Since AI is so intelligent that human can not be sure about its devolping direction.Music and Movie Recommendation Services While theyre rather simple when compared to other AI systems, apps like Spotify

12、,Pandora, and Netflix accomplish a useful task: recommending music andmovies based on the interests youve expressed and judgments youve madein the past. By monitoring the choices you make and inserting them intoa learning algorithm, these apps make recommendations that yourelikely to be interested i

13、n. Much of this functionality is dependent on human-assigned factors.For example, a song might have “driving bass,” “dynamic vocals,” and“guitar riffs” listed as characteristics; if you like that song, youllprobably like other songs that include the same characteristics.

The uses of AI in smart homes are limited only by our imagination.Security Surveillance A single person monitoring a number of video cameras isnt a very secure system; people get bored easily, and keeping track of multiple monitors ca

With supervised training exercises, security algorithms can take input from security cameras and determine whether there may be a threatif it “sees” a warning sign,

AI has a hug

21、e effect on your life, whether youre aware of it or not, and its influence is likely to grow in the coming years. Here are 10 examples of artificial intelligence that youre already using every day. Virtual Personal Assistants Siri, Google Now, and Cortana are all intelligent digital personal assista

22、nts on various platforms (iOS, Android, and Windows Mobile). In short, they help find useful information when you ask for it using your voice; you can say “Wheres the nearest Chinese restaurant?”, “Whats on my schedule today?”, “Remind me to call Jerry at eight oclock,” and the assistant will respon

AI is important in these apps, as they collect information on your requests and use that information to better recognize your speech and serve you results that are tailored to your preferences. Microso

24、ft says that Cortana “continually learns about its user” and that it will eventually develop the ability to anticipate users needs. Virtual personal assistants process a huge amount of data from a variety of sources to learn about users and be more effective in helping them organize and track their

27、es.Online Customer Support Many websites now offer customers the opportunity to chat with acustomer support representative while theyre browsingbut not every site actually has a live person on the other end of the line. In many cases, youre talking to a rudimentary AI. Many of these chat support bot

28、s amount to little more than automated responders, but some of them are actually able to extract knowledge from the website and present it to customers when they ask for it. Perhaps most interestingly, these chat bots need to be adept at understanding natural language, which is a rather difficult pr

29、oposition; the way in which customers talk and the way in which computers talk is very different, and teaching a machine to translate between the two isnt easy. But with rapid advances in natural language processing (NLP), these bots are getting better all the time.Language points1. assistant assist

The only thing is that there might be a few machine-learning problems when the first cars hit the market, so perhaps Id better learn to d

Of course, it could be very useful to have a more form of Al-a truly independent form of artificial intellige

39、nce, capable of exercising its own judgement, could help us solve many of the worlds problems. But have you ever thought about the risks? After all, why would an independent form of Al need to consider the opinions and of humans? We could be seen as asmallinconvenience thats in the way of a solution
