It's very simple, very simple, three days ago, this newly registered newcomer, in a concise and powerful language, slapped an old man in the face, forcing the old man to admit his mistake.

And this old man, who is an engineer in Microsoft Research Asia after real-name authentication, has been well-known in the forum for a long time, and few people dare to refute his remarks, let alone successfully slap his face and force the other party to admit his mistake.

That's one thing, although "K" is a new registered user with no human rights, it also made many onlookers remember this new ID, and they have to admit that this person's level is very powerful.

As the struggle heated up with the many masters on the pinned post, a new post appeared on the page.

New posts are very common, and in this section of the forum, there are not two or three hundred, but one hundred and fifteen new posts sent out in a day, and there are even more replies.

However, due to the fact that too many members are concentrated in the pinned post at the moment, the rest of the posts are lonely, and no one has replied for a long time until this new post appears.

ID：K

Don't look at the title first, I browsed to the ID of the post at a glance, and a few tired senior IDs just came out and refreshed the next page, and I was immediately stunned for a while, and immediately remembered the controversy three days ago.

Then, another thing came to mind.

The main point of contention was natural language understanding.

At that time, the engineer from Microsoft Research Asia answered a request for help, in which he put forward his own insights on natural language understanding in artificial intelligence, which won the praise of many people.

But then the "K" appeared.

No nonsense, concise and powerful, in the most simple words, plain but extremely powerful refutation of the engineer's opinion, and the other party is unable to speak, admitting that his own opinion is inadequate. This scene was extremely impressive to many.

At this time, as soon as I saw the ID of "K" post, someone couldn't help but click on it.

"Test."

The simple two words, or the style of the "K" to speak, do not give you any explanation, just plainly placed in front of you.

Zhao Shiqi is also the person who witnessed that scene three days ago, as a product manager of the mobile Internet, he had two years of study experience in the Cambridge Engineering Department, and has a very in-depth understanding of speech recognition technology, and it is precisely because of this that he admires this mysterious person very much, and admires the other party's deep skills in natural language understanding in speech recognition, which is not the level of ordinary top masters, but the people at the top of the pyramid.

After witnessing that scene at that time, Zhao Shiqi couldn't help the excitement in his heart, and immediately contacted the other party by private message...... It's a pity that so far, he hasn't waited for any reply from the other party.

Zhao Shiqi has no regrets, and it is estimated that the other party does not look down on him very much.

Well, maybe not.

Judging by the mysterious man's style of acting, it is more like indifferent disregard?

It feels very strange, as if walking down the street, surrounded by vendors shouting vigorously for their products, one of the vendors just sits there, neither shouting, nor the kind of laziness that ignores it, but calmly sits on the ground, just placing the goods on the stall, quietly waiting for the destined person.

That's right, this is how "K" makes Zhao Shiqi feel.

It's a bit ridiculous indeed, is there a fate?

Haha, as soon as he thought of his ridiculous idea, Zhao Shiqi felt a little impulsive to laugh...... But his gaze only moved to the bottom of the screen, and he couldn't laugh anymore.

The title is "Test", and as soon as I entered, it was really the question of the test, and I didn't explain what the reason was, nor did I have any explanation or explanation, so I simply put forward a topic below.

"Recommendation algorithms?"

The brow furrowed more and more, and on the dense pages, a wonderfully conceived algorithm was sprinkled on the screen.

"It's kind of interesting."

Browsing down, Zhao Shiqi was really taken aback, the current recommendation algorithm is basically three routines, the first is content-based filtering, the second is social recommendation, and the third is based on collaborationfiltering.

However, the algorithm proposed by this "K" turned out to be a new kind of thinking, and the algorithm that thinks about the problem from another angle is somewhat similar to the latent factor LF algorithm...... But the efficiency seems to be higher, and the algorithm error is much smaller.

Zhao Shiqi wiped the sweat from his forehead, and the staring for more than an hour had already made his neck a little sore and stiff.

took a few deep breaths, picked up the cold tea next to him and drank it all, loosened his shoulders, looked at the blank question at the bottom, and couldn't help but smile a little bitterly.

"Really...... Damn. ”

Even if the topic left behind is so tricky, why can you still attract yourself to it?

What kind of charm exists in these algorithms?

By the way, he was amazed by the core of this algorithm, and he did not expect that he could make such a use of the cosine formula of the angle between two vectors in a multidimensional space, which is completely different from the previous implementation.

"The sword has no intention...... The impermanence of the soft sword...... The epee has no edge...... Wooden sword without lag...... No sword, no move......"

Zhao Shiqi sighed, and somehow suddenly remembered these five realms of Dugu's defeat.

In fact, those who engage in programs and software can also have such five realms.

Those who have just started can only think and do things with the help of the thinking left by their predecessors, and they will only follow the path left by their predecessors to move forward, and this sword is the road and tools opened up by their predecessors.

There are many things in this world that can do this. But if you can use it well, you don't have to worry about food and clothing, and you can be regarded as a senior talent hired by many companies at a high price, and you can also become the pillar of many small and medium-sized companies.

And "soft sword impermanence" focuses on the word "impermanence". When it comes to masters of this level, what they have in common is that they are changeable, no longer make people feel stiff, and they can often make eye-catching characteristics.

This kind of second realm of talents is not only because of their programming strength, but also because they can think outside the scope of their predecessors and look at problems from another angle.

To the "heavy sword without edge", it is a qualitative leap, such talents are all the top leaders of multinational groups, they with their own solid skills, with undoubted strength, dignified crushing, so that you can not speak, impeccable.

And "no stagnation of wooden swords", such people are no longer limited to any blind spots of thinking, they have their own opinions and theories, and can independently create a finished product that surpasses their predecessors, and do it casually, which is the realm that many people cannot afford in their lifetime. Their understanding of software and hardware is no longer something that ordinary people can look up to.

The people of this realm, each named separately, are people who can shake the world, and what they create is the foundation of today's industry, influencing the entire human world. Without them, the lives of human beings today would be inconsistent with what they are now.

As for the last realm, there is no need to say it, in Zhao Shiqi's view, it is not a realm that human beings can reach, after all, no matter how powerful human beings are, they will make mistakes, which is the limitation of the human brain, and it is inevitable.

"Soft sword impermanence? Epee without a blade? ”

Staring at the screen motionlessly, Zhao Shiqi suddenly sighed deeply: "The wooden sword has no lag......"

Maybe it's my own delusion.

Filling in the blank answer, Zhao Shiqi hit the enter key.

"Huh?"

In an hour, the number of replies here reached as many as 500! The number of pages is almost twenty-five!

What's going on? Didn't you quarrel in the top post?

Obviously, so many people were arguing before...... Why are they all gathered here now?

Scrolling the mouse and browsing around, Zhao Shiqi was suddenly speechless, it seems that his solution speed is very fast, no, it should be very good to be able to solve it, there are quite a few people complaining that the question is too difficult, and the input answer shows the error.

In any forum, no matter how many professionals there are, the masters are a minority of the few.

Although he used to think that he was a good master, but at this moment, seeing that many people couldn't solve the answer, Zhao Shiqi was still a little complacent.

It's just that......

"What does that mean?"

Zhao Shiqi let go of his brows that had not been long ago, and once again condensed them tightly together.
