Chapter 19, 19. He picked her up and said, "Jane..."
"So, you want to use an algorithm to summarize Professor Brooke's movement trajectory during the monkey brain surgery?"
Liang Siyu's eyes widened in surprise. Had her algorithmic aesthetics of violence reached this level?
"You must be working a lot, Ada. I don't want you to be too tired." He looked at her tenderly.
“When the professors are training on Fridays, I can request to have the recording recorded so I can compare my own performance with Evan's and see the differences.”
"And I can ask Jessie for advice next week, so I'll just get another scolding this week."
He shrugged. "That's normal. Everyone gets criticized by their advisor."
He was a bit disheartened a couple of days ago, but he figured it out today—if he hadn't really threatened Evan, why would the other party have given him the cold shoulder? He should have more confidence in himself.
Xu Aida shook his head: "It's not just for you. I want people like them to never be able to put on airs with younger students again. The world should be flat, and knowledge should be open to everyone."
The restaurant's soft lighting transformed into a spotlight on a stage, making her the center of attention, breathtakingly beautiful, and mesmerizing him.
The flame burning in her eyes, like the torch of the Statue of Liberty, instantly ignited him, making his heart race and leaving him almost speechless.
He only thought of himself, while she wanted to pierce the walls of selfishness and arrogance, allowing knowledge to flow freely.
When he came to his senses, they were already in front of the computer, with a surgical video on the screen.
Her voice was clear and strong: "Let's start with the smallest product validation."
"Choose segments that are easy to identify, with consistent major movement patterns within the same step, and a clean, unobstructed microscope image. Ideally, Professor Brook should operate only one instrument, as should the assistant."
He paused for a moment, then found a section of the periosteal stripping procedure and pointed it out to her: "How about this part? Professor Brooke used a scalpel, and Evan used electrocautery forceps."
She frowned. The scalpel and electrocautery forceps looked similar in color, material, and length in the video, making them difficult to distinguish.
She asked, "Are there any devices with more obvious differences?"
He dragged the progress bar to another spot: "Here? Wouldn't it be easier to distinguish if Evan used a suction device?"
This is much better; the suction device has a more robust appearance and a matte finish, making it easy to distinguish from a scalpel.
She nodded. "Is this part useful to you?"
He smiled wryly: "Of course, I was criticized by the teacher last week for getting too close while cleaning bone fragments, blocking his operation when I withdrew."
“You just don’t understand his habits yet,” she retorted. “Besides, who told him not to compile a document outlining his operating procedures and send it to his assistant?”
Liang Siyu was amused by her. "Is this what a computer person is like? Such strong document management skills." However, coordinating the rhythm of clinical surgery cannot be solved by a single document.
However, this can also be considered a kind of operational habit document development, his human resources version and her algorithm version.
She told him to first select video clips that met the requirements: "You go first, 10-15 seconds, find at least 10 clips, preferably 30."
“Some complex segments can be extracted first, and the algorithm generalization results can be observed in the next iteration.”
She kicked off the chair and slid it back to her desk, quickly immersing herself in code.
"Damn it, the current IDE (Integrated Development Environment) doesn't support intelligent auto-completion, it's really slowing things down," she muttered to herself.
Two or three hours later, Liang Siyu selected the clip, extracted it, and turned to look at her.
She was furiously typing on the pink keyboard, muttering something to herself, and occasionally rolling her eyes.
A genius algorithm engineer with a volatile sweetheart version, both cute and sexy.
He couldn't help but go over and lean down to put his arm around her shoulder: "Ada, don't stay up so late, okay? I'm not in a hurry."
Without turning her head, she said, "Wait, ten minutes. Let me finish writing this part first, then I'll look at your fragment and consider whether a preprocessing module is needed."
He sighed, but she became focused and wouldn't listen to any advice.
Fifteen minutes later, she turned around: "Where's the clip?"
He sent them to her, and she looked at them one by one. They were alright, not bad. The overall picture was quite clean and clear, with basically no obstructions.
However, there are still low-light areas, so it's best to add preprocessing to avoid misjudgment or loss of tracking.
