Monitoring and Diagnosability of Perception Systems

no code implementations11 Nov 2020 Pasquale Antonante, David I. Spivak, Luca Carlone

The resulting temporal diagnostic graphs (i) provide a framework to reason over the consistency of perception outputs -- across modules and over time -- thus enabling fault detection, (ii) allow us to establish formal guarantees on the maximum number of faults that can be uniquely identified in a given perception system, and (iii) enable the design of efficient algorithms for fault identification.

Outlier-Robust Estimation: Hardness, Minimally Tuned Algorithms, and Applications

no code implementations29 Jul 2020 Pasquale Antonante, Vasileios Tzoumas, Heng Yang, Luca Carlone

We extend ADAPT and GNC to the case where the user does not have prior knowledge of the inlier-noise statistics (or the statistics may vary over time) and is unable to guess a reasonable threshold to separate inliers from outliers (as the one commonly used in RANSAC).

Monitoring and Diagnosability of Perception Systems

no code implementations24 May 2020 Pasquale Antonante, David I. Spivak, Luca Carlone

Towards this goal, we draw connections with the literature on self-diagnosability for multiprocessor systems, and generalize it to (i) account for modules with heterogeneous outputs, and (ii) add a temporal dimension to the problem, which is crucial to model realistic perception systems where modules interact over time.

Graduated Non-Convexity for Robust Spatial Perception: From Non-Minimal Solvers to Global Outlier Rejection

4 code implementations18 Sep 2019 Heng Yang, Pasquale Antonante, Vasileios Tzoumas, Luca Carlone

In this paper, we enable the simultaneous use of non-minimal solvers and robust estimation by providing a general-purpose approach for robust global estimation, which can be applied to any problem where a non-minimal solver is available for the outlier-free case.

Outlier-Robust Spatial Perception: Hardness, General-Purpose Algorithms, and Guarantees

1 code implementation27 Mar 2019 Vasileios Tzoumas, Pasquale Antonante, Luca Carlone

First, we show that even a simple linear instance of outlier rejection is inapproximable: in the worst-case one cannot design a quasi-polynomial time algorithm that computes an approximate solution efficiently.
