After the layoffs, I became a tech godfather

Chapter 229 Wearable Neural Products

Three days later.

Wang Rui's surgery went very smoothly; in fact, she was already half-lying on the hospital bed, basking in the early spring sunshine.

She kept gently stroking her abdomen through the gauze with one hand, and she looked exceptionally energetic.

"Mom, I feel hungry!" Although she couldn't eat yet, Wang Rui was excited, her voice filled with joy.

"Good, good, good!" Wang Rui's mother, Zhang Cuiping, was beaming with joy, overwhelmed with excitement.

Before the surgery, no matter how high the success rate was, it was still just a probability. Now, she can finally put her mind at ease.

At this moment, when I heard my daughter say that she felt hungry, I exclaimed "Good!" several times. Heaven rewards those who persevere; it was truly a stroke of luck amidst misfortune.

Unfortunately, she contracted this illness at such a young age, but fortunately, it not only didn't spread, but she also had this opportunity. "Doctor! Doctor!" Zhang Cuiping quickly called for the nurses and doctors, and Zhang Lin also rushed to the ward.

"Is there anything that's bothering you?" Zhang Lin asked.

Wang Rui shook her head: "Everything is fine. I even feel that my entire abdomen is warm and comfortable."

"Hmm." Zhang Lin observed Wang Rui's complexion, which was absolutely perfect.

This is not only due to the success of the surgery, but also largely due to emotions. Such an optimistic and positive attitude, including confidence in the future, is extremely beneficial to recovery.

"That's good!" Zhang Lin said while checking. "Come on, let's look at the monitoring data from the latest EEG cap."

The most common type of brainwave monitoring equipment is the electroencephalogram (EEG), which records the spontaneous, rhythmic electrical activity of brain cell groups using electrodes. Clinically, changes in EEG waveforms can be used to diagnose many diseases.

But it's different now.

The device Wang Rui is wearing on her head right now is the latest "Quantified Self" version of the "Wearable Neural Product" developed by Baiju Technology after acquiring the technology patents of the original Xinbian Technology and absorbing the relevant personnel.

Looking at the raw data, it's still a bunch of signals.

However, after Xiaosha compared and analyzed these signal data, the functions, behaviors, and electrochemical signals of various brain regions became crystal clear.

It would be difficult to perfectly reproduce every word you're thinking right now, but if you combine the current context with an analysis of your tendencies, decisions, preferences, and mood, then it becomes incredibly easy.

And whether the satiety center and hunger center are stimulated is even more obvious.

"Hmm? What, you can understand the raw data too?" Zhang Lin saw one of his students engrossed in studying it and immediately tapped him: "Come on, tell me, what did you figure out?"

Although the raw data contains a great deal of information, it is by no means something that a person can judge with the naked eye without the aid of tools.

It's like a QR code. Although it stores a lot of data, without scanning and decoding it, a person certainly can't get any information.

QR codes only provide two-dimensional information. EEG data, let alone the full amount, even if we only consider the data monitored by the EEG cap, is on a scale that QR codes cannot match.

Even for small sand, a massive amount of computing power is consumed for matching and analysis. Trying to distinguish them with the naked eye is simply wishful thinking.

It's impossible that this Gao Junhao is Zhang Lin's student.

He had been trying to stay to one side, not wanting the teacher to notice him, and even picked up his tablet to pretend to be very serious, but unexpectedly, it backfired.

"I...I...I..." Gao Junhao kept repeating "I...I...I..." for a long time without saying another word.

"What do you mean by 'I' and 'you'? If you don't know, you don't know. If you can't see it, you can't see it. What are you pretending for!" Zhang Lin said seriously, "Don't you understand the importance of being truthful? Look at me, I just say directly, I don't know."

"Hahaha, achoo!"

As soon as Zhang Lin said this, everyone laughed, and even Wang Rui herself was overjoyed.

Zhang Lin continued, "That's what I said during the preoperative seminar. In the past, before performing a treatment or surgery, the doctor himself, especially an experienced doctor, had a certain expectation of the prognosis. In other words, he had a certain idea of ​​what would happen."

