Seminar title: Splitting Methods in Convex Degenerate Optimization with
Applications

Date: Dec 20th, 2023 -12:00, Sala Riunioni Piano C

Abstract: We explore proximal point and forward-backward schemes with
positive semidefinite preconditioners, establishing weak convergence
results and reduced storage requirements. The proposed framework leads us
to new extensions of the Douglas-Rachford Splitting method, and to a new
hybrid method that combines the advantages of proximal- and
conditional-gradient-type schemes. Applications include optimal transport
and regularization parameter learning for total variation denoising.
