Locating people in indoor environments has numerous applications in robotics, crowd control, indoor facility optimization, and automated environment mapping. However, existing WiFi-based positioning systems suffer from two major problems: (1) their accuracy and precision is limited due to inherent noise induced by indoor obstacles, and (2) they only occasionally provide location estimates, namely when a WiFi-equipped device emits a signal. To mitigate these two issues, we propose a novel Gaussian process (GP) model for WiFi signal strength measurements. It allows for simultaneous smoothing (increasing accuracy and precision of estimators) and interpolation (enabling continuous sampling of location estimates). Furthermore, simple and efficient smoothing methods for location estimates are introduced to improve localization performance in real-time settings. Experiments are conducted on two data sets from a large real-world commercial indoor retail environment. Results demonstrate that our approach provides significant improvements in terms of precision and accuracy with respect to unfiltered data. Ultimately, the GP model realizes continuous location sampling with consistently high quality location estimates.","lang":"eng"}],"citation":{"chicago":"Engelen, J.E. van, J.J. van Lier, F.W.

It is widely popular in marketing or medical applications and used to identify groups of similar objects. Clustering possibly unbounded and evolving data streams is of particular interest due to the widespread deployment of large and fast data sources such as sensors. The vast majority of stream clustering algorithms employ a two-phase approach where the stream is first summarized in an online phase. Upon request, an offline phase reclusters the aggregations into the final clusters. In this setup, the online component will idle and wait for the next observation in times where the stream is slow. This paper proposes a new stream clustering algorithm called evoStream which performs evolutionary optimization in the idle times of the online phase to incrementally build and refine the final clusters. Since the online phase would idle otherwise, our approach does not reduce the processing speed while effectively removing the computational overhead of the offline phase. In extensive experiments on real data streams we show that the proposed algorithm allows to output clusters of high quality at any time within the stream without the need for additional computational resources."}],"citation":{"chicago":"Carnein, Matthias, and Heike Trautmann. “EvoStream — Evolutionary Stream Clustering Utilizing Idle Times.” <i>Big Data Research</i> 14 (2018): 101–111. <a href=\"https://doi.org/10.1016/j.bdr.2018.05.005\">https://doi.org/10.1016/j.bdr.2018.05.005</a>.","short":"M.

Target region-based multiobjective evolutionary algorithms (TMOEAs), aiming at a well-distributed subset of Pareto optimal solutions within the user-provided region(s), are extensively investigated in this paper.

Experimental results show that T-SMS-EMOA has the best overall performance regarding the hypervolume indicator within the target region, while T-NSGA-II is the fastest algorithm. We also compare TMOEAs with other state-of-the-art preference-based approaches, i.e., DF-SMS-EMOA, RVEA, AS-EMOA and R-NSGA-II to show the advantages of TMOEAs. A case study in the mission planning of earth observation satellite is carried out to verify the capabilities of TMOEAs in the real-world application.

We first discuss the basic variants of the method that use gradient information and describe subsequently modifications that allow for a gradient free realization. Finally, we show that 𝜆-DS can be used to understand the behavior of stochastic local search within PMOPs to a certain extent which might be interesting for the development of future local search engines, or evolutionary strategies, for the treatment of such problems.

However, many companies rely on different software solutions to handle each channel, which leads to heterogeneous IT infrastructures and isolated data sources. Omni-Channel CRM is a holistic approach towards a unified view on the customer across all channels. This paper introduces three case studies which demonstrate challenges of omni-channel CRM and the value it can provide. The first case study shows how to integrate and visualise data from different sources which can support operational and strategic decision. In the second case study, a social media analysis approach is discussed which provides benefits by offering reports of service performance across channels. The third case study applies customer segmentation to an online fashion retailer in order to identify customer profiles.","lang":"eng"}],"date_created":"2023-08-04T15:05:43Z","department":[{"_id":"34"},{"_id":"819"}],"type":"conference","author":[{"first_name":"Matthias","last_name":"Carnein","full_name":"Carnein, Matthias"},{"full_name":"Heuchert, Markus","last_name":"Heuchert","first_name":"Markus"},{"first_name":"Leschek","last_name":"Homann","full_name":"Homann, Leschek"},{"orcid":"0000-0002-9788-8282","first_name":"Heike","last_name":"Trautmann","full_name":"Trautmann, Heike","id":"100740"},{"first_name":"Gottfried","last_name":"Vossen","full_name":"Vossen, Gottfried"},{"full_name":"Becker, Jörg","first_name":"Jörg","last_name":"Becker"},{"first_name":"Karsten","last_name":"Kraume","full_name":"Kraume, Karsten"}],"publication_identifier":{"isbn":["978-3-319-70625-2"]},"year":"2017","title":"Towards Efficient and Informative Omni-Channel Customer Relationship Management","intvolume":"     10651","date_updated":"2023-10-16T13:36:40Z","language":[{"iso":"eng"}],"series_title":"Lecture Notes in Computer Science","doi":"10.1007/978-3-319-70625-2_7","citation":{"ieee":"M.

Companies aim to provide a better customer ex- perience by offering more convenient channels to contact a company. In addition, this unburdens traditional channels which are costly to maintain.

