0:06 - 0:15When I was a boy I wanted to maximize
my impact on the world and I was -
0:15 - 0:24smart enough to realize that I am
not very smart and that I have to build -
0:24 - 0:30a machine that learns to become
much smarter than myself such that it -
0:30 - 0:35can solve all the problems that I
cannot solve myself and -
0:35 - 0:36I can retire.
-
0:37 - 0:45And my first publication on that dates
back 30 years 1987 my diploma thesis where -
0:45 - 0:50I already try to solve the grand problem
of AI not only build a machine that learns -
0:50 - 0:56a little bit here and learns a little bit
there but also learns to improve the -
0:56 - 1:03learning algorithm itself and the way it
learns the way it learns and so on -
1:03 - 1:13recursively without any limits except
the limits of logics and physics and -
1:13 - 1:16I'm still working on
the same old thing and I'm -
1:16 - 1:25still pretty much saying the same thing
except that now more people are listening -
1:25 - 1:30because the learning algorithms that we
have developed on the way to -
1:30 - 1:35this goal they are now on
three thousand million smartphones and all -
1:35 - 1:41of you have them in your pockets what you
see here are -
1:41 - 1:45the five most valuable companies of the
-
1:45 - 1:48Western world Apple Google Facebook
-
1:48 - 1:57Microsoft and Amazon and all of them
are emphasizing that AI -
1:57 - 2:05artificial intelligence is central to what
they are doing and all of them are using -
2:05 - 2:11heavily the deep learning methods that
my team has developed since -
2:11 - 2:16the early nineties and yone in Munich and
in Switzerland especially something which -
2:16 - 2:22is called so long short term memory has
anybody in this room ever heard of -
2:22 - 2:28the long short-term memory or
the LST M hands up anybody ever heard -
2:28 - 2:37of that okay has anybody never heard of
the STM I see we have a third group in -
2:37 - 2:53this room who didn't understand
the question the lsdm is a little bit like -
2:53 - 2:55your brain it's
an artificial neural network which -
2:55 - 3:01also has neurons and in
your brain you've got about -
3:01 - 3:06100 billion neurons and each of them
is connected to roughly -
3:06 - 3:1310,000 other neurons on average which
means that you have got -
3:13 - 3:20a million billion connections and each of
these connections has a strength which -
3:20 - 3:24says how much does this neuron over
here influence that neuron over there at -
3:24 - 3:29the next time step and in the beginning
all these connections are random and -
3:29 - 3:34the system knows nothing within through a
smart learning algorithm it learns from -
3:34 - 3:42lots of examples to translate
the incoming data such as video through -
3:42 - 3:48the cameras or audio through
the microphones or pain signals through -
3:48 - 3:53the pain sensors it learns to translate
that into output actions because some of -
3:53 - 3:55these neurons are output neurons that
control -
3:55 - 4:03speech muscles and finger muscles and only
through experience it can learn to solve -
4:03 - 4:13all kinds of interesting problems such as
driving a car or do the speech recognition -
4:13 - 4:17on your smartphone because whenever you
take out your smartphone an -
4:17 - 4:22Android phone for example and you speak to
it and you say ok Google show me is -
4:22 - 4:28the shortest way to Milano then it
understands your speech because there is -
4:28 - 4:31an lsdm in there which
has learned to understand -
4:31 - 4:33speech every 10 milliseconds
-
4:33 - 4:40100 times a second new inputs are coming
from the microphone and then translates it -
4:40 - 4:49after thinking into letters which is then
question to the search engine and it has -
4:49 - 4:54long to do that by listening to lots of
speech from women from me all kinds of -
4:55 - 4:57people and that's how since
-
4:57 - 5:012015 Google speech recognition is
now much better than it used to be -
5:02 - 5:08the basic lsdm cell looks like that I
don't have the time to explain that but at -
5:08 - 5:14least I can list the names of
the brilliant students in my lab who made -
5:14 - 5:18that possible and what are
the big companies doing with -
5:18 - 5:26that well speech recognition is only
one example if you are on Facebook is -
5:26 - 5:29anybody on Facebook okay I
use sometimes clicking at -
5:29 - 5:33the translate button because somebody sent
you something in a foreign language and -
5:33 - 5:38then you can translate it is anybody
