Chapter 41 Is this something a human could do?
The next morning, Lu Feng had just pushed open the door to Laboratory 302.
There was only Zhou Mingyuan inside. He had huge dark circles under his eyes, and he was yawning at the screen, with a deflated backpack next to him.
Hearing the noise, Zhou Mingyuan turned his head.
"Junior brother? Why are you up so early today too?"
"Come run some errands." Lu Feng pulled out a chair and stuffed his backpack into the desk drawer.
"Have you eaten?" Zhou Mingyuan rubbed his messy hair.
"have eaten."
"Then you go ahead and get busy. I'm here early, and my stomach can't take it anymore. I'll go to the cafeteria and get something to eat." Zhou Mingyuan stood up and stretched. "Damn it, I still have more than a dozen sets of data to calculate today. Just thinking about it gives me a headache."
Zhou Mingyuan staggered out the door.
Lu Feng pressed the power button on the high-end desktop computer.
The case fan emitted a slight hum, and the system booted up almost instantly.
i7 processor, 32GB RAM.
This configuration would have been top-of-the-line in 2012.
Lu Feng plugged in the USB drive and copied the source code of "University Data Sauce," which he had only half-finished writing last night, into the hard drive.
Configure the Python runtime environment and install the necessary third-party libraries.
Fingers tapped on the keyboard, the crisp sound of the keys echoing in the empty laboratory.
The bottleneck that was stuck on the preprocessing module last night was easily solved with this machine.
With ample computing power, Lu Feng's thinking was completely opened up.
He began to reconstruct the core algorithm engine.
Fourier transform, wavelet analysis, principal component analysis—complex mathematical models are transformed into concise code logic.
Redundant loops were eliminated, and the logic of memory access was optimized to the extreme.
An hour later.
Lu Feng typed the last line of UI code and pressed Enter.
A simple window with a gray background and a white border pops up on the screen.
The interface is extremely simple. The left side is the data import area, the middle is the algorithm selection drop-down menu, and the right side is the result output and chart display area.
At the top hang five large characters: University Data Sauce.
The name itself gives off an unreliable, makeshift vibe.
Lu Feng leaned back in his chair and stretched his aching wrists.
The framework is set up, and the algorithm has been integrated.
Now all that's missing is a sufficiently large dataset for testing.
Just then, the laboratory door was pushed open.
Zhou Mingyuan walked in, holding half a piece of boiled corn with pitted edges in one hand and a cup of soy milk in the other.
"Phew~ The corn in the cafeteria is still the most filling."
He pulled out a chair, sat down, put the soy milk on the table, and opened MATLAB on his computer.
Looking at the densely packed engineering documents on the screen, Zhou Mingyuan took a big bite of corn, his face full of resistance.
"Senior brother, do you have any test data that needs to be processed?" Lu Feng turned around and asked.
Zhou Mingyuan stopped chewing corn.
"Yes, what's wrong?"
Send me a copy.
"What do you need this for?" Zhou Mingyuan swallowed what was in his mouth, somewhat puzzled. "This is the measured vibration data from the second phase of our gear project. It contains a lot of non-stationary noise, it's a mess."
"I just wrote a small tool and want to test it with real data."
Zhou Mingyuan was stunned.
He turned around and looked Lu Feng up and down.
"You wrote this? What tool did you use?"
"A data processing software."
Zhou Mingyuan was stunned after hearing this.
"Your junior colleague is learning software development?"
"I just learned it last night."
Zhou Mingyuan almost spat out the mouthful of soy milk he had just sipped.
He coughed violently twice and pulled out a tissue to wipe his mouth.
"You just learned it last night? And you've already written the software today?"
He had a "you're kidding me" look on his face.
When it comes to programming, everyone starts with "Hello World" and gradually gets the hang of it after being tormented by various bugs.
Write a piece of software in one night? Or a piece of software for processing complex vibration data?
This is even more outrageous than publishing a single SCI paper.
"Send it over and you'll see." Lu Feng was too lazy to explain and simply gave his internal network IP address.
