aggregation in data mining

Data mining Aggregation IBM

2018-7-12 · 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. The argument can be the value of a column or a measure from the input model.

What is Data Aggregation?

2020-6-19 · Data aggregation is any process whereby data is gathered and expressed in a summary form. When data is aggregated, atomic data rows -- typically gathered from multiple sources -- are replaced with totals or summary statistics. Groups of observed aggregates are replaced with summary statistics based on those observations.
