WebStep 1: Choose the number of K neighbors, say K = 5. Step 2: Take the K = 5 nearest neighbors of the new data point according to the Euclidian distance. Step 3: Among these K neighbors, count the members of each category. Step 4: Assign the new data point to the category that has the most neighbors of the new data point. Here it is the red ... Web30 mrt. 2024 · The other three presets—cosine, cubic, and weighted k NN—are the subtypes of medium k NN (10 number of nearest neighbors) with the difference of distance metric and distance weighting functions. Cosine and cubic k NN use cosine and Minkowski (cubic) distance metrics, respectively, with no distance weighting function or equal weights.
