Ye Gui took a closer look, and that person was Zhang Rui. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It's just that he looks a little more immature than the Zhang Rui he knew back then.

Correspondingly, there is also a little more arrogance between the eyebrows.

Seeing Zhang Rui's thoughtful and meditative look, Ye Gui didn't bother directly, but leaned in curiously.

In later generations, Zhang Rui did development, did testing, and finally lived in an information security company.

Ye Gui really didn't know what he was doing in college.

I glanced at it twice, the familiar interface style, and the clear code structure.

Ye Gui couldn't help but smile dumbly.

"Is there anything wrong with you?"

Zhang Rui was disturbed by the laughter behind him, and turned his head to find a boy staring at his computer screen, a little confused.

"Neural networks?"

Ye Gui didn't answer his question, but glanced at the code on the computer twice and asked Zhang Rui rhetorically.

Zhang Rui smiled when he heard this, and said, "Master, even graduate students rarely know that this is neural network code after two glances. ”

Ye Gui said: "This is not an ordinary neural network, it should be an improved version, I see that there are a few traditional parameters that you don't use." ”

"That's right! This is my own modified version, because what I want to use requires a low-complexity algorithm, so I improved one myself, and the fewer parameters than the original version is an advantage, I didn't expect you to see it at a glance. ”

Zhang Rui didn't expect the boy in front of him to be able to see what he wrote at a glance, and he was suddenly a little excited: "Are you also a student of Shuimu, I haven't seen you before." ”

"I'm not from Mizuki, uh, I'll be from Kyoto University in a few months." Ye Gui said with a smile, Zhang Rui's eyes were very familiar to him, and those fanatical technicians in later generations had this expression when they saw Da Niu.

Zhang Rui was stunned for a moment, and then he was a little relieved, and said, "You came to find our teacher, he often goes to Beijing University." ”

"No, I'm coming for you."

"Me?" Zhang Rui pointed to his nose and asked in confusion.

The corners of Ye Gui's mouth pulled an arc, nodded, and said playfully: "It's almost lunch, let's go out to eat and chat?" ”

Although the two have only met once, with Ye Gui's understanding of him, there are not many people in China who have such attainments in neural networks at this time, and Zhang Rui will not give up an opportunity to communicate.

Sure enough, Zhang Rui said without hesitation: "Let's go, there is a small shop near the school, I invite you to dinner." ”

Ye Gui laughed and said, "You can choose the place, but let me invite this meal, because I am here to ask for your help." ”

"How can it help? You just have to say it, just because you can see my code at a glance, I am willing to make you a friend. Zhang Rui said coolly.

"That's not going to work, one yard to one yard, we'll talk about it later."

……

Two people, four dishes and one soup, plus a restaurant near the school, the amount is full.

So when Ye Gui and Zhang Rui's table was full, it attracted the sideways glances of some people around them.

Ye Gui didn't care so much, picked up the beer and poured two glasses.

"Zhang Rui, I know you have a lot of questions, but I'll explain them to you later, let's go first."

met a friend I hadn't seen for a long time, and Ye Gui's state today was a little hilarious.

Neither of them is a good drinker, but the first drink is refreshing.

"Ahh

Not because of the beer, but because the feeling is all too familiar.

Kyyodai and Mizuki Gate face each other, so students from the two schools will have something in common.

For example, this small restaurant at this time.

Ye Gui clearly remembers that he would come here with his classmates to have a meal every weekend to improve the food.

He remembers all the specials at this place.

Because those cheap side dishes are what their poor students must order every time they come.

Ye Gui was around, everything was so familiar.

"You've been here?" Zhang Rui asked curiously.

"I've been here before." After a while, Ye Gui replied.

Although Ye Gui's answer was a little inexplicable, Zhang Rui thought he understood, and it didn't matter if he didn't understand, what he wanted to say most now was that code.

That piece of code is one of his project tasks, and he has spent a lot of effort there recently, but it has been a little short of the ideal result, so Ye Gui said the key to it before that Zhang Rui was so excited.

"Your code is for predictions." Ye Gui took the initiative to speak up about this topic.

Zhang Rui nodded, neural networks can do a lot, and what he is doing now is indeed prediction.

"I just saw that result graph of yours, and to be honest, the fitting effect is average." Ye Gui didn't save face for Zhang Rui, he knew that the more true he said, the happier Zhang Rui was.

Sure enough, Zhang Rui nodded heavily: "Although the effect is much better than the original, from the perspective of application, it is generally a bit reluctant." ”

"Because the fitting is not good, you feel that you need to strengthen the training, so you focus the modification on the neural parameters?"

Ye Gui continued: "Although modifying parameters is the most normal idea, from your data set, I don't think you will have a major breakthrough in a short period of time, so it is better to think about it from another angle." ”

"What angle?" Zhang Rui asked excitedly, there is no way to modify the parameters, Zhang Rui knows that this is very slow, but it is better than standing still.

