“…While many algorithms can be interpreted as solving an optimization problems or fixed-point computations and can therefore be improved with amortized optimization, it is also fruitful to use learning to improve algorithms that have nothing to do with optimization. Some key starting references in this space include data-driven algorithm design (Balcan, 2020), learning to prune (Alabi et al, 2019), learning solutions to differential equations Poli et al, 2020;Karniadakis et al, 2021;Kovachki et al, 2021;Chen et al, 2021b;Blechschmidt and Ernst, 2021;Marwah et al, 2021;Berto et al, 2021) learning simulators for physics (Grzeszczuk et al, 1998;Ladickỳ et al, 2015;He et al, 2019;Sanchez-Gonzalez et al, 2020;Wiewel et al, 2019;Usman et al, 2021;Vinuesa and Brunton, 2021), and learning for symbolic math (Lample and Charton, 2019;Charton, 2021;Drori et al, 2021;d'Ascoli et al, 2022) Salimans andHo (2022) progressively amortizes a sampling process for diffusion models.…”
