Chapter Seventy-Nine

"Live demo?" Zhou Qingshan laughed out loud and pouted and said, "Even if I am from the Chinese department, I know that the development cycle of an input method software takes a long time. How long has your company been around? Got a month? Hou Shida, you think you are the protagonist of YY novels, right? I can write the world's first browser program in one night, hahahaha! ”

Hou Shida glanced at him lightly, and his heart was actually very strange. It is said that Emperor Post is also a good university in China, and it is impossible to be admitted to the IQ arrears, but why are there such people in the student union? Mother, cautious, no self-knowledge, on the surface, it seems to be a person, but in fact, it makes people hate it in their hearts.

This week, Qingshan is said to be in good shape, and he can live for at least ten minutes in the TV series. How can a mouth make people feel the urge to be beaten up......

"Oh, President Zhou still knows that he is from the Chinese department?" Hou Shida chuckled, shook his head and said, "Then please shut up, how old are you when it comes to our software majors?" ”

"You ......"

Zhou Qingshan had been robbed like this, and he almost rolled his eyes in anger. However, looking at the eyes of the students around him, they are almost the same contempt.

Hou Shida shook his head in disappointment and said, "What are you?" With your IQ, it's hard for me to explain to you what a beta version is. ”

"Hahahaha-"

There was a burst of laughter around, and everyone also felt that Zhou Qingshan and Hou Shida were really looking for abuse this time, he was a liberal arts student and a professional programmer, and he really didn't know what his head thought.

Zhou Qingshan's face turned pale with anger, and he nodded hatefully: "Okay, then I'll see how you blow the cowhide." ”

Hou Shida turned around, no longer focusing on him, but walked to the wooden frame. He lifted the first page of the wooden shelf, and on the second page was a tree-like diagram, and listened to him.

"Before showing our in-house development beta version, let me briefly talk about the implementation principle of the six-ear input method."

"This is a decision-making tree diagram in which we humans are responsible for linguistic thinking, and I think human language is not only a protocol for transmitting information, but also an important tool for understanding the world. If you want to understand human grammar, you must first understand the two major parts of human thinking - knowledge and intelligence. It can be said that the so-called wisdom of human beings is composed of these two parts. The input method, the way of processing data, has been a two-dimensional tabular database model that is understood by a computer. It is this completely different way of processing data from human thinking that has led to the current data explosion problem. ”

……

Hou Shida kept lifting the white paper on the wooden shelf, and began to talk eloquently from the mode of human thinking.

Don't look at the so-called intelligent input method in the future seems to be blooming everywhere, so I think this thing is very simple. On the contrary, the higher the recognition rate, the higher the technical requirements for the input method. In particular, Hou Shida is not satisfied with the six-ear input method until the whole sentence is entered, but must be able to achieve at least 95% of the first input accuracy under the premise of the whole sentence input.

If you just type pinyin, and then judge the composition of each word, and finally use a few words to form a sentence that doesn't make sense, then you can do it with Microsoft's smart ABC, and the user just taps a few more spaces. But to do the whole sentence input, it is necessary to let the user type the entire sentence at once, in one go. The requirement for data to allow the following words to be automatically associated according to the previous content and semantics is something that traditional phenotypic data cannot provide.

The process of human processing of language is not a two-dimensional structure, but a form of spatial coordinates. In order for computers to realize the "associative" ability of humans, it is necessary to make data have the spatial arrangement of data in the same way that humans process knowledge. To be able to analyze, categorize, and look up data, you need to know how the knowledge in the human mind exists. At the end of the day, it's the electrical impulses in neurons. Neurons, on the other hand, are certainly not two-dimensional structures, but three-dimensional structures made up of all brain cells.

When a neuron is activated, it emits an electrical impulse to all nearby neurons. One neuron does not emit enough electrical impulses to activate another neuron, but if multiple electrical impulses arrive in a single neuron in a unit of time, it will be activated, which is the process of human thought.

Each word entered by the user in the smart input method adds a threshold to the other words that follow. When the threshold of a later word breaks through the critical point, it can enter the range of alternatives. And this alternative database is the key to solving the problem of information explosion. Because it is a database in the form of a three-dimensional matrix, the KNN nearest neighbor algorithm can achieve a very high selection accuracy.

