Our guest today
is amazing.
I could memorize “Three Hundred Tang Poems.”
You know
the nicknames of all the 108 heroes
in “Water Margin.”
I could even memorize
the constellations of the 108 heroes.
The “Prince of Folk Songs”
just stands
beside Mr. Sa.
We had to withdraw although we wanted to recover the Central Plains.
Good.
He’s Mei Hong,
an academician of CAS and
the Vice President of BIT.
From a young man who loved culture and arts
to the leader in the big data field,
he’s witnessed the development of informatization in China.
I searched
ladders online.
Before long,
the ads of different ladders popped up.
I even got
some ads of lifts.
That’s why
some pushes are stupid.
What is big data?
Big data means
a large amount of data.
It’s wrong.
Online shopping,
navigation
and finding and killing Osama Bin Laden
are based on big data.
What’s the use of big data?
Can big data analyze stock accurately?
Can I get rich
by learning big data?
Big data
is the new engine
for economic transformation and growth.
What will our life
look like in 2020?
Realize a well-off society in an all-round way.
This is the special series of “Voice,”
“Foresight in 2020.”
Win the college entrance examination and boost the future.
Hello, dear audience.
This is “Voice,”
China’s first TV show offering open lectures to the young
exclusively sponsored by Yingding Education,
the advocate of intelligent education
in college entrance examination.
I’m your host, Sa Beining.
Welcome.
Extract plant essence
to scientifically supplement both qi and blood.
Thanks to Yunnan Baiyao Qixuekang Liquid
that is a good choice for staying up
for the great support to the program.
It’s the first time
in five years
that we have changed
a new stage background.
Do you like it?
Yes.
The new stage
carries the new content.
We’ve specially designed
a new series,
“Foresight in 2020”.
What will our life
look like in 2020?
To what extent
will our country and nation
develop by 2020?
All this depends on
every step
we take today.
Our guest today
is amazing.
He
beats his peers
hollow
at literature.
He can even recite
“Three Hundred Tang Poems” backwards fluently.
Moreover, he peruses kung fu novels
and knows well the master-apprentice relationships
in different schools.
Allegedly, he’s thoroughly
familiar with “Water Margin”
and knows well
the nicknames and features of
the 108 heroes.
Don’t get me wrong.
Our guest isn’t
engaged in literature.
Instead, he’s
a pure and pute science geek.
He studies
big data.
Big data
permeates
in our life.
For example,
I searched household ladder
online some time ago.
Before long,
the ads of
different ladders
popped up
when I watched the news
on the website.
Maybe it was because of
big data.
Our guest today
can dispel my doubts.
Why did
the ads of different ladders
pop up before me for a long time?
Let’s applaud to welcome our guest,
Mr. Mei Hong,
an academician of CAS
and the Vice President of BIT.
Welcome.
Hello, Mr. Mei.
Hello.
Welcome.
Hello, Beining.
Please.
Thank you all.
Please be seated.
Mr. Mei,
it’s said that you know
the nicknames of all the 108 heroes.
I’ve forgotten almost all of it.
Wu Song?
Pilgrim.
Song Jiang?
Protector of Justice.
He has several nicknames.
Timely Rain.
What kind of tiger
does Wu Song slay on Jingyang Ridge?
It should be South China Tiger.
Why?
The northeast wasn’t included
in the territory of the Song Dynasty.
It’s the association of another data.
Well,
I could even memorize
the constellations of the 108 heroes
when I was a middle school student.
I was interested in it.
How about their blood types?
The novel doesn’t record it.
I was willing to memorize these things.
I could memorize “Three Hundred Tang Poems.”
I still liked it in college.
I ran a poets’ club
and a literary club.
When I gave a lecture one day,
I suddenly changed my thought.
I majored in computing.
I didn’t need to memorize
many things.
My cranial capacity is limited.
I can’t memorize so many things.
So I didn’t
memorize things gradually.
I focused on
abstract logical ability.
If I think the computer
can help me do something,
I’ll give it up.
I won’t do it.
I just gave an example.
I searched ladders online,
and then my phone
was glutted with the ads of adders.
