Stratified Graphical Models - Context-Specific Independence in Graphical Models

open access: yesBayesian Analysis, 2013
Theory of graphical models has matured over more than three decades to provide the backbone for several classes of models that are used in a myriad of applications such as genetic mapping of diseases, credit risk evaluation, reliability and computer ...

Graphical Markov models: overview [PDF]

open access: yes, 2015
We describe how graphical Markov models started to emerge in the last 40 years, based on three essential concepts that had been developed independently more than a century ago.

Conditional Functional Graphical Models. [PDF]

open access: yesJ Am Stat Assoc, 2023
Graphical modeling of multivariate functional data is becoming increasingly important in a wide variety of applications. The changes of graph structure can often be attributed to external variables, such as the diagnosis status or time, the latter of which gives rise to the problem of dynamic graphical modeling.

PU-GAT: Point cloud upsampling with graph attention network

open access: yesGraphical Models, 2023
Point cloud upsampling has been extensively studied, however, the existing approaches suffer from the losing of structural information due to neglect of spatial dependencies between points.

Unsupervised learning of style-aware facial animation from real acting performances

open access: yesGraphical Models, 2023
This paper presents a novel approach for text/speech-driven animation of a photo-realistic head model based on blend-shape geometry, dynamic textures, and neural rendering.

Fast progressive polygonal approximations for online strokes

open access: yesGraphical Models, 2023
This paper presents a fast and progressive polygonal approximation algorithm for online strokes. A stroke is defined as a sequence of points between a pen-down and a pen-up. The proposed method generates polygonal approximations progressively as the user

Joint data and feature augmentation for self-supervised representation learning on point clouds

open access: yesGraphical Models, 2023
To deal with the exhausting annotations, self-supervised representation learning from unlabeled point clouds has drawn much attention, especially centered on augmentation-based contrastive methods.

RFMNet: Robust Deep Functional Maps for unsupervised non-rigid shape correspondence

open access: yesGraphical Models, 2023
In traditional deep functional maps for non-rigid shape correspondence, estimating a functional map including high-frequency information requires enough linearly independent features via the least square method, which is prone to be violated in practice,

Unified shape and appearance reconstruction with joint camera parameter refinement

open access: yesGraphical Models, 2023
In this paper, we present an inverse rendering method for the simple reconstruction of shape and appearance of real-world objects from only roughly calibrated RGB images captured under collocated point light illumination.

High-fidelity point cloud completion with low-resolution recovery and noise-aware upsampling

open access: yesGraphical Models, 2023
Completing an unordered partial point cloud is a challenging task. Existing approaches that rely on decoding a latent feature to recover the complete shape, often lead to the completed point cloud being over-smoothing, losing details, and noisy.
