Deep Learning-Derived Optimal Aviation Strategies to Control Pandemics

no code implementations12 Oct 2022 Syed Rizvi, Akash Awasthi, Maria J. Peláez, Zhihui Wang, Vittorio Cristini, Hien Van Nguyen, Prashant Dogra

The COVID-19 pandemic has affected countries across the world, demanding drastic public health policies to mitigate the spread of infection, leading to economic crisis as a collateral damage.

PICASO: Permutation-Invariant Cascaded Attentional Set Operator

1 code implementation17 Jul 2021 Samira Zare, Hien Van Nguyen

This is in part due to the increasing number of important tasks such as meta-learning, clustering, and anomaly detection that are defined on set inputs.

Trans-Caps: Transformer Capsule Networks with Self-attention Routing

no code implementations1 Jan 2021 Aryan Mobiny, Pietro Antonio Cicalese, Hien Van Nguyen

Capsule Networks (CapsNets) have shown to be a promising alternative to Convolutional Neural Networks (CNNs) in many computer vision tasks, due to their ability to encode object viewpoint variations.

Kidney Level Lupus Nephritis Classification using Uncertainty Guided Bayesian Convolutional Neural Networks

1 code implementation18 Nov 2020 Pietro A. Cicalese, Aryan Mobiny, Zahed Shahmoradi, Xiongfeng Yi, Chandra Mohan, Hien Van Nguyen

The kidney biopsy based diagnosis of Lupus Nephritis (LN) is characterized by low inter-observer agreement, with misdiagnosis being associated with increased patient morbidity and mortality.

StyPath: Style-Transfer Data Augmentation For Robust Histology Image Classification

1 code implementation9 Jul 2020 Pietro Antonio Cicalese, Aryan Mobiny, Pengyu Yuan, Jan Becker, Chandra Mohan, Hien Van Nguyen

We also generated Grad-CAM representations of the results which were assessed by an experienced nephropathologist; we used this qualitative analysis to elucidate on the assumptions being made by each model.
