Therefore, an appropriate number of nearest neighbors is critical for the k-NN classifier. However, in present, there is no systematical solution to determine the specific value of k. In order to address this problem, we propose a novel method of using back-propagation neural networks to ...
To determine the number of nearest neighbors and next nearest neighbors of an Na+ ion in a crystal of NaCl, we will analyze the structure of NaCl and identify the positions of the ions. 1. Understanding the Structure of NaCl: - NaCl crystallizes in a face-centered cubic (FCC) lattice str...
If the size of data set is large, the sequential or binary search of NNs is inapplicable due to the increased computational costs. Therefore, indexing schemes are frequently used to speed-up the classi?cation process. If the required number of nearest neighbors is high, the use of an index...

It was configurable with the default k=10 before, now it uses n_neighbors from sc.tl.neighbors. As discussed with @falexwolf . Koncopd requested a review from falexwolf March 17, 2020 10:23 falexwolf mentioned this pull request Mar 17, 2020 TODO: Backwards-compat breaking changes #...
Spheres in colloidal clusters obtained from numerical quenching were colored in shades of green according to the number of nearest neighbors (first peak of the radial distribution function) to highlight surface features. Free energy calculation Absolute free energy of a colloidal cluster at packing ...

Comparable to the [Fe/MgO]4 sample, different switching fields are observed for the even and odd innermost layers, even though the number of nearest neighbors is identical. Increasing the number of Fe layers to eight also results in a decrease in the highest and the lowest switching fields (...
