Basis Pursuit
Here is a very interesting paper on the use of Basis Pursuit to find a correlation between different parametric models and data from time dependent PET scans. The nice thing that makes it clear is that there is no need for an ad-hoc procedure to make sure that some coefficients are non-negative (non physical.) We have this kind of problem in neutron transport. In that area, ways to deal with this type of problems are called flux fixing.
