If you want to buy a car, you have to have money.Accuracy VerificationFinally, let's verify the accuracy of today's clustering algorithm, and what is the difference between the decision tree algorithms in the previous article, we click into the data Mining accuracy chart:We can

, extensible, and optimized for query performance.9. The most active project in Spark--apache Software Foundation is an open source cluster computing framework.Spark is an open-source cluster computing environment similar to Hadoop, but there are some differences between the two that make spark more advantageous in some workloads, in other words, Spark enables the memory distribution dataset, in addition to providing interactive queries, It can also o

In the coming 2016, big data technology continues to evolve, and new PA is expected to adopt big data and Internet of things in many mainstream companies by next year. New PA finds that the prevalence of self-service data analytics, combined with the widespread adoption of c

A physical table above can put a lot of view charts, these tables unified management, unified heartbeat, unified an index, for external users of the query on the chart and the physical table query, there is no difference in use. With the view chart, the original need to create separate tables for those small businesses, the problem of bu
