  • Hierarchical tree data structures and uses thereof
    Patent number: 11093473
    Abstract: Methods and systems are disclosed for generating and using a hierarchical tree data structure. A computing device may receive data having a number of dimensions and corresponding values for each of the dimensions. A hierarchical tree data structure may have a root node and a number of levels, one of which may be connected to the root node. Each level may correspond to a respective dimension of the data and may be connected to a higher level as well as to a lower level. A measure for a given dimension may be evaluated based on the nodes corresponding to the level that corresponds to the given dimension and all preceding connected nodes. A result of the measure may be stored in a number of nodes corresponding to the level that corresponds to the given dimension.
