WHY I AM OPTIMISTIC Patrick H. Winston MIT Artificial Intelligence Laboratory
2
The salients Applications side: We have already won Science side: We are bound to win
3
The Applications
4
We have expanded our frontiers Lots of people Lots of good
5
A little good for a lot of people
7
A lot of good for a few people
8
A lot of good for a lot of people
9
We have exemplars of all kinds Large software companies Large entertainment companies Companies with huge IPOs Multidimensional multinationals A multitude of small companies
10
We were a one-horse field Rule chaining Inheritance
11
Now we ride many horses Rule chaining Generate and test Search Tree building Agents Neural nets Constraint propagation Inheritance Genetic algorithms Bayes nets Learning
12
And not just reasoning horses Vision Language and speech Infrastructure
15
We had a Pyrrhic victory IO Memory Cables Power Tapes Disk Network
16
We learned negative lessons Nobody cares about saving money Using cutting edge technology To replace expensive experts
17
We learned positive lessons Everybody cares about New revenues Saving a mountain of money Increasing competitiveness
18
We changed the business model Replaces Expensive People Saves Mountains Of Money Creates New Revenue Ferrets Blunder stoppers Novices Experts
19
The critic and the billionaire
20
What’s next: connections People Global Net Physical World Computers Enhanced Reality Intelligent Structures Useful robots Human Computer Interaction Information Access
21
The click-in phenomenon The fax machine The world wide web
22
The Science
23
Shrobe’s point Applications drive science Unless they all look alike
24
Atkeson’s point We could move to the center But, we might be kidding ourselves
25
My point AI is applied computer science Much energy wonderfully used But consequently diverted
26
A 100 year enterprise Molecular Biology Artificial Intelligence 1950200020501900
27
Why we are the way we are Powerful Ideas Models of Thinking Reflection…Biology…Psychology Turing Minsky
28
The Intelligent Reasoner LanguageVision Input/Output Channels The standard paradigm
29
The dawn age
30
What went wrong? We think with our eyes We think with our mouths We think with our hands Each faculty helps the others
31
What is the evidence? Armchair psychology Clues from the brain
32
Armchair psychology Hillis’s observation on the value of talking to yourself Everyone’s observation on the value of drawing a sketch.
33
From brain scanning
34
Intelligence is in the I/O The Explanation Motor Reasoner Linguistic Reasoner Visual Reasoner
35
Language is first among equals Language reasons Language tells vision how to see Language tells motor how to act
36
Is it time to start over? An I/O oriented paradigm Essentially free computation Important, inspiring allies
37
From brain rewiring
38
From watching infants
39
Is it time to start over? An I/O oriented paradigm Essentially free computation Important, inspiring allies Accumulation of powerful ideas
40
Six powerful ideas Recreated condition One-shot learning Memory is cheap Change matters Survival of the smallest Bi-directional search
41
Recreated condition: Minsky P / \ P P / \ P P / \ / \ P P P P / \ / \ / \ / \ P P P P P P P P / \ / \ / \ / \ / \ / \ / \ / \ P P P P P P P P *---------------------------------- | | K-line | *--------------> | *--------->
42
One-shot: Yip and Sussman aepl Time Word Memory Rule Memory
43
One-shot: Yip and Sussman aeplz Time Rule Memory Word Memory
44
One-shot: Yip and Sussman 100% Trials 500 Accuracy
45
Memory is cheap: Atkeson
46
Atkeson’s practice tables
47
Atkeson’s practice results One stored trajectory Feedback only Three stored trajectories
48
Change matters: Borchardt A D Appear Disappear Change Decrease Increase A D Appear Disappear Change Decrease Increase
49
Borchardt’s ladder diagrams DA DA AAA Distance Speed Contact T1T2T4T3
50
Survival of the smallest: Kirby
51
Kirby’s phase transitions Time Coverage
52
Bi-directional search: Ullman Model Image
53
Joyous inferences Powerful ideas Marvelous engineering Essential alliances
54
What about … Bayes and Markov Neural nets and connectionism Logic
55
WHAT WE MUST NOT DO
56
Loose our faith It will take 300 years All the low hanging fruit is gone We shouldn’t make predictions
57
Waste time arguing Is it possible? Is it successful? Is it really AI?
58
Squander our capital One thousand people 10% interested in the science side 10% actually working on it 10% of the time
59
WHAT WE SHOULD DO
60
Human Intelligence Enterprise Vision, language, motor Free hardware Clues from the brain Powerful ideas Conceive and test models The Human Intelligence Enterprise Visual Reasoner Linguistic Reasoner Motor Reasoner
61
Why we should do it It can only be done once Revolutionary applications The Human Intelligence Enterprise Visual Reasoner Linguistic Reasoner Motor Reasoner
62
What we should ask Why do we have discrete words? What do our inner agents say? How do they learn what to say? Do we see what chimps see? How did our faculties evolve? Why can’t we all play the piano? The Human Intelligence Enterprise Visual Reasoner Linguistic Reasoner Motor Reasoner
63
So, here is why I’m optimistic Nothing could possibly be more fun, exciting, rewarding, and glorious, than … Applications that really matter Figuring out our own intelligence The Human Intelligence Enterprise Visual Reasoner Linguistic Reasoner Motor Reasoner
