On Robust Probabilistic Principal Component Analysis using Multivariate $t$-Distributions

no code implementations21 Oct 2020 Yiping Guo, Howard D. Bondell

Probabilistic principal component analysis (PPCA) is a probabilistic reformulation of principal component analysis (PCA), under the framework of a Gaussian latent variable model.

Conditional Density Estimation via Weighted Logistic Regressions

no code implementations21 Oct 2020 Yiping Guo, Howard D. Bondell

Compared to the conditional mean as a simple point estimator, the conditional density function is more informative to describe the distributions with multi-modality, asymmetry or heteroskedasticity.

Nonparametric Conditional Density Estimation In A Deep Learning Framework For Short-Term Forecasting

no code implementations17 Aug 2020 David B. Huberman, Brian J. Reich, Howard D. Bondell

We propose a technique that simultaneously estimates the entire conditional distribution and flexibly allows for machine learning techniques to be incorporated.

Bayesian Regression Using a Prior on the Model Fit: The R2-D2 Shrinkage Prior

1 code implementation31 Aug 2016 Yan Dora Zhang, Brian P. Naughton, Howard D. Bondell, Brian J. Reich

The proposed method compares favourably to previous approaches in terms of both concentration around the origin and tail behavior, which leads to improved performance both in posterior contraction and in empirical performance.
