0.0 Course overview

Artificial intelligence > machine learning > Deep learning .

That's true . There are too many principles , The code can't keep up .

This learning curve is very interesting , First time to see .

It turns out that these foundations are enough ,nice.

This is the learning objective of this course .

The program of this course .

1.1 The birth of artificial intelligence

• Turing machine ： Provides the soul of modern computers . Now all computer models are based on Turing machines .

Turing machine model . As long as a problem is decidable , Its calculation process can be expressed by symbols and algorithms , The Turing machine can be used to complete the calculation .

Turing test . Verification Code Captcha

ppt Dry cargo is full. , The screenshot is recorded as follows .

1.2 The development of artificial intelligence

Three waves of artificial intelligence . Three rises and two falls .

Reasoning period （ Proof of principle ）-> Period of knowledge （ expert system . The experts summed up the rules ）-> Machine learning period （ Deep learning , Learn the rules by yourself ）

Statistical machine learning .

After listening to this section , Have a further understanding of the development of artificial intelligence . a key PPT The screenshot is as follows

1.3 Brilliant wit or Not as skilled as a man

Artificial intelligence is applied to man-machine chess .

The concept of machine learning is also put forward in this process .

The second wave ：1997 year ,IBM Deep blue , supercomputer . The knowledge base + Search for

The third wave ：2006 year 3 month ,Google DeepMind,Alpha Go Defeat Li Shishi .

2017 year 5 month ,Alpha Go Master Defeat Ke Jie 3:0.

Hinton say ： Artificial intelligence will no longer have a cold winter , Because it's already in your cell phone . Face recognition . fingerprint identification . TaoBao , Baidu translation , WeChat , headlines , Intelligent assistant . AI is everywhere .

Weak artificial intelligence and Strong artificial intelligence .

It is predicted that 2029 In, there will be artificial intelligence that can pass the Turing test . People in the abiotic sense , There will also be .

Whether artificial intelligence can surpass human beings , I feel it is possible .

Terror is like this .
