Analytics to the masses by JOSE LUIS LÓPEZ at Big Data Spain 2014

In this talk, we will discuss our approach to bring large scale deep analytics to the masses. R is an extremely popular numerical computer environment, but scientific data processing frequently hits its memory limits. On the other hand, system to execute data intensive tasks like Hadoop or Stratosphere are not popular among R users because writing programs using these paradigms is cumbersome. We present an innovative approach to overcome these limitations using the Stratosphere/Apache Flink big data platform by means of a R package and ready-to-use distributed algorithm.

  1. Big Data Analytics to the masses Why it has failed

    and how we can fix it Jose Luis Lopez Pino
  2. Big Data is like Tourism But if you aren’t an

    expert, you can’t make the most of it It seems easy to do
  3. Struggle to analyze Big Data Harlan Harris, Sean Murphy, and

    Marck Vaisman. Analyzing the Analyzers: An Introspective Survey of Data Scientists and Their Work. O’Reilly Media, Inc., 2013 Also: Sean Kandel, Andreas Paepcke, Joseph M Hellerstein, and Jeffrey Heer. Enterprise data analysis and visualization: An interview study. Visualization and Computer Graphics, IEEE Transactions

    and data independence in the big data era. Proceedings of the VLDB Endowment, 7(13), 2014

    declarative data analysis and data independence in the big data era. Proceedings of the VLDB Endowment, 7(13), 2014
  6. Say it with memes! When you do Deep analytics in

    small data using R and CRAN packages When you do deep analytics in BIG data using R and CRAN packages
  7. When you try to program it using MapReduce When you

    try to program it using Apache Spark / Apache Flink When you try to use a library scalable to large data sets
  8. Can’t we do it better? - Make it similar to

    normal R programs. - Hide complexity. - Make file manipulation easier. - Part of the computing in the cluster and part of the computer in the client.
  9. Some relevant findings - Transmission time was not significant. -

    Stratosphere/Flink was competitive in highly iterative programs. - We were not able to do it keeping the code 100% the same. - Ensemble scenarios are the most exciting ones.
  10. 4 Takeaways from this talk - We still need to

    bring Big Data to the right people in the right place. - We need comprehensive libraries. - We need to move data back and forth. - Use a syntax that the users are familiar with.
  11. That’s all! - Have you found this talk interesting? -

    Follow me: @jllopezpino - Interested in a job as SEM Data Analyst (Berlin)? - Ask me for the details: - Are you interested in Data + Energy? - Keep in touch:
