Spatial data mining refers to the theory, methods and techniques of extracting the hidden knowledge and spatial relations which are not clearly displayed from the spatial database and discovering the useful characteristics and patterns. The process of spatial data mining and knowledge discovery can be divided into several steps: Data preparation, data selection, data preprocessing, data reduction or data tr

The idea of self-taught machine learning is really because of my interest in data mining, because in my heart I have always believed in the logic that there is a certain pattern behind everything, and that different situations only correspond to certain conditions. So to find such a pattern is the most convenient and quickest way to solve a class of problems, as a lazy person like me, of course, I would like to use the most efficient way to solve the

[Introduction to Data Mining]-Introduction to data types and Data MiningData TypeDifferent datasets are manifested in many aspects. For example, attributes describing data objects can have different types: quantitative or qualitative. In addition, a dataset may also have a specific nature, such as a time series or associated with each other. This is because the data type determines what tools and technologies should be used for data analysis. In addit
