Research starts with PhD students

Chapter 85: Unknowingly, two competitors were eliminated?

Conference Room No. 2.

Zhang Shuo stood on the stage and explained the relationship between the jump equation and computational output.

The signal evaluation system analyzes the signal group, and each signal group will receive a probability evaluation number after passing the evaluation system.

Finally, the energy value is calculated.

The energy value data deviation between signal groups is extremely small, even so small that it can be ignored. When the energy values ​​of a large number of signal groups are superimposed and calculated, the difference will naturally become smaller.

Therefore, the algorithm output is a straight line.

After re-ordering the signal groups according to the probability of evaluating the signal groups by the signal evaluation system, 'interesting' fluctuations may appear in the calculation.

For example, if signals with large values ​​are piled together, the calculation result of an area will be too large and cause the output line to fluctuate upward.

This is an extremely special case of the value of the jumping equation.

"The jump equation is a system of equations, or a system of functions. The following two short equations are adjustments to the parameters."

"Without the influence of special factors, the output will present a three-dimensional straight line."

"On the contrary, there will be jumpy fluctuations."

Zhang Shuo explained very seriously.

He shaped this equation to reduce trouble, because there are too many problems that can be found in calculating the output logic.

Unless you take out the code and explain it one by one, you can always find problems if you want to ask questions.

“If there is any part that you don’t understand, you can substitute the value into the equation and calculate it, and the result will be clear at a glance.”

"The data for each interval can be substituted into numbers to verify..."

"..."

At this time, many people have understood.

What Zhang Shuo meant was that if there were problems related to calculation output, one could find numbers and substitute them into the equations for verification, and he would not have to answer questions specifically.

From a mathematical point of view, this method is effective, but the underlying mathematical logic needs to be improved.

Andreas Hoch asked a key question, "Mr. Zhang Shuo, how do you prove that your equation covers all possible computational outputs?"

In other words, if it does not cover all possible outputs, the equation is invalid.

Zhang Shuo turned and walked to the whiteboard, marking several value ranges on the right side of the equation group.

He explained, "These value ranges cover all possible conventional outputs, including the energy intensity of a single signal group."

"If it is not a normal situation, that is, outside the value range, the output straight line will fluctuate."

"That's what we say, 'All the unconventional possibilities are covered.'"

After he finished speaking, he looked at Andreas and asked, "I don't think I need to prove the continuity of the solution of this equation in the fixed value region, that is, the smoothness problem, right?"

He added, "It's not difficult though..."

Andreas Hawke was stunned for a moment, then shook his head and said, "Of course not, this is not a mathematical argument."

He said and sat down.

This is an algorithm report, not a math report, so it certainly doesn't need to be rigorous enough to prove math problems.

In addition, the jump equation only covers the regular output data range of the algorithm. Ultimately, it is a problem with the algorithm itself. There are many ways to verify it. For example, you can use the code program to perform a large number of calculations to see if there are any anomalies in the regular output data.

That's enough.

After Andreas Hawke sat down, the atmosphere in the conference hall became noisy. Many people had already understood the significance of Zhang Shuo's creation of the system of equations and could not help but start discussing it.

Let’s take the school’s hygiene issue as an example. He installed cameras in every place and covered all areas.

If you have any questions about the hygiene of a place, you can check the surveillance video yourself.

The scholars in the front row were all very surprised and amazed.

They were surprised that Zhang Shuo could create a seemingly strange set of equations for the calculation output.

This is really amazing.

"Did he come up with this equation himself? His math skills are pretty high."

"His mathematical level is already very high. The Annals of Mathematics just published a paper on the boundary extension of the Monge-Ampere equation, and he is the first author. This research breaks the conditional restrictions of natural boundaries that are required for the smoothness of the solution..."

“That’s amazing research!”

"That makes sense."

The scholars involved in the CP destruction experimental research at the scene did not feel very good.

Francisco was rubbing his temple and looking left and right, making eye contact with the others, and they didn't know how to ask the questions.

The question he had just thought of was asked by Andreas Hawke.

All the other questions I had thought of in advance had become meaningless. If I stood up to ask a question, someone would definitely say, "You can refer to the equation and substitute the numerical value to calculate..."

How can I ask this question!

