Expert: high-dimensional clustering
High-dimensional clustering has become a cornerstone of advanced data analysis in 2025, bridging unsupervised learning, representation learning, and manifold geometry. This post explores the theory and practice of clustering in high-dimensional spaces — from the curse of dimensionality to cutting-edge techniques like subspace clustering, contrastive learning embeddings, and scalable approximate algorithms used in production by…
