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

2005-7-1 If the detail data is aggregateable, then aggregation can be performed within a data preparation phase for data mining, with the advantage of utilizing the whole data in the mining process. Aggregation in our experiment also lead to more parsimonious models as it smoothed out some of the noise in the detail data.

2005-4-1 For order batching, the association rule mining is employed to discover associations between customer orders in the order database. Therefore, the order-item data table (e.g. Table 1) is transposed to the item-order data table (see Table 2) since the order correlation relationships are required rather than the product item relationships. The order batching problem can be adequately transformed to take a

2020-7-1 By using secure data aggregation techniques, the gateway first aggregates the n encrypted metering data into one encrypted value, and then send it to the control center. After decrypting, the control center can only obtain the aggregation results (e.g., sum, average) but not the individual metering data.

2021-5-7 When you need your summaries in the form of new data, rather than reports, the process is called aggregation. Aggregated data can become the basis for additional calculations, merged with other datasets, used in any way that other data is used. Here’s an example of a data aggregation

Data fusion methods are useful tools in data mining and knowledge discovery to build models of the data and to extract useful information from raw data. This work is devoted to one family of aggregation operators. The so-called, quasi-weighted means. In this work we present a methodology to learn the weights for these operators based on active set methods and the gradient descent.

2020-9-12 In technical terms, data mining is the process used to collect and extract data from a larger set of data to discover patterns and generate rules. Moreover, it is regarded as a discipline under the field of data science where it is distinguished from predictive analytics for its description of historical data; whereas the latter aims to predict ...
