The 2nd workshop on Operator Splitting Methods in Data Analysis brings together experts from nonlinear analysis, optimization, data analysis, and statistics to advance the field of operator splitting methods and its application to statistics and data analysis.

Specific topics include:
(i) general forms of equilibria that are captured by monotone inclusions,
(ii) nonconvex/nonmonotone splitting methods
(iii) scaling up of splitting strategies as the numbers of observations and features grow
(iv) robustness of splitting methods under perturbations and modeling errors
(v) New and nonstandard variational formulations for data analysis problems
(vi) Applications of splitting methods in data analysis and statistics

A unique aspect will be again the strong focus on presentations that illuminate technical difficulties and highlight open problems.
