Original: (original) Big Data era: a summary of knowledge points based on Microsoft Case Database Data Mining (Microsoft Naive Bayes algorithm)This article is mainly to continue on the two Microsoft Decision Tree Analysis algorithm and Microsoft Clustering algorithm, the use of a more simple analysis algorithm for the target customer group mining, the same use of

of the most want to buy a car of the characteristics of the silver, tomorrow continue to analyze, and see can help me to simple analysis, the same first a few of the structure of the picture:Tomorrow night the results are analyzed, and the characteristics of the two algorithms are compared and analyzed. Be interested in big data don't forget your "recommendation" Oh.The power of

the Java implementation of the Big Data bitmap method (no repetition , repetition, deduplication, data compression)Introduction to Bitmap methodThe basic concept of a bitmap is to use a bit to mark the storage state of a data, which saves a lot of space because it uses bits to hold the

When selecting a product for deduplication, you 'd better consider the following ten questions. When a storage product provider releases a deduplication product, how can it locate its own product? Do you have to think about the following questions? 1. What is the impact of deduplication on backup performance? 2. Will deduplication reduce data recovery performance? 3. How will capacity and performance expansion grow with the environment? 4. How

Compared with the previous information production methods, big data has three obvious features: large data volume, non-structural and real-time data, which creates an infinite world of possibilities. Enterprises are establishing and applying big

Data visualization technology can help people to understand the large amount of data information and discover the laws hidden in the data, so as to improve the efficiency of the data using the visual thinking ability of the human brain. In the face of big Data's profundity,

Technology to a certain extent, and gradually find their own bottlenecks. Can't help but start to think about this aspect of the problem! In the big Data age, is the corresponding data analysis technology important, or the corresponding data thinking important?Let's start with data
