KEYNOTE: Healthcare - The Final Frontier
Nathan Salmon - Chief Architect for Ember
9:40 AM - 10:10 AM 

Consider this:

  • Nearly 50% of cancer patients are diagnosed too late

  • Medical errors are the third leading cause of death in the U.S. after heart disease and cancer

  • It takes an average of 7.6 years in the United States to uncover a rare disease diagnosis


In the Data Age, Digital Transformation has permeated nearly every industry, from retail and finance to cyber security. This, along with modern advances in machine learning and artificial intelligence, has led to the realization of astounding efficiencies, insight, and automation that were thought to be impossible even 5 to 10 years ago. However, despite being arguably the most globally impactful and altruistic cause, for one reason or another, healthcare lags the pack.


In this talk we’ll survey the challenges facing the healthcare industry’s adoption of a modern data-driven culture, and how other similarly-regulated industries are already solving these problems today. From precision and genomic medicine to population health, we’ll discuss the great opportunities and novel use cases that can literally change lives, and what we can do practically with current technology in healthcare to boldly go where most industries have gone before.



Modern Data  Architecture with Cloud Native Technologies
Ugur Tigli - Chief Technical Officer
10:20 AM - 11:00 AM 

Modern analytics workloads need to run at the speed of business. As applications generate more data at rates faster than before, storage infrastructure needs to catch up with the analytics platforms. Only then businesses can analyse the data and respond quickly to changing market needs.


Private AWS S3 compatible cloud object storage solutions, such as Minio, allow organizations to leverage object storage as the standard storage platform, while also offering the necessary speed and agility to directly use data from object storage and feed it to Spark like platforms in a cloud native framework.


This cuts out extra data analysis stages like Extract, Transform and Load (ETL), and simplifies over all data pipeline. Streamlined data flow makes maintenance easier and cuts infrastructure and manpower costs.


This session will focus on benefits of deploying Minio Object Storage services in a private cloud to support Spark and AI use cases. We will walk through how private cloud object storage could help in storing massive amounts of data using de facto interfaces and help optimize data analysis pipeline using Spark.

A Discussion of Model Explanation Tools with Practical Recommendations
Patrick Hall - Senior Director of Product
10:20 AM - 11:00 AM 
100 D/E

This presentation is a technical discussion of several explanatory methods that go beyond the error measurements and plots traditionally used to assess machine learning models. The approaches, decision tree surrogate models, individual conditional expectation (ICE) plots, local interpretable model-agnostic explanations (LIME), partial dependence plots, and Shapley explanations, vary in terms of scope, fidelity, and suitable application domain. Along with descriptions of these methods, a few practical recommendations are also presented. Materials for this presentation are available online: For audience members who would prefer a more hands-on experience, consider attending the tutorial session: Practical Techniques for Interpretable Machine Learning.

Data Modeling Considerations for State Management of Spark Structure Streaming
Ted Malaska - Director of Enterprise Architecture
11:05 AM - 11:45 AM

As we move from a world of Batch to Streaming, the concept of streams as tables and tables as stream is emerging. In this session we will do a deep dive into the phase.  First, going into the different statement management strategies available in Spark Structured Streaming.

This will include hot topics like:

  • Sessionization

  • Customer 360

  • Triggering & Evicting

  • Checkpointing and addressing the idea of micro batching  


Each example will be accompanied by real workable examples that will be posted on GitHub so you can try them at home.


Second, the session will close with a vision for a data ecosystem that expectidates the progression from research batch to NRT actionable value.

AI assisted Merchandising: Driven by Personalized Recommendations, Powered by Spark
Charmee Patel - Data & Analytics Architect
Vijay Chakilam Data & Analytics Lead
11:05 AM - 11:45 AM 
100 D/E

In the age of information overload and ample choices, many companies are keenly aware of the competitive advantage of better recommendations and are investing to go beyond the most commonly used recommendation algorithms like collaborative and content filtering and their various hybrids. The next frontier in recommender systems is real-time contextual and personalized recommendations where the current user context, as defined by their online and offline experiences, is considered in making personalized recommendations. In this talk, we discuss how we have built a modern recommender systems by: 1) Considering clickstream data; 2) Leveraging advanced techniques to create latent features to reduce dimensionality; and 3) Using Apache Spark to support scalable batch and streaming operations.

KEYNOTE: Introducing MLflow: Infrastructure for a Complete Machine Learning Life Cycle
Elena Boiarskaia - Senior Technical Solutions Engineer
2:1o PM - 2:40 PM 

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 session, we introduce 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.


With a short demo you see a complete ML model life-cycle example, you will walk away with:

  • MLflow concepts and abstractions for models, experiments, and projects

  • How to get started with MLFlow

  • Using tracking APIs during model training

  • Using MLflow UI to visually compare and contrast experimental runs with different tuning parameters and evaluate metrics
