Abstract: One of the most natural optimization problems is the k-SET PACKING problem, where given a family of sets of size at most k one should select a maximum size subfamily of pairwise disjoint ...
We ask how far the choice of which moments to match can push estimates in misspecified structural models. The answer is: very far. Under regularity conditions, an adversarial researcher informed about ...
Tensor networks enable researchers to tackle quantum physics problems previously thought to be solvable only by quantum computers. Credit: Lucy Reading-Ikkanda/Simons Foundation By applying a 1980s ...
