CCS-GAN: COVID-19 CT-scan classification with very few positive training images

no code implementations1 Oct 2021 Sumeet Menon, Jayalakshmi Mangalagiri, Josh Galita, Michael Morris, Babak Saboury, Yaacov Yesha, Yelena Yesha, Phuong Nguyen, Aryya Gangopadhyay, David Chapman

CCS-GAN achieves high accuracy with few positive images and thereby greatly reduces the barrier of acquiring large training volumes in order to train a diagnostic classifier for COVID-19.

Estimating the Uncertainty of Neural Network Forecasts for Influenza Prevalence Using Web Search Activity

no code implementations26 May 2021 Michael Morris, Peter Hayes, Ingemar J. Cox, Vasileios Lampos

In this paper, we demonstrate how Bayesian Neural Networks (BNNs) can be used to both provide a forecast and a corresponding uncertainty without significant loss in forecasting accuracy compared to traditional NNs.

Toward Generating Synthetic CT Volumes using a 3D-Conditional Generative Adversarial Network

no code implementations2 Apr 2021 Jayalakshmi Mangalagiri, David Chapman, Aryya Gangopadhyay, Yaacov Yesha, Joshua Galita, Sumeet Menon, Yelena Yesha, Babak Saboury, Michael Morris, Phuong Nguyen

We present a novel conditional Generative Adversarial Network (cGAN) architecture that is capable of generating 3D Computed Tomography scans in voxels from noisy and/or pixelated approximations and with the potential to generate full synthetic 3D scan volumes.

Deep Expectation-Maximization for Semi-Supervised Lung Cancer Screening

no code implementations2 Oct 2020 Sumeet Menon, David Chapman, Phuong Nguyen, Yelena Yesha, Michael Morris, Babak Saboury

We present a semi-supervised algorithm for lung cancer screening in which a 3D Convolutional Neural Network (CNN) is trained using the Expectation-Maximization (EM) meta-algorithm.
