- Sparsity and compressive sensing have had a tremendous impact in science, technology, medicine, imaging, machine learning and now, in solving multiscale problems in applied partial differential equations, developing sparse bases for Elliptic eigenspaces and connections with viscosity solutions to Hamilton-Jacobi equations. $ℓ_1$ and related optimization solvers are a key tool in this area. The special nature of this functional allows for very fast solvers: $ℓ_1$ actually forgives and forgets errors in Bregman iterative methods.
I will describe simple, fast algorithms and new applications ranging from image processing, machine learning to sparse dynamics for PDE.
