Although the application has only been online for two weeks, in fact, Yang Xiaotian started to lay out half a year ago, and hundreds of thousands of Weibo fans are not good-looking, and these Weibo fans are relatively sticky, and they also admire Yang Xiaotian's professional level.

So as soon as Health Guard was launched, these people were the first users.

At the same time, there are also some Weibo fans of Tong Xin, who also provided a lot of help.

This is the same route as asking celebrities to endorse or something when some apps are launched, but Yang Xiaotian is a veritable endorsement for himself.

Normal is normal, but this result is real, 400,000 registered users, 50,000 in-depth users, this result is very beautiful.

In fact, if an app wants to survive, it must have a profit to ensure the survival of the development and maintenance team and the operation team.

Someone has calculated that there must be almost 400,000 users to keep an app alive.

From this point of view, the health guard can live.

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

After thinking for a while, Yang Xiaotian said: "The results are very good! Go back and make a table of everyone's workload for me, and I will give you a bonus!"

Zheng Boning smiled: "Okay, I'll thank you for them first! But we still have to say bad news!"

"Well, you say, I'll listen! I'm mentally prepared!" Yang Xiaotian quipped.

"The bad news is that our app needs a new server, because there are too many users, and the current server is not enough!" Zheng Boning said.

"Hey?" Yang Xiaotian was stunned, he didn't know much about computers, after all, he studied medicine, so he asked, "I remember that our server configuration is good, right, it's not enough now?"

Zheng Boning smiled bitterly: "At the beginning, I thought it was enough, but I didn't expect our app to be so popular, if it's just an ordinary app, our server is also enough, but the key is the particularity of our app!"

Zheng Boning began to popularize science to Yang Xiaotian.

Like general apps, such as watching videos, web pages, games and other apps, in fact, the requirements for the server are not high, such as games, mobile phones or computer screens look colorful and colorful, in fact, this is to call the phone's own internal resources to operate, just send some instructions to the server, tell the server, what did my account do, and then the server will feedback to the mobile phone.

This is not very demanding on the server, nor is it very demanding on bandwidth.

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

The reason why it is now able to analyze so many diseases is that it has the support of doctors and experts behind it, and some cases are manually interpreted.

The second is that it has enough case data, and will find the most appropriate case data according to the user's input, so as to analyze it.

The second step is actually the core of Health Guard, and it is not just about calling up previous data, but also learning from that data.

It's similar to Google's recently popular Google Go robot Alpha Dog.

The core principle of Alpha Dog is big data, that is, many people jokingly say that Alpha Dog is diligent and can make up for it.

How many games of Go did Lee Sedol play?

Alpha Dog has played tens of millions of chess games.

But that's just it, it's just a relatively powerful game, like dark blue.

Deep Blue is a chess computer made by IBM in '97, and he uses big data or exhaustive methods.

Before playing chess with people, it did only one thing, and learned more than two million games from all the best players for more than 100 years.

Then when playing against people.

For example, when a person dismounts a white horse, the creep takes a step forward.

Deep Blue began to calculate, after taking this step, if I walk like this, what is likely to happen to the other party, and if I walk like that, how is the other party likely to go.

These calculations are analyzed one-on-one based on the chess games in its head of more than two million games.

After that, Deep Blue analyzes it, if I go this way, the other party walks like that, I take another step, how will the other party go?

In this process, Deep Blue can calculate the next 12 moves.

This is actually "counting".

As for the Alpha dog, on the basis of calculation, a "learning" function is added.

It partially simulates the function of the human brain, simulating a brain cell with one thread, and tens of millions of threads running on each CPU, which is equivalent to thousands of brain cells on each CPU.

The link between brain cells is also achieved by creating new threads, which are equivalent to neural links between brain cells. Brain cell threads can grow and die, and link threads can automatically switch to linked targets. It's pretty much the same as how the human brain works.

By inputting learning materials (historical chess games), the connecting threads are automatically linked and converted between the brain cell threads according to a certain algorithm, and the state of the brain cell threads and the connected threads can be stored, which is equivalent to learning knowledge.

Therefore, what Ah Fa Dog stores is not a direct result, but the state of the brain cell thread and the state of the connecting thread. This is very similar to the physiology of the human brain.

There is a stand-alone version and a networked version, and the stand-alone version is limited by the capacity of the CPU, and the number of threads is relatively small, so it is equivalent to a slightly lower IQ.

The networked version can do a lot of brain cell threads and connection threads, which is equivalent to being smarter.

