Detailed Documentation
This article introduces the k-means outlier removal method, which utilizes clustering mean techniques to identify and eliminate outliers from datasets, thereby improving model prediction accuracy. The implementation involves calculating cluster centroids using k-means algorithm and measuring data point distances from their respective cluster centers to flag statistical outliers. The provided MATLAB code demonstrates practical application through functions like kmeans() for clustering and pdist2() for distance computation, enabling efficient outlier threshold setting and data sanitization. The code includes visualization components using plot() function to display cluster distributions and identified outliers for better analytical insights.
