I Exchange For Black Technology By Blowing Up The Bully

Chapter 341 You’Re Sweating Profusely, Ji Tianhe

"It can't be done." Lou Jinghui smiled helplessly, "My intuition is an illusion, the new mathematical model does not exist!"

"I feel the same way." Ji Tianhe nodded, "Every road is impassable."

Song He frowned, "Show me your derivation process."

The three people moved in unison, took out the computer from the computer bag and turned it on.

Afterwards, three computers were placed side by side on the table, each displaying a copy of the derivation process.

Song He carefully looked at the derivation of the two master disciples. They were both very strong. They took more than ten different routes, their logic was rigorous and their thoughts were clear, but they all reached dead ends without exception.

"Are you sure you have tried all the roads?" Song He asked.

"OK!" The two disciples said in unison.

"Then what are these for me?"

As Song He spoke, he moved his computer mouse and quickly slid down.

One kind of derivation appeared one after another. The two master disciples came over and stared at the teacher's computer. More than twenty derivation ideas appeared one after another. There were several routes that the two of them had never tried before!

Ji Tianhe's eyes were surprised, and he thought carefully about the unfamiliar derivation. The teacher was right, the possibilities are indeed endless!

Lou Jinghui was shocked. He, who was always talkative, was at a loss for words for a moment!

He was very conceited in the field of mathematics. He originally thought that Song He's expertise was in biology and his mathematics skills should be far inferior to him.

But at this moment, looking at the tricky deductions on the screen, Lou Jinghui suddenly realized that Teacher Song He’s mathematical attainments were beyond imagination! For a moment, I couldn’t tell the depth!

Lou Jinghui's hands suddenly trembled, like a Parkinson's attack!

"What's wrong with you?" Song He was startled.

"I'm sick, teacher, your deduction has induced encephalopathy in me and I can't stop it!" Lou Jinghui's eyelids blinked wildly, his hands shook even more, his face turned red, and he looked like he was about to self-destruct.

"Jing Hui, you can't do it, then let's get started!" Song He put his hands on the keyboard, "I thought of a new idea on the way here. If there's a play, I'll write it out and let's promote it together!"

Before he finished speaking, he tapped his hands wildly and listed a large number of derivation processes on the screen!

Lou Jinghui's hand trembled significantly less, his eyes were fixed on the screen, and his brain quickly entered high speed. His whole body was like a hot pressure cooker, and he needed to rely on thinking to constantly deflate and reduce pressure.

Ji Tianhe opened the calculation software on his computer and laboriously checked the derivation process to catch up with the teacher's progress.

"We started with the basic inference of Kalman filtering." Song He said, "The first few sets of data are set as state transition matrices, and the last few sets of data are control input models..."

"Teacher, you are wrong in this step. According to the Kalman filter, the noise obeys the Gaussian distribution with zero mean!" Lou Jinghui suddenly reached out and poked at the screen.

"Rigid! We are analyzing drug molecules, not irregular external disturbances!" Song He criticized.

Lou Jinghui's hand tremors disappeared instantly. The teacher's words drove his brain speed to its peak, and the disease was suppressed.

But the disease was only suppressed for a few seconds, and the shaking of his hands recovered.

"I understand, I understand!" Lou Jinghui was excited, "Teacher, your idea is right! I am too rigid. The next step is to map the real state space of the system into the observation space, construct an initial covariance matrix, and then perform data embedding. set!"

Song He was surprised, and his hands typing on the keyboard couldn't help but stagnate slightly. Lou Jinghui's reaction speed was so fast that he caught up with his own thoughts in an instant, and even surpassed him by a little!

He is indeed a top student, so terrifying! My brain is as powerful as if I had taken a mental arithmetic capsule!

No, you can’t show your timidity in front of the students!

Song He lowered his head to eat glutinous rice balls and secretly stuffed two mental arithmetic capsules into his mouth.

The discussion became heated, and the corner of the restaurant was filled with the sound of three people chasing each other:

"The uncertainty will increase as iterations proceed. Teacher, you must eliminate the error variance of the estimated state!"

"No, at this point we can no longer use Kalman gain. We must find another way. Let's try jumping directly to the optimal estimated covariance matrix!"

