"If we continue like this, it would be more cost-effective for us to manually traverse the customized strategy."

Hearing his words, Chen Nian also frowned.

He asked:

"Can you see why?"

"I can't tell. I feel that there should be no big problem with our algorithm, but cold start consumes too many resources."

"The essence of machine learning is also traversal, but it cannot make any reference to perceptual experience."

"In other words, artificial priors and machine priors are not aligned."

Looking at Wang Jiancheng's slightly disappointed eyes, Chen Nian continued to ask:

"What about the confusion matrix we talked about last time? Can it be solved?"

"It cannot be solved. Our problem now is that we have relatively few priorities and experience. If we want to obtain high-level solutions efficiently, we must require the machine to have an extremely high level of intelligence."

"And currently, the generalization of this task, that is, the difficulty of generalizing the task itself, is very difficult, which further increases the requirements for the machine."

"No, running away like this is not a problem."

With that said, Wang Jiancheng directly hit the stop button and the model stopped running. The final result was that in more than 60,000 training sessions, effective results were achieved only twice.

This amount of data is simply not enough to support the continued training of the model.

Wang Jiancheng looked at the results on the screen with disappointment. At this moment, he felt an indescribable sense of frustration.

In fact, at the beginning, he was extremely confident in this model.

After receiving Chen Nian's advice and gradually understanding the basic principles of the convolutional neural network algorithm, he almost felt that the whole world was in his hands.

The potential of this set of algorithms is really great. As long as we continue to develop it, it is not an extravagant hope to one day completely change the world.

Moreover, on this track, I am already countless steps ahead of other researchers. As long as I can produce usable results and cases, I will most likely become one of the pioneers of the new generation of artificial intelligence together with my seniors.

This is such a great honor, no need to elaborate.

With such self-confidence, he could be said to be making great progress all the way, so fast that Chen Nian was amazed.

He originally thought that things would develop smoothly like this, but he did not expect that the results of the first training of the model gave him a heavy blow.

It’s not just that the results don’t meet expectations, it’s that it’s not usable!

If it fails to meet expectations, you can move closer to the goal through continuous adjustments and optimizations, but if it doesn't work, then it's really useless no matter what you try.

Starting over may be the only way.

But can I still have such a spirit?

Chu Jianshu listened silently to the conversation between the two. In fact, this result was within his expectation.

You know, this is artificial intelligence!

Even in science fiction, the vision for artificial intelligence is decades away.

In this era, if you want to achieve primary artificial intelligence under the current computer computing power, you also have to consider the performance upper limit of the terminal. How easy is it?

Being able to achieve this step is already a success in a certain sense.

The next road still needs to be walked slowly step by step.

——

Of course, when it comes to solutions, he actually doesn't have them.

Before, because of his interest in the project, he had also learned some knowledge about machine learning and convolutional neural networks.

According to the discussion just discussed by Chen Nian and Wang Jiancheng, the biggest shortcoming of the entire model is the lack of priori. If a large enough sample database can be implanted in the model and the machine can perform deduction and learning according to the samples in the database, then the machine training

The difficulty should be reduced exponentially.

Such a strategy is not easy for others, but it is not difficult for him.

If you want data, it's just a matter of a few phone calls.

For its own scientific research purposes, wouldn’t it be enough to ask the military to send over some training records of pilots? If not, just let them fly a few times according to the target logic.

But the problem is that this method of solving the problem is tantamount to undermining the success of the two children.

This time, I can help them solve the problem through my privileges, but what about next time?

If this is an urgent scientific research task, no matter what means are used, Chu Jianshu will not think it is excessive.

But now, it's more of an exploration.

Talents need to be cultivated. In the process of leveling up, you can give them some help and point the way, but you can never help them defeat the boss.

Thinking of this, Chu Jianshu asked calmly:

"Then what are you going to do now?"

The two were silent for a moment, and then Wang Jiancheng spoke:

"There are two ways to go."

"Or, I'll find a way to contact the aircraft model club and ask them to brush up the prior data for us."

"But the accuracy of the data produced in this way is relatively poor. I don't know how much time it will take for secondary processing."

"It's very possible that by the time the data is processed, the time to apply for the special class will have been missed. But as long as the model can be written out, it won't be a loss."

"There is another way, which is to tear down the entire model and start over."

"I just thought about it carefully and found that there are actually many overlooked efficiency optimization points in the model. Once these points are solved one by one, there will definitely be benefits."

"The problem is that if we do it this way, the underlying logic will also need to be modified, and the amount of work will be relatively large."

Wang Jiancheng sighed helplessly, raised his head and looked at the ceiling.

"At least it's better than having no choice. If there's a problem, you have to find a way to solve it. We'll think about it when we get back."

Chen Nian nodded slightly and said nothing.

In fact, what Chu Jianshu can do, he can also do.

But his original intention of joining this project made him unwilling to use this somewhat "opportunistic" method.

This is a bit embarrassing.

However, besides this method, is there no other way?

He always felt that he seemed to have overlooked something. What exactly was it?

On the other side, Chu Jianshu nodded happily after hearing Wang Jiancheng's answer.

Fortunately, my first reaction was not to give up, nor to subconsciously seek help from myself, but to plan a solution.

This shows that, at least in terms of character, they have basically passed the test.

So, he patted Chen Nian beside him on the shoulder comfortingly and said:

"It doesn't matter, that's what scientific research is like. Sometimes it takes hundreds or even thousands of failures before you can succeed once."

"Take your time, you still have time."

"Understood, Professor Chu. Don't worry, these are all minor problems. Let's talk to the teachers from the School of Mathematics tomorrow to see if we can do some optimization on the algorithm."

"That's good if you have this idea! Come on, let's go have a late-night snack? I'll treat you to it!"

After hearing his words, Chen Nian smiled slightly and stood up calmly, not forgetting to remind Wang Jiancheng to return the initial settings of the minicomputer.

After cleaning up, the three of them walked out of the school gate and had a bite of food together. During the process, both Wang Jiancheng and Chen Nian were a little silent.

Of course Chen Nian was thinking about the fleeting flash of inspiration that flashed through his mind just now. As for Wang Jiancheng, he was most likely thinking about the model.

Seeing the performance of the two people, Chu Jianshu didn't say much.

He was still thinking that maybe the two children were shocked and didn't want to talk. Of course, they might be planning the next step, but no matter what, he shouldn't disturb them too much.

Things that need to be experienced will always have to be experienced. Since you have made up your mind not to interfere, you must follow through to the end.

However, when he returned to his residence, he still couldn't help but feel a little worried.

Many geniuses actually died in one or several failures.

Especially for young geniuses - because their minds are not yet mature at this time, a small setback may cause a huge butterfly effect, and ultimately cause irreversible effects.

Is Wang Jiancheng such a person? Is Chen Nian such a person?

Chu Jianshu hoped that they were not, but he was not too sure.

——

However, such worries only lasted less than two hours.

Just after he finished washing, his personal mobile phone received a call from Wang Jiancheng.

On the other end of the phone, Wang Jiancheng said excitedly:

"Professor Chu, we want to borrow a minicomputer tonight! We know how to do it!"

"What? How?"
