Multilevel procedure for decomposition and mapping graphs

Journal of Physics: Conference Series, 2020
Abstract The paper analyzes the actual problem of architecture-dependent decomposition, allowing efficient planning of running a parallel task in a multiprocessor computer network. The procedure of planning means decomposition of a parallel task in a required number of processors accounting for balance restrictions and mapping of ...

Comparison of Estimation Procedures for Multilevel AR(1) Models [PDF]

Frontiers in Psychology, 2016
To estimate a time series model for multiple individuals, a multilevel model may be used. In this paper we compare two estimation methods for the autocorrelation in Multilevel AR(1) models, namely Maximum Likelihood Estimation (MLE) and Bayesian Markov Chain Monte Carlo.