"Teacher Song, I feel like this won't work. The sign of the covariance matrix cannot handle the enhancement and weakening of drug molecules. Can you try to construct a likelihood function?"

"Gram-Schmidt orthogonal, try this first. After all, the last few data of the drug molecule are all linearly independent input vectors, but what definition is used? Two norm?"

"The second norm doesn't work, we have to go around it! Wait a moment, teacher, I remember there is a related question at the Princeton Mathematics Annual Meeting!"

The three teachers and students were completely immersed in the calculation, each typing on the keyboard and croaking non-stop.

Lou Jinghui looked for relevant papers that could break through the obstacles, Song He was responsible for the overall attack and writing steps, and Ji Tianhe was busy checking the calculations, looking for inconspicuous loopholes.

During the long battle, the derivation steps on the screen became longer and longer, like a plant watered with Fukushima water, growing into a completely unfamiliar appearance!

It was so unfamiliar. The three of them had never seen similar mathematical analysis methods. They were half nervous and half excited.

Pushing and pushing, Song He suddenly stopped.

Almost at the same time, Lou Jinghui also stopped, leaving only Ji Tianhe still typing on the computer.

"Wait a minute..." Song He leaned forward, "We seem to be done!"

Lou Jinghui was sweating profusely and slumped in his seat. He raised his hand and glanced at his watch, "Two forty! Been busy for about two and a half hours!"

"Ah? Is it finished?" Ji Tianhe was surprised and leaned over to look at the screen.

Song He smiled, moved his fingers a few times, and finally typed three lines and hit Enter!

"It's really finished!" Ji Tianhe was also excited, "Would you like to substitute a set of data and give it a try?"

"I've done the math in my head and it's feasible!" Song He said firmly, "You can write a paper now. You two can write it. The new mathematical tool for drug molecules can increase the data processing speed under specific conditions by five times!"

"Choose a name?" Lou Jinghui suggested, "How about Song Ji Lou Analysis Method?"

Song He didn't express his position, his eyes narrowed slightly, and he turned to look at Ji Tianhe.

Ji Tianhe shrank his neck, "I haven't made any contribution, so I won't be named, so you can hang on!"

"How can that work?" Lou Jinghui glared and said, "During the derivation, you pointed out four loopholes. Every time you fixed the loopholes, you avoided hidden dangers later! Without you at the rear, we would have rushed into the ditch when we charged from the front!"

"No, no!" Ji Tianhe waved his hands repeatedly and explained uncomfortably, "The work I did is insignificant, I really have no name!"

"No!" Lou Jinghui was anxious.

"It's getting late, I'm going back to bed first!" Ji Tianhe stood up in a panic, packed his computer bag and left, "Goodbye, Teacher Song! Goodbye, Brother Lou!"

"Are you hiding something from me?" Song He stared at him with a smile.

Ji Tianhe's movements froze for an instant, and he smiled under his mask, "No! I don't have anything to do..."

"Tan Xi is your boss, right?" Song He asked.

Ji Tianhe trembled slightly, his limbs stiffened for a moment, as if he had been hit by a bullet in the heart!

He originally stood up, but then sat down slumped and helplessly, his face was extremely frightened, like a prisoner caught in a war.

Lou Jinghui blinked beside him and realized that something was wrong in the atmosphere.

He looked at the teacher and then at Ji Tianhe, then pressed his hands on the keyboard sensibly, and began to write the paper. He wrote quickly and listened secretly with his ears erect.

"You... have known this for a long time?" Ji Tianhe asked in a low voice.

"No, I just tested you, but it seems you can't stand the test." Song He smiled warmly.

Ji Tianhe's face turned pale, like a prisoner being led to a wasteland covered with blood.

"You have been scared to look around tonight. Your face is covered tightly. You must be afraid that someone will see you sitting at the same table with me." Song He said softly.

"Why are you afraid? It means you are my enemy camp, and I only have one enemy in Ruoqiang."

"When I introduced myself, I was vague about what you were doing. No results have been produced for ten years, which is very consistent with Professor Tan Xi's style. I guess your results have been basically taken over by Professor Tan Xi, right?"

"Now that the results are out, you don't dare to sign. It's just because you're afraid that your name and mine will be put together and the matter will be exposed."

"Am I right?" Song He said in a leisurely tone.

Ji Tianhe was sweating profusely on the spot.
