Closing Keynote by Dr. Kirk Borne

@kirkdborne kirkdborne

Dr. Kirk Borne Data Science: From NASA Astrophysics to Digital Marketing to "Lost in Space": The analytics profession may disappear as quickly as it has appeared. The reason: the art and science of learning from data, deriving insights from data, driving decisions with data, and building revenue streams from data are all becoming the new normal in today's digital workplace. Digital science, digital business, digital government, digital health, digital warfare, digital education, digital life, etc. are the norm, not the exception. Analytics professionals will become blended into the workforce seamlessly, in the same way that every worker now works with I.T., without being labeled an "I.T. professional". I will describe numerous data science pathways that I have followed and experienced in the past 15 years that have been as varied as they have been remarkable (from NASA Astrophysics to Data Science Education to Marketing Analytics, and more), with a view toward where these types of analytical paths might be leading all of us.

Mapping the Brain at Scale with Spark by Jeremy Freeman

@thefreemanlab thefreemanlab

Jeremy Freeman To understand the brain, we need to record from as much of it as possible. New technologies are enabling large-scale recordings in awake, behaving animals. But these techniques generate massive, and complex data sets. Among big data platforms, Spark is ideally suited to the unique demands of scientific analytics. I will describe Thunder, an open-source library we have developed on top of Spark for analyzing large-scale spatial and temporal neural data. It's fast to run, easy to extend, and designed for interactivity and visualization.

Jeremy Freeman is a neuroscientist at HHMI Janelia Research Center (@HHMIJanelia) using computation to understand the brain. He’s passionate about brains, behavior, analytics, big data, spark, visualization, and open science.

Translate from MapReduce to Spark by Roger Ding

Roger Ding Spark has become one of the hottest technologies in Big Data and is the leading candidate to replace Hadoop MapReduce. Why? Because porting a MapReduce program to Spark will immediately results in a performance boost.

The presentation gives a brief introduction to MapReduce and Spark programming. Then a MapReduce project (processing massive amount of XML files) will be used as an example to demonstrate how to translate a MapReduce program to a Spark program.

Roger Ding is a Solutions Consultant at Cloudera, where he loves working with distributed computing technologies. He worked as a software engineer for 15 years before joining Cloudera.

SOLR Lessons Learnt by Rishi Easwaran

Rishi Easwaran Our goal is to design a highly scalable, fault tolerant, easily manageable and robust, system, to provided extremely effective and efficient search capabilities and capable of handling very high transaction volume, using an open source solution. Why we opted to use SOLR, a brief overview of our old multicore architecture, its performance, scalability, availability and pain points.

Dive into our new Multi-Tier Hybrid SOLR Cloud architecture, its performance, availability, scalability and cost benefits and lessons learnt in use of SOLR to provide mailbox search capability for AOL mail users.

Rishi Easwaran is a Principle software engineer working with the AOL mail team since 2008 and the tech lead for our existing mail search infrastructure and Re-architecture efforts to implement a Multi-tiered high availability, large scale Hybrid-SOLR Cloud solution.

Open Source Graph Analysis by Jeff Kunkle

@kunklejr kunklejr

Jeff Kunkle Lumify is a relatively new open source platform for big data analysis and visualization, designed to help organizations derive actionable insights from the large volumes of diverse data flowing through their enterprise. Utilizing popular big data tools like Hadoop, Accumulo, and Storm, it ingests and integrates many kinds of data, from unstructured text documents and structured datasets, to images and video. Several open source analytic tools (including Tika, OpenNLP, CLAVIN, OpenCV, and ElasticSearch) are used to enrich the data, increase its discoverability, and automatically uncover hidden connections. All information is stored in a secure graph database implemented on top of Accumulo to support cell-level security of all data and metadata elements. A modern, browser-based user interface enables analysts to explore and manipulate their data, discovering subtle relationships and drawing critical new insights. In addition to full-text search, geospatial mapping, and multimedia processing, Lumify features a powerful graph visualization supporting sophisticated link analysis and complex knowledge representation.

This talk will blend a high-level use case demo with a more technical presentation of Lumify's underpinnings, focusing on its use of Accumulo to implement fine-grained access control of the graph data.

Jeff Kunkle is the Director of Research and Development at Altamira Technologies, responsible for overseeing the company’s internal research and development investments.

Real-Time Inverted Search by Bryan Bende

@bbende bbende

Bryan Bende Building real-time notification systems is often limited to basic filtering and pattern matching against incoming records. Allowing users to query incoming documents using Solr's full range of capabilities is much more powerful. In our environment we needed a way to allow for tens of thousands of such query subscriptions, meaning we needed to find a way to distribute the query processing in the cloud. By creating in-memory Lucene indices from our Solr configuration, we were able to parallelize our queries across our cluster. To achieve this distribution, we wrapped the processing in a Storm topology to provide a flexible way to scale and manage our infrastructure. This presentation will describe our experiences creating this distributed, real-time inverted search notification framework.

Bryan Bende is a Senior Lead Engineer in the Strategic Innovation Group at Booz Allen Hamilton.