Is it a reflection of
the application of big data?
The technical term
is programmed data trading.
Behind it
is the push mode
formed by computer programs
after data interconnection and sharing.
It’s fully automatic.
Yeah.
It’s not artificial.
That’s why
some pushes are stupid.
Something that we don’t want is also pushed.
Right.
I even got some ads of lifts.
Yeah.
What’s
the problem?
When you browse a website,
do you agree to
push your data?
Theoretically,
shopping is your privacy data,
but to conveniently
shop online,
you have to
upload your data.
It’s like news push today.
After we read some news
on military affairs…
Yes.
…or
a certain event of sports,
we’ll find that
there seems nothing else in the world.
It’s all about sports.
The same kind of thing is pushed.
It’s an intuitive feeling
brought by
the application of big data today.
It’s convenient,
but now
the intelligent
push technology
has a lot to learn.
Big data
is an interesting concept.
I dare say that
many people don’t
understand big data accurately.
What exactly is accurate big data?
What is the status of big data
in China now
and its future development strategy?
Mr. Mei will tell us
all this today.
Next,
I’ll leave the stage to Mr. Mei.
Let’s give Mr. Mei a big hand.
Thank you, Beining.
It’s a great honor to be here.
It’s a new stage.
This is the first episode of
“Foresight in 2020.”
I’d like to
begin with a figure.
A figure
will occur in 2020.
What’s it?
44ZB.
It’s a term
to describe
computing speed
and storage capacity.
B means
byte.
What does ZB mean?
The 21st power of 10.
I’ll draw an analogy,
and you can do the math.
We listen to songs every day.
A 3-minute song
will take 10M
if it’s recorded in Mp3.
If the memory space is Z,
how long does it take to listen to all songs?
More than 800 million years.
It’s a prediction
in 2020
given by IDC.
Let’s look back.
What was the global
data volume in 2003?
5 million T.
What’s T?
The 12th power of 10.
1,000,000,000,000.
What was the volume in 2009?
0.8Z,
less than 1Z.
The volume in 2020 will be 44Z,
but it was 0.8Z in 2009.
How much will it be
by 2030?
2,500Z.
This is an era
in which data grow rapidly.
Think about it.
Data have been
playing a very important role
in the development of
human society.
At the beginning of civilization,
people kept records by tying knots.
It’s one of the ways of recording data.
After words were invented,
writings were for conveying truth.
It’s also a way.
Modern scientific data modeling
directly uses data.
It’s also a way.
I remember around 2014,
“Xinwen Lianbo” on CCTV
began to use the word big data,
like the big data of Spring Festival travel rush
and NPC and CPPCC.
Back then,
the viewers of “Xinwen Lianbo”
got to know this new word
in life.
However, many people
have misunderstandings.
For example, for many people,
big data means a large amount of data.
It’s wrong.
What’s the essence of big data?
The depth of data mining
and the width of application,
namely the breadth of cross-border integration.
It’s what big data means.
I’ll cite the example of
the U.S. census in 1996.
The number of births
in the U.S. census was 4.9 million.
This figure is
an objective data description,
but if we associate it
with the data 40 years ago,
we’ll find that
from the 1950s to the early 1960s,
there was a baby boom
after World War II in the U.S.
It’s called postwar baby boom.
Many babies were born back then.
The association
gives us a message.
What’s it?
After the postwar baby boom,
the golden age of fertility
for this group of people has gone.
Let’s look back again.
In the U.S.,
in the 10 years after 1996,
or in the 1st decade of the early 21st century,
how many junior high school teachers retired?
How many junior high school students graduated?
Moreover,
at that time,
tax cuts were needed to curb salary growth,
so politicians
were under pressure
not to let teachers’ salaries
rise too fast.
If we put these things together,
we’ll come to a conclusion.
In the first decade of the 21st century,
the U.S. might
face great educational pressure.
It was the pressure
of baby boom on education.
What did it mean?
They might have to
make new government decisions,
and there might be new business opportunities.
This is the tremendous progress
we have made in human development
through data acquisition,
analysis and application.
What does big data bring for us?
Each of us is surrounded by
big data.
