Damji + Reynold Xin) 6:40 - 7:25 pm Tech-Talk-1 Project Hydrogen: State-of-the-Art Deep Learning on Apache Spark 7:25 - 8:10 pm Tech-Talk-2 MLflow: Infrastructure for a Complete Machine Learning Life Cycle 8:10 - 8:30 pm Mingling & Networking Tech-Talk 1: Project Hydrogen: State-of-the-Art Deep Learning on Apache Spark Abstract: Big data and AI are joined at the hip: the best AI applications require massive amounts of constantly updated training data to build state-of-the-art models AI has always been on of the most exciting applications of big data and Apache Spark. Increasingly Spark users want to integrate Spark with distributed deep learning and machine learning frameworks built for state-of-the-art training. On the other side, increasingly DL/AI users want to handle large and complex data scenarios needed for their production pipelines. This talk introduces a new project that substantially improves the performance and fault-recovery of distributed deep learning and machine learning frameworks on Spark. We will introduce the major directions and provide progress updates, including 1) barrier execution mode for distributed DL training, 2) fast data exchange between Spark and DL frameworks, and 3) accelerator-awareness scheduling. Bio: Xiangrui Meng is an Apache Spark PMC member and a software engineer at Databricks. His main interests center around developing and implementing scalable algorithms for scientific applications.

His Ph.D. work at Stanford is on randomized algorithms for large-scale linear regression problems. Tech-Talk 2: MLflow: Infrastructure for a Complete Machine Learning Life Cycle Abstract: ML development brings many new complexities beyond the traditional software development lifecycle. Unlike in traditional software development, ML developers want to try multiple algorithms, tools and parameters to get the best results, and they need to track this information to reproduce work. In addition, developers need to use many distinct systems to productionize models. To address these problems, many companies are building custom “ML platforms” that automate this lifecycle, but even these platforms are limited to a few supported algorithms and to each company’s internal infrastructure. In this talk, we will present MLflow, a new open source project from Databricks that aims to design an open ML platform where organizations can use any ML library and development tool of their choice to reliably build and share ML applications. MLflow introduces simple abstractions to package reproducible projects, track results, and encapsulate models that can be used with many existing tools, accelerating the ML lifecycle for organizations of any size.

In this talk, Richard Garris, Principal Architect at Databricks will explain how various ML algorithms are parallelized in Apache Spark. Andrew Ng calls the algorithms the "rocket ship" and the data "the fuel that you feed machine learning" to build deep learning applications. We will start with an understanding of machine learning pipelines built using single machine algorithms including Pandas, scikit-learn, and R. Then we will discuss how Apache Spark MLlib can be used to parallelize your machine learning pipeline with Linear Regression and Random Forest. Lastly, we will discuss ways to parallelize single machine algorithms in Spark by broadcasting the data and then performing distributed feature selection, model creation or hyperparameter tuning. Bio: Richard Garris is a Principal Solutions Architect at Databricks focused on helping clients with their Advanced Analytics initiatives using Apache Spark and MLlib. He has spent 13 years working with enterprises in data management and analytics. Richard got his undergraduate degree at The Ohio State University and Masters in Software Management from CMU.

Bio: Alex Sergeev is a Deep Learning Infrastructure Engineer at Uber working on scalable Deep Learning. He received his MS. degree in Computer Science from Moscow Engineering Physics Institute. Before joining Uber, he was a Senior Software Engineer at Microsoft working on Big Data Mining. Tech-Talk 3: Apache Spark™ and MacroBase Abstract: In this talk, we present MacroBase, an analytics system we have built at Stanford University that uses Apache Spark to prioritize human attention via large-scale feature selection. In a world swamped with enormous datasets and an enormous variety of complex tools to analyze them, MacroBase specializes in one task: finding and explaining unusual or interesting trends on data as easily as possible. Specifically, it searches for correlations in large-scale datasets. For example, an app developer wondering why their app was crashing could ask MacroBase to find factors in their logs that correlate with crash behavior and explain the crashes. Alternatively, an analyst looking for trends in time series data could ask MacroBase to find changes over time. MacroBase relies on Spark and Spark-SQL to provide fast and easy-to-use analytics. Users operate MacroBase using MacroBase-SQL, an extension of SQL that introduces new operators to partition datasets and find explanations on partitions. MacroBase-SQL is built on top of Spark-SQL, with its new operators taking in and returning Spark dataframes. This means that MacroBase is fully distributed and can easily be integrated into any system already running Spark or Spark-SQL. In this talk, we will explain how we built MacroBase new operators on top of Spark and what you can do with them. Bio: Peter Kraft is a first-year graduate student at Stanford advised by Peter Bailis and Matei Zaharia. He is interested in solving problems at the intersection of systems and machine learning and in building more usable and powerful machine learning systems.

