Counterattack starts with controlling probability

When this question came out, Li Hao was shocked.

Explainability is one of the most difficult problems he faces in this project.

Although he has repeatedly emphasized the decision-making transparency of the model in practice, his theoretical explanation still lacks in-depth and systematic analysis.

He was silent for a moment, then finally spoke, "That's an excellent question. Indeed, model interpretability is crucial in commercial applications. Over the past few months, we've begun incorporating causal inference theory from statistics to present the model's decision-making process to decision makers in a more intuitive way, thereby enhancing their trust in the results."

After Li Hao finished his explanation, the entire banquet hall suddenly became quiet.

An older professor frowned, looking somewhat dissatisfied.

Another young professor spoke up impatiently: "The application scenarios you mentioned seem interesting, but these are just the results of your company's experiments. Can they be applied to other more complex data sets?"

Li Hao's heart tightened, knowing that this was not a simple question.

The methods used in commercial applications are indeed not as rigorously verified and derived as those in academic research.

Although he tried to support his conclusions with mathematical models, the standards in academia are much higher than in the business world.

"Also," another professor suddenly interrupted, "has the algorithm optimization method you mentioned been fully mathematically proven? Is there any academic support? Have you published similar research in academic journals?"

These questions made Li Hao feel pressured.

He knew that these were the demands of academia that he had neglected in the past.

He always thought that he could gain recognition based on his business experience and achievements.

But now he realizes that the academic community does not value these.

Li Hao forced himself to remain calm. "I understand your concerns. We've conducted some experiments within the company and have indeed verified the effectiveness of our method. Furthermore, we've published preliminary research results in several domestic and international journals."

But the older professor remained unmoved: "These are just business practices, which are different from academic research. How can you prove that these methods can be adapted to a broader academic framework, not just limited to your company?"

Li Hao's heart beat faster and the pressure in front of him almost suffocated him.

The academic community seemed to have doubts about his background, which was completely different from business.

He once thought that he could gain recognition through business practice, but he found that the requirements of academia were far more stringent than he had imagined.

Just as the atmosphere was growing heavy, a middle-aged professor stood up and looked at Li Hao with a smile. "Li Hao, your research direction is very promising. 'Business data analysis' has great potential in the future. However, have you ever considered whether, beyond these business applications, you can adapt to a more complex, interdisciplinary research framework?"

Li Hao's gaze froze. The professor's words were gentle, but he clearly sensed a deeper challenge.

The academic community's doubts about his research seem to be more than just superficial issues. It depends on whether he can truly integrate into the academic circle and whether he can cope with broader academic challenges.

Li Hao took a deep breath, trying to calm the turmoil in his heart.

"I understand. This is something I need to continue thinking about." He tried to sound calm, although he was filled with anxiety inside.

At the dinner, everyone seemed to be waiting for Li Hao's response.

There was a tense atmosphere in the air.

Li Hao knew that this was not only an academic challenge, but also a critical moment in his ability to successfully enter the academic world.

His heart surged countless times in just a few seconds, but he quickly calmed down.

He knew that this was more than just an academic debate, and he had to find a solution that would both break the impasse and demonstrate his unique perspective.

He raised his head and looked at the older professor with a determined gaze. "Professor, what you mentioned is crucial—the gap between academic research and practical application. Indeed, business data analysis methods are often limited to practical application scenarios and lack sufficient theoretical support. I admit that my research in this area is still insufficient."

The whole audience was silent, and Li Hao's words directly touched upon the core issue.

He then smiled. "However, I think I can offer a new perspective to fill this gap. We can use the 'cross-validation' method to combine the application models of business data analysis with theoretical frameworks from other fields across disciplines, conducting more extensive experiments and verification."

He spoke slowly but forcefully, his eyes clear and profound. "For example, we can combine theories from finance, psychology, and even sociology, and through big data and machine learning, explore the human behavior and social patterns in business decision-making. This allows these seemingly single business data analysis methods to fit within a broader academic framework."

At this point, Li Hao's tone grew increasingly serious, brimming with confidence. "I believe that if we combine these data models with theories from different disciplines, we can break through the limitations of traditional data analysis and create a more broadly applicable model. This will not only solve business problems, but also contribute new thinking and solutions to the academic community."

He paused and looked at the young professor. "We can verify these theoretical models through real-world case studies, integrating data from various industries. Only by cross-validating across multiple fields can we truly demonstrate the universality of these methods."

The whole audience fell silent again.

Li Hao continued, “I admit that the methods used in business data analysis are not yet rigorous or widespread enough, but through interdisciplinary collaboration and long-term academic research, we can make this field more mature and scientific.”

