Nettet17. mai 2024 · k-Nearest Neighbor (k-NN) is an instance-based supervised learning algorithm which classifies a new instance by comparing it with already stored instances in the memory that have already been seen in training. The class of an unknown instance is computed using the following steps: jayhawks irving plazaNettetlayer_add_instance(layer_id, near); The above code will first get the index of the nearest instance to the given x/y position and store it in a local variable.
