What is artificial intelligence ?
 artificial intelligence (Artificial 
Intelligence), The English abbreviation is AI, It's research , Develop theories to simulate and extend human intelligence , method , A new technology science of technology and application system .
2017  Year  17%  The developers of AI Or machine learning . also  73%  People said they planned to  2018  To learn these techniques .
■ 46%  's developers said they would probably be in  2018  Looking for a new job .
——DigitalOcean  report 
 With artificial intelligence (AI) It began to penetrate almost every industry , More and more developers are making plans to learn this technology to increase their business competitiveness .DigitalOcean  According to a survey , about  
83%  The developer of  2017  Not engaged in  AI  Or machine learning experience , But among them  73%  People said they planned to  2018  To learn these techniques .
 according to  ZDNet  It is reported that some companies, including Microsoft, have added artificial intelligence to their products , Make it easier for developers to integrate data , This also makes developers more familiar with these technologies .
 Investigation findings , stay  17%  Of  AI  Among developers , A lot of people use it  TensorFlow  Solving semantic analysis , Image recognition and natural language processing .
 Developers also want to  AI  Some problems can be solved in the coming year : When they were asked what they expected  2018  What are the major challenges facing the annual meeting ,63%  People think it's automated workflow ,32% 
 People think it's useful  AI  And machine learning to solve business needs .
 Participating in the survey  2500  Most developers use  Linux  operating system (89%), Much higher than Windows(8%),MacOS(2%) and  BSD(1%).
 In programming language selection ,PHP  suffer  27%  Of the respondents , The second is  Python(24%),Java(15%) and  Java(8%).LetsEncrypt 
 It's the most popular  SSL  provider , The second is Comodo(8%) and  GoDaddy(6%).
AI  Developers are one of the most needed professionals , Faced with high conditions and high salaries . Of the developers surveyed, about  46%  People said , They are likely to be there  2018 
 Take advantage of the popularity of the market to find a new job .
 Last century 50 At an academic conference in the S , At that time, several famous scientists discussed the problem of simulating human intelligence with machines from the perspective of different disciplines , For the first time “ artificial intelligence ” Terms for . from then on , The new subject of artificial intelligence was born .
 The academic conference , It's the Dartmouth conference in the history of computer science (Dartmouth Conferences).
 What are the applications of artificial intelligence ?
1. computer game 
2. intelligent robot 
3. Man machine game 
4. Face recognition 
 in addition , Artificial intelligence in natural language recognition , fingerprint identification , Map navigation , Automatic driving and other directions have made great contributions , I will not describe it here .
 What are the criteria for artificial intelligence ?
 To answer this question , We have to introduce another famous concept first : Turing test .
 Turing test is a famous scientist Alan · Matheson · Turing in 1950 Proposed in . Its content is , If the computer program can 5 Answer a series of questions from human testers within minutes , And it exceeds 30% The test takers were mistaken for human answers , Then the program passes the test , It shows that the program has the intelligence close to human .
 Give me a straight explanation ,
 Participants in the Turing test include one or more judges , Two testers . One of the testers was a human , Another tester is a computer program . ladder - Zero thirty | Ninety two | Do you want to order Kang , When the judges can't see the tester directly , Some questions raised by the judges , Then make your own judgment according to the answer . To this day , Only one smart chat program in the world barely passed the Turing test , Its name is  
 Eugene · Gustman . thus it can be seen , Human distance realizes artificial intelligence in real sense , There is a long way to go .
 artificial intelligence , machine learning , What is the relationship among deep learning ?
 In short , The relationship between the three is concentric :
 The outermost layer of concentric circles is artificial intelligence , From putting forward the concept to the present , There have been many kinds of realization ideas and algorithms .
 The middle layer of concentric circles is machine learning , It belongs to a subset of artificial intelligence , Many recommendation algorithms on the Internet , Correlation ranking algorithm , The foundation is machine learning .
 The innermost layer of concentric circles is deep learning , Further sublimation based on machine learning , It is the core driver of the big bang of artificial intelligence .
