WebBy incorporating the framework of the Bayesian inference, a new tensor decomposition model on the subtle matrix unfolding outer product is established for both tensor completion and robust principal component analysis problems, including hyperspectral image completion and denoising, traffic data imputation, and video background subtraction.

WebBayesian inference relies on transparent modeling assumptions to make conclusions about a dataset. Those assumptions are often (or always) wrong, which can affect the downstream conclusions we make. To combat this issue, many approaches have been proposed to make Bayesian inference “robust” to false assumptions.

WebWe use the concept of coarsened posteriors to provide robust Bayesian inference via coarsening in order to robustify posteriors arising from stochastic frontier models. These posteriors arise from tempered versions of the likelihood when at most a pre-speciﬁed amount of data is used, and are robust to changes in the model.

WebMar 1, 2024 · Here we focus on the robustness approach based on the influence function and on the derivation of robust posterior distributions from robust M -estimating functions, i.e. estimating equations with bounded influence function (see, e.g., Huber and Ronchetti, 2009, Chap. 3). In particular, we propose an approach based on Approximate Bayesian ... WebMar 1, 2024 · Even more severe, small insignificant partial correlations due to noise can dramatically change the clustering result when evaluating for example with the Bayesian information criteria (BIC). In this work, we try to address this issue by proposing a Bayesian model that accounts for negligible small, but not necessarily zero, partial correlations.