doing that yeah whatever you do that you -
5:38 - 5:42are waking up again
a long short term memory and lsdm which -
5:42 - 5:49has learned to translate text in
one language into translated text and -
5:49 - 5:57Facebook is doing that four billion times
a day so every 50 every second -
5:57 - 6:0350,000 sentences are being translated by
an LST am working for -
6:04 - 6:06Facebook and another 50,000 in the
second and another -
6:06 - 6:1350,000 and to see how much this thing
is now permitting the modern world -
6:13 - 6:21just note that almost 30 percent of
the awesome computational power for -
6:21 - 6:24interference and all these Google Data
-
6:24 - 6:29Centers all these data centers of Google
are all over the world is used for LST on -
6:29 - 6:32almost 30 percent if you have an
-
6:32 - 6:39Amazon echo you can ask a questions and it
answers you and the voice that you hear -
6:39 - 6:43it's not a recording it's
an LS TM network which has learned from -
6:43 - 6:54training examples to sound like
a female voice if you have an iPhone and -
6:54 - 6:57you're using
the quick type it's trying to predict what -
6:57 - 7:00you want to do next given
all the previous context of what you did -
7:00 - 7:05so far again that's an LS DM which
has to do that so it's on -
7:05 - 7:15a billion iPhones you are a large audience
by my standards but when we started -
7:15 - 7:22this work decades ago in the early
90s only few people who were interested -
7:22 - 7:26in that because computers were so slow and
you couldn't do so much with it and I -
7:26 - 7:33remember I gave a talk at
a conference and there was just -
7:33 - 7:37one single person in the audience
a young lady I said young lady it's -
7:38 - 7:42very embarrassing but apparently
today I'm going to give this talk just to -
7:42 - 7:54you and she said okay but please hurry I
am the next speaker since then we -
7:54 - 8:01have greatly profited from the fact
that every five years computers again in -
8:01 - 8:06ten times cheaper which is
an old trend that has held since 1941 at -
8:06 - 8:12least since this man Conrad Susan built
the first working program control computer -
8:12 - 8:20in Berlin and he could could do roughly
one operation per second one and then -
8:20 - 8:26ten years later for the same prize one
could do 100 operations 30 years later -
8:26 - 8:301 million operations were
the same price and today after 75 years we -
8:30 - 8:35can do a million billion times as much for
the same price and the trend is not about -
8:35 - 8:44to stop because the physical limits are
much further out there rather soon and not -
8:45 - 8:49so many years or decades we will for
the first time have -
8:49 - 8:55little computational devices that
can compute as much as a human brain and -
8:55 - 8:59this a trend doesn't break 50 years
later there will be -
8:59 - 9:04a little computational device for
the same price that can compute as much as -
9:04 - 9:10all 10 billion human brains taken
together and there will not only be one of -
9:10 - 9:13those devices but
many many many everything -
9:13 - 9:18is going to change already in
2011 computers were fast enough such that -
9:18 - 9:22our deep learning methods for
the first time could achieve -
9:22 - 9:28a superhuman pattern-recognition result and
was the first superhuman result and -
9:28 - 9:32the history of
computer vision and back then computers -
9:32 - 9:36were 20 times more expensive than today so
today for the same price we can do -
9:36 - 9:4520 times as much and just a few five years
ago five years ago when computers were -
9:45 - 9:5010 times more expensive than today we
already could win for the first time -
9:50 - 9:54medical imaging competitions what you see
behind me is a slice through -
9:54 - 10:00the female breast and the tissue that you
see there has all kinds of -
10:00 - 10:05cells and normally you need
a trained doctor a trained the solid who -
10:05 - 10:10is able to detect
the dangerous cancer cells or -
10:10 - 10:15pre-cancer cells now our stupid network
knows nothing about cancer knows nothing -
10:15 - 10:19about vision it knows nothing in
the beginning but we can train it -
10:19 - 10:25to imitate the human teacher
the doctor and it became as good or better -
10:25 - 10:31than the best competitors and
very soon all of medical diagnosis -
10:31 - 10:36is going to be superhuman and
it's going to be mandatory because -
10:36 - 10:42it's going to be so much better than
the doctors after this all kinds of -
