Li Feifei, the top Chinese official of Google, left his post: he has to shoulder the responsibility of life and he has to live up to his dreams.


Yesterday, Li Feifei, the top Chinese-level executive of Google’s company, left.

After 615 days as the head of the Google Cloud Artificial Intelligence team, she decided to return to Stanford University to teach and lead the Stanford AI Lab.

Google officially responded, "Li Feifei is an accomplished and respected AI leader."

You may ask, who is Li Feifei?

She became a tenured professor at Stanford University at the age of 36, and served as director of the Stanford Artificial Intelligence Laboratory and Visual Laboratory;

Her high-quality essays have published more than 100 articles in top journals and have been cited for more than 40,000 times;

She participated in two databases: Caltech 101 and ImageNet were widely used by AI researchers, and ImageNet became the world's largest image recognition database;

She is one of the top scientists in academia...

As a Chinese woman, Li Feifei's influence is not only in the academic world.

In 2015, Li Feifei was selected as one of the “Top 100 Thinkers of the World” in 2015 and was named one of the “Outstanding Immigrants of the Year” in the United States (Einstein and Kissinger also won this honor);

In March 2018, won the World Chinese Awards..."

Her name is unknown in the tech world, and it is no exaggeration to say that her research may change the future of the human world.

However, such a Chinese scientist of such excellentness has also been attacked all the way. She once knew nothing about English. She worked as a cleaner, a Chinese restaurant cashier for life, and even helped people to pass the dog. She also borrowed money to open a dry cleaner.

How did she step by step to today? We have combed her growth experience and life experience, hoping to be inspired by you.

1. If you want to do something, then you will find a way.

In 1976, Li Feifei was born in Beijing and grew up in Sichuan. At the age of 16, the family immigrated to the United States. Suddenly entering an environment with completely different language and culture, the biggest obstacle facing Li Feifei and his family is: How to survive?

Although Li Feifei’s parents have all received higher education, they can’t pass English and can’t do good jobs like domestic ones. Due to his livelihood, his father became a camera repairman, and his mother became a supermarket cashier, barely maintaining food and clothing.

In addition to going to school, Li Feifei should also subsidize the family as much as possible, and go to Chinese restaurants and laundry in the spare time to work part-time. Working and going to school have become her whole content for adapting to the new life in the United States. When I am working hard, I can sleep less than 4 hours a day.

But if you want to enter a good university, Li Feifei not only has to master English quickly, but also has an excellent transcript. Only in this way can you get a scholarship from a top university. Otherwise, with their family, they can't afford the high private tuition fees in the United States.

" I want to understand a lot of essential issues, such as the origin of the universe, the meaning of life, etc. I want to have that kind of wisdom in life."

Li Feifei said that this is her driving force.

Of course, she did it.

When she graduated from high school, she was admitted to the computer science department of Princeton University by the world famous university with a score of 1250 on the SAT (American College Entrance Examination), and she received a full scholarship.

This excellent achievement is difficult to achieve even for the locals. For this reason, the local newspaper interviewed her specifically and was famous in the town.

However, at this time, Li Feifei’s family situation is still not ideal.

In order to let her parents make a living in the United States, she borrowed money from friends and even middle school math teachers and bought a dry cleaner. In this way, she is a student at the Physics Department of Princeton University from Monday to Friday; on weekends, she returns to the town to help her manage the laundry business.

A reporter once asked Li Feifei: How have you overcome these difficulties on the road for so many years?

Li Feifei said: " This is my DNA. If I am always sighing, why are there so many difficulties, for me, it is a very distracting thing."

2. It is necessary to take responsibility for life and to be worthy of your own dreams.

In 1999, Li Feifei graduated from Princeton University. As a Chinese immigrant daughter who walked hard with her parents, this is undoubtedly the best time to help the whole family get out of economic difficulties.

At that time, it was a big bull market in the US stock market, and the job market was very good. She was invited to interview several investment banks and consulting companies, and both Goldman Sachs and McKinsey gave her a job offer.

If she went to Wall Street, she would let the whole family live a prosperous life, and it is also a story of "Beijing people in New York".

