The autobiography I wrote cannot be a tragedy

"Hey! This voice assistant is too smart, isn't it?"

"That is, do you think we have never used Xiaodu Xiaoai elf?"

"It's true, this is definitely an 'artificial' intelligence."

"If you have the guts, call the customer service!"

"Everyone, please understand that for the sake of the show's effect, I just prepared a few questions in advance to heighten the atmosphere. It's not a big deal!"

"The gimmick is gone. The one who went up there must be a dog carrier, right?"

Listening to the discussion below, the reporter in the car rolled his eyes.

Doesn't he know whether he is a dog keeper or not?

Looking at the situation just now, there is almost no delay in the reply. It is hard to imagine the speed that the "human customer service" in the background can compile the answer on the spot and then convert it into a robot voice reply.

It took more than this time to type these words, so it’s not like the other party is a tentacle monster, right?

This "Bajie"...is a bit evil...

While everyone's attention was immediately attracted by "Bajie", the three Xiaopeng's expressions were solemn.

Laymen, your focus is obviously skewed, okay?

price! Price is the key!

"How much did the other party just say? 6.98w?" Xiaopeng looked at his two companions with a constipated look on his face.

"Is it a mistake? Can it be sold at this price? Even if the worst materials are used, the price will be lost to grandma's family, right?"

"The key is the auxiliary driving equipment, which is the bulk of the cost! A lidar alone costs 50,000 to 60,000 yuan!"

The three of them were confused and confused.

If the other party can still make a gross profit at this price, how low will the production cost of the entire vehicle be?

You can’t buy a lidar and give it to your car, right?

"Uh...you think...could the other party be following Tesla's technical route?"

"How is it possible! Even we can't do it!"

As we all know, the current mainstream technical routes for vehicle assisted driving are camera vision, millimeter wave radar, and laser radar.

Among them, lidar has the highest cost, millimeter wave radar is only about one-tenth of lidar, and pure vision has the lowest cost.

Although the future autonomous driving technology must be "multi-sensor collaboration", for now, the simpler the sensor, the lower the cost, and the higher the algorithm and technical requirements. This is an unavoidable fact.

Tesla is based on "no lidar dependence" and emphasizes the optimization of algorithms to achieve advanced assisted intelligent driving by relying only on cameras + millimeter wave radar.

It does not need to know what the obstacle is, it only needs to know that the obstacle exists, and then it can perform the next step!

In terms of technical strength, it is very difficult for vision solutions to achieve L2 (Tesla level) autonomous driving. Many domestic high-tech companies have tried it without success.

For example, Baidu, which was the first to start researching autonomous driving, has been exploring the fusion solution of lidar + vision for many years. It was not until 2017 that it began to explore pure vision technology.

It’s not that pure vision is better than a lidar solution with greater safety redundancy, it’s simply because the cost factor is too high.

Comparing a 2-megapixel camera that costs tens of yuan with a laser radar that costs tens of thousands of yuan each, doesn’t that drive the development of this technology?

The three new forces of Xiaopeng and classmates currently use the entry-level solution of lidar + high-precision map, so the price of the designed model cannot be lower than 15w.

However, with a price of more than 15w, it can only achieve entry-level autonomous driving, and has no competitive advantage in front of traditional fuel vehicles. This is the embarrassing situation that intelligent new energy vehicles currently face.

Technology and cost are the biggest factors for Tesla to rely on the edamame series to make a killing on a global scale!

"Haha! It seems that you have some doubts about the theme of our press conference today. So, let's invite another guest to the stage to experience our 'talking car'!"

At this time, Mr. Bao on the stage, faced with the questioning voices of the crowd, took the initiative to change the guest.

"Come on, come on, Dog Tow No. 2 is about to appear!"

"No matter how many times you replay the play, it won't become real!"

"That's right, I can substitute someone, but I can't let you, Mr. Bao, appoint the person this time!"

"Yeah, who knows if he will be an actor again?"

"Then why not let me do it?"

Everyone looked at the figure in the front row who stood up in surprise.

That was none other than our little classmate!

"Eh? Isn't that Mr. He?"

"Yeah, I didn't expect him to come too. The two people next to him... aren't they the two Mr. Lis!"

