Differentiable sorting framework using optimal transport.

problem Piecewise constant sorting function without gradient information.
method Linking sorting to optimal transport, adding entropic regularization, and approximating with Sinkhorn iterations.
result Differentiable sorting operators (S-sorts, S-CDFs, S-quantiles) for machine learning applications.

Sorting input objects is an important step in many machine learning pipelines. However, the sorting operator is non-differentiable with respect to its inputs, which prohibits end-to-end gradient-based optimization. In this work, we propose NeuralSort, a general-purpose continuous relaxation of the output of the sorting…
