94: From Technological Warfare to Space Empire

"Hmph, that's easier said than done."

"Using machine learning to process signals? The computing power required increases exponentially with each additional segment of data a supercomputer can process!"

"Where did we get that kind of supercomputer?"

As soon as Lin Yu finished speaking, Professor Wang, who had previously expressed some dissatisfaction with Professor Song, immediately began to question him.

Professor Wang places more emphasis on practice than theory.

In his view, there are countless theories, but when it comes to practice, a considerable portion of them will only become stumbling blocks.

The old society, where Confucius wrote hymns every year and established surrender documents every day, is not even a hundred years old. Practical experts like Professor Wang are extremely averse to this kind of empty theoretical talk that paints a rosy picture.

"Kid, if you've got real skills, show them to us!"

"Don't tarnish your teacher's reputation by talking about things that are theoretically possible but practically impossible!"

Professor Wang's words were sharp, but not harsh.

Lin Yu was not afraid of such pressure at all.

The only sound in the conference room, filled with senior engineers, was the hissing of the heating pipes.

Lin Yu picked up a piece of chalk, stood at the front of the stage, quickly wrote the title "Machine Learning Signals," and then immediately launched into a profound statement, using his sharp pen to cut off any doubts:

"The logic behind the interference of the American SA policy is twofold."

"One layer is random high-frequency sound, and the other layer is a systematic shift in orbital parameters."

This is something all the professors present already know; it's not very informative.

Whether it's casual or solemn.

The professors' reactions varied, and all of them were observed by Professor Song.

Professor Song sat in the corner, added two pieces of rock sugar to the tea in his enamel mug, and started watching the show.

He trusted his students precisely because Lin Yu never boasted.

Lin Yu continued writing:

"The former relies on statistical modeling for separation, while the latter relies on celestial mechanics for back-calculation correction. I'm sure you've all anticipated these two points as well."

Professor Zhou, who had previously relied on algorithm research, nodded.

"Using Kalman filtering can reduce the accuracy to 50 meters, but that's about it."

"Do you have any new ideas?"

When it came to this, Lin Yu knew it was time to bring out the real deal.

"Chief Engineer Lin, please allow me to have the security guards move my supercomputer here."

With permission from higher-ups, two somewhat young security guards moved the supercomputer that Lin Yu had already notified to bring to the conference room from the lobby on the first floor.

"Japan cannot develop artificial intelligence using neural networks."

"But one of the greatest equations of the 20th century—the Bayesian algorithm—can."

Professor Zhou, who had expected Lin Yu to have some profound insights, shook his head in disappointment upon hearing that it was about the Bayesian algorithm.

This thing has been neglected by the academic community for almost a century; if there were any real evidence, it would have been unearthed long ago.

This kid is now saying that this lousy equation is the greatest equation of the 20th century? Young people are really clueless.

Professor Zhou was just about to get up and leave when he heard Lin Yu continue speaking:

"Kalman filtering is too dependent on initial parameters."

"Over the past 10 hours, I used a hybrid model of Bayesian algorithm and backpropagation to enable AI to autonomously learn the distribution pattern of SA noise, and I also enabled AI to run all the data of satellites in space orbit over the past few years."

That's why I was a little late.

"Now, let's have a live demonstration!"

Upon hearing that Lin Yu was going to give a live demonstration, Professor Zhou paused in his tracks, adjusted his reading glasses, and stopped.

He wanted to see what tricks this young man could pull off with the Bayesian algorithm!

Lin Yu signaled to the staff to connect the conference room's monitor to the Cray supercomputer. Instantly, a dense stream of data appeared on the screen. As Lin Yu typed a series of commands, the supercomputer's air-cooling system suddenly accelerated, emitting a deep hum.

Then the GPS satellite navigation map was brought up.

Artificial intelligence?!

The professors in the room all sat up straight, eager to see what Lin Yu meant by artificial intelligence.

In this day and age, no country has truly developed artificial intelligence.

