Junhyuk Kwon and coauthors propose ProCompNav for ambiguous robot navigation

Markdown · JSON · Original source

The paper’s authors propose ProCompNav, a way for robots to identify which of several similar objects a user means without relying on long, open-ended answers. In interactive instance navigation, the robot first builds a candidate pool, then uses Recursive Comparative Judgment (RCJ): it asks binary questions about attribute-value pairs that divide the candidates and removes options inconsistent with the user’s answers. The method does not require an attribute unique to the intended target. The authors report that ProCompNav substantially improves Success Rate and reduces Response Length on an interactive navigation , and has the highest Success Rate among evaluated methods on a non-interactive benchmark. In two human studies, participants preferred its binary questions over open-ended ones, and batched delivery over interleaved interaction. The argument is that robot design should consider task performance and the burden and experience of interaction together. The abstract reports benchmark and study outcomes, but does not give their numerical results or details of the evaluation settings.

attribution — pass: The title credits Junhyuk Kwon and coauthors, matching the listed authors. The summary attributes the method, results and argument to the paper's authors, and frames outcomes as what the authors report rather than established fact.

Authors:Junhyuk Kwon, Seungjoon Lee, Hyejin Park, Kyle Min, Jungseul Ok

summary — pass: The reading leads with the actor and the problem: a robot must work out which of several similar objects a user means without long answers. It explains the two-stage method and RCJ in plain language, reports results with their scope, and preserves the authors' closing argument about performance and interaction burden. 'Batched delivery' versus 'interleaved interaction' is left unexplained, but it is secondary and the abstract does not define it. The question addresses a genuine gap. The reading also omits the authors' critique of prior methods' premature decisions; this is minor.

an agent must identify and reach the user-intended target among similar objects

date — pass: originalPublished is 2026-05-07, which matches the v1 submission date. It is not the v5 revision date of 5 Nov 2026 or the feed date.

Submitted on 7 May 2026 (v1), last revised 5 Nov 2026 (this version, v5)

support — pass: Every claim is directly backed by the abstract. The benchmark gains are kept as author-reported results limited to the evaluated benchmarks. The human-study preferences are not inflated. The limitations correctly note that the abstract gives no numerical results, evaluation details or study participant details. The reading makes no unsupported claims about benefits or real-world reliability.

ProCompNav substantially improves Success Rate and reduces Response Length on an interactive navigation benchmark

media — pass: The selected media is the verified direct arXiv abstract page for this paper, which is the original source. No other media candidates were found.
