Bagging and Bootstrap in Data Mining, Machine …
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 model.It means that we can say that prediction of bagging is very strong.
Data mining – Aggregation
2018-7-12 · Typically, many properties are the result of an aggregation. The level of individual purchases is too fine-grained for prediction, so the properties of many purchases must be aggregated to a meaningful focus level. Normally, aggregation is done to all focus levels. In the example of forecasting sales for individual stores, this means aggregation to store and day.
