LoomSC framework boosts deep subspace clustering scalability and accuracy

Researchers have developed LoomSC, a novel framework for deep subspace clustering that significantly improves scalability and accuracy. By employing projector factorization and exact spectral reduction, LoomSC avoids the computational bottlenecks of dense self-expression matrices and full-affinity spectral clustering. This approach allows for linear time and memory complexity with respect to the number of samples, enabling it to handle datasets with up to 500,000 samples while maintaining high accuracy. In evaluations across five image-clustering benchmarks, LoomSC outperformed nine state-of-the-art baselines, achieving first or second rank in all comparisons and showing a mean accuracy improvement of 6.66 percentage points.
