In this work we present the solution to the DEBS'2013 Grand Challenge, as crafted by the joint effort of teams from the Technion and TU Dortmund. The paper describes the architecture, details the queries, shows throughput and latency evaluation, and offers our observations regarding the appropriate way to trade-off high-level processing with time(More)
In a cooperative effort between SMS Siemag AG (SMS), AG der Dillinger Hüttenwerke (DH), and the Chair for Artificial Intelligence of the TU Dortmund University (TUD), modern data mining and machine learning algorithms have been closely integrated with steel processing by a newly developed modular, distributed and scalable data-stream processing system. It(More)
The predator-prey model--based on aspects of the natural interplay of predators and prey--has become an alternative method for tackling multi-objective optimization problems. In this process, each predator targets a single objective, and it is expected that the joint influence of all predators affects the prey population in such a way that good solutions(More)
RapidMiner has become a valuable tool for business intelligence as well as in highschool education. Its plugin mechanism allows for creating powerful extensions and various plugins exist for different applications, data formats and learning schemes. In this paper we present the RapidMiner Beans library, a simple library and plugin that aims at simplifying(More)
