• Apache Spark + AI Munich - Metadata Driven Development & Wide Tables #Feb2020

    In this Meetup, we are very happy to have Adidas talk about their Metadata Driven Development for Data Lake Environments and hear Data Reply talk about Pivoting wide tables in Spark, which is a common problem to solve. This event will be hosted by Data Reply together with two great speakers from the community: * Jorge Cespedes (Adidas) * Sadik Bakiu (Data Reply) Talk 1: Metadata Driven Development for Data Lake Environments Talk 2: Pivoting wide tables with Spark TALKS: Title: Metadata Driven Development for Data Lake Environments Abstract: M3D stands for Metadata Driven Development and is a cloud and platform-agnostic framework for the automated creation, management, and governance of metadata and data flows from multiple sources to multiple target systems. It is a tool comprised of two components: m3d-API and m3d-engine. At Adidas the framework is used for the creation of data lake environments, management and governance of metadata, data flows from multiple sources and algorithms as data frame transformations. It is feeding 500+ tables and over 900 views. M3D was made last year open-source and it is available for the community in the Adidas Github account. It is constantly getting new features and improvements from internal teams. Bio: Jorge is the tech lead for Adidas M3D framework, working on making M3D ready for feeding their fast data analytics platform, and actively contributing to the M3D engine since he joined the data engineering team at Adidas almost 2 years ago. He has been working with the Hadoop ecosystem for 5 years and contributed to some open source projects such as Impala and Apache Kudu. Recently, he started exploring AI world experimenting with LSTMs for NLP. Title: Pivoting Wide Tables with Spark Abstract: Pivoting operation is very computation intensive. In cases, when the resulting table will contain more than 10k columns, this operation became especially demanding. In this talk, we will dive into how the current Spark implementation is ineffective in these cases, problems faced during the development and eventually how to implement this operation in a performant way. Bio: Sadik is a data engineer at Data Reply focused on helping customers develop their analytical applications with Spark and other distributed computation frameworks. Sadik is also specialized in developing scalable data processing pipelines in all major cloud providers.

    Globe Business College Munich

    We are delighted to announce our car-focused event this December in Munich. This event will be hosted by Data Insights. together with two great speakers from the community: * Dr. Evan Eames (Data Insights) * Jannis Bergbrede (Inovex) Talk 1: Car Classification Using a Deep Convolutional Neural Network (This talk assumes a basic-to-intermediate understanding of Neural Networks) Talk 2: A Case for Isolated Virtual Environments with PySpark TALKS: Title: Car Classification Using a Deep Convolutional Neural Network Abstract Abstract: In this talk, we will first go through a number of real Use Case examples, involving Convolutional Neural Networks (CNN), and then walk through the development, training, and eventual deployment of a heavy-duty full-scale CNN, in this case used to accomplish car model classification. Finally, we will discuss how this CNN can be easily reworked to accomplish a wide variety of other computer vision tasks. Bio: Dr. Evan Eames completed his PhD in Computational Astrophysics, in which he worked with early-universe full-numerical simulations. He now designs Deep Learning applications, with a focus on industry application. In his free time he's also tinkering with some interesting new ML architectures. You can see some of his projects on his Github: https://github.com/EvanEames Title: A Case for Isolated Virtual Environments with PySpark Abstract: When deploying and using PySpark applications in production, it is often necessary to use Python libraries like pandas, numpy or custom packages on the worker nodes of a spark cluster. Since the cluster is often shared among many users, managing global packages and their versions quickly becomes a hopeless endeavor. Based on practical experience at Germany's largest car market, I will motivate the use of isolated virtual environments for individual jobs. Further, I will talk about best practices on how to build and distribute these environments, leveraging conda requirement definitions and spark-submit functionality. Bio: Jannis Bergbrede completed his Master in Business Informatics at the University of Mannheim. Now he develops big data applications at inovex while focussing on building spark data pipelines and bringing Machine Learning use cases to production.

This event will be hosted by b.telligent together with two great speakers from the graphs community: * Dr. Andreas Hopfgartner & Dr. Sebastian Petry (b.telligent) * Martin Junghanns (Neo4j) Talk 1: Graphs are everywhere!? - Not yet, but maybe soon. Talk 2: Extending Apache Spark Graph for the Enterprise with Morpheus and Neo4j TALKS: Title: Extending Apache Spark Graph for the Enterprise with Morpheus and Neo4j Abstract: Apache Spark 3.0 introduces a new module: Spark Graph. Apache Spark Graph adds the popular query language Cypher, its accompanying Property Graph Model and graph algorithms to the data science toolbox. Graphs have a plethora of useful applications in recommendations, fraud detection, and research. Morpheus is an open-source library that is API compatible with Spark Graph and extends its functionality by: * A Property Graph catalog to manage multiple Property Graphs and Views * Property Graph Data Sources that connect Spark Graph to Neo4j and SQL databases * Extended Cypher capabilities including multiple graph support and graph construction * Built-in support for the Neo4j Graph Algorithms library In this talk, we will walk you through the new Spark Graph module and demonstrate how we extend it with Morpheus to support enterprise users to integrate Spark Graph in their existing Spark and Neo4j installations. We will demonstrate how to explore data in Spark, use Morpheus to transform data into a Property Graph, and then build a Graph Solution in Neo4j. Bio: Martin Junghanns is part of the Morpheus Engineering team at Neo4j and one of the Apache Spark Graph contributors. He has a research background in distributed graph analytics, his main interests are query engines, graph algorithms, and functional programming languages. Martin holds an MSc Computer Science degree from the University of Leipzig. Title: Graphs are everywhere!? - Not yet, but maybe soon. Abstract: In an increasingly interconnected world, mathematical models are often sought to describe these networks and to be able to use network structures. One possibility is graphing. Graphs are defined and described out of the network idea. Subsequently, we transfer this mathematical model to applications outside of networks. Finally, a practical example of the application of graphs is presented. Graphs are everywhere - maybe not, but they could be much more common. "Use Graphs - use connections" Bio: Dr. Sebastian Petry * Development and optimization of analytical methods and tools * Project management * Leadership * Different analytic projects with data science and statistical methods Dr. Andreas Hopfgartner * Physicist with focus on modeling, algorithms and signal processing * Coverage of the complete data science stack with a focus on enterprise IoT * Coverage of the complete data science stack with a focus on enterprise IoT * Sensors, Constraint devices, Embedded Systems / Bus & Networks * Signal Processing * Profound experience in R&D, engineering, software development# HOUSEKEEPING: • 2 talks (each ca. 40 min incl. discussion) • Networking, food & drinks • Language: English • There will be photos taken • A list of registered users will be provided to the host • Please bring your ID