Health Guard, of course, is not as powerful as Google's Alpha Dog, but it is also working in this direction.

This direction is correct, in fact, in the expectation of Yang Xiaotian and Zheng Boning, as long as there are enough in-depth users of the health guard, and communicate with the health guard every day about their physical condition, then the function of the health guard will be more powerful.

It's like a doctor, a doctor who has seen 10,000 patients is better than a doctor who has only seen 10 patients.

The former is well-informed, and it may even be possible for the patient to blurt out what the patient's illness is just by saying what he is feeling unwell.

It's all good.

But the key constraint is that the hardware requirements are relatively high.

The human brain is complex, and the requirements for hardware can be imagined when using a computer to simulate the human brain.

Yang Xiaotian sighed and asked, "The implication is to add hardware?"

Zheng Boning nodded and said, "That's right! Our current server is hosted in the computer room, but I think with the development of our business, because we rely more on the performance of the server, it is best for us to have our own computer room!"

Yang Xiaotian asked, "Need a lot of money?"

Zheng Boning smiled embarrassedly: "Anyway, it's not a small amount! After all, the requirements of the computer room are relatively high, and the broadband has to pull a special line, but we are not making games, and it is okay to have a little delay! The price is not expensive in this regard! The main thing is to have a venue, and the server is piled up, covering a wide area! In addition, it is a decoration, which is also a large expense, the computer room requires dust-free and constant temperature, and because there are more servers, there are also requirements for radiation protection, and then there must be UPS equipment, which is not cheap!"

Yang Xiaotian rubbed his temples, thinking that this was really bad news, he had a headache when he heard it, and he asked, "Okay, you can tell me directly, how much does it cost!"

Zheng Boning said: "After the expansion of the computer room and server, the maintenance personnel must also keep up, and I have a preliminary estimate that at least three million must be invested!"

Yang Xiaotian nodded, and said to Zheng Boning: "I'll call Ye Mengrui in a while, you will take the account from Ye Mengrui when you arrive, what equipment to buy, what venue to rent, you let Ye Mengrui coordinate you!"

"Okay!" Seeing Yang Xiaotian's refreshment, Zheng Boning was very happy.

After hanging up the phone, Yang Xiaotian rubbed his temples, it seemed that the money was made fast and spent faster, if I remember correctly, the total amount of his current savings was only more than 3.2 million, and he went out 3 million at once, it was really ...... Spending money is like water.

And more importantly, the money was not spent by his hands, and he couldn't even hear a sound, which was really unpleasant.

In fact, if he wants to make money, Health Guard can make a profit now.

Zheng Boning said that many pharmaceutical companies have contacted him and want to place advertisements in Health Guard.

For example, if a user of a health guard is not very good at liver function, then the ad he sees is a liver protection drug, and another user has bad cardiovascular and cerebrovascular diseases, and what he sees is a drug that protects blood vessels, which is called precision delivery.

But Yang Xiaotian is not ready to run these advertisements now, mainly because he does not have time to verify the efficacy of these drugs or health products.

Now the users of Health Guard are mainly die-hard fans, and it cannot be said that they overdraft their credibility for money.

It is imperative to do a good job in the service of health guards.

Of course, if you don't sell medicine, you can still do other actions.

The first step is the registration platform.

In fact, there are some registration websites or apps on the market, but Yang Xiaotian wants to compete differently, and the pain point is not that you can register online, but that you can make an appointment.

As a medical professional, he knows that patients have to go to the hospital very early even if they register online.

After all, you still have to queue up at the registration window, then take the registration form, and then queue up at the outpatient clinic.

The main pain point of the health guard is that you don't have to queue up, you can pay directly online and make an appointment to see a doctor.

The imaginary process is as follows: the patient registers with the health guard, makes an appointment, say 10 a.m. to see an internal medicine doctor, and then pays the registration fee.

Then the patient can come to the hospital at 10 a.m., no longer have to go to pick up the number, and directly show the doctor the QR code of successful payment.

And the doctor scans it with a mobile phone or a code scanning gun, and the certification is considered successful.

In this way, to put it mildly, it is to save trouble and time.

If you say it bigger, it will be more meaningful, and there are many aspects that can be expanded, for example, this can be regarded as a materialized office, and it can be regarded as a contribution to the environmental protection of the earth.

……

It's a bit of a Kavin.,It seems that I've been too busy lately.,I don't have time to calm down and think about the reason for the plot.
