A consensus algorithm is the rule a distributed network follows to agree on which new block is added to a blockchain, so every honest node ends up with the same ledger without trusting any single ...

Abstract: In this paper, we propose a dynamical systems perspective of the Expectation-Maximization (EM) algorithm. More precisely, we can analyze the EM algorithm as a nonlinear state-space dynamical ...

Abstract: The Expectation Maximization algorithm is used to infer (a) the parameters of underlying Gaussian distributions of a data set and (b) the probability distributions for each data point that ...

Most people know, or think they know, what a placebo is. A placebo is a “medicine” that isn’t really a medicine yet acts in the same way as a real medication does. Placebos have an effect because the ...