Different use-cases, including training new learners, querying and reasoning are exemplified and show remarkable benefit for both EMO and MCDM communities."}],"language":[{"iso":"eng"}],"doi":"10.1007/978-3-319-54157-0_28","year":"2017","title":"Building and Using an Ontology of Preference-Based Multiobjective Evolutionary Algorithms","author":[{"full_name":"Li, L","first_name":"L","last_name":"Li"},{"last_name":"Yevseyeva","first_name":"I","full_name":"Yevseyeva, I"},{"last_name":"Basto-Fernandes","first_name":"V","full_name":"Basto-Fernandes, V"},{"full_name":"Trautmann, Heike","first_name":"Heike","orcid":"0000-0002-9788-8282","last_name":"Trautmann","id":"100740"},{"last_name":"Jing","first_name":"N","full_name":"Jing, N"},{"full_name":"Emmerich, M","first_name":"M","last_name":"Emmerich"}],"publication_identifier":{"isbn":["978-3-319-54157-0"]},"date_updated":"2023-10-16T13:35:17Z","place":"Cham","citation":{"mla":"Li, L., et al. “Building and Using an Ontology of Preference-Based Multiobjective Evolutionary Algorithms.” <i>Evolutionary Multi-Criterion Optimization: 9$^th$ International Conference, EMO 2017, Münster, Germany, March 19-22, 2017, Proceedings</i>, edited by H Trautmann et al., Springer International Publishing, 2017, pp. 406–421, doi:<a href=\"https://doi.org/10.1007/978-3-319-54157-0_28\">10.1007/978-3-319-54157-0_28</a>.","ama":"Li L, Yevseyeva I, Basto-Fernandes V, Trautmann H, Jing N, Emmerich M.

Several approaches exist for solving this problem using exact and heuristic techniques, however all of them use a single objective function for determining an optimal solution.

As the first multi-objective approach in the area of liner shipping routing, we show that giving more options to decision makers need not be costly. Indeed, our approach requires no extra runtime than a weighted objective heuristic and provides a rich set of solutions along the Pareto front."}],"date_created":"2023-08-04T15:03:17Z","type":"book_chapter","department":[{"_id":"34"},{"_id":"819"}]},{"abstract":[{"lang":"eng","text":"This paper proposes a new stream clustering algorithm for text streams.

They are considered to be capable of massively distributing propaganda in social and online media, and their application is even suspected to be partly responsible for recent election results. Astonishingly, the term social bot is not well defined and different scientific disciplines use divergent definitions. This work starts with a balanced definition attempt, before providing an overview of how social bots actually work (taking the example of Twitter) and what their current technical limitations are. Despite recent research progress in Deep Learning and Big Data, there are many activities bots cannot handle well. We then discuss how bot capabilities can be extended and controlled by integrating humans into the process and reason that this is currently the most promising way to realize meaningful interactions with other humans. This finally leads to the conclusion that hybridization is a challenge for current detection mechanisms and has to be handled with more sophisticated approaches to identify political propaganda distributed with social bots."}],"citation":{"mla":"Grimme, C., et al. “Social Bots: Human-Like by Means of Human Control?” <i>Big Data</i>, vol. 5, no. 4, 2017, pp. 279–293, doi:<a href=\"https://doi.org/10.1089/big.2017.0044\">10.1089/big.2017.0044</a>.","apa":"Grimme, C., Preuss, M., Adam, L., &#38; Trautmann, H.

A key research area in this field is stream clustering which aims to recognize patterns in a possibly unbounded data stream of varying speed and structure. Over the past decades a multitude of new stream clustering algorithms have been proposed. However, to the best of our knowledge, no rigorous analysis and comparison of the different approaches has been performed. Our paper fills this gap and provides extensive experiments for a total of ten popular algorithms. We utilize a number of standard data sets of both, real and synthetic data and identify key weaknesses and strengths of the existing algorithms.","lang":"eng"}],"place":"Siena, Italy","date_created":"2023-08-04T15:04:09Z","type":"conference","department":[{"_id":"34"},{"_id":"819"}]},{"volume":10079,"editor":[{"last_name":"et al.

Until very recently, these configuration procedures were limited to optimising a single performance objective, such as the running time or solution quality achieved by the algorithm being configured. However, in many applications there is more than one performance objective of interest. This gives rise to the multi-objective automatic algorithm configuration problem, which involves finding a Pareto set of configurations of a given target algorithm that characterises trade-offs between multiple performance objectives. In this work, we introduce MO-ParamILS, a multi-objective extension of the state-of-the-art single-objective algorithm configuration framework ParamILS, and demonstrate that it produces good results on several challenging bi-objective algorithm configuration scenarios compared to a base-line obtained from using a state-of-the-art single-objective algorithm configurator.","lang":"eng"}],"publication":"LION 2016: Learning and Intelligent Optimization"},{"doi":"10.1007/978-3-319-31153-1_4","language":[{"iso":"eng"}],"date_updated":"2023-10-16T13:37:33Z","author":[{"last_name":"Rudolph","first_name":"G","full_name":"Rudolph, G"},{"first_name":"O","last_name":"Schütze","full_name":"Schütze, O"},{"id":"100740","full_name":"Trautmann, Heike","orcid":"0000-0002-9788-8282","first_name":"Heike","last_name":"Trautmann"}],"publication_identifier":{"isbn":["978-3-319-31153-1"]},"title":"On the Closest Averaged Hausdorff Archive for a Circularly Convex Pareto Front","year":"2016","department":[{"_id":"34"},{"_id":"819"}],"type":"book_chapter","date_created":"2023-08-04T15:09:14Z","abstract":[{"text":"The averaged Hausdorff distance has been proposed as an indicator for assessing the quality of finitely sized approximations of the Pareto front of a multiobjective problem.

In this paper, we extract the relevant features (for detecting funnels) out of a large set of landscape features when only given a small initial sample consisting of 50 x D observations, where D is the number of decision space dimensions. This is already in the range of the start population sizes of many evolutionary algorithms.
