Subspace clustering without knowing the number of clusters: A parameter free approach

Vishnu Menon,
Gokularam M,
Sheetal Kalyani

Abstract: Subspace clustering, the task of clustering high dimensional data when the data points come from a union of subspaces is one of the fundamental tasks in unsupervised machine learning. Most of the existing algorithms for this task involves supplying prior information in form of a parameter, like the number of clusters, to the algorithm. In this work, a parameter free method for subspace clustering is proposed, where the data points are clustered on the basis of the difference in statistical distribution of the … Show more

“…However, a recurring problem with BOMP, SOMP etc. (similar to many other signal processing problems like [21], [22]) is the requirement of a priori knowledge of signal sparsity (k 0 or k b ) or ambient noise variance σ 2 . Both sparsity and noise variance are rarely known a priori in practical applications.…”
