Approximate nearest neighbor searchAugmented neighborhood graphBridge vectorsHamming spaceRecent years have witnessed growing interests in computing compact binary codes and binary visual descriptors to alleviate the heavy computational costs in large-scale visual research. However, it is still computationally ...
the Fukunaga and Narendra algorithm, and its application to chromosome recognition. Also, to compensate the increasing in error rates that approximate search produces, we propose to use a recently proposed framework to classify usingkneighbours that are not always theknearest neighbours...
The nearest neighbor search was repeated for all the newly assigned fcc lattice sites. The process was repeated until no more atoms could be assigned to the lattice. Second, new fcc lattice vectors were fitted (fitting parameters: translation, 3D rotation, and lattice constant) to the atoms ...
In lines 33-34, using the indices obtained from the nearest neighbor search, the corresponding control unit is identified and its outcome value is retrieved. The difference between the treated outcome and the matched control outcome is then computed and added to the ATT variable, as shown in ...
(f) The nearest and the next-nearest neighbor search was repeated for all the newly assigned bcc lattice sites. This process was repeated until no further atoms could be assigned to the lattice. (g) New bcc lattice vectors were fitted to the atoms assigned to the lattice using fitting param...

《The role of local dimensionality measures in benchmarking nearest neighbor search》阅读理解与总结 一、研究内容 该论文主要探索最近邻搜索的相关问题,即给定一个数据集S⊆M,在S上建立索引,对于查询点x∈M,返回距离度量D标准下S中最近的k个点,即与查询点最相关的K个关键字。实验选用局部内在维数(LID),...
When there is no more searching to perform, return the object nearest to the probe point. Listing One includes the code for functions that implement the search for the nearest neighbor search. The code is divided into a public and a private portion so that the user can input aconstvalue fo...
A related problem is the nearest neighbor search in the metric space [18], [19], [20]. Unfortunately, since the pairwise RTTs often violate the triangle inequality that is assumed to hold in a metric space [21], it is infeasible to apply Background In this section we first explain ...
For each cell profiled by snATAC-seq, we identified the nearest neighbor cell in those profiled by scRNA-seq with a nearest-neighbor search in the joint canonical correlation (CCA) L2 space. Nearest neighbors were determined by the ‘FNNʼ R package with the ‘kd_treeʼ algorithm. ...