Naturally, Mr. Bao had already recognized the three people in the front row. After all, there were only a handful of them on this new energy vehicle track, and everyone basically looked up without looking down.

"Haha! It would be great if Mr. He is willing to be a guest for this experience.

No one should think that Mr. He is colluding with me, right? "

"No, no! We can definitely trust Mr. He!"

Finally, a person whose status was recognized by everyone and who would never be a dog sitter came forward, and reporters and guests naturally supported him.

"Thank you!"

Xiaopeng came on stage, thanked him and took the microphone handed over by the previous "guest".

However, he did not enter the cab immediately. Instead, he walked around the "Saint Bean Shi" twice...

"Two front and rear cameras, integrated ADAS warning and internal and external driving recorders..."

After careful observation, Xiaopeng's face was a little twitchy.

This configuration... is not generally low, but too low...

As a car manufacturer, he is naturally very familiar with the structure of new energy vehicles. He can basically tell everything at a glance.

But... let alone laser radar, there are no traces of the installation of millimeter wave radar.

So how does the other party achieve automatic parking?

It can’t be purely visual, right?

He couldn't help but glance at Mr. Bao, his eyes a little strange.

He didn't say anything at the moment and sat directly in the cab.

"Bajie, what are the processor-related configurations of this car?"

To everyone's expectation, the first question he asked was not to test the voice interactive intelligence at all, but to inquire about the car's configuration.

Many people in the field were confused, but the two companions below nodded repeatedly.

Xiaopeng, this is the key question!

[Hello, this car mainly uses Intel chips as its key computing power support.

Including Intel Atom processor, Intel Movidius vision processor, and Intel ALTAI wireless communication module.

In addition, it is also equipped with Renesas Electronics' MCU control chip and Ericsson's communication module. 】

That's it? !

Xiaopeng glanced at Mr. Bao, his eyes even weirder.

Do you want to engage in assisted driving with this rubbish configuration? Just kidding!

If this can be done, then the opponent will not only use "pure vision", but also need "low computing power"!

The Edamame series needs to be equipped with millimeter wave radar and advanced chips...

This guy...could he really be making false propaganda at the press conference?

There are so many journalist friends!

Do you really think that the country does not arrest entrepreneurs?

"Haha! I didn't know that this kind of low computing power configuration can also complete the assisted driving function. How did you do it?"

[In autonomous driving, ‘automatic parking’ is a low-complexity simple scenario.

In addition, as you said, our computing configuration is not advanced in the market, so we can only complete this scenario at low speed.

This makes up for the hardware shortcomings to a certain extent. 】

"Well……"

Low speed makes up for low computing power, which seems to be logically correct, but it misses the point at all.

"So, this car has achieved 'pure vision' automatic parking technology!"

Xiaopeng emphasized the word "purely visual".

Hearing this, everyone would not understand that Xiaopeng is a drunkard who is not interested in drinking. He is just trying to find out the background of other people's "automatic parking" by experiencing the "talking car"!

[Yes, your understanding is correct! 】

"Wow~" The audience immediately exclaimed.

Unexpectedly, this "intelligent voice assistant" actually admitted it on the spot!

"Ah!"

Considering that this was a live press conference, Xiaopeng did not sneer on the spot, but turned to look at Mr. Bao aside.

"Mr. Bao, do you also agree with the views of your...'intelligent assistant'?"

"Well……"

Mr. Bao touched his nose.

At first, like you, I didn't agree with it, and I even thought the other party was being whimsical.

However, their technology has been stuck on your face, so you can’t deny it...

"Mr. He, I just said that this 'Tianxuan' system is not a product of our company, but a technical support provided by a strategic partner.

So I definitely don’t understand the technical details like you, an expert.

How about... you continue to ask? ” He pointed at the car.

Xiaopeng’s classmate twitched his lips.

What a stupid question!

This is because the boss can’t even edit it anymore, so it can only be done by professionals, right?

good! I want to see what tricks you can come up with!

"This... Bajie, can you tell me how you solve the obstacle detection and tracking algorithm in complex parking environments with low computing power."

[Based on deep learning, combining classic SSD and YOLO algorithms, but with deep optimization. 】

"Huh?" Xiaopeng didn't expect that the other party could give such a professional answer.

