In this reflection paper, we advocate for a more systematic evaluation of samplers towards two sources of difficulty that are mode separation and dimension. For this, we propose a synthetic experimental setting that we illustrate on a selection of samplers, focusing on the challenging criterion of recovery of the mode relative importance. These evaluations are crucial to diagnose the potential of samplers to handle multi-modality and therefore to drive progress in the field.<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Louis Grenioux, Maxence Noble, Marylou Gabri&#8217;e<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/arxiv.org\/abs\/2504.08916\">Go to original source<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Improving the evaluation of samplers on multi-modal targets arXiv:2504.08916v1 Announce Type: new Abstract: Addressing multi-modality constitutes one of the major challenges of sampling.
