Multi-Scale Multi-Kernel Gaussian Process Latent Variable Model [PDF]
Jisuanji gongcheng, 2021 As an unsupervised Bayesian non-parameter dimension reduction model,the Gaussian Process Latent Variable Model(GPLVM) fails to efficiently utilize semantic label information of data.Moreover,it just assumes that the features of all observed variables are

Latent Variable Analysis and Signal Separation [PDF]
, 2022 We assume a second-order source separation model where the observed multivariate time series is a linear mixture of latent, temporally uncorrelated time series with some components pure white noise.

Econometrics, 2019 It is customary to assume that an indicator of a latent variable is driven by the latent variable and some random noise. In contrast, a background indicator is also systematically influenced by variables outside the structural model of interest ...

A dynamic latent variable model for source separation [PDF]
, 2018 We propose a novel latent variable model for learning latent bases for time-varying non-negative data. Our model uses a mixture multinomial as the likelihood function and proposes a Dirichlet distribution with dynamic parameters as a prior, which we call

Multiscale Latent Variable Regression
International Journal of Chemical Engineering, 2010 Multiscale wavelet-based representation of data has been shown to be a powerful tool in feature extraction from practical process data. In this paper, this characteristic of multiscale representation is utilized to improve the prediction accuracy of some
