Hardcore crisis

It's very simple, very simple. Three days ago, this newly registered person severely slapped an old man in the face with concise and powerful words, forcing the old man to admit his mistake.

As for this old man, he is an engineer at Microsoft Research Asia after real-name authentication. He has been well-known in the forum for a long time. Few people dare to refute his remarks, let alone succeed in slapping him in the face and forcing the other party to admit their mistakes. .

Just like this, even though "K" was a newly registered user with no human rights, many onlookers at the time remembered this new ID, and even more recognized that this person was very capable.

Many experts were arguing in the pinned post. When the fight became more intense, a new post appeared silently on the page.

New posts are very common. In this section of the forum, there are not only 200 to 300 but 150 new posts a day, and even more replies.

However, because too many members were concentrated in the pinned post at the moment, the rest of the posts were deserted, and no one responded for a long time until this new post appeared.

ID:K

Ignoring the title, I glanced at the ID of the post. A few senior IDs who were tired of the noise just came out and refreshed the page. I was stunned for a while and immediately remembered the debate three days ago.

Then, another thing came to mind.

The focus of that debate is about natural language understanding.

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

But this "K" appeared immediately.

No nonsense, concise and powerful, using the simplest words, he refuted the engineer's opinions in a plain but extremely powerful way, leaving the other party speechless and admitting that his own opinions had shortcomings. This scene left a deep impression on many people.

At this time, as soon as they saw a post posted by "K"'s ID, someone couldn't help but click in.

"test."

These two simple words are still spoken in the same way that "K" spoke, without giving you any explanation, just placed in front of you plainly.

Zhao Shiqi was also the one who witnessed that scene three days ago. As a product manager for mobile Internet, he had two years of study experience in the Cambridge Engineering Department and had a deep understanding of speech recognition technology. This is why he has a deep understanding of speech recognition technology. This mysterious man was very impressed by his profound skills in natural language understanding in speech recognition. He was not at the level of an ordinary top expert, but someone at the top of the pyramid.

After witnessing that scene, Zhao Shiqi couldn't help but feel excited, and immediately contacted the other party via private message... Unfortunately, he has not received any reply from the other party until now.

Zhao Shiqi is not without regrets, and it is estimated that the other party does not think highly of him.

Well, maybe not.

Judging from the behavior of this mysterious man, it seems more like indifferent disregard?

This feeling is very strange, just like walking on the street, when the vendors around are shouting about their products, one of the vendors is just sitting there, neither shouting, nor being indifferent and lazy. Instead, he sat calmly on the ground, placed the products on the stall, and quietly waited for the right person.

Yes, this is the feeling "K" brings to Zhao Shiqi.

It's indeed a bit ridiculous, a destined person?

Haha, Zhao Shiqi had the urge to laugh when he thought of such a ridiculous idea... But his eyes only moved to the bottom of the screen, and he couldn't laugh anymore.

The title is "Test", and as soon as you enter it, it is really a test question. There is no explanation of the reason, nor any explanation or explanation, just simply put a question below.

"Recommendation algorithm?"

His brows furrowed more and more, and on the densely packed page, a wonderfully conceived algorithm appeared on the screen.

"interesting."

As he continued browsing, Zhao Shiqi was really surprised. The current recommendation algorithm basically has three routines. The first is content-based recommendation (content-based filtering), the second is social recommendation (socialrmendation), and the third is based on Collaborative filtering recommendation (collaborationfiltering).

But the algorithm proposed by "K" turned out to be a brand-new way of thinking. The algorithm that thinks about the problem from another perspective 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. Staring for more than an hour had already made his neck a little sore and stiff.

After taking a few deep breaths, I picked up the cold tea next to me and drank it all in one gulp. I relaxed my shoulders and looked at the blank question at the bottom, and couldn't help but smile a little bitterly.

"It's... abominable."

Even if the remaining questions are so tricky, why can they still attract me to get involved?

What kind of charm exists in these algorithmic formulas?

By the way, he was amazed by the core of this algorithm. He didn't expect that the cosine formula of the angle between two vectors in a multi-dimensional space could be used in this way, which was completely different from the previous implementation.

"The sharp sword has no intention...the soft sword is impermanent...the heavy sword has no edge...the wooden sword has no stagnation...no sword has no moves..."

Zhao Shiqi sighed, and somehow suddenly remembered these five realms of Dugu Qiubai.

In fact, those who engage in programming and software can also have these 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 can only move forward by following the path left by their predecessors. This sharp sword is the path and tool opened up by the predecessors.

There are many people in the world who can do this. But if you can use it well, you will have no worries about food and clothing. You can be regarded as a high-level talent hired by many companies at a high price, and can also become the backbone of many small and medium-sized companies.

And "soft sword impermanence" focuses on the word "impermanence". What masters at this level have in common is that they are versatile and no longer feel rigid, and can often create eye-catching features.

Such talents in the second realm lie not only in how strong their programming skills are, but also in their ability to jump out of the thinking scope of their predecessors and look at problems from another perspective.

When it comes to "heavy sword without edge", it is a qualitative leap. Such talents are all top leaders of multinational groups. With their incomparable solid skills and unquestionable strength, they can crush you openly and let you Nothing can be said, impeccable.

As for "Wooden Sword Wu Zhi", such people are no longer limited to any blind spots in thinking. They have their own opinions and theories, and can independently create products that surpass their predecessors. Just doing it casually will make many people happy in their lifetime. An unattainable realm. Their understanding of software and hardware is no longer something that ordinary people can look up to.

People of this level, each name taken individually, are people who can shock the world. What they create is the foundation of today's industry and affects the entire human world. Without them, human life today would be inconsistent with what it is now.

As for the last realm, there is no need to talk about it. In Zhao Shiqi's point of view, it is not a realm that humans can achieve. After all, no matter how powerful humans are, they will make mistakes. This is the limitation of the human brain and is inevitable.

"A soft sword is impermanent? A heavy sword has no edge?"

Staring at the screen motionlessly, Zhao Shiqi suddenly sighed deeply: "Wooden Sword Wu Zha..."

Maybe it's my own misunderstanding.

After filling in the blank answers, Zhao Shiqi hit the Enter key.

"Huh?"

Surprisingly, within an hour, the number of replies here reached 500! The page count is nearly twenty-five!

What's going on? Don't you want to make a quarrel in the pinned post?

It was obvious that so many people were so noisy before... Why are they all gathered here now?

After scrolling around with the mouse, Zhao Shiqi was suddenly speechless. It seemed that he was solving the problems very quickly. No, it would be great if he could solve them. There were actually quite a few people complaining that the questions were too difficult and the input answers showed errors. .

In any forum, no matter how many professionals there are, the experts are still a minority among the minority.

Although he thought he was a good master before, now that many people can't figure out the answer, Zhao Shiqi is still a little proud.

only……

"What does it mean?"

Zhao Shiqi relaxed his brows for a short time and pressed them tightly together again.
