A new frontier in novelty detection: Pattern recognition of stochastically episodic events
2011
Published version of an article from the book: Intelligent Information and Database Systems, Lecture Notes in Computer Science. Also available from the publisher on SpringerLink:http://dx.doi.org/10.1007/978-3-642-20039-7_44 A particularly challenging class of PR problems in which the, generally required, representative set of data drawn from the second class is unavailable, has recently received much consideration under the guise of One-Class (OC) classification. In this paper, we extend the frontiers of OC classification by the introduction of a new field of problems open for analysis. In particular, we note that this new realm deviates from the standard set of OC problems based on the fo…
Learning automata-based solutions to the optimal web polling problem modelled as a nonlinear fractional knapsack problem
2011
Accepted version of an article from the journal: Engineering Applications of Artificial Intelligence. Definitive published version on Elsevier Science Direct: http://dx.doi.org/10.1016/j.engappai.2011.05.018 We consider the problem of polling web pages as a strategy for monitoring the world wide web. The problem consists of repeatedly polling a selection of web pages so that changes that occur over time are detected. In particular, we consider the case where we are constrained to poll a maximum number of web pages per unit of time, and this constraint is typically dictated by the governing communication bandwidth, and by the speed limitations associated with the processing. Since only a fra…
Interplay Between Sustainable Development, Knowledge Society, and Smart Future Manufacturing Technologies in EU RTD Policy Documents, in the Work Pro…
2015
Modern societies create, share and use knowledge to grow wealth and well-being, in other words—to follow the principles of sustainable development on a broader scale. In such societies jobs no longer depend on basic manufacturing but on gaining and smartly applying the knowledge instead: developing and using the manufacturing technologies more efficiently. A knowledge-based society addresses the socio-economic challenges by international and inter-sectorial sharing of knowledge crucial for innovation. Sustainable development is a core EU objective ensuring our future being not compromised by our present socio-economic development. Policy-makers at the EU and Member State level have agreed t…
Gouvernance contractuelle et cognitive des alliances internationales en R&D
2009
Notre objectif est d’expliquer le choix des firmes multinationales entre les alliances avec prise de participation et les alliances sans prise de participation pour investir en R&D à l’étranger. Les déterminants du choix peuvent être contractuels ou cognitifs. Nos résultats montrent que les alliances sans prise de participation sont choisies en cas d’une spécificité des actifs et de fréquence moyennes ou faibles des transactions et au cas où les firmes parentes détiennent des capacités en R&D similaires. Nos résultats montrent aussi que les firmes multinationales n’optent pas nécessairement pour les alliances à fort degré d’interdépendance organisationnelle dans un objectif d’exploration de…
Knowledge management – a source of sustainable competitiveness in the knowledge based economy
2006
Confirming the well known thesis knowledge is power, A. Toffler argued that the knowledge based society represents the acme of the human society development and P. Drucker said that the developed countries passing through the knowledge based society represents the biggest change of the modern world. That made possible and helped the emerging of the managerial revolution (defined as knowledge applied to knowledge itself) at the firm’s level. Under these circumstances, knowledge has to be seen as a strategic resource – source of competitive advantages and of managerial performances as well. Considering this, a firm’s management have to define a coherent behavioral model in order to seriously …
Using artificial intelligence techniques for strategy generation in the Commons game
2011
Published version of a chapter in the book: Hybrid Artificial Intelligent Systems. Also available from the publisher on SpringerLink: http://dx.doi.org/10.1007/978-3-642-21219-2_7 In this paper, we consider the use of artificial intelligence techniques to aid in discovery of winning strategies for the Commons Game (CG). The game represents a common scenario in which multiple parties share the use of a self-replenishing resource. The resource deteriorates quickly if used indiscriminately. If used responsibly, however, the resource thrives. We consider the scenario one player uses hill climbing or particle swarm optimization to select the course of action, while the remaining N − 1 players us…
A New Tool for the Modeling of AI and Machine Learning Applications: Random Walk-Jump Processes
2011
Published version of an article from the book: Hybrid artificial intelligent systems, Lecture notes in computer science. The original publication is available at www.springerlink.com, http://dx.doi.org/10.1007/978-3-642-21219-2_2 There are numerous applications in Artificial Intelligence (AI) and Machine Learning (ML) where the criteria for decisions are based on testing procedures. The most common tools used in such random phenomena involve Random Walks (RWs). The theory of RWs and its applications have gained an increasing research interest since the start of the last century. [1]. In this context, we note that a RW is, usually, defined as a trajectory involving a series of successive ran…
Knowledge organization for modelling workflows in Taverna environment
2014
Today Workflow Management Systems (WFMS), like Taverna and Kepler, have a very important place in the everyday work of the scientist. These tools support the access to computational resources and act as interface for building complex data processing chains. The next step is to support decisions of the researcher on autonomously developing workflow parts guided by requirements of the scientist while she/he is working on the high-level goal of the experiment. To this aim, it is necessary an ontology to store the knowledge related to the experiments and tools used, and to make this knowledge available not only to the scientist, but also to a suitable artificial intelligent system. In this pape…
On utilizing dependence-based information to enhance micro-aggregation for secure statistical databases
2011
Published version of an article in the journal: Pattern Analysis and Applications. Also available from the publisher at: http://dx.doi.org/10.1007/s10044-011-0199-9 We consider the micro-aggregation problem which involves partitioning a set of individual records in a micro-data file into a number of mutually exclusive and exhaustive groups. This problem, which seeks for the best partition of the micro-data file, is known to be NP-hard, and has been tackled using many heuristic solutions. In this paper, we would like to demonstrate that in the process of developing micro-aggregation techniques (MATs), it is expedient to incorporate information about the dependence between the random variable…
Learning high-level manipulative tasks through imitation
2006
This paper presents ConSCIS, Conceptual Space based Cognitive Imitation System, which tightly links low-level data processing with knowledge representation in the context of robot imitation. Our focus is on the program-level imitation: we are interested in the final effects of actions on objects, and not on the particular kinematic or dynamic properties of the motion. The same architecture is used both to analyze and represent the task to be imitated, and to perform the imitation by generalizing in novel and different circumstances. The implemented experimental scenario is a two dimensional world populated with various objects in which observation/imitation takes place. To validate our appr…
