AIAI :
What sheer computing power can do

Thinks easy for man are difficult to put in equation
Deep Learning example:
Easy recognition can be taught to computer ... which will come up with statistical rules which match the given training sample
1) AI and Deep learning: example with image
recognition

Can you see a face in the picture ?
Image recognition
1) how supervised learning Algo work?
Black shape

Human face

But first some
training with labels
![Page 5: How ai work, Abstract for dummies based on excellent artilce from The Economist](https://reader038.fdocuments.net/reader038/viewer/2022110312/55b8e6b4bb61eb97088b472a/html5/thumbnails/5.jpg)
Within Facebook most
data are "prelabeled"
by users
"Great breakfast with TOM"

See where more "training is required"
Most of the time 95% correct is OK

Can define a new
categories: "I see a lot of this: tell me what it is !"
2) How unsupervised learning Algo
work?
Youtube lets AI scan
millions of video
( no pre-training with labels given)

... And then can be really good .... And tireless
Microsoft Cortana recognises the dog precise family

Yes easy to foul...
But see it

Did you over-look it ?

Progress of classical AI
thanks to sheer computing power
( Moore's law)

AI computing:
If ..... Then ......
classical computing :
if ... Then .... Else ....
go thru all your 10000 rules in 1/10 sec and writes 3000 pages
a sec
Precise reliable predictable outcome...
Or BUG.
Go thru your rules and give a possible
answer ...
Or ask for more question
Problem can be put in equation:Write it
Problem cannot be put in equation:
Just give rules
