Cluster-Adaptive Feature Extraction and its Theoretical Foundation with Minkowski Weighted k-Means
Researchers have developed a new method called Cluster-Adaptive Feature Extraction (CAFE) that enhances unsupervised feature extraction. CAFE utilizes Minkowski weighted k-means ($mwk$-means) to adaptively weight features based on their dispersion within clusters. This approach theoretically demonstrates how feature weights can suppress noisy features and amplify informative ones, leading to improved results in experiments. AI
