobile phone and wanted to leave, but Old Man Qing slapped the table: "Eat!

Chen Wei finished his meal without knowing anything, said a word, put on his clothes and ran.

"This child, frizzy, alas. Old Man Qing shook his head.

"It's like someone when they're young. "Old man Lu is dismantling the stage next to him.

Chen Wei went out, and Xiao Zhang, who had sent him off before, immediately drove over, and in the car, Chen Wei called the young policeman who accompanied him in the afternoon and said, "Where are you? Come everywhere, I have a clue." ”

When he arrived at the office, Chen Wei didn't have time to wait for others, opened the internal network, and began to rummage through the police files of the case handling bureau at that time, rummaged through a few people, and then took the rendered photo in his hand and compared it.

"Got you. ”

I thought it was a repeat offender killer, but it turned out to be an internal scum!

Chen Wei made a phone call and tossed everyone around, didn't you put me in shoes? I also let you sleep well, and at Chen Wei's insistence, they rushed to the scene of the incident overnight and brought the policeman under control.

It was not yet dawn, and Chen Wei had not been in the office for twenty-four hours, and he had already broken a suspicion that was considered impossible to break.

"Boss, seriously, how did you solve the case?" This time, not only the young policeman was served, but even the strong policeman was served, and he came over with a shy face to ask, if he didn't understand, he might not be able to sleep for several days.

"Because I have the best technical advisor ever, you don't know how great the guys are!" Chen Wei replied with a smile. (To be continued.) )
