Web2024. Computer Science. We consider the problem of distributed mean estimation (DME), in which n machines are each given a local d-dimensional vector xv ∈ R, and must cooperate to estimate the mean of their inputs μ = 1 n ∑n v=1 xv, while minimizing total communication cost. DME is a fundamental construct in distributed machine learning ... WebMay 16, 2024 · The sum of poisson distributed random variables is again Poisson distributed. The mean of the resulting distribution for \(K\) is \(N\mu\): \[K \sim \text{Pois}(N\mu)\] We will get back to estimating the mean from the complete set of results, but first let’s look at estimating it from the sum of the results. Estimating the …
