Undecidability of Adjacent Equality for Insertion, Shuffle, and Crossover Language Operations
Charles E. Hughes
We study a family of language operations based on insertion, shuffle, and crossover and investigate the undecidability of adjacent equality together with finite convergence and ass…
Interpretable Machine Learning Methods Applied to Jet Background Subtraction in Heavy Ion Collisions
Tanner Mengel, Patrick Steffanic, Charles Hughes +2
Jet measurements in heavy ion collisions can provide constraints on the properties of the quark gluon plasma, but the kinematic reach is limited by a large, fluctuating background.…
Semi-supervised Drifted Stream Learning with Short Lookback
Weijieying Ren, Pengyang Wang, Xiaolin Li +2
In many scenarios, 1) data streams are generated in real time; 2) labeled data are expensive and only limited labels are available in the beginning; 3) real-world data is not alway…
Reinforced Imitative Graph Learning for Mobile User Profiling
Dongjie Wang, Pengyang Wang, Yanjie Fu +3
Mobile user profiling refers to the efforts of extracting users' characteristics from mobile activities. In order to capture the dynamic varying of user characteristics for generat…
Reinforced Imitative Graph Representation Learning for Mobile User Profiling: An Adversarial Training Perspective
Dongjie Wang, Pengyang Wang, Kunpeng Liu +3
In this paper, we study the problem of mobile user profiling, which is a critical component for quantifying users' characteristics in the human mobility modeling pipeline. Human mo…
Facial Expression Representation Learning by Synthesizing Expression Images
Kamran Ali, Charles E. Hughes
Representations used for Facial Expression Recognition (FER) usually contain expression information along with identity features. In this paper, we propose a novel Disentangled Exp…
All-In-One: Facial Expression Transfer, Editing and Recognition Using A Single Network
Kamran Ali, Charles E. Hughes
In this paper, we present a unified architecture known as Transfer-Editing and Recognition Generative Adversarial Network (TER-GAN) which can be used: 1. to transfer facial express…
Facial Expression Recognition Using Human to Animated-Character Expression Translation
Kamran Ali, Ilkin Isler, Charles Hughes
Facial expression recognition is a challenging task due to two major problems: the presence of inter-subject variations in facial expression recognition dataset and impure expressi…
Facial Expression Recognition Using Disentangled Adversarial Learning
Kamran Ali, Charles E. Hughes
The representation used for Facial Expression Recognition (FER) usually contain expression information along with other variations such as identity and illumination. In this paper,…
A Distributed Augmented Reality System for Medical Training and Simulation
Felix G. Hamza-Lup, Jannick P. Rolland, Charles Hughes
Augmented Reality (AR) systems describe the class of systems that use computers to overlay virtual information on the real world. AR environments allow the development of promising…
Sensors in Distributed Mixed Reality Environments
Felix G. Hamza-Lup, Charles Hughes, Jannick P. Rolland
With the advances in sensors and computer networks an increased number of Mixed Reality (MR) applications require large amounts of information from the real world. Such information…
Hand2Face: Automatic Synthesis and Recognition of Hand Over Face Occlusions
Behnaz Nojavanasghari, Charles. E. Hughes, Tadas Baltrusaitis +1
A person's face discloses important information about their affective state. Although there has been extensive research on recognition of facial expressions, the performance of exi…
