"Yu Bo, Wang Bo, I have admired you for a long time, I have admired you for a long time." Meng Fanqi greeted the two algorithm leaders in turn.

Li Yanhong said that the top management of the institute was mobilized, which is a bit exaggerated, but these two are indeed heavyweights.

Especially Wang Haifeng, who has always been committed to the field of deep learning at Baidu, and later reached the position of the company's chief technology officer (CTO).

At Wen Xinyiyan's press conference, his introduction even slightly pulled back some of Baidu's plummeting stock price. This shows that its technical status is still not low.

"I came here today mainly to demonstrate the effect of the algorithm, right?" Meng Fanqi didn't know Baidu's psychological activities yet, so he just thought he wanted to show the effect and talk about the current interface status.

"I have sorted out the code a little bit, and today I will show you the speed and performance of inference. As for Mr. Li or the two of you if you have any questions, we can just communicate directly on site."

"No problem, our researchers in the detection field have stopped all their work now and are waiting for you." Wang Haifeng said with a smile.

"Ah?" Meng Fanqi was stunned for a moment, and then realized that if his results were true, most of the work of these detection algorithm researchers in the past two years would have been in vain.

This is like currency depreciation. I heard that the U.S. dollars in my hand will soon become Zimbabwe dollars. If I still do such a stupid job, I should just take a rest.

The group of people arrived on the sixth floor and swiped their cards to enter the area of ​​the Deep Learning Research Institute. They saw a group of researchers staring longingly at this place, their eyes almost popping out.

"Let's go to the conference room over there. Let's take a look at the display inside first." Li Yanhong pointed to a completely transparent glass room in the corner and said.

"No problem." Meng Fanqi said as he began to take out his computer from his bag.

This time when I came to Baidu headquarters in advance, it was definitely impossible to show the technical details and code, so I still had to use my own equipment.

Since the contract hasn't been signed yet, of course it's enough to show it to the three senior executives. There's no need to worry about the little soldiers outside.

The three leaders of Baidu are all quick and resolute in their work, and they have no habit of instructing employees and subordinates.

Secretary Liu was left outside. After entering the room, one of the three of them was arranging tables and chairs, and the other was adjusting the monitor. Li Yanhong even personally assisted Meng Fanqi in connecting the device.

This kind of more technical atmosphere with less management atmosphere still feels good to people, much better than Yiqi telling employees to do this and that.

"What I will show you this time is mainly the data results in the last chart. We run the detection data sets commonly used in international papers on site, and run the two versions I provided before on different image resolutions.

Model."

Data tables, after all, are not that reliable. Anyone can write a table and make a PPT today and claim that their detection speed has reached several hundred FPS, and there are major breakthroughs in performance.

The so-called ChatPPT is like this. Prepare some pictures and videos in advance. You can pretend that you have made language intelligence and deceive people into investing.

There is indeed a chance to deceive some wealthy people who do not understand technology. But it is not that easy to deceive the three professional and technical experts in front of you.

"This is a VOC detection data set, right?" Yu Kai once won the VOC competition and is naturally very familiar with this aspect. "Is it 2007 or 2012?"

"I trained the model using the training and verification data from 2007 to 2012. The test set used in the test was the 2007 test set. The data we are showing now is also the 2007 test set. The 2012 test data has not been officially announced.

”

Meng Fanqi answered fluently, which made Yu Kai feel very shaken. It seemed that the other party was at least familiar with detection data.

"Okay, now you run the model and make an inference on about 5,000 pictures of the 2007 test data. Let's take a look at the running speed of your algorithm."

"No problem." Meng Fanqi came to prepare this content today. Naturally, everything is ready. It just needs to be run. "Let's run a lightweight version with a resolution of 320x320 first."

When it was said that there was no problem, Meng Fanqi had already pressed the button and the program began to reason.

The progress bar skyrocketed, and by the time Meng Fanqi finished speaking, it had almost reached 30%.

"What the hell, so fast?" Yu Kai subconsciously said the words on the spot.

5,000 pictures may not be a lot, but if you want to use the current first-class algorithm R-CNN to perform inference, it will take a few hours to complete.

The algorithm run by Meng Fanqi can process more than 200 pictures per second, and it takes more than 20 seconds to complete the reasoning for all pictures.

The difference of a hundred times does not sound that exaggerated, but when you experience it in terms of time, hours and tens of seconds, it feels even more shocking.

"Okay! Okay!" Li Yanhong clapped his palms hard and cheered loudly. "This speed is so impactful!"

Wang Haifeng frowned and thought hard about how he could do this.

Yu Kai and Wang Haifeng are all thinking about the details and principles, but only Li Yanhong has thought about the press conference.

When the time comes, at the press conference, I will put a reasoning video of the world's top detection algorithm on the left side of my PPT, and on the right side, I will put Meng Fanqi's algorithm for reasoning.

It takes a few seconds to process a picture on the left, and the frame is chasing people.

On the right, hundreds of pictures flash by in a dazzling second, enjoying the silky smoothness.

Let’s compare quantities. Given five seconds, the left side may only process one or two pictures, while the right side may process more than a thousand.

Ignore the performance and compare the fastest version with the slower first-class method. Suddenly more than a hundred times turns into a thousand times speed difference.

One picture, densely contrasting a thousand pictures put together. This kind of visual contrast and shock is really exciting!

"I really want to hold a press conference right away!" Li Yanhong's mood rose. He released a technology that is more than a hundred times better than the top level in the industry. This is the greatest pleasure in his life, but it is a pity that there are not many such opportunities.

I have to admit that this quickly completed progress bar gives people a much stronger impact than just a few numbers.

"This is so unscientific!" Wang Haifeng thought for a long time, "This is really unscientific. Can I see the results of your test?"

"No problem, they were all stored in the folder in the directory when I reasoned. You can see that the creation date here is just now." Meng Fanqi clicked on the test results stored under the path and slowly slid them one by one.

The accuracy of each selection box on the picture is very high, and the number of missed and incorrect detections is greatly reduced. Overall, it is much stronger than Baidu's existing algorithm.

Yu Kai and Wang Haifeng looked at each other, and they both read the same thing in each other's eyes.
Chapter completed!
