"Is this reliable?" Chu Yuanxi asked while looking at it, no, if he didn't ask, what Su Gu printed was too professional for him to understand. This technology claims to use Beidou navigation, and does not use GPS, but all the well-off people in the Chuyuan Xiyuan world use GPS, so I really don't understand.

Su Gu was a little embarrassed, he was specialized in this, but he didn't know before: "Well, I haven't used the Beidou system to develop shared bicycles before, so I'm not familiar with it." I didn't expect to look for it, and now Beidou is already so strong. I've taken the time to study it in the past few days, and it should be no problem. ”

"What is the principle?" Although Chu Yuanxi made his own request, he didn't know how to solve it, with the technical characteristics of GPS back then, not to mention the bicycle entering the confined space, even under the viaduct or even under the shade of the tree, positioning became a problem, so there must be something new to solve this stubborn disease.

The well-off in the original world, I didn't realize that there was such a problem at the beginning, so the development stage did not put forward any requirements for accuracy, and when the online content was made, it was found that there was no accurate riding data to support it very passively, so it relied on software to circle, and the foundation was very fragile. That's why Chu Yuanxi made a request for the first time this time.

Su Gu picked up a piece of printing paper and said: "The principle is that the positioning chip of the bicycle is combined with the data of the ground-based augmentation station of Beidou to correct the error of the satellite signal. ”

"Isn't that still a base station plan?" Chu Yuanxi was confused, before the bicycle was positioned by the base station when the GPS could not be counted, so it was not accurate, how could the accurate positioning be achieved without changing the soup?

"Ah, because Beidou has already realized short messages. Su Gu knows a little about this aspect, and is stronger than Chu Yuanxi, and said while looking at the information: "Everyone knows that GPS can only be transmitted by satellites to bicycle chips in one direction, and Beidou can realize two-way signal transmission between bicycle chips and systems through satellites and ground base stations, and the efficiency is much higher than that of GPS." When the GPS signal is blocked, the Beidou terminal can communicate urgently through short messages, which is very accurate in dealing with the complex environment of the city, and the drift area is minimized. ”

"the groove domestic is awesome!" Chu Yuanxi picked up another propaganda material, he couldn't understand it technically, but he could still look at the propaganda one. He found that his perception of certain things had been fixed in the state before the time crossing, and now he needed to upgrade urgently.

And the upgrade is urgent, and the technology is a light year away in this era. He couldn't imagine that 5G was about to be commercialized, did you dare to think about it at the beginning of 2018?

In fact, the development of Beidou is far sharper than Chu Yuanxi imagined.

First of all, in terms of chips, the domestic Beidou dual-frequency SOC and the third generation of two chips were launched last year, which made the market quickly commercialized, and the sales of compatible chips and modules exceeded 70 million pieces last year, and the cost performance was extremely high. If the bicycle is equipped with this kind of chip that has expertise in positioning, it is obvious that the positioning effect will exceed that of the general chip.

The so-called commercialization means that the hardware is hard enough and the end products are rich in variety, which can not only meet the needs of professionals, but also face the public. Beidou is not only a chip, but also the sales of domestic high-precision boards and antennas have accounted for a large share of the domestic market. This makes it very easy for solution providers to take shape, and O&M service providers have emerged to provide industry applications.

This is the background of the emergence of "QX-RTK technology", and not only shared bicycles, Beidou has begun to explode in other areas of the civilian market, such as car networking, smart cities, portable devices, and various types of application terminals in various industries are blowing out, and the GPS is comprehensively strangled.

The next step for Beidou is to build a global network, push services overseas, and use the generation difference in technology and basic services to eliminate the GPS nest!

Chu Yuan Xixin said that I have been engaged in self-media for more than half a year, which is equivalent to closing my eyes and opening my eyes, and I have gone so far from technology to the market!

This is actually a technical stubborn disease in Chu Yuanxi's heart that is most likely to hinder the development of Xiaokang's online content, according to the thinking logic in the original world, he is also ready to mobilize resources to tackle the problem, but he didn't expect that it has basically been cured, and the rest of the work is nothing more than Su Gu going to the market to find the most suitable resources for the project.

Unexpectedly, coming out of Su Gu's side, Xue Ming's side suddenly reported another piece of good news. The reason why the popularity of "Out of the Troubled Times" overseas is worse than that in China, in addition to other reasons, the translation of random plots is a big problem, and the level of artificial intelligence translation in technology reduces the player experience.

There are two solutions, one is to train Xue Ming's AI for deep learning with a large number of samples in two Chinese languages, which has insurmountable difficulties, and the other is to improve the quality of translation AI.

The problem is that it is too cost-effective to let the Ba people do the translation, and the previous access is already the best AI translation suite in China, so it is likely that Xue Ming is not as good as others if he trains an AI to translate.

So it didn't work.

But in the past February, Silicon Valley's OpenAI released a satellite and released a language-based general-purpose AI, which uses language modeling technology to compile and summarize summaries, called GPT-2. The reason why it is 2 is because the generation of GPT has been launched a long time ago, using the same principle, but the performance is average.

However, the second-generation project has greatly expanded the set of training parameters, reaching a staggering 1.5 billion parameters, and adjusted the training method of AI, making the goal extremely simple - prediction, induction through the previous words in the text, predicting the next word, and generating articles.

This design idea is extraordinary, and the way is not at all a human way of learning, but the effect is surprisingly good, because the main idea after adjustment is "inductive prediction", so it can be used without any targeted training, and violently sweep all linguistics-related fields.

For example, in translation, the most difficult thing to grasp in translation is the context rather than the grammar and sentence structure, but this set of AI people does not need to learn the context, directly summarizes the previous context through the algorithm, and then "predicts" the correct words and sentences below. Of course, to use it as a translation AI, it also requires a small output conversion verification model, which is slightly more complicated than writing and summarizing.

"You mean, we can use it? And then foreign players will be able to see the original random dialogue?"

"Uh...... Not yet, you can only use a castrated version with 100 million parameters, but the effect is definitely better than the current one. Xue Ming said embarrassedly: "OpenAI is not completely open source this time. ”

"What? Aren't they claiming to be all open source?" Chu Yuanxi was furious, as if to say: How can the free meal be provided inadequately?