When we shop online,
after we place
the orders,
the owner of the site
will gather all kinds of data together
and get a huge data pool.
Then
he can
analyze many things,
such as our credit
and shopping habits.
The map navigation
we use
every day
is the traffic-related data
from all walks of life.
It can tell us where traffic jams are.
The gathering of these data
brings much convenience
to our life.
There are many applications of big data.
There are many international examples.
I’ll tell you
a cool example.
Palantir is a company in the U.S.
It’s a company engaged in data analysis.
One of its most proud efforts
was to
help the U.S. government
find and kill Osama Bin Laden.
How did it get the data?
It collected the data
that governments could provide,
like his financial data,
communication data
and social network,
to form an entity relationship network
and help intelligence officers
analyze where Osama Bin Laden was.
There are many other successful examples in 2016.
AlphaGo defeated Li Shishi.
Now we can’t defeat it
in Go anymore.
The success rate of AI
to predict the Academy Awards
was nearly 88%.
These are some things
that we feel directly.
What can big data
bring to the country
and social development?
It provides us
with a new means or new thinking
to understand the real world
and complex systems.
Big data is the new engine
for economic transformation and growth.
It’s called digital economy.
What’s digital economy?
It’s a new economic form
after agricultural economy and industrial economy.
What the digital economy bears
is different from
the development of the past decades.
Information technology was used
more as tools and means
in various industries to help them improve quality
and increase efficiency in the past decades.
In the digital economy era,
information technology will become a leader.
That is to say, data are the key factors of production.
Network is the most important carrier,
and the application of information technology
is the most important pusher.
That’s one of the connotations of digital economy.
It’s said that many jobs
will be replaced by robots in the future.
What’s behind this?
The application of information technology
based on big data.
Think about it.
In the past,
a country had sovereignty over
its land, sea and air.
Later it was extended to aerospace.
Land, sea, air and aerospace.
What’s the new territory
constructed online?
Cyberspace.
I wonder
if you know the Snowden Incident
which happened several years ago.
Snowden was an employee of a defense contractor.
He disclosed the PRISM Program in the U.S.
The core of the PRISM Program was to
make a comprehensive analysis of
all kinds of information
that could be collected on the Internet
and get intelligence for the U.S. security services.
Can you protect your cyberspace?
In this sense, big data is a new tool
to enhance the comprehensive capacity of the country
and to safeguard national security.
If a country
has no such capacity,
how can it protect its safety
and enhance its ability
in the international competition in the future?
Big data is also a new way
for government administration or social governance.
There are many examples
to share with you.
I wonder if you
apply for a provident fund loan.
How many processes are needed?
First, you have to go to
the Provident Fund Department
for the authorization of the credit enquiry
and go to the bank for the credit report.
Then your company proves your salary,
the Civil Affairs Department certifies your marital status,
and other departments certify your other statuses.
You have to
go to over 10 departments
before you can get the loan.
Later,
all service departments
gather in
the government affair hall,
so we don’t need to go around the city.
But we still have to queue up
window by window.
Every window we have to
hand in the ID card,
the copy of ID card and other materials.
We do the same things
and fill in the data repeatedly.
Now Zhejiang is carrying out “one stop, one trip, one paper”.
It takes Quzhou as a comprehensive pilot unit
to launch “one window acceptance”.
The applicant
takes his ID card,
purchase contract
and down payment voucher
and will get the loan
in half an hour.
Quzhou made a statistic.
It (full-year provident fund business)
can generally reduce by 180,000 times of
handling affairs and 120,000 times
of proofs issuing, amazing ability,
which brings stronger
senses of gain and happiness.
This is the example of big data
we are talking about.
What does the era of big data
bring to us?
It brings convenience to our lives,
and raises
our work efficiency dramatically.
I have fortunately experienced
these stages of information development.
I still remember
when I first started learning computer,
60 students in two classes
shared only one machine.
That machine was called DJS-130 Computer.
It was a product
produced by China.
It was as big as
a cabinet air conditioner.
The whole class used it.
It had no operating system.
I’ll tell you
how simple it was only.
How much memory did it have?
4K.
That was the first computer I came across.