However, Li Feifei did not choose any job to reduce the family's economic burden. She went to Tibet. There, she spent a year studying Tibetan medicine.

It sounds crazy, and many people can't understand it, but she didn't give up.

For the next full year, Li Feifei stayed in Tibet, overcoming all kinds of difficulties in the cold regions of the plateau, without complaints, quickly integrating into local life medical treatment and conducting Tibetan medicine research. This experience has had a great impact on her.

For a long time, Western scientific methodology and philosophical thinking have occupied the dominant position in the academic world. With Tibetan medicine as the starting point (one), Li Feifei has experienced the completely different side of the entire human thought treasury, for breaking through Western philosophy and science. Methodology is very beneficial. "Tibet doctors have given me a lot of inspiration on the level of philosophy and methodology."

“I value the significance of specific research projects in a larger field. Every study needs to be well thought out before it starts. Although some things seem useless, for example, I am going to study Tibetan medicine, but as long as it is well thought out, If it is accurate, it will definitely work later. Don't worry."

After the return of Tibet, Li Feifei chose to continue to read Bo, which means that she still has only a modest scholarship during this time, and the whole family still has to bear the economic unease.

During his Ph.D., Li Feifei’s mother suffered from cancer and stroke. It was a tough day, and it experienced a lot of difficulties, but in the end it came over.

"The biggest challenge in life is actually to live up to your greatest potential, to live up to your responsibilities, and to face the cause you want to pursue in your own heart." In 2017, she said this in an interview with CNN.

3, the vision depends on the future, to find their own focus, not the most lively point

In fact, after returning from Tibet, Li Feifei also received a large number of consulting companies offer, but Li Feifei still wants to adhere to the dream of benefiting the world with academic research. It is not for money, nor for the environment.

With parent support and his hard work, Li Feifei received a Ph.D. in electrical engineering from the California Institute of Technology, with specific research interests in artificial intelligence and computational neuroscience.

Not only that, she once again made an "astounding" decision when working in colleges - specializing in computer image recognition technology. This was an unpopular study at that time. Unpopular to other professors could not see the results, and felt that they could not get a tenured professorship and would not cooperate with her.

Here, it is necessary to introduce to you briefly - computer image recognition technology. In layman's terms, computer image recognition is to let the computer recognize the content contained in any picture.

For example, let the computer recognize the cat, then first tell the computer that the cat is a round face, a fat body, two pointed ears and a long tail.

However, in real life, there are thousands of cats. Even the same cat may have different postures. At this time, the computer may be dumbfounded.

Faced with such a lack of "vocabulary" in image recognition, Li Feifei began to "train" the computer and let it see more pictures.

Since 2007, she has downloaded nearly 1 billion pictures online, then classified them, tagged them, and built a question bank for computer graphics training. However, due to the heavy workload, the research funding was almost exhausted after a few months, and it took more than ten years to complete the goal of establishing the test bank.

In the most difficult time, Li Feifei even thought about re-running the old industry to open a dry cleaner to raise funds.

When everyone was at a loss, the crowdsourcing platform of Amazon, the largest e-commerce company in the United States, helped a lot. Through the crowdsourcing platform, Li Feifei hired 50,000 people from 167 countries online to screen, sort and tag 1 billion images.

Today, this dataset contains more than 14 million images tagged with everyday English, spanning 21800 categories. It is the famous ImageNet database.

What's more, ImageNet's huge image data is free. It is open to the world, and all teams dedicated to computer vision recognition technology can take “test questions” directly from it to train the accuracy of their own recognition technology.

Today, the computer recognition error rate has dropped from 28% to 3.6%, which is lower than the human eye recognition error rate of 5.1%. This is due to the efforts of the ImageNet database and the Li Feifei team .

In 2009, Li Feifei, who was only 36 years old, won the position of lifelong associate professor at Stanford . Not only the only woman in the Stanford AI Lab, but also the youngest associate professor in the computer department, Li Feifei has been the head of the Stanford Artificial Intelligence Laboratory and Visual Laboratory.

