In this work, a metric of semantic uncertainty\u0000for open-set object detections produced by visual foundation models is\u0000calculated and then incorporated into an object-level uncertainty tracking\u0000framework.

The above loop closure detection problem is formulated\u0000as a graph-matching problem. While graph matching, in general, is NP-Complete,\u0000a solver for an equivalent formulation of the proposed graph matching problem\u0000as a graph editing problem is tested on multiple challenging underwater scenes.\u0000Results for this solver as well as three other solvers demonstrate that the\u0000proposed methods are feasible for real-time use in marine environments for the\u0000robust, open-set, multi-object, semantic-uncertainty-aware loop closure\u0000detection. Further experimental results on the KITTI dataset demonstrate that\u0000the method generalizes to large-scale terrestrial scenes.","PeriodicalId":501031,"journal":{"name":"arXiv - CS - Robotics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As local\u0000computation tends to be restricted, offloading the computation, ie, to a remote\u0000server, can save local resources while providing access to high-quality\u0000predictions from powerful and large models. However, the resulting\u0000communication and latency overhead has led to limited usability of cloud models\u0000in dynamic, safety-critical, real-time settings. To effectively address this\u0000trade-off, we introduce UniLCD, a novel hybrid inference framework for enabling\u0000flexible local-cloud collaboration. By efficiently optimizing a flexible\u0000routing module via reinforcement learning and a suitable multi-task objective,\u0000UniLCD is specifically designed to support the multiple constraints of\u0000safety-critical end-to-end mobile systems. We validate the proposed approach\u0000using a challenging, crowded navigation task requiring frequent and timely\u0000switching between local and cloud operations.

A key challenge is generating a diverse set of future\u0000predictions, commonly addressed using data-driven models with Multiple Choice\u0000Learning (MCL) architectures and Winner-Takes-All (WTA) training objectives.\u0000However, these methods face initialization sensitivity and training\u0000instabilities.

To tackle these issues, we take inspiration from annealed MCL, a\u0000recently introduced technique that improves the convergence properties of MCL\u0000methods through an annealed Winner-Takes-All loss (aWTA). In this paper, we\u0000demonstrate how the aWTA loss can be integrated with state-of-the-art motion\u0000forecasting models to enhance their performance using only a minimal set of\u0000hypotheses, eliminating the need for the cumbersome post-selection step.

In this\u0000paper, we propose a resilient and adaptive framework for multi-robot,\u0000multi-target tracking in environments with unknown sensing and communication\u0000danger zones.

An adaptive replanning strategy is introduced, featuring different\u0000triggers to improve group performance. This approach allows for dynamic\u0000prioritization of target tracking and risk aversion or resilience, depending on\u0000evolving resources and real-time conditions.
