K-Means vs K-Nearest Neighbor: Two Fundamentally Different Algorithms

by

Despite their confusingly similar names and shared use of the letter “k,” k-means and k-nearest neighbor (KNN) represent fundamentally different machine learning paradigms that solve completely different problems through entirely distinct mechanisms. K-means is an unsupervised clustering algorithm that discovers natural groupings in unlabeled data by iteratively assigning points to cluster centers and updating those … Read more

KNN in Machine Learning Explained (with Python Example)

by

K-Nearest Neighbors (KNN) is one of the simplest yet most effective machine learning algorithms. Unlike many complex models that require extensive training, KNN operates on an intuitive principle: similar things exist close together. If you’re trying to classify a new data point, why not look at what its nearest neighbors are? This beautifully simple idea … Read more