4. The more the industry is, the more people need to be calm and do research.

On December 13, 2017, the Google AI China Center was officially announced. The person who announced the news in Shanghai that day was Li Feifei, a world-renowned AI scholar, Google Cloud artificial intelligence and chief scientist of machine learning.

This is also the first AI research center that Google has set up in Asia.

At the beginning, Li Feifei, who had just entered Google Cloud for less than a week, said in an interview with Xinzhiyuan that she chose to go to Google Cloud. "The reason is that considering the universal value of artificial intelligence, the cloud can correspond to various vertical fields. Such as finance, commerce, health care, manufacturing, agriculture, education, entertainment, media... this is especially important."

Li Feifei said:

"If you want to get involved in industry and industry, what I want to learn most is how to apply artificial intelligence to where you need it, instead of just drawing a cake. "

In the past year and a half of Google's Li Feifei, Google has brought the best Google AI to companies around the world through cloud services, including visual, language, voice and dialogue functions, and built a platform through GPU and TPU. Extend your own model on Google Cloud.

Earlier, Li Feifei also announced on behalf of Google the acquisition of Kaggle, the world's largest data scientist community, bringing together more than 2 million data scientists.

However, for the artificial intelligence that is now "overheated", Li Feifei has also emphasized that "the more the industry is now, the more people need to be calm and do research. Who can calm down, who can go to the end."

She said, "My research experience is that the front of the eye should be relatively empty. If the front of your eyes is lively, then this direction is not the best research direction. The empty places are generally Not a hot spot, so you have to find your own focus."

Li Feifei always believes that if artificial intelligence develops to a certain level, it can fully promote the progress of human society.

Making the human world a better place is the pursuit of Li Feifei. And Li Feifei’s goal has always been the whole world.

5, curiosity and curiosity are important reasons why Li Feifei can go today.

In the 1980s, Li Feifei lived in Chengdu, and Chengdu at that time was far from prosperous today. But her parents especially protect their children's curiosity and curiosity. As long as they have an exhibition, they will take her to broaden their horizons, reach out to the bigger world, and update strange things.

At the same time, there is a very interesting family rule at home: Li Feifei can only do homework within 40 minutes after going home from school. After 40 minutes, he can read extracurricular books, can play, and can do it, but he can no longer do homework.

Parents’ move is to let Li Feifei develop a habit of focusing on high efficiency, doing things without delay, not looking around, and then leaving enough time for himself to do things that he is interested in.

Li Feifei was very curious at a young age. He liked to explore the truth and trace the source of the problem, such as the origin of the universe and the meaning of life. She is eager to have this wisdom, dreaming of benefiting mankind through academic research and transforming the world through technology.

The interest, curiosity, and curiosity that have always been played have played an important role in Li Feifei's future studies, work choices, and research and exploration. This is one of the reasons why she can achieve such an achievement.

Curiosity and curiosity made Li Feifei gradually reach out to a bigger platform, but she did not indulge in glory, but always faced peace. Peace and face others, peace and face life, peace and face science.

At Stanford University, Li Feifei’s class is always full. Some students said that the most memorable sentence to her was always in her class. "The classmates who are late, there are small chairs in the corridor to sit down."

A reporter once asked Li Feifei: What do you hope you can leave for your child?

Li Feifei: I hope that I can do my best to create a better world for my children.

Reporter: What are the things you are doing every day that are helping you achieve this goal?

Li Feifei: "Playing and watching with my children is one of the most important ones. My research field is intelligence. My children have given me too much inspiration about what exactly is smart. Watching children grow up It’s getting more and more smart, it’s a fun thing.”

At 3:53 am on September 11th, Beijing time, Li Feifei wrote such a farewell letter (excerpt) in the WeChat circle of friends:

“The interaction and exchange of ideas between academics and industry has always been an important quintessence of the legend of Silicon Valley.

The road ahead for mankind needs to shine through the lighthouse of thought, which is the unshirkable history of academia and the ideological world at this important historical moment. Responsibility and opportunity. Only people-oriented technology can truly benefit mankind. "

From Chengdu to Princeton, from Stanford to Google, Li Feifei, who has returned to campus again, has been on the road.

Bless Li Feifei!
