Lou Bingcheng looked twenty-seven or eighteen years old, with a Chinese face, thick eyebrows and big eyes, and a pair of narrow-rimmed glasses on the bridge of his nose.

"Hello, Mr. Lin. He smiled and shook hands with Lin Han.

"Hello, Dr. Lou. ”

The two sat down, and Lou Bingcheng said: "Before that, Dong Lei had already told me something about you and your company. He said he admired you and thought your weather plan would be good. ”

He paused: "My main research direction is machine learning and big data, which is really compatible with the computer application of meteorological services, and I have also written some related things independently......

Machine learning is a multidisciplinary discipline that studies how computers simulate the highly intelligent behavior of human "learning".

Machine learning belongs to the core content of the field of modern artificial intelligence, and the "Alpha Dog", which has been popular all over the world not long ago, is based on its basic principle.

"However, as far as I know, the development of meteorological services in China is very lagging behind, and no decent achievements have been made. Does Vientiane have any unique advantages in this regard?"

Lin Han was prepared: "We have three main advantages. ”

"First of all, we have the support of the Provincial Meteorological Bureau, including some of the technology, and all the meteorological monitoring data. ”

Lou Bingcheng hesitated: "With all due respect, general meteorological monitoring data is not very important. The World Meteorological Organization, for example, has a portion of global weather data available for free. ”

Lin Han said with a smile: "In various provinces, the data of the Meteorological Bureau is still very detailed. And the second advantage is that we can get very detailed weather monitoring data through an additional channel. ”

Lou Bingcheng was stunned: "How detailed are the additional channels?"

Lin Han pondered and said, "What is the specific channel, I can't disclose." However, in Handong Province, we can obtain a more detailed meteorological map than the township administrative division map. ”

Lou Bingcheng was shocked: "So detailed!"

Lin Han added: "Of course, in a short period of time, such as a quarter, we can only obtain a few dozen of these detailed weather maps at most, which can be used as ultra-accurate meteorological data to improve the accuracy of forecasting." ”

Such a detailed meteorological map, of course, can only be further refined by him with the help of software on the meteorological map provided by the Provincial Meteorological Bureau.

For example, the local temperature given by the Qinglin County Meteorological Monitoring Station is 25.0 °C, and in his intermediate meteorological authority perception, the temperature in some areas is the same as that of the Qinglin County Meteorological Monitoring Station.

Then he can mark the temperature of these areas as 25.0°C synchronously, and the operation process is similar to "filling" in the drawing software.

In this way, it is equivalent to thousands of additional meteorological monitoring stations, and the level of data detail will inevitably be greatly improved.

Even if he wanted to, the weather map would be detailed to the extent of every square meter and square foot.

But this process needs to be completed by Lin Han himself, each meteorological map means that it needs to be filled in thousands of times, once 1s, there is no desertion at all, and a map also takes at least one or two hours.

For a variety of reasons, it's nice to have two of these ultra-detailed weather maps a day.

It's okay to provide some in the short term, but if it is a long-term stable supply, even if Lin Han's body is iron, he will have to be hollowed out sooner or later.

But he knows in his heart that this kind of ultra-detailed weather map, without too much, can greatly improve the prediction accuracy of relevant software.

Detailed and accurate data is like experience for machine learning, allowing them to grow and mature quickly.

In fact, from the first computer built by Turing, to the structurally mature "Eniac" computer built by von Neumann in the Manhattan Project, to the advent of the first personal computer, the discussion about artificial intelligence has never subsided until today.

Decades ago, it was thought that computers were on the verge of beating the human brain. But to this day, computers are still no match for the human brain in some areas of complex intelligence.

After all, the human brain was developed from the first life on earth after billions of years of evolution, and the birth of the computer is not even a hundred years old, after all, the pattern is ......

However, in recent years, the popularity of artificial intelligence has risen rapidly, so that the popularity of "Alpha Dog" has spread all over the world, and it is so red that it is purple.

The fundamental reason is that the data in the hands of human beings today is far greater than that of decades ago, especially after the birth of the Internet, and the total amount of data in the world has shown an explosive growth trend.

To date, the total amount of data stored in the world has reached 25 zettabytes, which is roughly equivalent to 25 trillion gigabytes.

It is under the catalysis of "big data" that artificial intelligence has become more and more popular.

Lou Bingcheng lifted his narrow-rimmed glasses: "If there is really such detailed meteorological data, then it is indeed a very outstanding advantage." ”

Lin Han continued: "There is a third advantage, we will buy a mainframe computer from IBM for related simulation operations. ”

"Mainframe computers? That's a lot of investment. ”

Lin Han said: "A mainframe is still necessary, and there will be more in the future." ”

Lou Bingcheng thought for a while, and then said: "The advantages of Vientiane are indeed very prominent, frankly speaking...... I'm impressed. ”

Lin Han smiled: "Dr. Lou, I heard that you wrote a very good weather simulator before, can you tell me about it?"

Lou Bingcheng nodded: "That was the idea that I had when I was in junior high school......

Junior high school......

Lin Han then remembered that Dr. Lou received a letter of appointment from Google when he was in high school, but he resigned directly because "learning is important".

Lou Bingcheng continued: "The first code I wrote during the summer vacation after graduating from junior high school, and the code was very rough and not machine learning, but could only be said to be a simple correspondence. ”

"When I was in high school, I taught myself a few assembly language courses and was exposed to some aspects of machine learning. ”

"I had an internship at Microsoft for a while in my sophomore year of high school. Dr. Kipman learned a little about computational graphics, and in his junior year of high school, he watched Jeff. Academician Dean's paper on distributed systems inspired me a lot......"

Lin Han sweated wildly, he didn't even know who Dean was when he was in high school, and everyone talked and laughed directly.

It's not a good feeling at all to watch others pretend to be forced in their own professional field.

"That...... Dr. Lou, tell me about the current situation of the weather simulator. ”

Lou Bingcheng was stunned, and then took out his laptop with a smile: "I'll show you a little." ”