There are very few supercomputers.

The Soviet Union, the elder brother, also suffered a major setback in the arms race due to AI!

Can this kid really invent artificial intelligence all by himself without relying on anyone?

After the navigation map finished loading, Lin Yu pointed to the red dot jumping on the screen and said:

"This is the currently synchronized civilian GPS signal."

"Initiate noise reduction and track correction procedures now."

Everyone's eyes were fixed on the screen. The red dots that were originally scattered within a hundred-meter range were gathered together as if by an invisible hand. The chaotic peaks on the band chart were flattened one by one, and the distorted curves gradually became smooth.

The numbers representing the error began to drop rapidly.

117米、89米、53米、27米、12米。

The huge red dot just moments ago was quickly compressed into a spot of light in the blink of an eye.

The next moment, gasps of shock filled the conference room!

None of the engineers in the lab didn't understand what this meant.

That's a change in the precision of the signal!

Professor Wang slammed his hand on the table and stood up, while Professor Zhou's hands trembled slightly as he tried to see clearly through his reading glasses. Chief Engineer Lin's mouth dropped open, and he didn't even notice the cigarette butt that fell from his mouth onto his clothes.

Professor Song, who had always trusted Lin Yu, spat out a mouthful of hot tea. He had thought the kid would only offer a feasible solution, but he hadn't expected him to actually produce a physical product.

"Professors, please take a look, this is the proposal I submitted..."

Before Lin Yu could finish speaking, a group of professors disregarded their manners and rushed onto the podium.

Professor Zhou went to investigate whether the signal source had been tampered with.

Professor Wang picked up the mouse to check if it was an animated demonstration.

Chief Engineer Lin then directly called out to the security guards at the door:

"Guards! Guards!"

Chief Engineer Lin's startled shout startled the security guards at the door, who immediately broke down the door and entered.

But then he was met with a stern lecture from Chief Engineer Lin, who was already overwhelmed by this enormous surprise:

"Keep your voice down when you come in, don't kick the door down!"

"Wang Jianjun, you guard the main gate and do not allow anyone to enter or leave! Liu Gang, go and tell the military leaders to drop everything and come to this conference room immediately!"

Chief Engineer Lin, with a serious expression, grabbed Liu Gang by the collar and said:

"Remember, after you arrive at Beihang University today, don't reveal a single word about anything you see. Just call the leaders over. Don't say anything else."

The young guard nodded, and then Chief Engineer Lin patted him on the shoulder before the guard ran off.

After everything was arranged, Chief Engineer Lin couldn't wait to join the crowd of onlookers.

At this moment, all 34 professors gathered on the podium, in front of the screen, in front of the supercomputer, and around Lin Yu.

"Xiaoyu, where did you get this superb?"

"Xiaoyu, how did you develop this artificial intelligence?"

"Xiaoyu, how did you achieve the reverse processing of noisy signals using the Bayesian algorithm?"

"Xiaoyu, do you still want a teacher? Just say the word, and you can leave your sharp-tongued tutor behind. Come work for me!"

"How can the Bayesian algorithm be used in this way? Is this really the Bayesian algorithm?"

Lin Yu was overwhelmed by the professors' sudden enthusiasm and questions.

Aside from the one who wanted him to change teachers because Professor Song was fighting and he didn't need to get involved, Lin Yu answered all the other professors' questions in a flurry.

Subsequently, the professors' test results came out.

"...It did indeed bypass the US military's 1023-bit Gold encryption, reducing the accuracy to 1.2 meters."

Professor Zhou's voice trembled as he explained; after the technology was blocked, he was the one who worked tirelessly on his research.

"...The algorithm's filtering delay is only ten microseconds, which is almost negligible in the short term."

Professor Wang looked at this astonishing error and felt as if he had fallen into some kind of dream.

Finally, Professor Song reacted and shouted:

"What are we waiting for? Quickly send a telegram to the aerospace tracking and control station! Tell them to get ready, we'll go straight there for the on-site test soon!"
