WebConsider a nearest neighbor graph of MNIST. For example, consider a graph \((V,E)\) where the nodes are MNIST data points, and each point is connected to the three points that are closest to it in the original space. 3 This graph is a simple way to encode local structure and forget about everything else. WebThis function can either return a Neighbor object with the KNN information or a list of Graph objects with the KNN and SNN depending on the settings of return.neighbor and compute.SNN.
