Notes on optimal transport

This summer I stumbled upon the optimal transportation problem, an optimization paradigm where the goal is to transform one probability distribution into another with a minimal cost. It is so simple to understand, yet it has a mind-boggling number of applications in probability, computer vision, machine learning, computational fluid dynamics and computational biology. I recently gave a seminar on this topic and this post is an overview on the topic. Slides can be found on my SlideShare and some implementations can are shown in a Jupyter notebook in my Github repo. Enjoy!

Seven things I learned during the PhD Cup media school

Whether you like it or not, a large part of a scientist job is about communicating. You have to pitch your ideas to collaborators, outline your plans to get grants, educate your students and report your findings to the scientific community. It is hence a good investment to spend a bit of your precious time honing your soft skills.
