Talks:

Big Data Analytics in R using sparklyr (Nicola Lambiase, Mirai-Solutions)

Several techniques are available nowadays for scaling data analytics in R. In this presentation we are going to introduce Apache Spark, a general engine for large-scale distributed data processing. We will show how the sparklyr package can be used as a dplyr backend to leverage the resources in a Spark cluster. We will also introduce sparkbq, a sparklyr extension package providing support for Google BigQuery.

Anomaly detection – database integrated (Olaf Nimz, Trivadis)

Still considered as a novelty or already an outlier. How far away should a single case be apart from the rest to qualify as extraordinary? Micro-clusters hide anomalies in certain approaches effectively if not compensated by subsampling. Depending on a local or global perspective sensitivity will change. To make things worse treating high dimensional datasets and mixed datatypes require simplification of the problem.
In this situation there is no silver bullet but a sensible combination of different methods is essential. A few starting points and their preferable aspects are shown and finally applied within a database where data are at home anyway.

The January edition takes place at Impact Hub Zürich (location: Viadukt at Viaduktstrasse 91, 8005 Zurich): The global community of entrepreneurial people prototyping the future of business. At Impact Hub, you can connect, collaborate, co-work and create great content in an inspiring environment.

Snacks and drinks at this event are sponsored by Mirai Solutions.