She started writing new code, thinking that she was more efficient at night. She decided to stay up all night to finish the annotation tool first, and then write part of the algorithm.
Tomorrow during the day, have him manually mark the edges of the equipment, working in a relay fashion to increase speed.
She kept her eyes glued to the screen, not even glancing at him: "You go to sleep, I'll sleep later."
He knew he couldn't persuade her otherwise; the evenings were her comfort zone. He could only advise her not to stay up too late.
"Okay, okay, no problem," she replied casually.
When Liang Siyu woke up the next day, there was no one by his bedside. He jumped up immediately. Had she stayed up all night?
The sound of the keyboard filled the study. She was focused, but her eyes were already bloodshot.
He pulled the swivel chair back immediately: "Ada, you need to rest."
She was so anxious that she slapped his arm back: "Stop messing around, I'm almost done writing this part."
"I'll give you three minutes to save it, then go to sleep." He pushed the chair back, his tone firm.
"Ten minutes, I'll finish in ten minutes. Interrupting my train of thought will waste even more time." She bargained, typing rapidly.
"Okay, ten minutes then."
He went to brush his teeth and heated up a cup of milk before returning. Ten minutes passed, and the adorable algorithm expert showed no sign of finishing.
He pressed his hand on the monitor's power button: "Ada, you're breaking your promise again. If you keep this up, I'll have to manually turn off the screen."
She gently stopped him: "Just one minute, one minute."
Finally, she managed to drag out the time by five minutes and finish writing this part.
She also assigned him the task of making manual annotations—using the annotation tool she had just written the night before.
He shoved the hot milk into her hand, and she pinched her nose and drank it, as if she had just completed a task.
He carried her back to the bedroom, pulled the covers up, and urged, "Go to sleep."
She suddenly blurted out, "Just label it as a 10-frame version, label it every 10 frames, don't be silly and label it as a 30-frame version."
"Okay, go to sleep now." He placed his palm on her forehead, covering most of her face, essentially forcing her to close her eyes.
She instinctively wanted to hide, but exhaustion eventually overcame her stubbornness, and she closed her eyes.
Soon, her breathing became longer and slower, and in her daze, the tip of her nose brushed against his hand.
He made sure she was asleep, carefully pulled the covers up, and then got up to go to the study.
On Thursday night, Xu Aida miraculously finished the first version.
They stayed in the lab, planning to run video analysis during the server's downtime after everyone left at 10 pm.
She first ran a debug version of 10 video clips to check for and identify errors and process them, and then ran a standard version of 30 clips.
After quickly debugging and running the standard version, Xu Aida packaged and output the processed data.
Motion trajectory annotations are overlaid on each original video segment, making key operations immediately clear.
She also used a clustering algorithm to automatically overlay similar operation trajectories, highlighting the commonalities and deviations in action patterns.
Liang Siyu opened the clustering results and immediately noticed that during the periosteal separation stage, Professor Brooke always made the incision from the three or four o'clock position.
He recalled the position of his right hand at that time, which he habitually placed at the three o'clock position according to the rules.
However, this distance is too close for the surgeon, increasing the risk of a collision. He should move up to the two-point direction for better positioning.
Looking at the trajectory of the suction device, whenever Professor Brooke paused slightly, Evan was always able to accurately apply the suction device and maintain the right distance.
Looking back at my own experience that time, I was so nervous that I couldn't keep up in time, and even the suction device was pulled out in the wrong position at the beginning, directly blocking the surgeon's field of view.
He clicked on each original video and carefully examined every trajectory.
Color differences and rhythmic contrasts make the word "stability" no longer abstract.
Professor Brooke's knife tip traced a clear red line, as if drawn by a light pen.
Evan's attractant traces a pale blue path along the edge, sometimes trembling, sometimes veering.
When the movements of the two occasionally overlap, Professor Brooke's trajectory will be momentarily blocked, with some slight pauses and a noticeable decrease in smoothness.
What about him? His self-satisfied performance was merely a preliminary stabilization of his wrist.
If this were recorded and analyzed, he'd definitely be miles behind Evan. No wonder his advisor was so disappointed in him last week.
