Summary

Dimension Reduction involves mapping points from a high-dimensional space to a lower-dimensional space with minimal distortion. The Johnson-Lindenstrauss Theorem states that for any set of n points in ℝd, there exists a mapping ϕ to ℝk with k = O(ϵ−2 log n) such that ∀x, y: (1 −ϵ)∥x −y∥2 ≤ ∥ϕ(x) −ϕ(y)∥2 ≤ (1 + ϵ)∥x −y∥2, allowing embedding in O(log n) dimension with constant distortion.