Li Hao paused for a moment, then added, "I'd like to explore this new direction from an academic perspective, rather than just staying within the commercial framework."

These words directly cut to the heart of the problem and also left a deep impression on the professors present.

He not only demonstrated his respect for the academic community, but also showed his ambition and vision in interdisciplinary fields.

As he finished his speech, the atmosphere suddenly became a little different.

Several professors looked at each other and seemed to start thinking about the plan he proposed.

The young professor's doubts had not completely disappeared, but he began to listen to Li Hao carefully, while the older professor nodded slightly with a hint of approval in his eyes.

"This idea is indeed worthy of further discussion," the young professor said after pondering for a while.

"Well, interdisciplinary research is indeed a good breakthrough." The older professor also agreed.

Li Hao knows that recognition in the academic community is not easy to gain, especially for a "foreigner" like him.

But he never thought of giving up easily. This "cross-validation" proposal is both a response to current challenges and a new vision for the future.

His heart was filled with confidence, as if he saw the other end of the academic path beckoning him.

……

The next day, Noah Technology Headquarters.

Inside the conference room, the atmosphere was as efficient and rigorous as ever.

Li Hao sat in the main seat and glanced at the team members on both sides of the conference table.

Among them are his long-time partners Xu Lei and Chen Kai, as well as new members who joined the company in recent years and quickly became the company's core force, such as Ji Shuqiang.

At this time, everyone was discussing the company's next stage of technology development plan, but there was a rare seriousness in Li Hao's expression.

Halfway through the meeting, Li Hao put down the documents in his hand and cleared his throat: "Everyone, there is something important that I need to tell you in advance."

As soon as the words fell, the conference room suddenly fell silent, and everyone's eyes were focused on Li Hao. Everyone obviously realized that this was not an ordinary work arrangement.

Li Hao smiled slightly, his tone more relaxed. "I plan to study abroad this fall, pursuing a PhD in statistics at the University of California, Berkeley. My application has been approved, and I just received the admission result yesterday."

The conference room was silent, and everyone's expressions gradually changed from surprise to thought.

Xu Lei was the first to speak, frowning slightly. "Li Hao, with your abilities, you are indeed worthy of showing yourself on a higher stage."

Li Hao nodded. "Thank you, Xu Lei. I know this decision may surprise everyone, but it has always been my goal. I hope that through this further study, I can not only improve my academic level, but also bring more innovative thinking and international perspectives to the future of the company."

Chen Kai smiled with a hint of envy. "Brother Hao, I admire your courage in making this decision. I've also been wanting to study abroad for the past few years, but I've always felt that I couldn't let go of my current work. You were able to find time to apply despite being so busy, and successfully get accepted to UCB. It's really amazing."

Li Hao smiled and said, "Chen Kai, you can also consider it. Learning and practice are complementary, not conflicting."

At this moment, Xu Lei revealed a knowing smile: "Li Hao, of course I support you. But I want to ask, are you going abroad with Liu Xia this time?"

The atmosphere in the meeting room suddenly became more relaxed, and several team members couldn't help but exchange meaningful glances.

Li Hao was slightly stunned, then nodded and answered frankly, "Yes, Liu Xia also applied for UCB's MBA program, and her admission result just came out a few days ago. We will go abroad together."

"As expected!" Chen Kai couldn't help but laugh out loud, "Brother Hao, this is called double happiness, right?"

Xu Lei interjected, "That's even better. With Liu Xia by your side, you won't be lonely abroad. Liu Xia's marketing and management skills are a valuable asset to our team. Although she's temporarily leaving the company, I believe she'll reach new heights after returning from her studies abroad."

Li Hao nodded, feeling gratified by Xu Lei's support. "Indeed. Liu Xia's experience and abilities will be crucial to the future development of our team and company. Her successful application for the UCB MBA is inseparable from her years of hard work."

He paused, his tone becoming more serious. "However, I also know that Liu Xia and I's departure will have a certain impact on the company. Therefore, before I leave the country, I will complete the handover of all matters. Xu Lei, Chen Kai, I will discuss this with you one by one to ensure a smooth transition of all aspects of the company's work."

Xu Lei nodded and said, "Don't worry, Li Hao. We will do our best to run the company well and wait for you to return from studying abroad."

Chen Kai also said seriously, "That's right, we will go all out. Boss, just focus on your studies. Learn some advanced skills and come back to lead us in our next sprint."

The other members of the team nodded in support, and the atmosphere struck a delicate balance between lightness and seriousness.

Finally, Li Hao looked at everyone and smiled easily. "This study abroad experience has been a time of personal growth for me, and I hope it will bring more possibilities to the company. In the future, both academically and commercially, I believe our team will achieve even greater success. Thank you for your understanding and support."
