WebExpert Answer. Transcribed image text: 3. In this problem, you will perform K-means clustering manually, with 2 K-2, on a small example with n = 6 observations and p features. The observations are as follows 5 62 6 (a) Plot the observations (b) Randomly assign a cluster label to each observation. You can use the sample () command in R to do this. WebSupervised learning: predicting an output variable from high-dimensional observations¶. The problem solved in supervised learning. Supervised learning consists in learning the link between two datasets: the observed data X and an external variable y that we are trying to predict, usually called “target” or “labels”. Most often, y is a 1D array of length n_samples. ky vs iowa point spread
