New framework enables differentiable Knapsack and Top-k operators via dynamic programming

Researchers have developed a new framework that treats Knapsack and Top-k operators as dynamic programming problems, enabling their integration into neural networks. This approach uses differentiable relaxations to overcome the challenge of zero gradients in these discrete operators. The framework includes efficient parallel algorithms for both forward and backward passes, theoretical insights into regularization choices, and experimental validation on tasks like learning Knapsack solutions and constrained reinforcement learning.
