Dynamic latent variable
WebDynamic network models with latent variables 107 tic blockmodels (SBM) assume that the nodes of the network are partitioned into several unobserved (latent) classes (or blocks). The framework is first in-troduced byHollandetal.[37]whichfocuses onthecaseofa priori specified blocks, where the membership of nodes are known or assumed, and the goal WebIn this paper, a multivariate statistical model based on the multiblock kernel dynamic latent variable (MBKDLV) is proposed to monitor large-scale industrial processes. It divides …

WebAbstract: Dynamic-inner canonical correlation analysis (DiCCA) extracts dynamic latent variables from high-dimensional time series data with a descending order of predictability in terms of R 2.The reduced dimensional latent variables with rank-ordered predictability capture the dynamic features in the data, leading to easy interpretation and visualization. WebJul 27, 2024 · A concurrent locality-preserving dynamic latent variable (CLDLV) method is proposed to extract the correlation between process variables and quality variables for quality-related dynamic process monitoring. Given that dynamic process data can easily be contaminated by noise and outliers and conventional dynamic latent variable models …