"What specific optimizations have you made for SSD?" he asked again in disbelief.

[The main optimization is the convolution part of VGG16, so that it can use the pre-trained VGG16 network weights and perform transfer learning on other data sets to improve the versatility of the model.

After actual measurement, it has a high detection speed and good detection effect in the single-shot object detection task.

The specific optimization process is:

$ L_{Cls}=\\frac{1}{N}\\sum^{N}_{i}L_{Cls,i}$……]

Xiaopeng’s classmate: “…”

Everyone: "..."

Listening to the various mathematical symbols and formulas coming from the car speakers, everyone was stunned.

Hey hey! When asked what optimization you have done, you can just briefly introduce it. There is no need to read out the technical details and optimization formula on the spot, right?

Your company doesn’t have any technical confidentiality regulations?

This operation... Mencius didn't understand it, Confucius didn't understand it, and neither did I.

Many reporters simply felt like shit.

I was just here to write a press release about "The Last Elegy of a Long-established New Energy Car Company". What I didn't expect to attend was an "autonomous driving advanced technology conference"?

There is no psychological preparation at all!

At this time, Xiaopeng’s classmate was thinking about...

Do you want me to get a cheat sheet and copy it down first?

There is no way, the more this algorithm formula sounds, the more it sounds like it is true...

"Stop, stop, stop!" he shouted quickly.

The awkward-to-speak symbol formula broadcast of "Mommy Mommy Boom" finally came to an abrupt end.

"Is it really okay for you to just disclose the technical details?"

This shouldn't be "manual customer service"...manual customer service can't be so arrogant!

[No problem, this technology is technical information that has just been patented and is allowed to be disclosed.

Soon everyone will be able to find the latest technical information on public websites.

In line with the principles of technology sharing and open source progress, developers do not mind opening this patent to everyone! 】

"Well……"

These words...why do they sound familiar?

Like Tesla, playing with public patents?

Many people in the audience were even moved.

However, as an insider, Xiaopeng naturally knows the fishiness involved.

In fact, open patents are not an accurate term. To be precise, all patents are open.

The essence of patents is to exchange disclosure for protection.

For core technologies, companies will not apply for patents to protect them, such as the formula of Coca-Cola...

Tesla is not giving up its patent profit rights, but is temporarily not pursuing infringement liability.

The Iron Man’s original words were: “Tesla will not initiate a patent infringement lawsuit against anyone who wants to use Tesla’s technology in good faith.”

In fact, many car manufacturers will not use these patents directly, but use them to research ideas, because...

The right to interpret "goodwill" belongs to him!

Another more important reason is that in the early days of the popularization of new energy, due to the pressure from traditional car companies, the cost of doing it alone was too high.

So I simply made the patents and standards public, and invited all the big guys to play.

While making the cake bigger together, you can gain huge reputation, and the most important thing is to become the builder of rules.

If you keep imitating, it is impossible to surpass.

The result of mindlessly imitating the forerunners is that you must adhere to the standards set by the forerunners. The further you go, the less likely you are to surpass the other party.

If the benefits of disclosing a patent are greater than not disclosing them, then what reason is there to hide them?

"incredible……"

Looking at the sound wave representing "Bajie" on the car screen, Xiaopeng didn't know what to say for a moment.

Should we be surprised first that the other party seems to have a purely visual automatic parking solution, or should we marvel at the other party's ambition...

but……

After just chatting for a few words, he suddenly found that his attention was diverted again.

Because...this "intelligent voice assistant" is really too smart...

The "self-driving car" is of course shocking, but this "talking car"... seems to be what deserves more attention!

Several times, I forgot to say the awakening keyword "Bajie".

However, the other party seems to be able to actively judge whether he is giving him instructions and respond based on the context...

Compared with double-click wake-up programs such as "Xiaodu Xiaodu", this smoother human-computer communication is simply unheard of!

Judging from the few conversations just now, this artificial intelligence can not only accurately recognize speech and perform in-depth semantic analysis, but also give the most accurate reply in a short time, with an error rate of zero...

What kind of “language model” is this?

Compared with each other, those current in-car smart assistants have to be compared to scum!

He suddenly woke up.

Mr. Bao’s real trump card this time is, as the theme of this press conference says...it’s not “autonomous parking” at all!

