Sparser johnson-lindenstrauss transforms

DM Kane, J Nelson - Journal of the ACM (JACM), 2014 - dl.acm.org
We give two different and simple constructions for dimensionality reduction in ℓ 2 via linear
map**s that are sparse: only an O (ε)-fraction of entries in each column of our embedding …

Improved analysis of the subsampled randomized Hadamard transform

JA Tropp - Advances in Adaptive Data Analysis, 2011 - World Scientific
This paper presents an improved analysis of a structured dimension-reduction map called
the subsampled randomized Hadamard transform. This argument demonstrates that the …

Performance of Johnson-Lindenstrauss transform for k-means and k-medians clustering

K Makarychev, Y Makarychev… - Proceedings of the 51st …, 2019 - dl.acm.org
Consider an instance of Euclidean k-means or k-medians clustering. We show that the cost
of the optimal solution is preserved up to a factor of (1+ ε) under a projection onto a random …

Approximate nearest neighbor search in high dimensions
