On the night of Tang Sa's call, Xiao Yuan and Jessica completed all their tasks, and the software they developed entered the joint debugging stage.

The so-called joint debugging is to connect the modules written by each into a complete software for debugging, which is a necessary step for the development of large-scale software division of labor, and the debugging is based on the basic assumption that there is no problem with each module, and the content of debugging is mainly focused on the interface communication between the modules and the overall function of the software.

Both Xiao Yuan and Jessica have very rich experience in software development, so their respective modules have been repeatedly tested before joint debugging, although each person is responsible for more than ten modules, and the software interface is also very complex, but the joint debugging process is very smooth, almost a success.

For this situation, the two of them are very happy, especially Xiao Yuan, during this period of time all kinds of things are entangled, if the joint debugging goes well, the later functional test of the software is mainly done by Jessica, and he can take a break from it to complete several other things, the most urgent thing is two, one is to prepare materials for the competition with Long Taijie, and the other is that Rubin gets rid of the strange data he analyzed.

In addition to the above two things, he will also have one thing to do, that is, to wait for Tang Sa to come to him and talk about image recognition, Tang Sa did not let him wait for a long time, and came to Berkeley at nine o'clock in the morning on the second day after he called, Xiao Yuan asked for leave, came out of school, and met Tang Sa at home.

"I want to make a software that can search for images on the Internet, and recognize people's faces from the images, and find the person based on facial features, and I can do the network part of the software myself, but the face recognition part of the image, can you make it?" Tang Sa took out the sketch of Carl drawn according to Gao Huaiying's description, put it on the table, and asked.

"Yes, face recognition is not a particularly difficult technology, the difficulty of this software is not here, but the acquisition of image data sources." Xiao Yuan glanced at the picture and found that it was a strange white face, so he didn't pay too much attention to it, but put forward his own opinion on Tang Sa's explanation just now.

"You don't have to worry about the data source, you just need to help me make the image recognition module." Tang Sa said.

"No problem, you wait for me for two days, I work overtime, I should be able to make it, and you scan this sketch into an image, and then find me some other images containing faces as algorithm training materials." Xiao Yuan said that the image recognition algorithm he wants to make is designed based on statistical principles, and to improve the recognition rate of the algorithm, it is necessary to use this algorithm to conduct statistical analysis of a large number of similar data in advance, this process is called algorithm training, and the materials prepared for algorithm training are called training materials.

"Okay, my sister will help you prepare these materials, how many copies of training materials do you want?" Tang Sa asked, as a computer doctor majoring in artificial intelligence, the training of artificial intelligence algorithms is also very common, so she can naturally understand what Xiao Yuan said about algorithm training and training materials.

"At least 1,000 copies, of course, the more the better, without statistics, the algorithm can't be trained, and the recognition rate can't be raised." Xiao Yuan said.

"Okay, let's divide the labor, you are responsible for writing the algorithm, and my sister will help you collect training materials, and prepare so many pictures at once, which is enough for my sister to be busy for a while." Tang Sa put away Carl's sketch, stood up as he spoke, and prepared to leave.

"By the way, you can ask Xinyu to help you prepare the training materials, Xuan Nie has a picture search, and a large number of picture materials have been accumulated in the database, you ask him to organize someone to help you screen out some of them, it should be very soon." Xiao Yuan reminded Tang Sa.

"Sister knows, you can get busy, sister will leave first, when you make the algorithm, call your sister, and your sister will come again." Tang Sa said with a smile, and was about to leave after speaking.

"Sister, are you in such a hurry to leave?" Xiao Yuan was indeed a little reluctant to Tang Sa, because there were only the two of them in the family at this time, which made his heart suddenly have an urge to move.

"If you keep your sister, my sister is willing to listen to you." Tang Sa stopped and said with a wink at Xiao Yuan.

"Let's eat at noon before leaving." Xiao Yuan stepped forward and said, for some reason, he felt that he was a little nervous, his heart was pounding violently, and his voice was trembling slightly.

"What do you want to do, it's broad daylight." Tang Sa took a step forward, straightened his already towering chest, his voice became extremely charming, and he also stretched out his tongue to Tian Tian's own ruddy lips as he spoke, and the direct effect of this series of seductive actions was that Xiao Yuan suddenly reached out and hugged her, and strode to the bedroom.

"Little villain, I want to announce yin in the daytime, wait until someone comes to the house, what do I think you should do?" Tang Sa didn't resist, and said with a smile in Xiao Yuan's ear.

"No matter, let's do it quickly." Xiao Yuan said.

"No quick fixes." Tang Sa raised his hand and slapped Xiao Yuan's shoulder and said in his ear.

"Then we'll fight for the long haul." Xiao Yuan's heart fluttered again, and he pushed open the door and walked in, locking the door with his backhand, the heat in the room was not enough for outsiders, but the living room was quiet again.

…………

"Lalala......" The little girl Qin Xiaotong held a lollipop in her hand and walked in from outside in a crisp and pleasant singing.

"Hey, why is there no one?" Qin Xiaotong looked around and found that there was no one at home, but the door was open, he felt very strange, looked around, and soon found boxes on the table in front of the sofa in the living room.

Qin Xiaotong sat on the sofa, looked around like a thief, and made sure that there was no one in the living room, so he opened the box and found that there were two fruits inside, these two fruits were round and green, very good-looking.

"What kind of fruit is this, so beautiful?" Qin Xiaotong picked up a fruit, looked at it carefully, and found that she had never seen this kind of fruit before, she put the fruit on the side of her nose and sniffed it, and a fragrance entered her nose, which made her sigh involuntarily: "Wow, it's so fragrant, I don't know what it tastes like?" ”

The little girl decided to taste it, because she didn't know what it was, and she didn't know what it tasted like, but at first she only took a small bite, but found that the fruit was rich in juice and sweet in the mouth, and she couldn't help but have a big appetite and ate it in a big gulp.

"It smells so good."

When the little girl was eating with relish, Liu Wenwen walked in from outside.

"Sister Wenwen, come and eat the fruit, the delicious fruit." The little girl was very excited, probably thinking that such a delicious thing must be shared with others, so she picked up another fruit and threw it to Liu Wenwen, and said excitedly.

Liu Wenwen looked at the fruit in her hand and found that she had never seen this fruit before, so she asked, "What kind of fruit is this?" ”

"My grandmother brought it from San Francisco, it's delicious, eat it." The little girl wanted Liu Wenwen to eat the fruit with her, so she said nonsense.

Liu Wenwen didn't doubt him, so she also took a bite of it first, and found that the fruit was really delicious, so she also ate it in a big gulp, and soon ate the fruit with the little girl.
