CROWN III The Biggest Event in Human Historyk
The term “artificial intelligence” was first used by a group of scientists
who gathered at Dartmouth College in 1956. They @( idea / of / simulate

the) human intelligence. Ever since that time, scientists have
been making efforts to create such machines. According to Matsuo Yutaka,
an AI expert at the University of Tokyo. AI research has developed in three
stages. From the late 1950s through the 1960s, researchers A(on / could
/ and / play / computer / developing / puzzles / programs / that / concentrated
/ solve) board games. In the 1980s, they shifted their attention to
creating “expert systems,” programs designed to incorporate expert
knowledge into computers. In the 2010’s, B(systems / learn / own / to creating
/ their / could / researchers’ / on / shifted / which / interest),
systems with “machine learning” capabilities.
Machine learning has now reached a new stage with the development of “deep
learning.” Deep learning tries to replicate what is going on in human
brains. In other words, computer systems are becoming more like human neural
networks. Just as we learn by using neural networks, computer systems learn

Computer systems ⑤( never / have / a / we / dreamed / of / number

years ago. Object recognition is an essential human function―for
example, our capacity to see a cat and recognize it as such. Obviously,
this is very simple task for us humans, but not for a computer. Think about
the fact that no two cats are exactly the same―size, weight, colors
and shape of the tail vary widely. Thus, for a computer system to be able
to recognize a cat, it ⑥(some / characterize / differences / while
/ essential / be / features / focusing / must / to / ignore / on / able
/ which ) a cat.
In fact, in 2012 researchers at Google carried out an experiment where
the computer system received 10 million cat images from the Internet. The
neural networks ⑦(autonomously / abstracted / common / shared

) cat images, and then created a whole new cat.
If you are asked who painted the portraits shown below, you will most likely
to answer, “Rembrandt.” But the answer is not quite correct. Actually,
one was painted by Rembrandt, but the other was painted by a computer system.
A Dutch team ⑧(learning / in / that / style / could / the / create
/ an / “new” / built / a / work / deep / program / of / entirely) Rembrandt.
First, the computer system ⑨(learning / 346 / them / using / deep
/ and / scanned / all / of / Rembrandt’s / analyzed / technology / paintings).
Next, the computer was told what features should be incorporated in the
painting: the subject should be a 30- to 40-year -old male with a beard
and wearing a hat. Then, the computer processed the data and created a
fully formed face and bust in the style of Rembrandt. Finally, a 3-D printer,
using a deep learning program, painted the work. In the spring of 2016,
this new “Rembrandt” surprised art lovers all over the world.
Another feat of deep learning took place in the field of board games. In
March 2016, Alphago, software created by Demis Hassabis, surprised the
world by defeating Lee Sedol, a South Korean Go champion, by 4-1. This
⑩(rely / did / so-called / it / preprogramed, / on / nor / software
/ was / innovative / not) “brute force” search. Hassabis explains:
“Most AI programs are programed directly with the solutions, and then the
program executes that solution. With Alphago, it’s very different. We use
neural networks to allow Alphago to learn, first of all, by looking at
professional games and learning the kinds of patterns professional human
players make. And then it tries to get better than human players by practicing
through self-play―⑪(mistakes / of / own / learning / from /

mistake that leads to a loss, it will slightly change its system to make
the chance of that mistake slightly less in the future.”
