Perplexity-free Parametric t-SNE

1 code implementation3 Oct 2020 Francesco Crecchi, Cyril de Bodt, Michel Verleysen, John A. Lee, Davide Bacciu

The t-distributed Stochastic Neighbor Embedding (t-SNE) algorithm is a ubiquitously employed dimensionality reduction (DR) method.

Deep Learning to Detect Bacterial Colonies for the Production of Vaccines

no code implementations2 Sep 2020 Thomas Beznik, Paul Smyth, Gaël de Lannoy, John A. Lee

During the development of vaccines, bacterial colony forming units (CFUs) are counted in order to quantify the yield in the fermentation process.

Knowing what you know in brain segmentation using Bayesian deep neural networks

1 code implementation3 Dec 2018 Patrick McClure, Nao Rho, John A. Lee, Jakub R. Kaczmarzyk, Charles Zheng, Satrajit S. Ghosh, Dylan Nielson, Adam G. Thomas, Peter Bandettini, Francisco Pereira

In this paper, we describe a Bayesian deep neural network (DNN) for predicting FreeSurfer segmentations of structural MRI volumes, in minutes rather than hours.

Brain Segmentation Variational Inference

Capturing Variabilities from Computed Tomography Images with Generative Adversarial Networks

no code implementations29 May 2018 Umair Javaid, John A. Lee

The generated CT images have good global and local features of a real CT image and can be used to augment the training datasets for effective learning.

Computed Tomography (CT) Data Augmentation

Distributed Weight Consolidation: A Brain Segmentation Case Study

no code implementations NeurIPS 2018 Patrick McClure, Charles Y. Zheng, Jakub R. Kaczmarzyk, John A. Lee, Satrajit S. Ghosh, Dylan Nielson, Peter Bandettini, Francisco Pereira

Collecting the large datasets needed to train deep neural networks can be very difficult, particularly for the many applications for which sharing and pooling data is complicated by practical, ethical, or legal concerns.

Blind Deconvolution of PET Images using Anatomical Priors

no code implementations5 Aug 2016 Stéphanie Guérit, Adriana González, Anne Bol, John A. Lee, Laurent Jacques

Images from positron emission tomography (PET) provide metabolic information about the human body.

Post-Reconstruction Deconvolution of PET Images by Total Generalized Variation Regularization

no code implementations16 Jun 2015 Stéphanie Guérit, Laurent Jacques, Benoît Macq, John A. Lee

Improving the quality of positron emission tomography (PET) images, affected by low resolution and high level of noise, is a challenging task in nuclear medicine and radiotherapy.
