Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

Sandstedt, Axel January 2023 (has links)
We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. Our main contributions are new algorithms which seek to optimise out unnecessary network communication taking place in the distributed stages of the construction of such estimators using sparse binary tree arithmetics.
