I am a Machine Learning PhD student at Center for Visual Computing at CentraleSupélec, Université Paris-Saclay, supervised by Matthew B. Blaschko. I am also a member of INRIA Galen team.

My major research interests are structured output prediction, non-modular loss functions, surrogate functions etc. I am also interested in the application of image classification, image segmentation, and medical images analysis.

News:


I've successfully defended my PhD thesis!
I gave an oral presentation at BMVC2016!
I presented our work at BeneLearn2016!
I was visiting KU Leuven, VISICS group this summer.
I gave an oral presentation at AISTATS2016
An extended version of our ICML2015 paper is online.
I gave an oral presentation at ICML2015 on learning submodular losses with the Lovasz Hinge, at Lille France.
I gave an oral presentation at NIPS 2014 Representation and Learning Methods for Complex Outputs Workshop, at Montreal Canada.
