Spatial data mining is a mining of knowledge from large amounts of spatial data. It is a highly demanding field because huge amounts of spatial data have been collected in various applications, ranging from rem
Spatial data mining is the application of data mining to spatial models. In spatial data mining, analysts use geographical or spatial information to produce business intelligence or other results. This requires specific techniques and resources to get the geographical data into relevant and useful forma...

Prediction of a random field based on observations of the random field at some set of locations arises in mining, hydrology, atmospheric sciences, and geography. Kriging, a prediction scheme defined as any prediction scheme that minimizes mean squared prediction error among some class of predictors ...
There are numerous association rule algorithms have been developed for mining association. Unfortunately, the most algorithms can only used for mining non-spatial and specific formatted data. Therefore, spatial data preprocessing is needed in order conventional association algorithms can be used for ...
Global presence of Bitcoin mining activity. All mining locations detected (n = 6062) are mapped by their unique longitude and latitude coordinates. Details of each location are provided in Supplementary Table S2. The results are based on the monthly data from June 2018 to May 2019. The ma...

With the rapid expansion of data, the problem of data imbalance has become increasingly prominent in the fields of medical treatment, finance, network, etc. And it is typically solved using the oversampling method. However, most existing oversampling met