He was indeed impatient and self-righteous, and from the beginning he did not seriously observe or consider the surgeon's perspective, but only cared about himself.
Xu Aida watched him silently, without saying a word, his expression growing increasingly grim, and asked with some concern, "Ned, is it no use?"
In complex skill domains, early-generation algorithms sometimes provided common-sense information, and perhaps the current version is not good enough.
Liang Siyu picked her up and said, "How could it be useless? It's incredibly useful."
He just thought of another way to use this algorithm system: record his actions, face objective feedback directly, and improve the problem.
She felt relieved and leaned on his shoulder: "It's good that it worked, otherwise it would have been a waste of your two days."
He kissed her forehead: "It's you who has put in so much effort for me, even staying up all night. I don't know how to thank you enough."
She awkwardly leaned forward slightly: "Okay, okay, let's go home."
"The real trouble is yet to come: occlusion and interference, electrocoagulation tweezers identification, multi-case comparison..." A whole host of technical difficulties are still unresolved.
He tightened his grip on her arm: "Don't worry, Ada, you've already helped me so much."
As he spoke, he lowered his head and kissed her deeply.
Those technical questions flew out of her mind.
The laboratory was quiet and still; they shared heartbeats and exchanged body temperatures.
The night was quiet, and this time it was her turn to drive him home.
As she passed the bar downstairs from her apartment building, she suddenly remembered that after he left, she often went there for a couple of drinks on Fridays after working overtime.
However, she has never been drunk. Alone, she wants to get drunk, but dares not.
Remembering that long, lingering kiss, she told herself, "Don't get drunk, Ada, don't get drunk."
Friday afternoon, Professor Brooke's one-on-one training.
They first performed bone window marking and surgical field planning and review, followed by a simulated operation of the periosteal separation procedure, using frozen pig brains for training.
When Liang Siyu made the request to record the video, he frowned slightly, but did not object.
As he stood up, he frowned again: "Did you go to Evan's training on Tuesday?"
Liang Siyu said calmly, "I went. He suggested that I increase my communication with the surgeon during the operation and review the video recordings more often. Do you think my positioning needs to be adjusted?"
He wouldn't complain or accuse directly, but he also wouldn't let others bully him.
Last week he had an emotional breakdown and his reactions were slow; this week, he's just telling the truth.
Professor Brooke raised an eyebrow and quickly replied, "Move it a little to the left."
Compared to Evan, Ned is taller and has longer arms, so he can stand a little further away.
This week, Liang Siyu noticeably increased the frequency of his reports, almost always reporting his intentions in advance for each step.
"Electrocautery tweezers are ready."
"The suction device should be withdrawn immediately at the nine o'clock position."
At first, Professor Brooke was quite patient and would give brief responses.
"We can use tweezers now."
"Don't get the suction device too close, and be careful of the hot freezing point."
However, towards the end, he became a little impatient; he had never encountered such a talkative "assistant."
He said coldly, "Speak less, observe the gestures more, and find your own opportunity."
Liang Siyu knew that she had not yet established that kind of "tacit understanding during the operation".
He could occasionally sense the rhythm, but more often than not, he would miss those subtle signals, fail to keep up, and get criticized a few more times.
However, he was much more at ease than last time. He was rarely scolded for "blocking the field" today, which was a frequently used term last week.
He's been practicing by repeatedly imagining the surgeon's perspective, which almost drove him to the brink of schizophrenia. But now it seems it was all worth it.
Moreover, the use of the attractant is rarely urged.
He's starting to get a feel for that little pause Professor Brooke made in the video feed.
He almost wanted to tell Ada right away that her algorithm was incredibly useful and that she was his lucky charm.
After it was over, Professor Brooke glanced at the video recorder one last time, his eyes deep, and said, "Keep practicing, see you next week," before getting up and leaving.
He was tall and long-legged, and walked with the speed of the wind. But this time, as he passed his secretary Jenna, he suddenly stopped and turned back.
He tapped the table, his tone icy: "Where's Evan? Tell him to come to my office."