However, this is on the premise that there is no other way.

Preprocess Data. Ye Gui said slowly.

"The pretreatment has been done, but I can't say much about it." Zhang Rui said with some disappointment that he originally thought that Ye Gui would be able to say something very inspiring.

"You certainly haven't done the prep I said." Looking at Zhang Rui's questioning eyes, Ye Gui smiled: "I have a preprocessing method, which is very suitable for doing this kind of waveform data, and the effect should be much stronger than ordinary methods." ”

"A new pre-treatment method?" Zhang Rui asked in disbelief, data preprocessing is a key step in data analysis, and if Ye Gui has a new preprocessing method, then the value is immeasurable.

"Let's not talk about how well your pretreatment method works." After all, Zhang Rui is the elite of the school, and he still has the brains he should have, so he quickly thought of the key and said, "Can you rest assured that you can use this method for me?" ”

Ye Gui glanced at Zhang Rui seriously and said, "If someone else I definitely don't give it, if it's you, no problem." ”

Looking at Zhang Rui's questioning expression, Ye Gui took the lead in asking: "Do you think what you are doing now is meaningful?" ”

Zhang Rui pondered for a while and said: "It is true that what is done in school will be a little out of touch with the real engineering in society, but this is also something that cannot be helped. ”

"Have you ever thought about starting a business?"

Zhang Rui sighed and said, "Of course I thought about it, rather than staying in school like this, of course I would like to do something practical." However, starting a business is not that simple. I know my strengths, good technology, but entrepreneurship not only depends on technology, but also to be able to grasp the market, and have good ideas. ”

Ye Gui was shocked, Zhang Rui in later generations started a business twice, but he failed in these places, Ye Gui thought that Zhang Rui when he was young was that kind of high-spirited, so he didn't consider the actual person, but he didn't expect that Zhang Rui had already thought of this problem at this time.

Ye Gui resisted the urge to ask, 'Then why did you start a business back then', and said: "If you have a good idea, a market, capital, and management, and only let you do technology, can you do your best?" ”

Zhang Rui glanced at Ye Gui and smiled.

"So you're here to poach people, and you want to start a business?"

Dealing with smart people is like this, just a sentence, Zhang Rui guessed Ye Gui's purpose, but Ye Gui didn't hide it, and said: "That's right, I have a good idea now, and everything else can be solved, but there is a lack of a key technical talent, and I want you to do this position..."

Next, Ye Gui explained in detail his idea of making music software, and also clarified the key to it, looking for Zhang Ruilai mainly to let him do the part of the algorithms inside, which are the key to their software being able to compare with other software.

As for the ideas for the algorithms, Ye Guilai provided them, and Zhang Rui was responsible for implementing and debugging the algorithms, and embedding the algorithms into the software kernel.

After listening to Ye Gui's speech, Zhang Rui thought for a while and said: "I don't know much about the music part, but from the perspective of software performance, if you can provide ideas for improving these algorithms, it does have a great advantage." ”

Speaking of which, he returned to the original point, Zhang Rui hesitated for a moment, but still asked: "But is your algorithm really so good?" ”

Hearing Zhang Rui's question, Ye Gui showed a confident smile, what he was most worried about was that Zhang Rui didn't want to cooperate with others on the issue of entrepreneurship, as for the problem of algorithms.

"The pretreatment method I talked about next, you can use it whether we cooperate or not, the only requirement is not to make it public..."

Then, Ye Gui told Zhang Rui about his data preprocessing method, which was a preprocessing method that appeared seven or eight years later, and the principle was to layer the data according to the frequency, so that the algorithm could process the data more carefully.

This idea has now taken shape, but what Ye Gui said is not only detailed and specific, but also an improved version, and the effect is even better.

After listening to this pretreatment method, Zhang Rui came back to his senses for a long time, and said: "I have always been the most powerful one in the department in Shuimu, and Shuimu's computer is the first in China. ”

When Zhang Rui said this, he glanced at Ye Gui again, and then sighed: "I didn't expect that you are the one who is really powerful." ”

Ye Gui looked at Zhang Rui, remembered all the things in his previous life, and said: "I'm not good, I'm just a little smart, you are the real smart person." ”

Zhang Ruiquan was humble when Ye Gui was modest, shrugged and smiled, and then suddenly said loudly: "I have long wanted to do something practical, I took your job, as for the reward, it is the method you just told me." ”

Zhang Rui obviously didn't intend to take advantage of Ye Gui when he said this, because the method had already told him that even if he used it privately, Ye Gui wouldn't care about it.

Zhang Rui didn't know how much money he would lose because of this sentence, but Ye Gui was confident in his own things, so he said: "Let's talk about it when the time comes, let's drink another one, I wish you a happy cooperation!"