Others felt similarly. Zhang Shuo did not follow common sense at all and created a set of equations for the algorithm output, which they felt was beyond the scope of their field.

On the one hand, the research could not find any problems.

On the other hand, the loopholes in areas where questions can be asked have been filled, for example, the set of equations that shape the calculation output. For another example, at the beginning of the lecture, it was stated that questions related to algorithm logic and framework would no longer be answered.

Thinking about it this way...

The young people on the stage are really mature!
That feeling is not of a young man, but of an experienced old fox...

I want to make things difficult for the other person, but I can’t think of anything to say!
For a moment, there were many discussions in the meeting room, but no one stood up to ask questions.

Andreas Hoch exchanged a few words with the other judges, and finally stood up and announced, "OK."

"Mr. Zhang Shuo, Mr. Agostini, and Mr. Kalvach, after discussion, we have decided to include your research papers."

Agostini and Kalvacher stood up together.

Andreas Hoch continued, "But this does not mean that the meeting agrees with your calculations."

"This algorithm is too complicated, and we cannot verify whether it is correct. I can only speak for myself and think that your research is correct."

Kalvaher stood up and said, “After the meeting, we will make all the programs public, including the core algorithms and other program modules.”

He told everyone, “Anyone can view the source code. Anyone who disagrees with the research can find errors in the code.”

Many people applauded after hearing this.

For any algorithm-related research, making the source code public can be said to be a great thing.

Even unrelated people can learn a lot from the source code, and some fields may use the programs in the source code.

Those scholars involved in CP experimental research were not very happy.

If the source code is not open, they can still firmly say that there is a problem with the algorithm. After all, algorithm programs have bugs, and a small line of program will affect the final output results.

No matter how perfect the algorithm logic is, the resulting program may not be perfect, and the results calculated by the program may not be correct.

The source code is public, so it doesn't make sense to say that.

Anyone who has a problem can check the source code and find the problem in the source code. If they can't find it, how can they say there is a problem?
Zhang Shuo walked off the stage.

Agostini and Kalvaher also followed.

The scholars in the front row stood up and congratulated them on the approval of their research.

Anne-Lullier shook hands with Zhang Shuo and said, "You are really young and promising. You are in your 20s, right?"

"25 is old."

"very impressive."

Anne-Lullier exclaimed, "Your research is great, but the impact is a bit too great, and many people may be unhappy."

She was referring to the people who were doing research on baryon CP destruction.

Zhang Shuo said, "Science is about progress through constant revision."

"We have proved that the signal conversion method of hyperon decay cannot find baryon CP violation, which indeed makes many experiments and research meaningless, but at the same time, it also points out another direction."

As he spoke, everyone else fell silent.

Zhang Shuo looked around and continued, "We found abnormal fluctuations in the experimental data analysis. There are some unknown influences in the area where the fluctuations are located. It may be a baryon cp signal or other influencing factors."

"Any institution or individual can use our code to examine hyperon decay data to find out which regions are more likely to find CP violation signals."

“If we can improve the technology and enable the experiment to provide more detailed signal data, I believe we will be one step closer to a research breakthrough…”

The people around applauded after hearing this.

Science advances through correction. Finding the right direction and improving technology will bring us one step closer to completing the research.

However, some people feel completely differently.

Greyward was in no mood to think about the future. He and his team had no future at all, and any new direction had nothing to do with him.

Given the situation at Fermilab, I will definitely be laid off when I return, and most of the team members will also be laid off.

I have lost my job, what is the meaning of the future?
Francisco was not in the mood to think about the future. If the CP group found a new direction, it would be equivalent to changing the project, and the person in charge would definitely be changed.

He would not lose his job, but it would be impossible for him to continue to be the head of the CP group.

Tan Zhiming's situation is the best, as he does not have to worry about work problems, but it is still difficult for him to accept the denial of his past research.

After hearing Zhang Shuo's speech, he felt like he saw hope again in despair.

He turned his head to look at Francisco, then glanced from a distance at Grayward who was slumped in the chair.

Seems to be……

Without realizing it, two competitors were eliminated?
"If we change direction when we return, won't we be able to attract a large number of talents in related fields to join us?"

"This research started from scratch, and every step forward will lead to achievements..."

He couldn't wait to go back.
