Chapter 490: Confused by the teasing of Song Xiaohua

After dinner, Xu Qingzhou ran to wash the dishes, while Song Yao went to the computer to check the guerrilla algorithm model. Although she wanted to complete it as much as possible by herself, it was not realistic.

You should know that short-selling strategies like this are usually completed by a team of more than five people.

We can talk about academic things tomorrow.

Song Yao's eyes flashed with a strange light. Considering the previous times when this person asked her to be Teacher Song, she thought of some fun things.

Xu Qingzhou came out of the kitchen, wiping his hands, and looked at the cold-looking Schoolgirl Song: "How do we do this?"

Song Yao stood up, gave up her seat, and motioned Xu Qingzhou to sit down.

So proactive today?

Xu Qingzhou was surprised. He probably knew that he would not behave himself, so Song Yao never sat with him when she was busy.

She sat down happily and pulled the school beauty Song into her arms. She was sitting down, and she couldn't let Teacher Song teach her while standing.

Song Yao clicked the mouse with one hand and opened the document, saying: "What you need to do is high-frequency signal synthesis, which is to extract effective trading signals from the raw market data in high-frequency trading, such as price, trading volume, and order flow, filter out noise, identify patterns, and predict the future."

Xu Qingzhou listened carefully and his hands were more honest than usual. He was taking advantage and scoring points. The model this time was indeed very complicated.

He had already grasped most of the content from the previous times, and he simply wanted to tease the school beauty Song.

However, he wanted to be serious, but the girl in his arms was a little different. While she was talking to him, she moved her body and leaned back against his chest.

Xu Qingzhou did not doubt him and adjusted his posture to hold the school beauty Song better in his arms.

“Fourier transform is needed to decompose the time series signal into sine/cosine components of different frequencies and identify periodic patterns.”

In the living room, the girl's voice was light, her logic was clear, and her ideas were well organized.

Xu Qingzhou could easily understand Song Yao's needs.

Tesla's stock price shows repeated rise-pullback cycles within a specific second-level time window, which may be caused by algorithmic trading. Through Fourier transform spectrum analysis, the dominant frequency can be located and trading signals based on cycle phase can be constructed.

The time domain and frequency domain characteristics of the signal can be analyzed simultaneously through the scalable and translated mother wavelet function.

But
Xu Qingzhou's eyes darkened because the school beauty Song in his arms had just said a few words and moved a few times.

"Why do I doubt that she did it on purpose?"

Can.
He glanced at Song Yao's expression.

Serious and serious.

2 minutes passed.

Song Yao was dishonest and leaned on Xu Qingzhou's arms a few more times, her expression still serious:
“Entropy measures the uncertainty or confusion of information. Here, I suggest using a sliding window calculation, with a window of 500 milliseconds, to calculate the entropy of the order flow direction.”

The case is solved, Song Yao must have done it on purpose.

But Xu Qingzhou was already a little confused. The way he kept rubbing against her, especially the way he remained serious and aloof, gave him a sense of excitement.

“Use wavelet coefficients, entropy values, and Fourier spectrum as input features to train the LSTM model to predict price direction”

Song Yao didn't continue talking, her heart was pounding.

"and then?"

Xu Qingzhou hugged the school beauty Song's slender waist tightly, still feeling unsatisfied.

"Then?"

Song Yao blinked, tried to calm her breathing, and pried open the fingers around her waist one by one, saying word by word: "You should work hard."

After saying that, she stood up with her computer and sat down opposite Xu Qingzhou.

"."

Xu Qingzhou took a deep breath, adjusted his sitting position, and glanced at the girl opposite him with resentment. Seeing Song Yao's big innocent eyes, he could only sigh.

"I'll take a shower and calm down."

Revenge, this is naked revenge.

She only cares about taking off and not landing. This girl is a bad person. At the table, Song Yao looked up at Xu Qingzhou who went into the bathroom, snorted, and thought to herself, "You deserve it. Who told you to make me angry all the time?"

but
Thinking of the scene where the two of them were close together just now.

Her cheeks felt a little hot.

Not to mention Xu Qingzhou, even she had some strange feelings and inexplicably wanted to get close to Xu Qingzhou.

Song Yao, oh Song Yao, you have fallen.

In the past, I never would have thought that I would deliberately rub against a boy's arms.

Song Yao sighed inwardly.

10 minutes passed.

After taking a shower, Xu Qingzhou finally calmed down. He turned on his computer and looked at the document Song Yao sent him. It was quite troublesome to actually do it, as it involved various economic models and extremely complex algorithms.

He asked, “When will you give it to me?”

"Before November."

Song Yao regained her composure after a while.

“That’s still plenty of time.”

Xu Qingzhou nodded slightly. It would not be a problem to make this thing in a month. "Let's just start with a small step today."

11 pm.

Song Yao had finished her shower and came out. She secretly glanced at Xu Qingzhou, sat down on the sofa, and secretly grumbled, "There's a beautiful woman standing in front of you, but you're only focused on academics."

"Huh~"

Xu Qingzhou looked up curiously. Was School Beauty Song secretly looking at him?
But when he looked over, Song Yao was already holding a tablet and looking at information.

Song Yao observed Xu Qingzhou out of the corner of her eye, pulled her nightgown up, revealing a part of her thigh, nodded with satisfaction, and continued to read the information. Based on her understanding of this guy, he would definitely take the bait.

Xu Qingzhou lowered his head and calculated for a while, then looked up and saw the girl lying on the sofa, her white and slender thighs folded together, and her tender feet were gently shaking.

"This girl is fishing."

He was sure of what he was thinking.

"Oh, are you using this to test the cadres?" Xu Qingzhou chuckled in his heart, closed the notebook, and still wanted to test his own weaknesses.

crunch~
Er Miao tilted his head to look at the sofa, wondering what was going on. When he saw the familiar scene, he turned his head away and fiddled with the cat toy.

Xu Qingzhou, who was pinned down on the sofa, felt hopeless.

got used to.

10 month 1 day.

The whole country of Xia celebrated with great excitement.

Because from the 1st to the 8th, the names of Nobel Prize winners will be announced one after another.

On October 10, the Karolinska Institute in Sweden announced that the Nobel Prize in Physiology or Medicine was awarded to James Allison and Tasuku Honjo.

The Prize in Physics, Chemistry, and Physiology or Medicine are worth looking forward to.

Awards such as the Literature Prize, the Economics Prize, and especially the Peace Prize, are highly operational and not very exciting.

However, despite many people criticizing it now, the overall value of the Nobel Prize is self-evident. At least, no award can surpass the Nobel Prize at present.

It has not yet reached the point where people say that the Nobel Prize is something that can only be viewed and laughed at.

The Prize in Physiology or Medicine is a warm-up.

Xu Qingzhou was not so expectant. If nothing unexpected happened, the list of winners would be similar to that in his previous life. He was more focused on the experiment.

With the help of two days over the weekend, he optimized the model again and decided to reduce the surface roughness to RMS=0.8 nm to reduce the graphene transfer breakage rate.