Later, I graduated and studied for my master degree.
My instructor arranged me
to develop a software for a factory.
Many steel parts
were cut by the cutter in the factory.
With a large steel plate,
I placed all kinds of parts
on the steel plate
to save material and the steel plate
as much as possible
while considering
the traveling path of the flame cutting machine.
Right?
When it burned the steel soft
and it needed to change its path.
So this is a multidimensional optimization problem.
Then I developed a software
called Layout Software.
I was very lucky at that time.
I was specially assigned with a PC.
I could use it for 24 hours.
How much was a PC at that time?
Tens of thousands of yuan.
So I really
witnessed the massive use
of PCs in China
at that stage.
Informatization of every unit in China
also began at the time.
That was first wave of informatization,
beginning with the massive use of PCs.
What is the second wave?
In the mid-to-late 1990s,
with the commercial use of the internet,
we entered a new phase,
the networking phase featuring in
networked application.
Early before,
when we saved money at banks,
we would have handwritten coupons.
Later, each bank
completed the single informatization work
and the internet era began to concentrate.
And we could save and withdraw the deposit
in different branches of the same bank.
Now we can do this across banks
through the same network.
Remittance can be done in this way.
This is the second wave.
And through over 20 years
of accumulation to the present,
we have accumulated a lot of data
as what I described just now.
Which phase are we in now?
A new intelligent phase
featuring in in-depth excavation,
fusion and application
of data.
What will the future look like?
In my own imagination,
a major social change
in human history
is kicking off.
For the young present,
it’s exactly the era
you are facing.
Are you ready?
To survive in the future society,
besides knowing how to use tools,
you have to have
an important change
in a lot of thinking ways.
No matter you are learning computer
or other majors,
this is a basic ability.
In the current era of big data,
I think we must have
a few kinds of thinking:
computational thinking
and big data thinking.
In the current society,
do you still need to do brain calculation
and mental arithmetic
or recite the multiplication table?
You can finish mathematical calculations
with your cell phone
at any time.
So when you encounter
a complicated problem
in your real life,
you may think of
whether it can be solved
by computing.
That’s to model the real problem
with some concepts of computational science
to solve it in the computational way.
This is the computational thinking.
What is data thinking?
You have to learn how to get
and analyze the data,
how to extract value from the data
and how to apply the data.
You need to have such a thinking way
and such a change
to be better riders
in the era
when the informational big data
bring us opportunities
and challenges.
China is embarking on
a new journey of becoming a power.
Then how can we improve our technological strength,
especially the information technology strength
in the new era?
In early days, we basically
had little contact with the international.
Until the 1990s,
we always did our own things
within China.
We did a lot
to fill the gaps in China.
After 2000,
a group of scholars went international.
We began to
have a good presentation,
accumulate good influence
and gain a lot of results
internationally,
becoming leaders.
But, in general, we should notice that,
the overall level of technology,
especially the level of information technology,
is still far behind developed countries.
So whether we can complete innovation
of own independent technology
in the implementation of
National Big Data Strategy
and acceleration of
the digital economy development
within a long time in the future
has not been our responsibility
but the responsibility of the young present.
I hope that,
you can realize the dream
of enhancing our country with technology
through innovation and efforts
no matter what industry
you are engaged in.
Prospering technology will proper nation.
Strong technology can strengthen the country.
It’s also my hope for everyone.
Thank you, Mr. Mei.
Thank you.
Extract plant essence
to scientifically supplement both qi and blood.
Yunnan Baiyao Qixuekang Liquid
that is a good choice for staying up
invites you to stay tuned in “Voice.”
Thank you all.
Please take a seat.
In your speech, you talked about
a lot of big data in China.
I think many young people
can’t deeply feel
the development
of the computer technology
from the beginning to the present,
not to mention
the big data.
Because for them,
everything around them
seems to be normal
and already long-lasting
since they were born.
But this is not true.
They are created by
generation after generation of scientists
adhering to such a spirit.
In the course of your speech,
many audiences on site
wrote you small notes.
Next, let’s move on to
the small note interaction part
sponsored by Yingding Education.
The first question.
This audience is very direct.
