Statistical distances between densities of an exponential family often admit closed-form formula (Sharma-Mittal/Renyi/Tsallis/Shannon relative entropies/divergences). Optimal transport distances vs information-geometric divergences. Projective divergences tinyurl.com/y67hmoxs

Hot off the press: We have developed a self-supervised learning method that is much better for pre-training than ImageNet--reduces labeling needs by an order of magnitude for medical imaging applications: @stanfordAIMI @Radiology_AI

👋 Excited to share our latest work "Contrastive Learning of Medical Visual Representations from Paired Images and Text". We propose a contrastive framework for learning visual representations of medical images from paired textual data. arXiv: arxiv.org/abs/2010.00747 👇 (1/7)

RigL is a new algorithm for training sparse neural networks. Instead of pruning a pre-existing dense network, it dynamically builds one during training without sacrificing accuracy relative to traditional approaches. Learn how it’s done at goo.gle/2ZJryiU

Natural gradient uses *steepest descent* but may leave the manifold. Riemannian gradient always stay on the manifold (but exponential map difficult to calculate). Natural gradient= approximation of the Riemannian gradient using a simple rectraction. tinyurl.com/y43bu2zd
