Researchers have developed MaxSketch, a novel algorithm for robustly estimating the number of distinct elements in data streams, particularly when dealing with high-dimensional and noisy data. Unlike traditional methods that fail with approximate similarities, MaxSketch utilizes random Gaussian projections to achieve significantly improved memory efficiency. This new approach is particularly effective for learned representations and has demonstrated accuracy in experiments with image streams, bridging the gap between classical streaming algorithms and modern representation learning.
