Rank-based Heuristics for Optimizing the Execution of Product Data Models
Konstantinos Varvoutas, Anastasios Gounaris, Georgia Kougka +1
The Product Data Model (PDM) is an example of a data-centric approach to modelling information-intensive business processes, which offers exibility and facilitates process optimiza…
Cost models for geo-distributed massively parallel streaming analytics
Anna-Valentini Michailidou, Anastasios Gounaris, Konstantinos Tsichlas
This report is part of the DataflowOpt project on optimization of modern dataflows and aims to introduce a data quality-aware cost model that covers the following aspects in combin…
Analysis of key flavors of event-driven predictive maintenance using logs of phenomena described by Weibull distributions
Petros Petsinis, Athanasios Naskos, Anastasios Gounaris
This work explores two approaches to event-driven predictive maintenance in Industry 4.0 that cast the problem at hand as a classification or a regression one, respectively, using…
Adaptive filter ordering in Spark
Nikodimos Nikolaidis, Anastasios Gounaris
This report describes a technical methodology to render the Apache Spark execution engine adaptive. It presents the engineering solutions, which specifically target to adaptively r…
Continuous Outlier Mining of Streaming Data in Flink
Theodoros Toliopoulos, Anastasios Gounaris, Kostas Tsichlas +2
In this work, we focus on distance-based outliers in a metric space, where the status of an entity as to whether it is an outlier is based on the number of other entities in its ne…
Speeding-up the Verification Phase of Set Similarity Joins in the GPGPU paradigm
Christos Bellas, Anastasios Gounaris
We investigate the problem of exact set similarity joins using a co-process CPU-GPU scheme. The state-of-the-art CPU solutions split the wok in two main phases. First, filtering an…
