Geometric Understanding of Deep Learning

no code implementations26 May 2018 Na Lei, Zhongxuan Luo, Shing-Tung Yau, David Xianfeng Gu

In this work, we give a geometric view to understand deep learning: we show that the fundamental principle attributing to the success is the manifold structure in data, namely natural high dimensional data concentrates close to a low-dimensional manifold, deep learning learns the manifold and the probability distribution on it.

A Geometric View of Optimal Transportation and Generative Model

no code implementations16 Oct 2017 Na Lei, Kehua Su, Li Cui, Shing-Tung Yau, David Xianfeng Gu

In this work, we show the intrinsic relations between optimal transportation and convex geometry, especially the variational approach to solve Alexandrov problem: constructing a convex polytope with prescribed face normals and volumes.