Of course everyone in the audience noticed this.

"Hey! It looks like this is really not 'artificial' this time, right?"

"Yes, the response speed and the professionalism of the content don't look like they were prepared in advance at all."

"No way. If there was such a smart voice assistant, those so-called smart speakers would have been eliminated long ago, right?"

"Could it be the same as this car, also the first launch?"

"Which company's product did Mr. Bao say just now?"

"Bai Yeji, I just checked with my eyes, and it turns out it's still a local company."

Xiaopeng ignored the discussion below. He was now eager to know whether the other party was a "dedicated intelligent assistant" specially made for this press conference, or whether it was more versatile...

So, he decided to test the intelligence of this assistant from other angles.

"Your name is Bajie? Why do you have such a weird name? Shouldn't it normally be called 'Xiaodou' or something like that?"

This problem obviously has nothing to do with the car.

[Of course I can’t be called ‘Xiaodou’. It’s like, if someone comes to stay at your house, would you let him have your last name? 】

"Uh...hahaha!"

Everyone reacted for two seconds and burst into laughter.

"This metaphor... is simply perfect!"

"Borrowing? Bai Yeji's products are rented to Idou's car. Doesn't it mean he can't have the last name 'Dou'?"

"Damn it, this voice assistant can't really be a spirit! It can even use metaphors!"

Xiaopeng's classmate was also a little confused by this reply, but he quickly came to his senses.

He doesn't believe that there really is such a capable artificial intelligence in this world!

"Okay, now let's say you are a salesperson, um... just like the journalist friend who just wanted to buy a car but was short of money.

Now let me think of a promotional slogan. What words would you use to promote the sales of this car?

Note that the advertising slogan must be simple and clear, not too lengthy. "

His question was not only long, but also very tricky.

Letting a robot act as a salesperson is equivalent to taking on a role.

It is also necessary to introduce the conversation scene between it and the reporter just now, and refine and condense the final answer...

This will test the robot's memory model and logical language performance.

[Buying a car for my wife! Bought a car for my wife! 】

Unexpectedly, a burst of shouting suddenly came from the stereo.

Everyone reacted for a long time, and the next moment...

"Hahaha! Buying a car for my wife? This operation is 666!"

"It's so appropriate for the occasion!"

"He actually knows a pun. This guy's Chinese proficiency is definitely better than most ordinary people!"

"What do you mean, why don't I understand?"

"That means you are one of those ordinary people..."

"It's incredible! Not only does it answer the question perfectly, but the sales pitch is also deceptive and captures the essence of modern marketing techniques!"

"Let me go...isn't this really the GM answering backstage?"

Yes, there is a big difference between "buying a car as a gift to your wife" and "buying a car as a gift to your wife".

Or how to say that Chinese is broad and profound...

The reporter just now also said it was incredible.

"I bought it! I bought it! Don't try to steal it from me!"

"I want one too, Mr. Bao, are there any discounts for guests on site?"

“I don’t want the discount anymore, I’ll pay in full in cash!”

"And I!"

"I……"

Mr. Bao was a little confused as he looked at the continuous calls for placing orders coming from below.

Holy shit! If I had known that this voice assistant could have such an effect with just one advertising slogan, why would I be recruiting sales?

If "Bajie" is launched another day, can the company's sales department be disbanded?

Only Xiaopeng and his two companions were silent.

Muggle!

This big competitor suddenly appeared, and we were not mentally prepared at all! ,

Regardless of whether this "Shengdou Shi" wants to create a hot spot with this incredible voice assistant or attract attention with its automatic parking, after this press conference, Idou New Energy Vehicles will definitely rely on these two technologies to return to the competitive track. .

They suddenly felt a lot of pressure.

There is edamame in front of this, and idol in the back...

With two bean rivals competing for supremacy, what hope does our new forces have to survive?

Forget about edamame, it is a foreign bean, backed by the strongest technological power.

Unexpectedly, a man who had hidden himself so well would pop up among his own people in the country and stab him and others in the back!

Mr. Bao, boil the beans and burn them in the bean basket. Why rush to fry them?

Originally, they wanted to visit a "Time Metabolism Curtain", but now...

What kind of "temporal metabolism curtain" is here?

This is obviously "The Rise of an Empire"...
