Don't look at Fu Yingyue's age, but to adapt to Mr. Liu's style, it takes at least twenty or thirty high-intensity exercises.

Mr. Liu is called an experienced, highly developed, and comprehensive knowledge, which is much better than those professional players who paddle around.

It is normal for those with a lower limit to lose to those without a lower limit.

Fang Xiaowu didn't get involved, and let them communicate slowly, so Mr. Liu gave a task to the former exclusive customer service.

"To think about a big house, at least 300 square meters, the bedroom should be large, the bed should be special, and the rest of the requirements are as follows...... Balabala......"

Fu Yingyue's ears were red, looking at a little girl who was six or seven years younger than herself, but she didn't dare to say anything, feeling that Zhen Nima was strange!

"You pick the house, I pay for it, write our names on the real estate certificate, and then you are responsible for the decoration, when it is installed and when it will give you a chance to surpass the ordinary...... Just sauce, you have to hurry up, take care of you Sister Yueyue!"

Dizzy!

Mr. Liu, is your so-called "beyond the ordinary" the same thing as what I think? !

If yes............ I didn't want this opportunity!

Fu Yingyue was almost insane by a killing stick, and as soon as Liu Lianlian left, she immediately came over to ask Fang Xiaowu for advice.

"Uh...... Yes...... Hmmm......"

The little fifth brother was as if he had just woken up, and after a while, he suddenly said: "You don't need to buy the house, you tell Mr. Cheng, there are a few building kings in the second phase of the prosperous Huanian, and the best one is enough for us." ”

Fu Yingyue was stunned for a long time, took deep breaths repeatedly, and finally controlled her emotions that were about to explode, and said coldly: "The problem is, I don't want to use it with 'you'. ”

The little fifth brother patted her on the shoulder and comforted her in a good voice: "Don't worry, you will change your mind...... Get to work first. ”

Oh hey, I'm so grumpy, I really don't believe it!

Fu Yingyue sneered, then shook her long hair arrogantly and turned to go upstairs.

Little Fifth Brother?

The little fifth brother flashed people directly and went to find Yang Minglong and Bai Wushuang to stir up the base.

There are so many people who don't believe in evil, is it necessary to be more useless?

I can really hold on for a week, brother, you are a man!

……

Same-sex people who can find a common language will inevitably become friends, and if they find a huge common language in the areas they are most interested in, it is a good friend.

When Fang Xiaowu opened Yang Minglong's door with the password, the pair of good friends were sleeping together.

The trouble is that the two of them are facing each other's heads and feet, hugging each other's big feet, and the little fifth brother thinks it tastes good when he looks at it.

"Hey, wake up! Your hard drive is burning!"

I couldn't bear it, and the little fifth brother could only wake them up.

"Damn!

Yang Minglong rolled over and got up, almost scared to pee.

Relaxed and happy, they came to their senses, and the three good friends happily began to review the results.

"Xiao Wu, come and take a look at my improved Apriori algorithm based on the entropy weight method, this part is particularly easy to use in data mining, I collected data from the platform and tried it, and it can optimize the accuracy by 8~11%!"

Fang Xiaowu sat on the engineering chair with great interest, read the code for half an hour, and suddenly frowned.

"Where is the original paper for this algorithm?"

"Got a problem?" Yang Minglong's mouth twitched, and he quickly flipped out the paper on another screen, "Here, it is one of the series of studies by Dr. Harnes of Cambridge, and github does not have an open source implementation, so I made it myself." ”

"I'll take a look first. ”

Little Brother began to read back and forth between the English paper and the code.

After a long time, he groaned: "A lot of implementation details are not given in the paper at all, your overall model is very good, but many custom layer structures are too complex, and there are a few special loss functions that are a bit biased, so the final LOSS curve convergence is not quite right......"

Yang Minglong was a little ashamed, but more of admiration, and slapped him.

There is a layer in the paper, Dr. Hahns has brushed it over, and I don't understand the mathematics of that layer too much...... Ma Dan, the previous mathematical foundation is not enough at all!"

"It's already good. ”

Of course, Fang Xiaowu wouldn't blame him, and Bai Wushuang immediately comforted: "Brother Long, it's already remarkable that you can reproduce a new paper to this extent, I can't even read it......

In the end, Bai Wushuang suddenly glanced at Yang Minglong, and then turned his head to look at Fang Xiaowu......

Boom!

Involuntary swallowing and spitting.

It's also a freshman, why can't I read it?!

Fang Xiaowu was very focused, didn't notice that something was wrong with the two of them, and said to himself: "Lao Yang's work is very valuable, and now there is a very bad atmosphere in the industry, that is, engineers basically only change the parameters, or adjust the feature diagram, change the model, add some skills, and even complete the work." ”

"In fact, to be a good data engineer, deriving formulas from the bottom is a necessary skill, and if you don't know enough about the algorithm, you have to make a lot of detours just to adjust the parameters, wasting time and energy......"

Yang Minglong and Bai Wushuang glanced at each other again, and sighed helplessly and sadly.

"Yes...... Teacher Fang......"

The little fifth brother in a state of concentration basically doesn't pay attention to irrelevant details, checks papers while reading fragments, and quickly finds the problem.

"Look here!"

"Nothing to do with physics, in information theory, entropy is a measure of uncertainty. The entropy-weighting method is an objective empowerment method. It's very complicated, and the second step in the calculation step is to normalize the broken matrix to get the normalized judgment matrix, which you ...... here."

Yang Minglong hurriedly cheered up and listened to Teacher Fang's lecture.

Fang Xiaowu had just seen the relevant algorithms in the book "Statistical Essentials", and he specially supplemented the mathematical knowledge to deal with this problem, which was so simple that he didn't want it.

But...... Yang Minglong has no plug-ins!

After an hour, Yang Minglong finally understood what went wrong, what the mathematical basis was, and what the implementation details were, and then started to fix the code.

Bai Wushuang scratched his ears and scratched his cheeks when he heard it, but he couldn't understand it, and seeing that Fang Xiaowu was finally free, he immediately took out a question and asked for advice.

The little fifth brother patiently talked to him for a while, but found that it didn't make sense at all......

"Yes, fat man, the class you are missing is not a star, this is not a problem of language, it is a problem of mathematical foundation. Or you should minor in math!"

Bai Wushuang suddenly became very sad, and his little short hand held his belly one by one.

"Little Fifth Brother, what can I do to help you like this...... Mathematics must be learned, but after four years, you've long since left me behind......"

Huh, this kid was hit hard by me?!

The little fifth brother was surprised and amused, patted his big belly hard, and scolded: "You study your hard! Do you plan to let the boss of Yushu Linfeng write the code myself? Learn R and Python well, you have a chance to play!"

“……”

It makes sense, but when the fat man thinks about it, he always feels that something is wrong.

I code day and night, what about you?

Suddenly thinking of Han Xiyi, who had long legs against the sky, the fat man suddenly realized what the answer was, so he became more and more depressed......
