WebFeb 13, 2024 · The K-Nearest Neighbor algorithm in this tutorial will focus on classification problems, though many of the principles will work for regression as well. The tutorial assumes no prior knowledge of the K-Nearest Neighbor (or KNN) algorithm. By the end of this tutorial, you’ll have learned: How the algorithm works to predict classes of data WebKNN works on a principle assuming every data point falling in near to each other is falling in the same class. In other words, it classifies a new data point based on similarity. Let us understand the concept by taking an example: Example: Two classes green and red and a …
WebJul 28, 2024 · K-Nearest Neighbors, also known as KNN, is probably one of the most intuitive algorithms there is, and it works for both classification and regression tasks. Since it is so easy to understand, it is a good baseline against which to compare other algorithms, specially these days, when interpretability is becoming more and more important. Intuition
