WebSep 10, 2024 · ABC. We are keeping it super simple! Breaking it down. A supervised machine learning algorithm (as opposed to an unsupervised machine learning algorithm) is one that relies on labeled input data to learn a function that produces an appropriate output when given new unlabeled data.. Imagine a computer is a child, we are its supervisor (e.g. … WebOct 4, 2024 · 1. Because, when you choose small K, the classifier's decisions will tend to be affected by local changes more easily. The easiest way to visualize it is for K = 1, which means the decision boundary is affected by every point in the dataset, which means additional complexity drawing them.
