　　Originally this article is prepared for 5.15 more, but the last week has been busy visa and work, no time to postpone, now finally have time to write learning Spark last part of the content.第10-11 is mainly about spark streaming and Mllib. We know that Spark is doing a good job of working with data offline, so how does it behave on real-time data? In actual production, we often need to deal with the received data, such as real-time

learning? Baidu Encyclopedia on Machine Learning has such a simple explanation: machine learning is a multidisciplinary interdisciplinary, involving probability theory, statistics, approximation theory, convex analysis, algorithm

that employs a scripting language similar to Lisp. In this library, all the statistics-related features you want are available in the R language, including some complex icons. The code in the Machine learning directory in CRAN (which you can think of as a third-party package from a machine brother) is written by a lea

: Task T: Chess Performance Standard P: Percentage of opponents defeated Training experience: With your own game or competition experience.Another example is autonomous driving: Task T: Driving on the freeway with a video sensor Performance Standard P: Average error-free mileage Training Experience E: Watch a series of images and driving instructions recorded during human driving.

of people often does not care in the article to show their own mathematical level, and may even be to simplify the expression of their own ideas proud. the problem of artificial intelligence is not a mathematical problem, not even a problem that can be solved by mathematics. The difficulty of many things in artificial intelligence is that we do not know where the nature of the difficulty is, and where the "problem" is. Once the "problem" is clear, it may not be difficult to solve. The second co
