Variational Sampling of Temporal Trajectories

Jurijs Nazarovs, Zhichun Huang, Xingjian Zhen +3

A deterministic temporal process can be determined by its trajectory, an element in the product space of (a) initial condition and (b) transition function $f:…

On the Versatile Uses of Partial Distance Correlation in Deep Learning

Xingjian Zhen, Zihang Meng, Rudrasis Chakraborty +1

Comparing the functional behavior of neural network models, whether it is a single network over time or two (or more networks) during or post-training, is an essential step in unde…

A First Look: Towards Explainable TextVQA Models via Visual and Textual Explanations

Varun Nagaraj Rao, Xingjian Zhen, Karen Hovsepian +1

Explainable deep learning models are advantageous in many situations. Prior work mostly provide unimodal explanations through post-hoc approaches not part of the original system de…

Simpler Certified Radius Maximization by Propagating Covariances

Xingjian Zhen, Rudrasis Chakraborty, Vikas Singh

One strategy for adversarially training a robust model is to maximize its certified radius -- the neighborhood around a given training sample for which the model's prediction remai…

Flow-based Generative Models for Learning Manifold to Manifold Mappings

Xingjian Zhen, Rudrasis Chakraborty, Liu Yang +1

Many measurements or observations in computer vision and machine learning manifest as non-Euclidean data. While recent proposals (like spherical CNN) have extended a number of deep…

CPR-GCN: Conditional Partial-Residual Graph Convolutional Network in Automated Anatomical Labeling of Coronary Arteries

Han Yang, Xingjian Zhen, Ying Chi +2

Automated anatomical labeling plays a vital role in coronary artery disease diagnosing procedure. The main challenge in this problem is the large individual variability inherited i…

Dilated Convolutional Neural Networks for Sequential Manifold-valued Data

Xingjian Zhen, Rudrasis Chakraborty, Nicholas Vogt +2

Efforts are underway to study ways via which the power of deep neural networks can be extended to non-standard data types such as structured data (e.g., graphs) or manifold-valued…

A Statistical Recurrent Model on the Manifold of Symmetric Positive Definite Matrices

Rudrasis Chakraborty, Chun-Hao Yang, Xingjian Zhen +5

In a number of disciplines, the data (e.g., graphs, manifolds) to be analyzed are non-Euclidean in nature. Geometric deep learning corresponds to techniques that generalize deep ne…
