Rebirth: Starting from Lighting Up the Tech Tree

Chapter 115_The Power of the System

At 2 a.m., the entire 402 building fell silent.

Zuo Cheng sat alone in his office, the computer screen in front of him lit up, but his attention was not on the screen.

He stared at the countdown timer in the lower right corner of the system panel.

3...2...1...

[Cooling of the technology radar is complete]

Zuo Cheng took a deep breath, a certain light flashing in his eyes.

He needs a key technology: automatic hyperparameter optimization.

This is a cutting-edge direction in the field of AI, which enables models to automatically find the optimal parameter configuration and significantly improve accuracy.

With this technology, it becomes possible to increase the accuracy rate from 68% to over 90%.

The technology radar is activated.

The scanning range is 30 meters.

Testing in progress...

Three seconds later, a prompt popped up:

[No personnel detected within a 30-meter radius; unable to scan technical information]

Zuo Cheng was stunned for a moment.

(Please remember the website 202s.tw for the fastest chapter updates.)

He forgot one thing. At two in the morning, he was the only person in the entire building.

Shen Yiming went home.

Scanning technology requires the target object to be present.

Zuo Cheng rubbed his temples. It seemed he would have to wait until tomorrow.

He gently turned off the system panel and leaned back in his chair. The office was quiet, with only the low hum of the air conditioner.

He was going to bring Shen Yiming to the lab first thing tomorrow morning.

Use a plausible excuse to get him to cooperate with the scan.

"I need you to help me test an algorithm framework."

Zuo Cheng came up with an excuse.

It's not about making him run code, it's about making him "share" the knowledge in his mind.

This was a strange statement, but he believed Shen Yiming would cooperate. In fact, Shen Yiming had never let him down.

After all, they share the same goal.

---

Zuo Cheng arrived at the company at seven o'clock the next morning.

He called Shen Yiming: "Yiming, come to the company. There's a test that needs your cooperation."

"So early?" Shen Yiming's voice was still sleepy.

"It's very important," Zuo Cheng said. "It's related to the success or failure of the Sky Dome Phase IV project."

There was a two-second silence on the other end of the phone.

"Okay, I'll be right there."

Half an hour later, Shen Yiming appeared in Laboratory 402.

He still looked a little sleepy, but his spirits had lifted.

"Brother Cheng, what kind of test?" he asked.

Zuo Cheng closed the door and drew the blinds.

"Yiming, I need you to help me test an algorithm framework," he said. "Not to run code, but to 'share' the knowledge in my head with me."

Shen Yiming was stunned.

"Sharing? What does that mean?"

"It means exactly what it says," Zuo Cheng said. "You express your experience and intuition about tuning AI models in some way."

Shen Yiming was even more confused.

"Brother Cheng, how do I express something like this?"

Zuo Cheng did not answer. He walked up to Shen Yiming.

"Yiming, trust me," he said. "I know it sounds strange, but I have my ways."

Shen Yiming looked into Zuo Cheng's eyes.

There was something in there that he couldn't understand.

It's not madness, not stubbornness, but a kind of unwavering faith.

"Okay." Shen Yiming nodded. "I'll cooperate with you."

Zuo Cheng breathed a sigh of relief.

He opened the system panel and selected Technology Radar.

[Technology Radar Activated]

[Target: Shen Yiming]

[Scanning in progress...]

Zuo Cheng looked at Shen Yiming as if he were looking at an ordinary person. But the information on the system interface was completely different.

[Target brain activity detected]

[Extracting...]

[Automatic Hyperparameter Optimization Algorithm × 1]

Scan complete. A stream of data flashes on the screen.

Immediately afterwards, a copy prompt popped up:

[Replicable technology detected: Hyperparameter automatic optimization algorithm]

[Copying costs: 10 points]

Current points: 277

[Copy or not?]

Yes.

[Copy complete]

Current points: 267

[New blades acquired: Automatic hyperparameter optimization]

Zuo Cheng looked at the newly appeared leaves on the panel and a slight smile appeared on his lips.

Successful.

"Brother Cheng?"

Shen Yiming's voice interrupted his thoughts.

"What's wrong?" Zuo Cheng came back to his senses.

"You were acting strange just now..." Shen Yiming hesitated for a moment, "...you seemed a bit odd."

"That's weird?"

"It's just..." Shen Yiming couldn't find the right word, "...like he was in a daze."

Zuo Cheng felt a pang of anxiety, but remained outwardly calm.

"Maybe I'm just too tired." He changed the subject, "Yiming, what are your insights on automatic hyperparameter optimization?"

Shen Yiming was taken aback, clearly not expecting Zuo Cheng to ask this: "Automatic hyperparameter optimization? Why are you suddenly asking this?"

"Just asking."

"Oh." Shen Yiming thought for a moment, "Automatic hyperparameter optimization is a hot topic in the field of AI. Traditional hyperparameter tuning requires a lot of manual trial and error, which is very inefficient. If AI can automatically search for the optimal parameter configuration, the accuracy will be significantly improved."

"How much can it improve?"

"It's hard to say," Shen Yiming said honestly. "Theoretically, it could improve performance by 5 to 10 percentage points. But that requires a sufficiently powerful algorithm framework."

5 to 10 percentage points.

68% plus 10% equals 78%.

Not 95% yet.

But at least, the direction is right.

"Yiming," Zuo Cheng said.

"Um?"

Give me three days.

Shen Yiming was somewhat surprised: "Three days? For what?"

"We're validating an algorithm," Zuo Cheng said. "If the validation is successful, the accuracy can be improved to over 90%."

Shen Yiming's eyes lit up.

"Over 90%? Really?"

"You'll find out in three days," Zuo Cheng said. "Until then, you and Fang Ze continue to optimize the chip design."

"Okay." Shen Yiming nodded. "I believe you."

He turned and left the laboratory.

The moment the door closed, Zuo Cheng reopened the system panel.

[Technology Tree Status]

- Branches: Communications Engineering, Aerospace Communications, Internet of Things, AI (4/7)

Points: 267

- Leaves: 40

- Added: Automatic hyperparameter optimization

267 points.

It's 10 points less than before.

But those 10 points led to a breakthrough in a key technology.

Automatic hyperparameter optimization.

Now, he needs to find a way to increase the accuracy rate from 78% to over 95%.

It's still 17 percentage points short.

Perhaps we could try integrating technology.

By combining the capabilities of multiple blades, a stronger new capability can be generated.

However, the success rate of fusion is not 100%. If it fails, the 5 points will be wasted, and you will have to wait another 48 hours for the cooldown to complete.

How many days are left until the two-week deadline?

Zuo Cheng opened the calendar and glanced at it.

There are 11 days left.

enough.

He has plenty of time to try.

Zuo Cheng turned off the system panel and started working in front of the computer.

The accuracy rate is over 90%.

No, his goal is over 95%.

This is not just about meeting the review requirements, but also about leaving Lin Jianhua speechless.

Let those who question them shut up completely.

He wants to do things to the extreme.

This is the source of 402's confidence.
