A bstract We propose an explicit realization of flat space holography in two dimensions where both sides the duality are independently defined and boundary theory is completely solvable. In bulk, we define a novel

Constraining ill-posed inverse problems often requires regularized optimization. I describe two alternative approaches to regularization. The first approach involves a column operator and an extension of the data space. The second approach constructs a row operator and expands the model space. In large-scale problems, when the optimization is incomplete, the two methods of regularization behave...
