このため、[平均最近隣距離分析 (Average Nearest Neighbor)] ツールを使用すると、固定された分析範囲内のフィーチャ間の比較を非常に効果的に行うことができます。 以下の図は、指定された分析範囲によって、同じフィーチャの分布がクラスタリングされたり、分散されたりする典型的な例を示しま...
[平均最近隣距離分析 (Average Nearest Neighbor)]ツールでは、各フィーチャの重心と最近隣フィーチャの重心位置との間の距離が測定されます。次に、すべての最近隣距離の平均が計算されます。平均距離が、仮説的なランダム分布の平均よりも小さい場合、分析対象フィーチャの分布は...
After setting up the above parameters, click the “OK” image button in the dialog box to perform the Average Nearest Neighbor Analysis. The analysis results include the following five parameters: the nearest neighbor index, the expected mean distance, the average observation distance, z-score and...
The paper is focused on the analysis of average nearest neighbor degree (ANND) in complex social networks. The ANND of nodes with degree k is defined as the average degree of their neighbors over all nodes with degree k . ANND is one of the well-established tools for the analysis of ...
根据从每个要素到其最近相邻要素的平均距离计算最近邻指数。 了解有关“平均最近邻距离”工作原理的详细信息 插图 使用情况 平均最近邻工具将返回五个值:“平均观测距离”、“预期平均距离”、“最近邻指数”、z 得分和 p 值。 在工具执行期间,这些值会在地理处理窗格底部以消息的形式写入,并将作为派生输出值进行...
In this paper, we perform an average-case analysis of k-nearest neighbor classifier (k-NNC) for a subclass of Boolean threshold functions. Our average-case analysis is based on the formal computation for the predictive accuracy of the classifier under the assumption of noise-free Boolean features...

First, we calculate the poll's distance to the nearest survey using a k-nearest-neighbors algorithm. After removing any outliers via winsorizing, we then transform that distance into a probability, representing our confidence that the survey is indeed farther from its "nearest neighbor" survey ...
