Dynamic ensembling pays off for regionwise gains in regression under distribution shift, according to a cross-fitted probe estimate of regionwise convex combination gains over the best static blend.
Read the original at arxiv.org→arXiv:2608.18330v1 Announce Type: new Abstract: Whether input-dependent ("dynamic") combination of a regression model pool beats the best static blend depends on the shift and is rarely known before deployment. Can...
