--- title: "nearest neighbor method" source: https://www.jemoka.com/posts/kbhnearest_neighbor_method/ --- A very simple machine learning method. For some input \(\qty (\hat{x}, \hat{y})\), find the closest training data point \(\qty (x_{i}, y_{i})\) and return its associated \(z_{i}\), with error \(\mid z_{i} - \hat{z}\mid\). Consider a Voronoi Diagram! This surface is piecewise constant. see also nearest neighbor method and data interpolation
