Aggregation methods are types of calculations used to group attribute values into a metric for each dimension value. For example, for each country (each value of the Country dimension), you might want to retrieve the total value of transactions (the sum of the Sales Amount attribute).
Data Mining Techniques Statistics Textbook. May 8, 2015, What is Data Mining (Predictive Analytics, Big Data), For example, uncovering the nature of the underlying functions or the specific types of, Data reduction methods can include simple tabulation, aggregation (computing.
This results into smaller data sets and hence require less memory and processing time, and hence, aggregation may permit the use of more expensive data mining algorithms. → Change of Scale: Aggregation can act as a change of scope or scale by providing a highlevel view of the data instead of a lowlevel view. For example,
Bagging. Bootstrap Aggregation famously knows as bagging, is a powerful and simple ensemble method. An ensemble method is a technique that combines the predictions from many machine learning algorithms together to make more reliable and accurate predictions than any individual means that we can say that prediction of bagging is very strong.
Basic aggregation. In most cases, aggregation means summing up the individual values. In general, aggregation is defined by an aggregation function and its arguments, the set of values to which this function is applied. The most common aggregation function is SUM. Other functions might also make sense, for example AVG or MAX.