In this brief talk we will examine sharing some of the wonders of Spacy with the Java world, which still has a somewhat lackluster set of options for NLP. Bio: Holden Karau (https://www.linkedin.com/in/holdenkarau/) Tech-Talk 2: Just enough DevOps for Data Scientists (Part II) Abstract: Imagine we have Ada, our data science intern. Let's run through a very simple wordcount spark job, and find a handful of potential failure points. Dozens of failures can and should happen when running spark jobs on commodity hardware. Given the basic foundation for infrastructure-level expectations, this talk gives Ada tools to ensure her job isn’t caught dead. Once the simple example job runs reliably, with the potential to scale, our data scientist can apply the same toolset to focus on some more interesting algorithms. Turn SNAFUs into successes by anticipating and handling Infra failures gracefully. Note: this talk is a spark-focused extension of Part I, "Just Enough DevOps For Data Scientists" from Scale by The Bay 2018 https://www.youtube.com/watch?v=RqpnBl5NgW0&t=19s Bio: Anya Bida (https://www.linkedin.com/in/anyabida/) Abstract: Tech-Talk 3: Creating Beautiful and Meaningful Visualizations with Big Data Abstract: At Uber, location data is our biggest asset. How do we create data visualizations with rich location data, render a million points of events in the blink of an eye, and, most importantly, derive insights from them? In this presentation, you'll get a behind the scenes look at the tools and data visualizations we use at Uber to inform business decisions. I will walk us through an overview of the data visualization process with a case study, discuss how and why we built our own visualization tool to visualize location data in a more meaningful way. I will also show that you can create beautiful visualizations, but in order for them to be useful, you have to understand the information you are designing.

  • Bay Area Apache Spark Meetup @ Workday in San Mateo

    Happy New Year! Join us for an evening of Bay Area Apache Spark Meetup featuring tech-talks on Apache Spark (https://spark.apache.org/) at scale from Workday (https://www.workday.com/) and Databricks (https://databricks.com/). Agenda: 6:30 - 7:00 pm Mingling & Refreshments 7:00 - 7:10 pm Welcome opening remarks, announcements, acknowledgments, and introductions 7:10 - 7:50 pm Workday Prism Analytics: Unifying Interactive and Batch Data Processing Using Apache Spark 7:50 - 8:30 pm Upcoming Release Apache Spark 2.3: What’s New? 8:30 - 8:45 pm More Mingling & Networking Tech-Talk 1: Workday Prism Analytics: Unifying Interactive and Batch Data Processing Using Apache Spark. Abstract: Workday Prism Analytics enables data discovery and interactive Business Intelligence analysis for Workday customers. To prepare data for analysis, business users can clean up and transform their datasets in an interactive, modern data prep environment. Thus, Workday Prism Analytics needs to run three types of scalable data processing applications: “always on” query engine and data prep applications, and on-demand batch execution of transformation pipelines. We standardized on Apache Spark and Spark SQL for all three applications, due to its scalability, as well as, flexibility and extensibility of the Catalyst compiler. All applications share much of the compilation and execution code, except for sampling, caching, and result extraction. In this talk we will, first, introduce Workday Prism Analytics and describe its Spark-based interactive and batch data processing components. We will then describe the data prep transformations, and their compilation into Spark DataFrames, through Spark-SQL Catalyst plans, in both interactive and batch mode. We will focus on some challenges we encountered while compiling and executing complex pipelines and queries. For example, Spark SQL compilation times exceeded execution time for some low-latency queries. And compiled plans grew dangerously for data prep pipelines with multiple self-joins and self-unions. We will describe caching, sampling, and query compilation techniques that allow us to support interactive user experience. Finally, we will conclude with an overview of the open challenges that we plan to tackle in the future. Bio: Dr. Andrey Balmin is a Sr. Principal Engineer at Workday, where he is building the self-service Prism Analytics platform. His work on the foundational technology for Prism began at Platfora (which was acquired by Workday). Prior to this, he was a Research Staff Member at IBM Almaden Research Center where he focused on search and query processing of semi-structured and graph-structured data in Data Warehousing and, later, Big Data platforms.