10:42 - 10:48medical imaging startups
were founded focusing just on this because -
10:48 - 10:54it's so important we can also use lsdm
to train robots one important thing I -
10:54 - 11:01want to say is that we not only have
systems that slavishly imitate what humans -
11:01 - 11:09show them no we also have a eyes that set
themselves their own goals and -
11:09 - 11:14like little babies invent
their own experiment to explore -
11:14 - 11:19the world and to figure out what you
can do in the world without a teacher and -
11:19 - 11:23becoming more and
more general problem solvers in -
11:23 - 11:28the process by learning new skills on top
of old skills and this is going to -
11:28 - 11:34scale we call that artificial curiosity or
a recent password is power plain -
11:34 - 11:39learning to become a more and
more general problems over by -
11:40 - 11:44learning to invent like a scientist
one new interesting goal after -
11:45 - 11:50Nathan and and it's going to scale and I
think in not so many years from now for -
11:50 - 11:56the first time we are going to have
an animal like -
11:56 - 12:01AI you don't have that yet on the level of
a little crowd which -
12:01 - 12:07already can learn to use two worlds for
example little monkey and once we have -
12:07 - 12:11that it may take just a few decades to do
the final step towards -
12:11 - 12:17human level intelligence because
technological evolution is about -
12:17 - 12:22a million times a million times faster
than biological evolution and -
12:22 - 12:30biological evolution needed
3.5 billion years to evolve a monkey -
12:30 - 12:34a monkey from scratch but then just
a few tens of millions of years -
12:34 - 12:39afterwards to evolve
human level intelligence we have -
12:39 - 12:43a company which is called Mason's
like birth in English -
12:43 - 12:47Mason's but spelled in
a different way which is trying to make -
12:47 - 12:51this a reality and build
the first true general and purpose AI at -
12:53 - 13:00the moment almost all research in AI is
very human centric and it's all about -
13:00 - 13:06making human lives longer and
healthier and easier and making humans -
13:06 - 13:12more addicted to their smartphones but
in the long run a eyes are going to -
13:12 - 13:17especially the smart ones are going to set
themselves their own goals and I have -
13:17 - 13:22no doubt in my mind that they
are going to become much smarter than we -
13:22 - 13:26are and what are they going to do of
course they are going to realize what we -
13:26 - 13:31have realized a long time ago namely that
most of the resources in -
13:31 - 13:38the solar system or in general are not in
our little biosphere they are out there in -
13:38 - 13:44space and so of course they
are going to emigrate and of course they -
13:44 - 13:53are going to use trillions of
self-replicating robot factories to expand -
13:54 - 13:57in form of growing
-
13:57 - 14:01AI bubble which within a few
hundred thousand years is going to cover -
14:01 - 14:07the entire galaxy by senders and receivers
such that a eyes can travel the way they -
14:07 - 14:16are already traveling in my lab by radio
from sender to receiver Wireless so what -
14:16 - 14:23we are witnessing now is much more than
just another Industrial Revolution this is -
14:24 - 14:29something that transcends
humankind and even life itself -
14:29 - 14:35the last time something so important
has happened was maybe 3.5 billion years -
14:35 - 14:42ago when life was invented a new type of
life is going to emerge from -
14:42 - 14:46our little planet and
it's going to colonize and transform -
14:47 - 14:52the entire universe the universe is
still young it's only 13.8 billion years -
14:52 - 14:58old it's going to become much older than
that many times more many times older -
14:58 - 15:03than that so there's plenty of time
to reach all of it or all of -
15:03 - 15:09the visible parts totally within
the limits of light speed and physics -
15:10 - 15:15a new type of life is going to make
the universe intelligent now of course we -
15:15 - 15:22are not going to remain the crown of
creation of course not but there is still -
15:22 - 15:29beauty in seeing yourself as part of
a grander process that leads the cosmos -
15:29 - 15:36from low complexity towards
higher complexity it's a privilege to live -
15:36 - 15:40at a time where we can
witness the beginnings of that and where -
15:40 - 15:50we can contribute something to
that thank you for your patience
