Knn greedy coreset
WebBayesian Coreset Construction via Greedy Iterative Geodesic Ascent Figure 1. (Left) Gaussian inference for an unknown mean, showing data (black points and likelihood densities), exact posterior (blue), and optimal coreset posterior approximations of size 1 from solving the original coreset construction problem Eq. (3) (red) and the modified WebSep 3, 2010 · The problem of maximizing a concave function f(x) in the unit simplex Δ can be solved approximately by a simple greedy algorithm. For given k, the algorithm can find a point x (k) on a k-dimensional face of Δ, such that f(x (k) ≥ f(x *) − O(1/k).Here f(x *) is the maximum value of f in Δ, and the constant factor depends on f.This algorithm and …

When the coreset reaches a certain size, these “nearly flat” directions are all removed, and u-turns happen more frequently. Thus we expect the computation time as a func-tion of coreset size to initially increase smoothly, then drop quickly, followed by a final smooth increase, in agreement with Fig.7b. B. Technical Results and ...

Webcoreset) of the points, such that one can perform the desired computation on the coreset. As a concrete example, consider the problem of computing the diameter of a point set. Here it is clear that, in the worst case, classical sampling techniques like "-approximation and "-net would fail to compute
