To solve the problems of nonlinearity in system model, redundancy caused by consensus iterations, and naivety resulting from limited field of view (FOV) of sensors, a novel square-root version distributed nonlinear filter based on information consensus (SRDICF) is proposed. It is developed based on the information weighted consensus protocol with embedded square-root decomposition of the information matrices. The cubature rule is chosen to approximate the Gaussian weighted integral involved in the nonlinear Bayesian filtering paradigm. Then different weights are assigned to the local prior and measurement information to initialize the consensus terms. Finally, the global estimate of each node is acquired with sufficient consensus iterations. The experimental results illustrate that the SRDICF achieves higher estimation accuracy, faster convergence rate and better numerical stability in the existence of naïve nodes and information redundancy. In addition, the SRDICF attains comparable estimation accuracy to the centralized scheme with fewer consensus iterations.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127805976","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}

Partial knowledge can improve the fusion. An implicit constraint on correlation has been introduced in the literature for full-vector estimates. This paper considers fusion of partial estimates.

An analysis of admissible ideal fusions reveals that the considered implicit partial knowledge cannot improve the Covariance Intersection fusion of partial estimates. An exception is found for the strong assumption and fusion of one partial and one full-vector estimate. For this case, an improved fusion rule is presented.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115268771","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}

Recent studies have shown that the Stackelberg model can be an effective tool for security games through optimal resource allocation strategies. Few of these studies focus their attention on wildlife crime or, more generally, green security games in which frequent attacks occur. Furthermore, there does not appear to be a standard way to evaluate the uncertainty and performance of such models. In this work, a simulation platform that emulates realistic movement of rhinos, rangers and poachers in the park, is presented which can ultimately be used for evaluation of game theory models. The game theory model implemented in the simulation platform is evaluated using the uncertainty representation and evaluation framework (URREF) ontology.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126200147","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}

The search under dynamic programming or fixed grid is often computationally nontrivial even for a myopic search scenario. In this paper, we study the problem of an autonomous underwater vehicle planning its return route to a moving recovery vessel. To complicate the issue, the AUV needs to localize the vessel using angle-only measurements. Accordingly, we propose a random sampling based trajectory planning algorithm that incorporates both a dynamic goal and the need to localize that goal. More precisely, we incorporate an information theoretic cost into a rapid-exploring random tree trajectory planning framework thus allowing the AUV to both localize and reach the recovery vessel. Our experimental results show that the proposed method may achieve the same trajectory optimisation performance as that under dynamic programming method but with greater computational efficiency.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128053738","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}

To detect these errors, we simulated their influence on the correlator output on two carrier frequencies. Based upon the simulations, a feature using the difference between an ideal correlator output and the received correlator output was developed. This article presents the new Dual-frequency Post-correlation Difference feature and compares its performance with two methods from the bibliography. This new feature outperforms the Code-Minus-Carrier and the signal-to-noise ratio difference features in multipath and non-line-of-sight detection. Furthermore it can distinguish between multipath and non-line-of-sight reception. As a consequence, the method can be used to exclude satellites whose signals are affected by reflections, to provide a more accurate navigation solution.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125190577","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}

This system serves as a cooperative VHF-radio exchange of navigational and ships' information. Since AIS broadcasts self-declared information, it is open to fraudulent misuse by users. Based on different approaches to classification of maritime vessels, i.e., Random Forest, Voting-2-of-3, Decision Tree, Fuzzy Rule, and $k$ Nearest Neighbor, this contribution addresses the question, up to which accuracy it is possible, to detect fishery vessels with spoofed AIS-type based only on ship's positional, motion, and dimensions' AIS-data. For this purpose, in real-life AIS datasets from early summer 2017 the classification results of AIS fishery type are evaluated and compared.","PeriodicalId":348881,"journal":{"name":"2019 22th International Conference on Information Fusion (FUSION)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121682801","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}

Experiences show, however, journal entries can be inconsistent or incomplete. In this paper we associate the measurements of a wireless electrocardiogram with the measurements of inertial sensors in order to reason about the activities of a person. We put together the raw measurements and their wavelet transform in a three-way tensor and apply tensor decomposition to uncover hidden features which can be vital for detecting the underlying activities.
