Streaming outlier detection
Description
Datalab is a pioneer in streaming distance-based outlier detection and contributes outlier detection functionalities to the well-known “MOA Machine Learning for Streams” tool.
MOA is the most popular open source framework for data stream mining, with a very active growing community (blog). It includes a collection of machine learning algorithms (classification, regression, clustering, outlier detection, concept drift detection and recommender systems) and tools for evaluation. Related to the WEKA project, MOA is also written in Java, while scaling to more demanding problems.

Elton
Description
A Cloud Resource Scaling-Out Manager for NoSQL Databases. We present the Elton tool, a publicly available cloud resource elasticity management system tailored to NoSQL data- bases. Elton is integrated in the Ganetimgr web platform, and offers an easy to use web interface, through which monitoring and horizontal scaling of NoSQL databases can be performed and what-if analysis queries are enabled. Elton uses Markov Decision Processes (MDPs) as the underlying modeling frame- work, and encapsulates state-of-the-art horizontal scaling policies that offer different trade-offs between performance and monetary deployment cost. Its main novelty is that it employs probabilistic model checking to allow for both efficient elasticity decisions and analysis of scaling actions and serves as a case study about the benefits of model checking in online decision making and analysis.

TweetFix
Description
TweetFix is a task that is part of the “Fix the Fixing” E.U. Erasmus+ project. The project goal is to find, analyze and extract useful information about fixed or suspected matches of various sports and events. At this task (WP5,A26: Report on qualitative content identification methodology) our team (Informatics Department, Aristotle University of Thessaloniki, Greece) had been assigned the task of supporting the digital side of the “fix the fixing” addressed problems, with a focus on understanding the social networks impact related to sports fixing. Therefore, an analysis on social networks data involved the processes of : collecting social media data, analyzing them, exporting useful results in readable and understandable graphs and presenting them in this report.
