Recommendation system and STING
STatistical Information Grid (STING) is a grid-based clustering algorithm. The dataset is recursively divided into a hierarchy structure. The whole input dataset serves as the root node in the hierarchy structure. Each cell/unit in a layer is composed of a couple of cells/units in the lower layer. An example is shown in the following diagram:
To support the query for a dataset, the statistical information of each unit is calculated in advance for further processing; this information is also called statistics parameters.
The characteristics of STING algorithms are (but not limited to) the following:
- A query-independent ...
