Data mining normalization | Galaktikasoft

The data normalization (also referred to as data pre-processing) is a basic element of data mining. It means transforming the data, namely converting the source data in to another format that allows processing data effectively. The main purpose of data normalization is to minimize or even exclude duplicated data.


What is the lift value in association rule mining ...

800. 1000. Let us now evaluate the association rule Tea => Coffee. The support of this rule is 100/1000 or 10%. The confidence of the rule is 150/200 or 75%. At first sight, this association rule seems very appealing given its high confidence. However, closer inspection reveals that the prior probability of buying coffee equals 900/1000 or 90%.


What is Normalization in Data Mining and How to Do It ...

Applying the same understanding, we know that Recall shall be the ...



Measuring the Accuracy in Data Mining in SQL Server

Data mining is a predicting technique using the existing pattern. It is obvious that we won't be able to predict accurately. However, since we are using data mining outcomes for better business decisions, the result should have better accuracy. If the accuracy is very low, we tend not to use those data mining models.
