-Nearest Neighbors,N classifier with majority vote and the .-NN regressor with arithmetic mean. The effect of overfitting is illustrated via several examples. We introduce some preprocessing methods and then generalize the initially mentioned setting of metric spaces to distance measures in order to include cosine sim

Best-Fit Subspaces,ethod of least squares from Chapter ., but this time all coordinates of the data points are considered (and not only those designated as labels). By reformulating the initial minimization problem into a maximization problem, we present the greedy algorithm for calculating a best-fit subspace.