Please adapt to their style.
Is the big data you talked about so great?
Can big data analyze stock accurately?
Can I get rich
by learning big data?
The idiom “get rich”
is close to life.
May you happiness and wealth.
I want to answer the last sentence first.
If you really learn
and master the big data,
you can get rich.
Do you know how much the salary
of big data engineers
or big data analysts is?
Higher than my salary.
But how much is your salary?
You need to give me
a basis for comparison.
Anyway, it’s high.
Yes, exactly.
Now the industry is short of
such big data analysts
because there is a lot of data
that needs to analyze
and our overall data application
is still in the primary stage
and far from
our expected goals.
As for the question
whether its analysis of stock is accurate,
I can tell you that,
a senior analyst
limited in a dark room
can accurately analyze the data
if he is only provided with data
and not allowed to
send out information.
The key point is that such information
can’t be shared,
or it’ll be inaccurate.
Yes.
Because it is an open system.
Right?
Sometimes it’s like
our traffic.
If there is a traffic jam somewhere,
all people hearing this…
would avoid that road,
but they get blocked in another road.
But the former road becomes smooth.
Exactly.
This open system
contains artificial factors
in the late period.
I guess, after you finished this sentence,
the enrollment number of big data major
of Beijing Institute of Technology
will increase greatly this year.
Welcome.
Everyone holds a plate
of getting rich
to learn it.
Next, I want to tell you all.
Now, “Voice”
has a special area
on the platform of CCTV
for live broadcast with texts and pictures.
So some netizens
will also ask you questions online.
Let's take a look.
Hello, Mr. Mei.
My question is:
After fervent discussion of the big data
in the society,
many students follow the trend blindly
and apply for related majors
in their collage entrance aspirations.
Will such behaviors have a bad influence
on the future development of this industry?
I guess
this audience
just chose this major.
Now he wants to
learn some news from you.
This question is very difficult to answer.
As I’m engaged in this profession,
I hope more people could choose it.
And now the society
is really short of talents in this area.
In another aspect,
I think any industry
should exist.
But we can’t make all people
squeeze on a road.
People could perform well
in any field.
The most important thing is to choose
what you like and what is suitable for you.
That’s to say,
it may be better for you
if your thinking way
and learning way
can be suitable for this industry.
In my personal opinion,
undergraduates shouldn’t determine
the profession too early.
In general,
the university
has not had
the past elite education model
but should emphasize general education
to lay solid foundation,
which may be more important.
It’s not too late to choose majors
in the late period of the undergraduate
or the graduate periods.
Yes.
Undergraduates
should absorb all knowledge
to try to stabilize
their knowledge structures
rather than choose one major only.
The next time is for six youth representatives.
Hello, Mr. Mei.
I am a doctoral student of big data application.
I will graduate two years later.
So I still have two years left
before I get to that stage of getting rich.
You always think about it.
It’s a great honor for me
to talk with you face to face.
Just now, you also said
our country
has put forward that
cyber space belongs to our territory
from the national strategic level.
And corresponding things such as
network attack and defense technology
have had complete and sound
national laws.
But personal (privacy) level
is less explored.
With the gradual development of information technology
we’re willing to give up a little bit of privacy
to get such good service.
But those who are engaged in big data
know that, with its development in depth and breadth,
the excavation result
and corresponding influence
are not known
by people.
It won’t know it either.
When it asks whether you agree to share your data,
you agree.
But the result
is uncontrollable.
So what do you think of
such a case?
First of all, any technological progress
is double-sided.
When technology brings
convenience and progress to us,
it also brings other problems.
Everyone still remembers Chaplin’s,
“Modern Times” which young people
might not have watched
and the workers on the assembly line?
It showed the dilemma brought to people
in the industrial age.
Countries all over the world are studying
how to protect data privacy.
But in fact, in terms of
the current technical system,
I think no technical solution
can really protect this so-called privacy.
Then true privacy protection
must be done by laws and regulations
in a legal system.
That is to say,
it must restrict behavior of vendors.
But now there is a problem.
If they are restricted too much,
the industry won’t be developed.
But if they are not restricted at all,