"However, things are starting to change now. Even the most experienced person can't do what AI is doing with certainty."

"Why? I've been communicating with Mr. Hao about this issue, and he told me: In just these three days, for the patient Wang Rui, Xiao Sha processed 10 to the power of 9 megabytes, which is PB level, or 1,000 TB level of data."

"If you buy the latest computer now, it'll have a 1TB hard drive, or even two TB, right? That means that in just these two or three days, Xiao Sha can process the equivalent of filling your computer a thousand times over."

"Just this one thing, tell me, as a human being, how do you evaluate what's in it?"

Wang Rui was in good spirits and really enjoyed listening to Zhang Lin's explanations, so Zhang Lin talked for a while longer, and even looked around after he finished.
"Gao Junhao, judging from your expression, you seem to have a different opinion. Come on, tell me." Li Junjie had already shrunk into a quail by this point, but unexpectedly, the teacher still didn't let him off the hook.

“I…” Li Junjie wanted to say that he had no opinion, but it seemed that no matter what he said, he would be criticized. So he gritted his teeth and said, “Teacher, what you just said is wrong.”

"Huh? Something's not right?" Zhang Lin was taken aback. "What's wrong?"

"What TB, PB, that's not what President Hao said, is it? Did he just tell you that the volume is very large and the processing is difficult, and the rest is what you made up?" Li Junjie said.

"Huh? How did you know?" This time it was Zhang Lin's turn to be stunned. Hao Cheng had used a lot of terms and mentioned multiples, but these were the only things he could think of that were related to the amount of data. The data was all calculated by Hao Cheng himself.

How would I know? I visit Baiju Technology's official website eight hundred times a day, and I know all the related actions and updates inside and out.

Although Li Junjie was impulsive, he wasn't without brains. His boldness today was intentional; he was looking to impress. Judging from the current situation, the hospital was definitely going to integrate AI more deeply, especially since his teacher clearly wasn't an expert in that area. The team definitely needed someone to lead it, and this was his chance. He organized his thoughts for a while, and Zhang Lin didn't rush him. Several minutes later, Li Junjie finally spoke:
"Baiju Technology has a collaboration with Huawei." Li Junjie knew that he was no longer answering a question, but conducting an interview, so he raised the bar from the start: "The research topic is: the transmission of the five senses."

"What does that mean? It means using the network, just like the Internet today, to transmit data from a person's five senses."

"Wang Rui's treatment plan utilizes some of the initial results of the research on the transmission of information in the brain through the five senses and five perceptions. Therefore, the difficulty and large amount of data that General Hao mentioned are completely different from the binary concepts of how many megabytes (MB) or gigabytes (GB) of data we usually talk about."

"Although I haven't seen on Baiju Technology's official website yet that it connects the five senses and five perceptions in medicine to the brain and the five senses and five perceptions internet, this direction is easy to guess."

"So, besides the EEG equipment itself, this equipment in our ward is also crucial, right?"

There was indeed a new device in the ward, about the size of a computer case. Its function was to act as a router, receiving the raw signals from the EEG device, encoding them, and then transmitting them.

"I didn't expect you to know so much? Aren't you also in an eight-year bachelor's and master's program? Did you choose computer science as an elective?" As soon as Zhang Lin said this, Li Junjie knew he had made the right bet; the teacher was indeed interested. He quickly replied:

"No, no, medicine is so demanding, how could I possibly have the energy to take an elective? It's just that I am indeed interested in AI, and I think I have some talent for it."

This was no time for modesty. Li Junjie even went so far as to say that Baiju Technology had some talent: "Although I may not be as good as students majoring in artificial intelligence, I can understand all of Baiju Technology's directions."

"Okay! I'll work with President Hao to give you a test. If you pass, you can join the research team."

Li Junjie's little scheme could not possibly escape Zhang Lin's notice, but since he had the intention and the ability, he should be given the opportunity.

"Thank you, teacher!" Although it was just an assessment opportunity, it was still a great opportunity, especially since this project was closely related to Baiju Technology, and Baiju Technology even had more influence than the hospital.

Anything related to Baiju Technology becomes extraordinary.

