ISEE.U: Distributed online active target localization with unpredictable targets

no code implementations17 Oct 2022 Miguel Vasques, Claudia Soares, João Gomes

This paper addresses target localization with an online active learning algorithm defined by distributed, simple and fast computations at each node, with no parameters to tune and where the estimate of the target position at each agent is asymptotically equal in expectation to the centralized maximum-likelihood estimator.

STRONG: Synchronous and asynchronous RObust Network localization, under Non-Gaussian noise

no code implementations1 Oct 2021 Claudia Soares, João Gomes

We convexify and change the problem representation, to allow for distributed robust localization algorithms: a synchronous distributed method that has optimal convergence rate and an asynchronous one with proven convergence guarantees.

Autonomous orbit determination for satelite formations using relative sensing: observability analysis and optimization

no code implementations19 Sep 2021 Pedro Rocha Cachim, João Gomes, Rodrigo Ventura

Orbit determination of spacecraft in orbit has been mostly dependent on either GNSS satellite signals or ground station telemetry.

CvxPnPL: A Unified Convex Solution to the Absolute Pose Estimation Problem from Point and Line Correspondences

1 code implementation24 Jul 2019 Sérgio Agostinho, João Gomes, Alessio Del Bue

We present a new convex method to estimate 3D pose from mixed combinations of 2D-3D point and line correspondences, the Perspective-n-Points-and-Lines problem (PnPL).

Learning from Demonstration in the Wild

no code implementations8 Nov 2018 Feryal Behbahani, Kyriacos Shiarlis, Xi Chen, Vitaly Kurin, Sudhanshu Kasewa, Ciprian Stirbu, João Gomes, Supratik Paul, Frans A. Oliehoek, João Messias, Shimon Whiteson

Learning from demonstration (LfD) is useful in settings where hand-coding behaviour or a reward function is impractical.

LocDyn: Robust Distributed Localization for Mobile Underwater Networks

no code implementations27 Jan 2017 Cláudia Soares, João Gomes, Beatriz Ferreira, João Paulo Costeira

LocDyn is robust: it rejects outlier noise, while the comparing methods succumb in terms of positioning error.
