Chapter 458 (1/2)

Although the app has only been online for two weeks, in fact, Yang Xiaotian started the layout half a year ago. Hundreds of thousands of microblog fans are not good-looking. Moreover, these microblog fans are sticky and admire Yang Xiaotian's professional level.

So when the health guard goes online, these people are the first batch of users.

At the same time, some of Tong Xin's Weibo fans also provided a lot of help.

This is the same route as when some apps go online and ask stars to speak for them. It's just that Yang Xiaotian really speaks for himself.

Normal is normal, but this achievement is real. 400000 registered users and 50000 deep users. This achievement is very beautiful.

In fact, if an application wants to survive, it must be profitable to ensure that the development and maintenance team and the operation team survive.

It has been estimated that almost 400000 users are needed for an app to survive.

From this point of view, health guards can survive.

Of course, Yang Xiaotian's goal is not so simple.

After a little thought, Yang Xiaotian said: ”good results! Later, you can make a table for each person's workload, and I will give you a bonus! ”

Zheng boning said with a smile, ”OK, I'll thank you for them first! But the bad news still has to be said! ”

”Well, go ahead, I'll listen! I'm mentally prepared! ” Yang Xiaotian joked.

”The bad news is that our app needs a new server, because there are too many users. Now the server is not enough!” Zheng boning said.

”Why?” Yang Xiaotian was stunned. He didn't really know much about computers. After all, he studied medicine, so he asked, ”I remember our server configuration is good, but it's not enough now?”

Zheng boning said with a bitter smile: ”at the beginning, I thought it was enough, but I didn't expect that our app would be so popular. If it was just a general app, our server would be enough, but the key is the particularity of our app!”

Zheng boning began to popularize science to Yang Xiaotian.

General apps, such as watching videos, web pages and games, don't have high requirements for servers. For example, games, mobile phones or computers look colorful on the screen. In fact, they all use the internal resources of the mobile phone to run. They just send some instructions to the server to tell the server what my account has done, Then the server feeds back to the phone.

The requirements for servers and bandwidth are not high.

But health guards are different. To put it bluntly, health guards play with big data.

One of the reasons why it can analyze so many diseases is that there are doctors and experts behind it to interpret some cases artificially.

Second, it has enough case data to find the most suitable case data for analysis according to the user's input.

The second step is actually the core of the health guard, and it not only calls the previous data, but also learns from this data.

It is similar to the recently popular Google Go robot alpha dog.

The core principle of alpha dog is big data, that is to say, many people jokingly say that diligence can make up for incompetence.

How many games of go did Li Shi play?

Alpha dog has played tens of millions of chess games.

But just like this, it's just a more powerful chess score, just like dark blue.

Dark blue is a chess playing computer made by IBM in 1997. It uses big data or exhaustive method.

Before playing chess with people, it only did one thing, learning more than two million matches of all excellent chess players in the past 100 years.

And then in the game.

For example, when people get off the white riding, the soldiers take a step forward.

Dark blue began to calculate. After taking this step, if I go like this, how will the other party go? If I go like that, how will the other party go.

All these calculations are based on the two million games in his mind and the one-to-one analysis of the chess games in the game.

After that, dark blue will analyze it again. If I walk like this and the other side walks like that, how will the other side walk?

In this process, dark blue can calculate the next 12 moves.

This is actually ”calculation”.

Alfa, the dog, added a function of ”learning” on the basis of calculation.

It partly simulates the function of the human brain, using a thread to simulate a brain cell. Tens of millions of threads run on each CPU, which is equivalent to thousands of brain cells on each CPU.

The link between brain cells is also realized by creating new threads, which is equivalent to the neural link between brain cells. The brain cell thread can grow and destroy, and the link thread can automatically change the target of the link. This is similar to the operation mechanism of the human brain.
