Twitter Cortex Vx, London, UK

September, 2016

In July, I have joined Twitter Cortex as Computer Vision Researcher. We employ and advance machine learning approaches to improve the user's visual experience (Vx). Very recently, we have published an arXiv paper on “Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network” that you can find here: [pdf]

MICCAI and NeuroImage paper accepted

July, 2016

Our work on the “Differential Dementia Diagnosis on Incomplete Data with Latent Trees” was accepted for presentation at MICCAI 2016 and our work on “Instantiated mixed effects modeling of Alzheimer's disease markers” was accepted in NeuroImage. The papers are available here:
[MICCAI - pdf] [NeuroImage - doi]

Publications update

May, 2016

In a recent article we present “A Robust Similarity Measure for Volumetric Image Registration with Outliers” (Snape et al., Image and Vision Computing, [doi] [pdf])

Two articles accepted on the modelling and prediction of AD progression

April, 2016

In one article we focus on “Learning biomarker models for progression estimation of Alzheimer's disease” (Schmidt-Richberg et al., PLoSONE, [doi]).

We further propose “A Novel Grading Biomarker for the Prediction of Conversion from Mild Cognitive Impairment to Alzheimer's Disease” (Tong et al., IEEE Transactions on Biomedical Engineering, [doi]).

Enjoy reading.
