摘要:

Compressive sensing and deep learning are the two hottest topic in the past two decades. In this technical sharing, we will cover the basics of compressive sensing and discuss their relationships with the deep learning techniques. Specifically, the following topics will be discussed

  

-- Motivation: High-dimensional data analysis with low-dimensional model

-- Compressive Sensing: \ell_0 norm, its relaxation \ell_1 norm and the geometry

-- Deep Learning: (Guaranteed) network compression

-- Compressive Sensing: A simple algorithm for \ell_1 norm minimization

-- Deep Learning: Deep Unrolling

-- Compressive Sensing: ODE and optimal algorithm

-- Deep Learning: Neural ODE
