Kleinjohann, Claudius Stern","doi":"10.1109/ICAS.2009.21","DOIUrl":"https://doi.org/10.1109/ICAS.2009.21","url":null,"abstract":"Because imitation has shown to be able to drastically cut down the exploration space it has been embraced largely by the robotics community to speed up autonomous learning. This has been done mostly in fixed demonstrator-imitator relationships, where a predefined demonstrator is performing the same action over and over again until the robot has learned it sufficiently. In practical multi-robot scenarios, however, the imitation process should not interrupt the observed robot as it will affect its autonomy. Therefore the imitating robot often has only a limited amount of behaviors of the same type to learn from. As this usually does not provide enough information for learning a generalized version of observed low-level actions, it can help the observer to optimize its strategy based on the recognized actions. In this case, first of all the imitating robot has to interpret the observed behavior in terms of its own behavior knowledge. This means that low-level observations have to be segmented into episodes of apparently similar behavior. For these episodes corresponding skills in the observing robot's own behavior repertoire have to be found. And for the episodes sequence corresponding state changes in the observing robot's own strategy have to be determined. How the former can be done has been shown by the authors in a previous paper. In this paper we will describe how our approach for emph{Evolving Societies of Learning Autonomous Systems} (ESLAS) is extended to be capable of multi-robot imitation. We demonstrate how the recognition results can be used in a multi-robot scenario to decentrally align the robots' behaviors, to speed up the overall learning process, and thus increase the overall autonomy.","PeriodicalId":258907,"journal":{"name":"2009 Fifth International Conference on Autonomic and Autonomous Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121392514","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}

However, such extensions have been accessible only to system administrators for security reasons. This paper investigates an approach to realize network I/O extensibility without administrator privilege. To this end, we build on a novel virtualization scheme developed for network control, hierarchical virtualization of network interfaces, which allows recursive creation of the virtualized network interfaces and attaches the created interfaces to OS entities, such as sockets and processes. We show that the hierarchical virtualization has desirable properties for safe execution of packet processing code inside OS kernels, even by ordinary users and untrusted applications. For proof-of-concept, functionality of the system is demonstrated by a prototype implementation and execution profiling is taken to verify if such a kernel extensibility can be realized at practical performance overhead. The systematic experiments illustrated that the hierarchical virtualization can realize kernel extensibility without administrator privilege.","PeriodicalId":258907,"journal":{"name":"2009 Fifth International Conference on Autonomic and Autonomous Systems","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133821102","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}

These applications involve several services as health-care services or infotainment, which are executed on different environments such as hospital, proximity doctor, family homes. These environments constitute a distributed, heterogeneous, highly dynamic infrastructure that makes it necessary to build AAL applications as adaptive software including the necessary mechanisms to dynamically modify their behavior. In this paper we propose a multi-level model to build context-aware self-adaptive entities: the basic level defines the mandatory functionalities for adaptive entities, while upper-levels define how to coordinate adaptation of primitive or composite entities. The generic nature of the model is illustrated by its use when building a self-adaptive distributed data management service for an AAL application.","PeriodicalId":258907,"journal":{"name":"2009 Fifth International Conference on Autonomic and Autonomous Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114684791","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}

In this paper we propose a trend model that guarantees a robust interpretation for load-aware decision algorithms.

Many of these applications depend on DBMS that most often suffer direct consequences in their schemas due to changes in the reality that they model. In this work, we propose a new alternative to the issue of schema evolution in multi-database environments, which uses concepts of Autonomic Computing in DBMS to propagate updates in schemas replicated within the same environment, thus ensuring their consistency. Our prototype counts with a Multi-Agent System, which executes events for updating schemas in the target DBMS, which may be of different platforms. Repetitive tasks which are performed in different databases to ensure the evolution of replicated schemas are thus eliminated, freeing the DBA to do other tasks that are more important, such as analysis, database design and strategic management of data.","PeriodicalId":258907,"journal":{"name":"2009 Fifth International Conference on Autonomic and Autonomous Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122781140","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}
