Our contribution towards differentiable programming: O(n log n) differentiable sorting and ranking operators. Key techniques: projections onto permutahedra & isotonic optimization. Applications to top-k classification, label ranking, least trimmed squares. https://t.co/wjfrxLBFJS pic.twitter.com/7V21zPM8MM
