Data mining – Aggregation - IBM

2018-7-12  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

Data Mining: Data Aggregation

Data aggregation is our first data cleaning strategy. Aggregation is combining two or more attributes (or objects) into a single attribute (or object).

What is Data Aggregation? - Definition from Techopedia

2021-3-14  What Does Data Aggregation Mean? Data aggregation is a type of data and information mining process where data is searched, gathered and presented in a report-based, summarized format to achieve specific business objectives or processes and/or conduct human analysis. Data aggregation may be performed manually or through specialized software.

2005-7-1  The impact of data aggregation on the performance of data mining algorithms is of particular relevance to business data within a data warehouse, which we define here as a repository of data that is clean, integrated, complete, and summarized and thus “sets the stage for effective data mining”.

An efficient aggregation scheme resisting on

2020-7-1  In this section, we propose an efficient data aggregation scheme for resisting malicious data mining attack in the smart grid, which consists of five phases: system initialization, user reports generation, data aggregation, verification and decryption of aggregated ciphertext.

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.

A new data aggregation approach for WSNs based on

Since we consider and draw some grooves in different depths in our aggregation method around the central node, the aggregation plan is similar to an open-pit mining, so the proposed method is called the Open-pit mining based data aggregation. The proposed mining data aggregation method consists of several steps as shown in Table 2.
