explore the potential value of data.relational database management systems and desktop statistics tools and visualization packages often have problems dealing with big data. Requiring a lot of parallel software running on thousands of servers requires new processing to support decision-making value discovery and process optimizationThe

... 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 see that today's cluster analysis algorithm, the score is 0.72, than the previous decision tree algorithm 0.87, or a slight gap, of course, can not only score to evaluate

With the deep application of big data in various fields, the value of big data itself is also highlighted. Researchers and commercial users analyze big data to gain insight into the real needs of customers.

Excerpted from Chapter 14 "Big Data daily notice: Architecture and algorithms", the book directory is here for massive data to be mined, in a distributed computing environment, the first problem is how to evenly distribute data to different servers. For non-graph data, this

like ORACLE,EMC are not sitting idly by and waiting for their markets to be embezzled by open source software. Like EMC, the HAWQ system has been launched, claiming it is more than 10 times times faster than Impala, and Amazon's redshift offers better performance than Impala. Although open source software because of its strong cost advantage and has a very strong power, but the traditional database manufac
