  • Why MAP and MRR Fail for Search Ranking (and What to Use Instead)

    Why MAP and MRR Fail for Search Ranking (and What to Use Instead) MAP and MRR look intuitive, but they quietly break ranking evaluation. Here’s why these metrics mislead—and how better alternatives fix it. The post Why MAP and MRR Fail for Search Ranking (and What to Use Instead) appeared first on Towards Data Science.…

  • Estimation of Stochastic Optimal Transport Maps

    Estimation of Stochastic Optimal Transport Maps arXiv:2512.09499v1 Announce Type: new Abstract: The optimal transport (OT) map is a geometry-driven transformation between high-dimensional probability distributions which underpins a wide range of tasks in statistics, applied probability, and machine learning. However, existing statistical theory for OT map estimation is quite restricted, hinging on Brenier’s theorem (quadratic cost,…

  • Sample and Map from a Single Convex Potential: Generation using Conjugate Moment Measures

    Sample and Map from a Single Convex Potential: Generation using Conjugate Moment Measures arXiv:2503.10576v1 Announce Type: new Abstract: A common approach to generative modeling is to split model-fitting into two blocks: define first how to sample noise (e.g. Gaussian) and choose next what to do with it (e.g. using a single map or flows). We…
