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

Why K-Means Fails on Non-Convex Clusters and Alternatives

by

K-means clustering stands as one of the most popular unsupervised learning algorithms, beloved for its simplicity, speed, and interpretability. From customer segmentation to image compression, k-means has become the default choice when practitioners need to partition data into groups. Yet beneath this widespread adoption lies a fundamental limitation that many overlook until it causes their … Read more

Anomaly Detection Using K-Means Clustering in Python

by

Detecting anomalies—unusual patterns that don’t conform to expected behavior—is crucial across countless domains. Fraudulent transactions hide among millions of legitimate purchases, equipment failures announce themselves through abnormal sensor readings, network intrusions masquerade as normal traffic, and manufacturing defects appear as outliers in quality metrics. While many sophisticated anomaly detection algorithms exist, k-means clustering offers an … Read more

K-Means Clustering for Customer Segmentation

by

Understanding your customers is the cornerstone of effective marketing, product development, and business strategy. Yet when your customer base numbers in the thousands or millions, identifying meaningful patterns becomes overwhelming. How do you discover which customers share similar behaviors, preferences, or value to your business? This is where k-means clustering transforms raw customer data into … Read more
