Optimal Matrix Sketching over Sliding Windows
Summary: Presents DS-FD, a matrix-sketching algorithm that attains the optimal O(d/ε) space bound for sliding-window streams (row-normalized, sequence-based), preserving FrequentDirections-style covariance guarantees. Proves matching upper/lower bounds for time-based and unnormalized windows, resolving the open question on optimal sliding-window space and validating performance empirically.