In particular, through this algorithm, machine learning can be realized after several training sessions on new words that have not appeared in the thesaurus. This is especially important for a thesaurus that cannot exhaust human words.

However, none of these Hou Shida students thought that the original data could have a three-dimensional organizational form! For them, this is the opening of a new world!

Not only were the students below dizzy and fascinated by what they heard, but even a few high-achieving students around Zhou Qingshan listened with blazing eyes.

Or it should be said that because they are all top students in school, they have a deeper understanding of these theoretical things that Hou Shida said!

Although Hou Shida really said "generalizations", he did not say much about the application of these principles in software. But all the professional students present can feel in the dark that this knowledge will open a new era!

Even in normal class, no matter how dishonest the students are, they are listening attentively at this time. If there were their professional teachers present, they would have to vomit blood in anger. These little rabbits, in the classes of professors and lecturers, sleep when they should sleep, and whisper when they should whisper, how can they ever be so attentive?

But this is not a large and bright classroom, but a somewhat dim, damp cafeteria, where only one student like them is lecturing, but he listens with relish.

Isn't that weird?

"Okay, that's all for today. Next, please experience the beta version of our six-ear input method. ”

Hou Shida spoke for a long time, turning the white paper on the wooden shelf to the last page. There was nothing on the page, but he walked to the first row of tables in front of him and turned on the projector on the table.

A colorful beam of light hit the paper, and it turned out that this last page was actually used as a projection curtain wall. The projector projects the picture on a blank piece of paper, which is clearly the desktop of a computer, and a rather ugly interface has been opened on the desktop.

"Mr. Hou, can you ask how much your software has been completed so far?" Someone in the cafeteria raised his hand and asked.

"About 55%,We've been speeding up the development process recently.,I believe it will take a few more weeks to complete the development of this input method.。

"The main technical issues have been solved?"

Hou Shida walked to the computer connected to the projector, and said while operating the computer without raising his head: "Yes, 80% of the key technical nodes have been solved, and the biggest work at present is to establish the initial thesaurus." ”

"Since our initial thesaurus is still being revised, the current accuracy rate of the whole sentence is not very high, only about 73%."

"More than 70%, which is a semi-finished product?" This time, even the squad leader Cambrian couldn't help but be moved, of course it was impossible for him to be a squad leader without learning skills. Not to mention the recognition rate of more than 70%, there is not even one on the market that exceeds 50%! With this recognition rate, there is no problem in launching it into the market.

Hou Shida nodded innocently and said with a smile: "Our goal is to make the accuracy of pinyin input reach 95%, otherwise it will not be considered a revolutionary progress." ”

There was a brief silence in the cafeteria with his words, "Revolutionary progress", how many software students dream of this? Students are a bit of a romantic fantasy, and who doesn't want to leave a legend in this world except money? And a revolutionary and progressive software is enough to make a person's name remain in the history of computers.

"Can anyone lend me a book? Any book is fine. ”

"Use mine."

A classmate next to him handed over a book, Hou Shida turned a page with his hand, and tapped the keyboard according to a certain paragraph above without looking at it.

"When he reached the door, the princess stopped him, and Enleko thought that the princess had forgiven him for his crimes, but the princess just said to him: 'Nhleko, you have to pay attention, don't show your man's voice, that's the only place where you will show your horse's feet, don't make a fool of yourself again, if you make a fool of yourself again, your life will be over, so do it yourself!' ”

Hey, what a strange content. Hou Shida looked at this text a little familiar, but he couldn't remember where he had seen it.

However, there are basically no rare words in this text, and the logic of the context is relatively simple, and Hou Shida almost did not make a second choice, and easily typed it out.

The kind of experience that is different from the smart ABC makes everyone present look straight. There's no constant typing of spaces, and no bothering to choose words. As long as Hou Shida's pinyin is typed, a whole sentence will be constantly refreshed under the input box. Even if some of the words in the previous sentence are incorrect, when the whole sentence is entered, the previous mistake has already been corrected.

This feeling of flowing water easily conquered the hearts of everyone present.
