Event Representation with Sequential, Semi-Supervised Discrete Variables
Mehdi Rezaee, Francis Ferraro
Within the context of event modeling and understanding, we propose a new method for neural sequence modeling that takes partially-observed sequences of discrete, external knowledge…
Electronic Thermal Transport Measurement in Low-Dimensional Materials with Graphene Nonlocal Noise Thermometry
Jonah Waissman, Laurel E. Anderson, Artem V. Talanov +11
In low-dimensional systems, the combination of reduced dimensionality, strong interactions, and topology has led to a growing number of many-body quantum phenomena. Thermal transpo…
A Discrete Variational Recurrent Topic Model without the Reparametrization Trick
Mehdi Rezaee, Francis Ferraro
We show how to learn a neural topic model with discrete random variables---one that explicitly models each word's assigned topic---using neural variational inference that does not…
Heterointerface effects in the electro-intercalation of van der Waals heterostructures
D. Kwabena Bediako, Mehdi Rezaee, Hyobin Yoo +7
Molecular-scale manipulation of electronic/ionic charge accumulation in materials is a preeminent challenge, particularly in electrochemical energy storage. Layered van der Waals (…
Semantically-informed Hierarchical Event Modeling
Shubhashis Roy Dipta, Mehdi Rezaee, Francis Ferraro
Prior work has shown that coupling sequential latent variable models with semantic ontological knowledge can improve the representational capabilities of event modeling approaches.…
RevUp: Revise and Update Information Bottleneck for Event Representation
Mehdi Rezaee, Francis Ferraro
The existence of external (``side'') semantic knowledge has been shown to result in more expressive computational event models. To enable the use of side information that may be no…
A scalable platform for nanometer-scale quantum confinement
Christina M. Spaegele, Mehdi Rezaee, Thomas Werkmeister +8
Overcoming the limitations of current nanofabrication techniques to achieve nanoscale feature sizes is essential for achieving new regimes of light-matter interactions at extreme f…
Engineering Phonon Polaritons in van der Waals Heterostructures to Enhance In-Plane Optical Anisotropy
Kundan Chaudhary, Michele Tamagnone, Mehdi Rezaee +4
Van der Waals heterostructures assembled from layers of 2D materials have attracted considerable interest due to their novel optical and electrical properties. Here we report a sca…
Discriminative and Generative Transformer-based Models For Situation Entity Classification
Mehdi Rezaee, Kasra Darvish, Gaoussou Youssouf Kebe +1
We re-examine the situation entity (SE) classification task with varying amounts of available training data. We exploit a Transformer-based variational autoencoder to encode senten…
A Survey on Compressive Sensing: Classical Results and Recent Advancements
Ahmad Mousavi, Mehdi Rezaee, Ramin Ayanzadeh
Recovering sparse signals from linear measurements has demonstrated outstanding utility in a vast variety of real-world applications. Compressive sensing is the topic that studies…
