Salted Fish’s Self-help Strategy

"Is this reliable?" Chu Yuanxi asked while looking at it. It doesn't work if you don't ask. Su Gu's printing is too professional for him to understand. This technology claims to use Beidou navigation, without GPS, but in the original world of Chu Yuanxi all use GPS, so I really don’t understand.

Su Gu is a little embarrassed. He didn’t know before “Well, I’ve never used the Beidou system before developing shared bicycles, and I’m not familiar with it. I didn’t expect to find it. Now Beidou is so strong. These days I I spent time studying it, and there should be no problem."

"What's the principle?" Although Chu Yuanxi made the request, she didn't know how to solve it. With the technical characteristics of GPS at the time, the bicycle was blocked by entering the confined space, even under the viaduct or even under the shade of the trees. If it becomes a problem, there must be something new to solve this chronic disease.

The Xiaokang in the original world did not realize that there was still such a problem at the beginning, so there was no requirement for accuracy in the development stage. When the online content was made, it was found that there was no accurate riding data support and it was very passive, so it relied on software. Go round, the foundation is very fragile. Therefore, Chu Yuanxi made the 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 combines the data of the Beidou ground-based enhancement station to correct the satellite signal error."

"Isn't it still the base station plan?" Chu Yuanxi was confused. Before, the bicycle was positioned by the base station when the GPS was unable to count on it, so it was not accurate. How could accurate positioning be achieved by changing the soup without changing the medicine?

"Ah, because Beidou has implemented short messages." Su Gu understands this a little bit, and is better than Chu Yuanxi. While reading the information, he said, "The GPS can only transmit one-way signals from the satellite to the bicycle chip. I know, and Beidou can achieve bidirectional signal transmission between bicycle chips and systems through satellites and ground base stations, which is much more efficient than GPS. When the GPS signal is blocked, the Beidou terminal can communicate urgently through short messages to deal with the complex environment of the city. Very accurate, and the drift area is minimized."

"Fucking domestically produced is awesome!" Chu Yuanxi picked up another propaganda material. It was technically incomprehensible, but the propaganda could still be seen. He found that his cognition of certain things had been fixed in the state before the crossing, and he needed to upgrade now.

And upgrading is urgent. Technology is a light-year away in this era. He broke his head when he was crossing, but he couldn't think of it, and 5g is about to be commercialized. Do you dare to think about it at the beginning of 2018?

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

First of all, in terms of chips, the domestically produced Beidou dual-band soc and third-generation chips were launched last year, making the market quickly commercialized. The sales of compatible chips and modules exceeded 70 million last year, and the price-performance ratio was extremely high. If the bicycle is equipped with this kind of chip with expertise in positioning, it is obvious that the positioning effect will exceed the general chip.

The so-called commercialization means that the hardware is hard enough and the terminal products are rich in variety, which can not only meet the professional needs, but also meet the public. And Beidou is not just chips, even 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 operation and maintenance service providers have emerged to provide industry applications.

This is the background of the emergence of "qx-rtk technology", and it is not only about sharing bicycles. Beidou has begun to explode in other areas of the civilian market, such as automobile networking, smart cities, portable equipment, and various types of application terminals in various industries. Conduct a full strangulation.

And Beidou's next step is to build a global network, push services overseas, and use technology and basic services to eliminate the gps nest!

Chu Yuanxi 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, so far from technology to the market! Then he changed his thoughts, heaven and earth, finally no longer need to use stupid gps!

This is actually a technical ill in Chu Yuanxi's mind that is most likely to hinder the development of Xiaokang's online content. According to the logic of thinking in the original world, it has been smoothed, and he is still preparing to mobilize resources to tackle tough problems. I did not expect that it has basically cured without medicine. 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, Xue Ming suddenly reported another piece of good news. The reason why the popularity of "Out of the World" is worse than that in China, apart from other reasons, the translation of random plots is a big problem. Technically, the level of artificial intelligence translation 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 the two languages. There are insurmountable difficulties, and the other is to improve the quality of the translation ai.

The problem is that translation is a bit cost-effective for Pakistani people to do. The previous access is already the best AI translation kit in China~www.ltnovel.com~ It is not as good as others to let Xue Ming train an AI for translation. It.

So it's nothing.

But in the past February, openai in Silicon Valley released a satellite and released a language-based general-purpose ai. Using language modeling technology, it can edit, translate, and summarize abstracts. The name is gpt-2. The reason is 2, because the first generation of gpt has been introduced long ago, using the same principle, but the performance is average.

This is not the case for the second generation. It greatly expands the training parameter set to an astonishing 1.5 billion parameters, and adjusts the training method of ai to make the goal extremely simple—prediction, summarized by the previous words in the text , Predict the next word and generate an article.

This design idea is extraordinary, the method is not a human learning method at all, but the effect is surprisingly good, because the main idea after the adjustment is "inductive prediction", so you can not conduct 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 do not need to learn the context, they directly use the algorithm to summarize the previous context, and then "predict" the correct words and sentences below. Of course, if it is used as a translation ai, a small output conversion verification model is required, which is slightly more complicated than writing and summarizing.

"You mean, we can use it? Then foreign players can see the original random dialogue?"

"Uh...not yet. I can only use a castrated version with 100 million parameters, but the effect is definitely better than the current one." Xue Ming said embarrassingly, "This time openai is not fully open source."

"Huh? Don't they claim to be fully open source?" Chu Yuanxi was irritated, as if to say how can the free meal not be provided?
