Using NWP to assess the influence of the Arctic atmosphere on mid-latitude weather and climate [PDF]
, 2017 The influence of the Arctic atmosphere on Northern Hemisphere mid-latitude tropospheric weather and climate is explored by comparing the skill of two sets of 14-day weather forecast experiments using the ECMWF model with and without relaxation of the ...

Characterizing approximate-matching dependencies in formal concept analysis with pattern structures [PDF]
, 2018 Functional dependencies (FDs) provide valuable knowledge on the relations between attributes of a data table. A functional dependency holds when the values of an attribute can be determined by another. It has been shown that FDs can be expressed in terms

Deep learning for gradient flows using the Brezis–Ekeland principle [PDF]
, 2023 summary:We propose a deep learning method for the numerical solution of partial differential equations that arise as gradient flows. The method relies on the Brezis–Ekeland principle, which naturally defines an objective function to be minimized, and so ...
