Applying K-Means Clustering for Image Compression and Student Grouping

Image Compression with K-Means K-Means clustering can be effective used for image compression. The core idea is to reduce the number of colors in an image. Instead of storing the exact RGB value for every pixel, we can group similar colors into clusters. Each pixel is then represented by the color of its cluster's centroid, significantly reduci ...

Understanding K-Means Clustering: Algorithm, Implementation, and Best Practices

Overview K-Means is one of the most widely used clustering algorithms in machine learning and data analysis. It fals under the category of unsupervised learning algorithms, meaning it discovers natural groupings in data without pre-defined labels. The algorithm partitions a dataset into K distinct clusters based on feature similarity, where sim ...
