Guest Speakers and subjects: 

  1. Chris Gropp, PhD Candidate, Clemson University
    Asking the Right Questions with Machine Learning

    The HPCC Systems Machine Learning Library contains a number of powerful tools, but it is important to use them properly. I will discuss how to ask the right questions, by taking a step backwards from the methods themselves and examining the requirements defined by the applications. Topic models will be used as a case study, but the approach is broadly applicable.

    Chris Gropp's research interests include machine learning, high performance computing, and data analysis. Chris is currently working on refining topic modeling approaches to text analysis, both by improving the algorithms themselves and by developing new methods to analyze output. He is also working with a number of other researchers to apply existing tools to new domains. 


  2. Rodrigo Pastrana, Software Architect, LexisNexis Risk Solutions
    Creating Front-facing Web Services to Deliver your HPCC Systems Query Data

    So you’ve ETL’ed your data, and you’ve created powerful ECL queries, now you need to expose your queries to your customers. The HPCC Systems platform provides everything you need to easily create production grade web services to deliver your query data. Let’s look at the tools and frameworks provided by the HPCC Systems platform, and walk through the end-to-end creation of a sample web service.

    Rodrigo is an Architect with the HPCC systems supercomputer focusing in platform integration and plug-in development. He has been a member of the HPCC Systems core technology team for over five years and a member of the LexisNexis team for seven. Rodrigo is the principle developer of WsSQL, the HPCC Systems JDBC connector, the HPCC Systems Java APIs library and tools, and the Dynamic ESDL component. He has more than fifteen years of experience in design, research and development of state of the art technology including IBM’s embedded text-to-speech and voice recognition products, Eclipse’s device development environment. Rodrigo holds an MS and BS in Computer Engineering from the University of Florida and during his professional career has filed more than ten patent disclosures through the USPTO.

  3. Richard Taylor, Chief Trainer, HPCC Systems
    ECL Tips and Cool Tricks


    Richard Taylor has worked with the HPCC Systems technology platform and the ECL programming language for over 15 years. He is the original author of the ECL documentation, developer and designer of the HPCC Systems Training Courses, and is the Chief Instructor for all classroom and remote based training.

    In this session, we will be parsing the PARSE function. Exploring some interesting PARSE techniques used in date parsing.
