Learn to Match: Two-Sided Matching with Temporally Extended Feedback
Announce Type: new Abstract: Two-sided matching markets often involve information that unfolds over time through interviews, repeated interaction, learning, and separation. Existing matching models typically reduce this process to immediate sub-Gaussian feedback about fixed preferences, missing settings where payoff-relevant information is revealed gradually and changes future matching decisions. We introduce a framework with temporally extended feedback, that formulates two-sided matching...
Q-VGM: Q-Guided Value-Gradient Matching for Flow-Matching VLA Policies
Announce Type: new Abstract: We propose Q-Guided Value-Gradient Matching (Q-VGM), an off-policy reinforcement learning (RL) method that tackles a long-standing challenge in fine-tuning flow-matching vision-language-action (VLA) policies: efficiently improving an expressive flow-matching action expert with respect to a learned Q-function. Effective improvement must exploit the first-order (gradient) information of the critic, but this is difficult for flow policies, because directly...
Redefining Instance Matching: A Unified Framework for Part-Aware Matching in Panoptic Segmentation Evaluation
Announce Type: new Abstract: The Panoptic Quality (PQ) metric is the standard for jointly evaluating instance and semantic segmentation. However, its original definition relies on a One-to-One matching between predicted and ground truth segments, which is only straightforward when the IoU threshold exceeds 0.5. Below 0.5, multiple matching strategies emerge in a poorly explored problem space.
Service Preservation from Matching Non-Matching Socks Under Stochastic Loss
arXiv:2602.18221v2 Announce Type: replace Abstract: Socks are produced and replaced at a massive scale, yet their paired use makes them unusually vulnerable to service loss, as the disappearance of a single sock can leave usable wear-capacity stranded and create sockless days even when functional socks remain available. In this study, we examine whether pairing non-matching \say{orphan} socks can preserve daily sock service under stochastic loss, and how this benefit trades off against...
On Thin Perfect Matchings up to Polylogarithmic Factors
arXiv:2606.01330v1 Announce Type: new Abstract: We resolve the thin matching problem proposed by Anari, Charikar and Ramakrishnan [ACR23] up to polylogarithmic factors. Given a fractional perfect matching $x$, we say a perfect matching $M$ is $\alpha$-thin w.r.t. $x$ if for any cut $(S,\overline{S})$, we have $$ |M \cap E(S,\overline{S})| \leq \alpha\cdot x(S,\overline{S}).$$ [ACR23] conjectured that for any fractional perfect matching $x$, there exists a perfect matching $M$ which is...

Online Min-Cost Matching with General Arrivals
arXiv:2606.05546v1 Announce Type: new Abstract: In the classic online min-cost matching problem, the goal is to match a sequence of requests that arrive dynamically over time to a set of static servers, aiming to minimize the total cost of the matching. This assumes that there are two distinct "sides" and that only one of these sides arrives online, but many of the motivating applications violate these assumptions. We study online min-cost perfect-matching when \emph{all} participants arrive...

Temporal matching in trees
arXiv:2606.06439v1 Announce Type: new Abstract: We study maximum matching problems in temporal graphs whose underlying graph is a tree. We consider two temporal models. In a $\Delta$-matching, selected time edges sharing an endpoint must have time ticks differing by at least $\Delta$. In a $\gamma$-matching, the selected objects are blocks of $\gamma$ consecutive appearances of the same underlying edge.
