' past ' and ' Now ' what's happening ' and ' what's going to happen ' is a functional category of DM platform (data mining, such as SPSS), and the DM platform predicts future business by building predictive models to help companies answer questions about what might happen in the future.The enterprise's full range of data analysis capabilities is shown in the fo

Data mining-how to make it better (as I expected)Because I didn't even make it well, I just thought about the problems I encountered and how to solve them! Recently, this may be due to the high-dimensional reasons. Most of the theories and examples in the book are low-dimensional (less than 100). The theory is perfect, but all problems come out in practice, and there are a lot of problems .................

Data Mining is effective, novel, and potentially useful from massive, incomplete, noisy, fuzzy, and random data sets, and the extraordinary process of an understandable model. It is a wide range of cross-discipline, including Machine Learning , Mathematical Statistics , Neural Network , Database , Pattern Recognition , Rough Set , Fuzzy Mathematics And oth

rules can only happen by chance, and support is often used to remove meaningless rules. Also has an expected nature that can be used for association rule discovery.　　Confidence level (c):The confidence level of an association rule is defined as: This definition determines how frequently y appears in a transaction that contains X. or see {Bread,milk}→{diaper} This example, the transaction containing the {Bread,milk} item has occurred 2 times, the transaction containing {Bread,milk,diaper} has oc
