Complexity Theoretic Lower Bounds for Sparse Principal Component Detection

Published on Aug 09, 20136388 Views

In the context of sparse principal component detection, we bring evidence towards the existence of a statistical price to pay for computational efficiency. We measure the performance of a test by the
