Xueba's computing system

Chapter 3 Coincidence?

For OCR character recognition, an outdated AI application field, there have been countless related open source projects since the day AI was proposed.

It can even be said that as long as you know a little about computers and programming, you can find an open source framework to achieve general functions.

However, Ctrl C+V is one thing, and writing it yourself is another.

This is the difference between copying and creating.

The host continued with his kind face, "Does anyone have any questions?"

Soon someone in the audience raised their hand and asked, "Teacher, what are the assessment criteria?"

The host's answer was extremely concise, "Recognition accuracy."

Lin Yuan understood. This was just like a martial arts competition, the assessment criteria were simple and crude: whoever was the last one standing was the winner.

Corresponding to this assessment, the question is who has the highest solution recognition accuracy.

As the saying goes, there is no first in liberal arts and no second in science, the final number representing the result is the only criterion for judgment.

"Do you have any other questions?"

Then the candidates asked a bunch of trivial questions.

“Is it impossible to use open source frameworks at all?”

“What if we borrow their ideas?”

“Are there any requirements for the implementation plan?”

.

.

Lin Yuan found what he heard a little noisy, so he stood up and raised his hand at any time.

His dark complexion due to delivering food quickly attracted attention and a staff member immediately handed him the microphone.

Lin Yuan sorted out his thoughts a little, "Teacher, I have a few questions."

"Classmate, you go ahead."

“First, are there any regulations on the technical solutions used, such as language, IDE, and algorithm?”

The host on the stage nodded calmly, "Yes. No limit."

"That's a fight without rules." Lin Yuan joked.

"Haha, classmate, you are very humorous. But this interview is indeed in the octagon."

Lin Yuan continued to ask, "Second, you just said: open source frameworks cannot be used. Then can open source mathematical tool libraries be used?"

The host pointed at Lin Yuan and nodded in approval. "You asked a good question. This is a good question about interface. Many students asked questions just now, but no one seemed to care about the boundary issue like this student."

Lin Yuan naturally understood the so-called boundary, which was his understanding of the sentence "open source frameworks cannot be used".

“The Math Tool Library is of course allowed.”

In Lin Yuan's view, the mathematical tool library is like the weapons used in martial arts competitions. Not allowing the use of open source frameworks is actually preventing participants from using the famous moves of martial arts masters.

"But..." A kind smile appeared on the host's face again.

"However, many math tool libraries nowadays are more than just tool libraries. Many of them are integrated with integrated solutions. You should be careful when choosing. Don't accidentally call the integrated solution interface." Lin Yuan then said respectfully, "I understand, teacher. I have no questions."

He already knew. This interview was like asking the participants to create their own moves, but they could freely choose their weapons. The so-called mathematical tool library with integrated solutions was like an enchanted weapon. If you were not careful during the competition, you would use the enchanted moves.

Lin Yuan's microphone was quickly passed to another student, who asked his own question, "Teacher, what would happen if the integration solution was accidentally used?"

The host frowned upon hearing this, "Student, why do you ask such a question? Guess why the student just now didn't ask it."

The questioner immediately looked embarrassed, and many people present looked at Lin Yuan, as if trying to read something from his face.

Although the questioner was embarrassed, he did not sit down. "But teacher, how do we grasp this boundary? How do we know which interfaces can be called and which interfaces cannot be called?"

"Oh?" The host looked at the questioner with a caring and kind look, "Student, this is your own problem."

"Okay, Lao Zhang." A man on the rostrum stood up and walked to the host, whispering, "Don't embarrass these children."

Then the man took the microphone and said, "Professor Zhang has made it very clear. Understanding the requirements is the first step to becoming a qualified engineer. This concludes the Q&A on the assessment mechanism."

Lin Yuan also roughly guessed the identity of the host. Judging from the other party's words, it was obviously impossible for him to be a real host. The identity of a professor was more logical.

"The following is a breakdown of the scoring criteria. The actual OCR project results account for 50% of the ranking, and the traditional interview assessment ranking also accounts for 50%. The rankings of the two are added together to take the top 60."

Lin Yuan complained in his heart, it seems that Professor Zhang didn't say the whole story just now, the traditional interview assessment has not been completely abandoned, it's just that its weight has been reduced.

But for Lin Yuan, this is already a good result.

Because he had a certain understanding of the principles of OCR character recognition under the guidance of the computing system, Lin Yuan did not crudely use the heap computing power to create miracles, he tried to read the underlying implementation code of OCR recognition.

However, he didn't understand all the codes.

Lin Yuan called out his system panel. "I was guided to contact the OCR project, and today's assessment happened to be the OCR project. Is this a coincidence?"

Without time to think, more than a hundred people were quickly divided into different classrooms. Each person was assigned a desk, and then they looked at their laptop screens with bitter faces.

A few unlucky guys didn't bring notebooks, so they could only go to the teacher to ask for solutions.

Professor Zhang’s response to this was straightforward.

"Those computer guys who go out without food, you can go back now."

For some reason, Lin Yuan inexplicably developed a favorable impression towards Professor Zhang.
-
In the end, the unlucky few who didn't bring their laptops were not actually sent back, but were provided with machines by the school.

Actually, we can't blame Professor Zhang for his harsh words, because a notebook is like a sword to a swordsman for a computer science student. It is a huge joke for a swordsman to go to the arena without a sword.

Moreover, Lin Yuan clearly remembered that the interview notification email clearly stated "Please bring a laptop to the interview. If this is not possible, please contact the admissions teacher in advance."

The graduate stage is different from the undergraduate stage. Obviously, there won't be many opportunities for you to be lazy.
-
Lin Yuan had previously had an in-depth understanding of the postgraduate entrance examination process for computer science.

I have also heard that during the interview you may need to practice on a computer, or even write code by hand with pen and paper.

But like many people, Lin Yuan did not expect to be asked to implement this type of AI algorithm natively in OCR on the spot.

This can be seen from the situation in the classroom at the moment, because although everyone has a notebook, the sound of typing is sparse. Obviously, many people don't know where to start.

Lin Yuan asked himself, if he had not happened to encounter OCR character recognition, if it was fingerprint recognition, or other image recognition tests, then he would basically be GG.

Even though he has a computing system, this system doesn't have the power to improve it with just one click.
