Feb 25, 2025 · Clustering is an unsupervised machine learning technique designed to group unlabeled examples based on their similarity to each other. (If the examples are labeled, this kind of grouping is called classification.) Consider a hypothetical patient study designed to evaluate a new treatment protocol.

Feb 25, 2025 · Centroid-based clustering algorithms are efficient but sensitive to initial conditions and outliers. Of these, k-means is the most widely used. It requires users to define the number of centroids, k, and works well with clusters of roughly equal size. Figure 1: Example of centroid-based clustering. Density-based clustering

Feb 25, 2025 · Describe clustering use cases in machine learning applications. Choose the appropriate similarity measure for an analysis. Cluster data with the k-means algorithm.

Feb 25, 2025 · For example, agglomerative or divisive hierarchical clustering algorithms look at all pairs of points and have complexities of \(O(n^2 log(n))\) and \(O(n^2)\), respectively. This course focuses on k-means because it scales as \(O(nk)\), where \(k\) is …

Feb 25, 2025 · To cluster your data, you'll follow these steps: Prepare data. Create similarity metric. Run clustering algorithm. Interpret results and adjust your clustering. This page briefly introduces the steps. We'll go into depth in subsequent sections. Prepare data

Le clustering basé sur le centroïde organise les données en clusters non hiérarchiques. Les algorithmes de clustering basés sur le centroïde sont efficaces, mais sensibles aux conditions initiales et aux valeurs aberrantes.

Clustering-Algorithmus ausführen. Ein Clustering-Algorithmus verwendet den Ähnlichkeitsmesswert, um Daten zu clustern. In diesem Kurs wird k-Means verwendet. Ergebnisse interpretieren und anpassen