People in Shandong now have a saying: "If you really can't pass the civil service exam, you can accept working at Baiju Technology as a last resort."

It sounds funny, but it also illustrates a lot of issues. You know, in Shandong, apart from taking the civil service exam, nothing else is considered a respectable profession. This is the first time that Baiju Technology has broken a precedent.

Of course, I was just kidding.

In fact, getting into Baiju Technology is now more difficult than 70% of civil service exam positions.

Of course, besides joining Baiju Technology, people have a second option: to choose Xiaosha's related companies, or the industrial chain and supply chain companies of Class C or Class B cooperative projects. This is much easier now.

Because of the large quantity.

There are already more than 10,000 related companies across the country, especially in Linzhou, where the Linxi New Area, a cutting-edge technology exploration and experimental zone, has nearly 2,000 companies registered or "remotely" registered in the Linzhou High-tech Zone.

The whole country is incredibly envious. These newly established enterprises, not to mention anything else, have brought at least 200,000 high-tech talents, and that number will continue to increase.

With these figures, not to mention other major and medium-sized cities, even Beijing, Shanghai, Guangzhou, and Shenzhen would be envious.

Li Junjie had been paying close attention to the relevant information and connecting Baiju Technology's plans with his own career, hoping that one day he could get on board with this company.

What Li Junjie just said, while still not exactly professional, had already stunned almost everyone present, even the young girl Wang Rui, whose eyes were practically sparkling with admiration.

Wow, there are doctors who understand the principles of AI from Baiju Technology and the five senses network! Although I don't understand much, they just seem so amazing!
So, hard work pays off, and he has already seized half of this opportunity.

As soon as Zhang Lin came out of the ward, he took him to his office and immediately asked a lot of questions: "During the preoperative seminar, we discussed this issue, and many experts said that AI is something we can't control. This has always been a problem."

"They're like, how should I put it, the traditional approach, the doctor needs to be in control of the whole situation, to control everything, they just can't get past this perspective, you understand what I mean? What's your opinion on this?"

What others couldn't figure out, Zhang Lin himself hadn't completely figured out either.

In the case of Wang Rui, the patient, this manifested as a strong desire to delve into the details, trying to understand how the feeling of fullness came about, what substances were produced, what electrochemical signals were transmitted, and how it interacted and communicated with the hypothalamus.

Although he knew that this was something no one person could do alone, he still had a knot in his heart.

I don't understand, what if it fails? The cause is hard to pinpoint.

"Teacher, I can't answer your question. But I can briefly explain the principle behind it to you."

Li Junjie thought for a moment: "Teacher, let me ask you this first. If a patient comes in, you perform a series of tests on him and prescribe a series of medications, and if he has a problem, is there a 100% certain outcome after I take these medications? How would you answer that?"

"One hundred percent? Nobody can guarantee that!" Zhang Lin glared at Li Junjie, who immediately jumped and quickly added, "So, you'll tell him to take it for a few days and then come back for a check-up, right? At least you'll tell him to come back for a check-up if it doesn't work after a few days or doesn't meet expectations!"

"That's right. Even with the same disease and the same medication, each person's physical condition and absorption may be different, so specific adjustments need to be made according to the situation."

“AI is the same,” Li Junjie hurriedly said. “Why was Xiao Sha able to finally determine how the satiety signal was sent? Actually, it wasn’t that he sent it correctly on the first try. He kept trying and then adjusting it based on the EEG feedback.”

"However, it adjusts very frequently. It takes us at least a few days to determine whether a patient is taking medication effectively, but it can check every second and adjust in no time. If there is prior experience, it can even determine a very small accurate range from the beginning, which makes it even faster."

"Therefore, the result is knowable, but the process is undetectable. This is also a characteristic of AI. We can just use it. Compared to so-called experience, AI is much more reliable!"

Li Junjie added at the end, "We can just use it directly. In the programming world, this is called a black box."

……

"Director Zhang!" The two were discussing various issues when the hospital director knocked and entered. "What is the patient's condition? The reporters have been waiting for a whole day and night. Should we hold a press conference to give a detailed explanation?"
