While successful in clustering multiple types of high-dimensional data, subspace clustering algorithms do not scale well as the number of data increases. The present paper puts forth a novel randomized subspace clustering algorithm for high-dimensional data based on a random sketching and validation approach. Utilizing a data-driven random sketching technique to estimate the underlying probability...
As the number and dimensionality of data increases, development of new efficient processing tools has become a necessity. The present paper introduces a novel dimensionality reduction approach for fast and efficient clustering of high-dimensional data. The new methods extend random sampling and consensus (RANSAC) arguments, originally developed for robust regression tasks in computer vision, to the...
