thinking of a typical big data. They connect with each other to form neural networks that receive information from outside the body through sensory organs and nerves (in neural network algorithms we call training) to transmit the central nervous system, then through the analysis and synthesis of information, and then through the motor nerve to send control information (such as I hit the blog in the text),
on the RDD, such as the classic WordCount program, which operates as shown in the Spark programming model: You can see that spark first abstracted from the file system RDD1, and then by RDD1 through the flatmap operator to RDD2,RDD2 then Reducebykey operator to get RDD3, finally the data in the RDD3 back to the file system, all operations are based on RDD.Iii. Ideas and architectureAfter a lot of thinking, the final decision based on spark technolog

We can use this statement:Here we filter the maximum and minimum pages for subsequent mining. We change this statement to the

They can be applied to the customer-centric enterprise decision analysis and management of different areas and stages. ① Association Analysis Association analysis, that is, using association rules for data mining.

similar questions, such as "which customer is most likely to respond to our company's email promotions" and why. Some data mining tools can also solve some traditional problems that consume a lot of manual time, because they can quickly browse the entire database and find some extremely useful information that experts are not aware. Therefore, the success of CRM lies in successful data warehouses,
As I needed to train my colleagues on database indexing knowledge, I collected and sorted out this series of blogs. This is a summary of index knowledge. After summing up, I found that many vague concepts were much clearer in the past. Whether it is cached data information or physically saved information, their basic unit is
according to a certain pattern, these data sources correspond to the data in the Data warehouse and the conversion rules are stored in the metadata knowledge base; On the other hand, in the process of data Warehouse project implementation, it is often time-consuming and lab

Read "Data Mining Technology (third edition)"-Thoughts on marketing, sales and customer relationship management This book is not a purely data mining theory book, you can probably guess from the subtitle of this book. For a layman like me in the field of data mining, there is not much difficulty in reading this book.
. Some system calls only support fixed memory requests and their multiples (allocated by PAGE). This will cause a waste for a large number of small memory categories.2. System Call memory application may be expensive. System calls may involve switching between user and core states.3. Unmanaged memory allocation can easily cause memory fragmentation when a large amount of complex memory is allocated and released. Stack and stack comparisonFrom the above knowl
