Rebirth: Starting from Lighting Up the Tech Tree

Chapter 116_The Way of Collaboration

With the ability to automatically optimize hyperparameters, Zuo Cheng began a secret "algorithm deduction".

While it's called a simulation, it's actually a rapid verification of various compression strategies with the help of the system's capabilities.

He used the system's capabilities to simulate different parameter configurations and test their impact on model accuracy.

This process would take others months, but he only needs a few days.

Because the system can run countless simulations simultaneously, each simulation is completed in milliseconds.

Two days later, the tireless deduction finally yielded results. Zuo Cheng had found a breakthrough.

Dynamic precision quantization.

Simply put, it allows the model to dynamically adjust its computational precision during inference. Low precision is used for simple tasks, and high precision is used for complex tasks.

This ensures accuracy while keeping power consumption within an acceptable range.

He compiled this technical idea into a document and sent it to Shen Yiming and Fang Ze for review.

"Yiming, do you think this direction is feasible?"

Shen Yiming looked at it for half an hour before returning the call.

"Brother Cheng, this is the right direction." His voice was filled with excitement. "I tested it, and dynamic precision quantization does indeed improve accuracy."

How high can it go?

"89%," Shen Yiming said, "an increase of nearly 21 percentage points from before."

89%.

We are one step closer to the 95% target.

"What about power consumption?" Zuo Cheng asked.

"If we use dynamic precision mode, the MLU270's power consumption can be reduced to 4.8 watts," Fang Ze said, taking the phone. "That just meets the requirement."

4.8 watts.

It was 0.2 watts lower than the target.

This 0.2-watt margin provides greater safety for the solution.

"That's great." Zuo Cheng breathed a sigh of relief, his heart finally at ease.

But he quickly cheered up again.

89% is not enough.

At the review meeting, Lin Jianhua and his group will not give them any room for error.

"It must be over 95%," he said.

There was a few seconds of silence on the other end of the phone.

Shen Yiming spoke up: "Brother Cheng, from 89% to 95%, that's a difference of 6 percentage points. That's an improvement... not easy."

"I know," Zuo Cheng said, "but it's necessary."

Do you have any thoughts?

Zuo Cheng did not answer directly.

He hung up the phone and opened the system panel.

267 points.

This is enough to facilitate another technological integration.

If we combine the capabilities of automatic hyperparameter optimization and model compression optimization...

Perhaps this could lead to a more powerful new ability.

[Technological Integration]

[Cost: 5 points]

Please select at least two blades for fusion.

Zuo Cheng looked at the list of leaves on the panel.

Automatic hyperparameter optimization, model compression optimization, and edge AI inference.

If these three leaves were combined...

Three seconds later, the fusion was complete.

【Successful integration】

[Gaining New Leaves: Adaptive Neural Network Compiler]

Results: Automatically compiles and optimizes neural network models on edge devices, improving efficiency by 1.5x and accuracy by an additional 8%.

Zuo Cheng's heart raced as he looked at the new leaves.

89% plus 8% equals 97%.

It far exceeds the target of 95%.

But he couldn't tell Shen Yiming directly.

Integration is a capability of the system, and he cannot explain its origin.

"Yiming," Zuo Cheng dialed the number, "I have a new optimization idea, give it a try."

What's the thought process?

"I call it 'adaptive compilation,'" Zuo Cheng said. "Simply put, it's about letting the compiler automatically adjust the model structure based on the task type."

"Adaptive compilation?" Shen Yiming was somewhat confused. "That sounds like compiler optimization..."

"Yes, it's compiler optimization," Zuo Cheng interrupted him, "but this optimization is for AI models, not general-purpose programs."

Shen Yiming remained silent for a few seconds. He knew that Zuo Cheng wouldn't speak without reason.

"Okay, I'll give it a try."

---

The next morning, Shen Yiming sent a message.

"Brother Cheng, where are you?"

"At the company," Zuo Cheng replied.

"Come to the lab."

Zuo Cheng pushed open the door and saw Shen Yiming and Fang Ze standing in front of the computer.

Their expressions were strange.

It wasn't frustration, nor excitement, but rather disbelief. It was as if I were witnessing the impossible.

"What's wrong?" Zuo Cheng asked.

Shen Yiming turned his head and looked at him.

"Brother Cheng," his voice trembled slightly, "how did you do that?"

"What should we do?"

"Accuracy rate," Shen Yiming pointed to the screen, "97.1%."

Zuo Cheng glanced at the screen.

97.1%.

It was 0.1 percentage points higher than he expected.

"It's not just accuracy," Fang Ze began, "power consumption has decreased as well."

"How many?"

"4.2 watts," Fang Ze said. "That's 0.8 watts lower than the target."

4.2 watts.

97.1% accuracy.

Both indicators significantly exceeded the targets.

Zuo Cheng remained silent.

He walked to the window and looked at the sunlight outside.

Successful.

The accuracy rate increased from 68% to 97.1%, and the power consumption decreased from 30 watts to 4.2 watts.

This result is enough to silence anyone who doubts them. Lin Jianhua is no exception.

"Brother Cheng," Shen Yiming walked up to him, "How did you do that?"

Zuo Cheng turned his head and looked into Shen Yiming's eyes.

Those eyes were filled with confusion and admiration.

He couldn't tell Shen Yiming the truth.

But he can give a reasonable explanation.

"I'm using a new compiler optimization technique," Zuo Cheng said. "It's called an adaptive neural network compiler."

"An adaptive neural network compiler?" Shen Yiming frowned. "I've never heard of this technology."

"Of course you haven't heard of it," Zuo Cheng smiled. "It's something I designed based on some cutting-edge research papers, plus my own understanding."

"Your own design?"

"Yes." Zuo Cheng nodded. "Accuracy 97.1%, power consumption 4.2 watts. Are these two metrics sufficient?"

Shen Yiming was stunned for a moment, then smiled.

"That's enough," he said. "More than enough."

Fang Ze also came over: "Brother Cheng, how was this compiler designed? I'd like to learn about it."

Zuo Cheng thought for a moment.

He could give Fang Ze some superficial explanations, but he couldn't share the core information.

"We'll talk about the compiler later," he changed the subject. "Right now, the most important thing is to finalize the solution."

"Yes." Shen Yiming nodded. "The review meeting is the day after tomorrow."

the day after tomorrow.

There are only two days left until the review meeting.

"I'll organize the plan," Zuo Cheng said. "You guys continue to refine the test data."

"good."

Shen Yiming and Fang Ze turned around and went back to their computers to start working.

Zuo Cheng stood by the window, watching the two figures from behind.

97.1% accuracy, 4.2 watts power consumption.

This result was enough to leave Lin Jianhua speechless.

But he knew this was just the beginning.

Phase IV of the Sky Dome is just the first step.

A broader stage awaits them in the future.

And he will continue on, step by step. Steadfastly and calmly.

Until I stood in the center of that stage.