"Okay, give it a try." Zhou Mingyuan took it as a joke and opened the local area network transmission tool.
"What I sent you was the raw data just collected from Experiment 3, a total of 450,000 sampling points."
Zhou Mingyuan kept talking as he operated the machine.
"I'm preparing to use traditional empirical mode decomposition to filter out noise from this set of data. Just running this process will probably take this computer at least half an hour."
"bite."
Lu Feng's computer popped up a notification to receive the message.
A .txt file that is nearly 50MB in size.
Lu Feng clicked on "University Data Sauce".
Click "Import Data" and select the file you just received.
A few seconds later, a dense array of data columns appeared in the list box on the left.
Lu Feng selected "Wavelet Denoising" and "Fast Fourier Transform" in the middle algorithm menu.
"Junior brother, your interface style is quite retro." Zhou Mingyuan came over while munching on corn.
Looking at the gray window without even an icon, he became even more convinced that this was just a beginner's toy.
"As long as it can run, that's fine."
Lu Feng gripped the mouse and moved the cursor to the "Run" button at the bottom.
Press the left mouse button.
Zhou Mingyuan took a bite of corn, preparing to see how this rudimentary program would crash.
however.
A green progress bar pops up in the center of the screen.
"Whoosh~"
The progress bar went from zero to full.
The whole process took less than two seconds.
"drop."
A crisp system notification sound.
The blank area on the right was refreshed instantly.
Two extremely clear charts appear side by side.
The above is the time-domain waveform after noise reduction. The red curve is smooth and regular, completely eliminating the glitches in the original data.
Below is the frequency spectrum, with several key resonance peaks pointing upwards, each marked with a precise frequency value.
Below the chart, there is also an automatically generated text report that lists more than a dozen core feature parameters such as root mean square value and peak factor.
The corn in Zhou Mingyuan's mouth fell onto the table.
He was as stiff as a board.
The only sound in the lab was the faint whirring of computer case fans.
A full ten seconds passed.
Zhou Mingyuan suddenly leaned down, his face almost touching the monitor.
He stared intently at the spectrum graph, his eyes wide as saucers.
"This...this peak resonant frequency...1250Hz? And this harmonic?"
He mumbled incoherently, then turned and rushed back to his computer.
My hands flew across the keyboard as I pulled up a set of comparative data that I had spent the entire afternoon yesterday calculating.
He zoomed in on both monitors.
Go through it line by line.
Compare them one parameter at a time.
Lu Feng leaned back in his chair, picked up the water glass on the table, took a sip, and quietly watched him go crazy.
Time passed second by second.
Zhou Mingyuan's breathing became increasingly rapid, and his chest heaved violently.
"All correct."
"The four decimal places are exactly the same."
Lu Feng nodded, not at all surprised by the result.
"The speed is acceptable. It seems that Python is quite efficient when processing data of this scale, as long as the algorithm is optimized properly."
"good?!"
"You call this 'okay'?!"
"When I run this dataset in MATLAB, the preprocessing alone takes twenty minutes!"
"You piece of junk software, two seconds? You get results in two seconds?!"
Zhou Mingyuan's psychological defenses completely collapsed.
He felt that all the books he had read during his two years of graduate studies had gone to waste.
I work from dawn till dusk every day, typing lines of code on the computer and staring at the progress bar like an idiot waiting for the results.
As a result, the makeshift software that someone else wrote in one night finished his day's work in just two seconds.
"How did you do that?" Zhou Mingyuan pointed at the screen, his fingers trembling.
"The underlying system still uses a C-compiled math library. I just put a wrapper around it, rewrote the data retrieval logic, and made use of multithreading."
Lu Feng spoke in a flat tone, as if he were saying that he had eaten two steamed buns that morning.
"We also optimized the base-time decimation algorithm for Fourier transform, reducing unnecessary butterfly operations."
Zhou Mingyuan understood, but also didn't understand at all.
He knew the principle, but to implement it and achieve such an abnormal speed was an even greater feat.
This is something no human being could do.
"Holy crap..."
