RBush is a high-performance JavaScript library for 2Dspatial indexingof points and rectangles. It's based on an optimizedR-treedata structure withbulk insertionsupport. Spatial indexis a special data structure for points and rectangles that allows you to perform queries like "all items within this...
In this work, we propose an alternative approach to produce efficient and high-quality agglomerates based on R-trees [43], [50], a spatial indexing data structure. R-trees excel at organizing spatial data using bounding boxes, particularly in contexts where performing spatial queries for large ...
We propose TEDI, an indexing for solving shortest path, and k Nearest Neighbors (kNN) problems. TEDI is based on the tree decomposition methodology. The graph is first decomposed into a tree in which the node contains vertices. The shortest paths are stored in such nodes. These local shortest...

In order to retrieve similar motion data from Mocap database, each human joint’s motion clip is regarded as a bag, while each of its segments is regarded as an instance. 3D temporal-spatial features are extracted and data driven decision trees are autom

3.4. Associativity Reconfigurable Cache By changing the indexing policy, cache blocks that originally belonged to two d8iofffe1r7- ent ways are concatenated to tune the associativity from four to two. Figure 7 illustrates the associativity reconfigurable cache with fixed cache size. Algorithms 2021, ...
