AI is central to unlocking competitive advantage. However data science teams don’t have access to a consistent level of high-quality data required to build AI & ML data applications.

Instead data scientists spend 80% of their time collecting, cleaning & preparing the data for analysis rather than building AI-data applications.

During this talk Snowplow introduces the concept of data creation. Create & deploy high-quality & predictive behavioral data in real-time to Databricks.

Learn how being equipped with AI-ready data in Databricks allows data science teams to focus on building AI data applications rather than data wrangling—dramatically accelerating the pace of data projects & improving model performance & managing data governance. - How to execute more AI & data intensive applications in production using Databricks & Snowplow - How to execute on each AI & data intensive application faster thanks to pre-validated & predictive data - How data creation can solve for data governance

Databricks enables many organizations to harness the power of data; but while Databricks enables collaboration across Data Scientists and Data Engineers, there is still opportunity to begin democratizing access to domain experts. Successfully achieving this requires a rethinking of the classic analytics user interfaces, towards interactive systems with highly collaborative visual interfaces. Current visualization and workflow tools are ill-suited to bringing the full team together. I will present Northstar, a novel system we developed for Interactive Data Exploration at MIT / Brown University, now commercialized by Einblick. I will explain why Northstar required us to completely rethink the analytics stack, from the interface to the “guts,” and highlight the techniques we developed to provide a truly novel user-interface which enables creating code optional analysis over Databricks, where all user personas can collaborate together very large datasets and use complex ML operations.

One of the largest State based health exchanges in the country was looking to modernize their data warehouse (DWH) environment to support the vision that every decision to design, implement and evaluate their state-based health exchange portal is informed by timely and rigorous evidence about its consumers’ experiences. The scope of the project was to replace existing Oracle-based DWH with an analytics platform that could support a much broader range of requirements with an ability to provide unified analytics capabilities including machine learning. The modernized analytics platform comprises a cloud native data lake and DWH solution using Databricks. The solution provides significantly higher performance and elastic scalability to better handle larger and varying data volumes with a much lower cost of ownership compared to the existing solution. In this session, we will walk through the rationale behind tool selection, solution architecture, project timeline and benefits expected.

In the past, stream processing over data lakes required a lot of development efforts from data engineering teams, as Itai has shown in his talk at Spark+AI Summit 2019 (https://tinyurl.com/2s3az5td). Today, with Delta Lake and Databricks Auto Loader, this becomes a few minutes' work! Not only that, it unlocks a new set of ways to efficiently leverage your data.

Nexar, a leading provider of dynamic mapping solutions, utilizes Delta Lake and advanced features such as Auto Loader to map 150 million miles of roads a month and provide meaningful insights to cities, mobility companies, driving apps, and insurers. Nexar’s growing dataset contains trillions of images that are used to build and maintain a digital twin of the world. Nexar uses state-of-the-art technologies to detect road furniture (like road signs and traffic lights), surface markings, and road works.

In this talk, we will describe how you can efficiently ingest, process, and maintain a robust Data Lake, whether you’re a mapping solutions provider, a media measurement company, or a social media network. Topics include: * Incremental & efficient streaming over cloud storage such as S3 * Storage optimizations using Delta Lake * Supporting mutable data use-cases with Delta Lake

Talk about a challenge of building a scalable framework for data scientists and ML engineers, that could accommodate hundreds of generic or customer specific ML models, running both in streaming and batch, capable of processing 100+ million records per day from social media networks.

The goal has been archived using Spark and Delta. Our framework is built on clever usage of delta features such as change data feed, selective merge and spark structure streaming from and into delta tables. Saving the data in multiple delta tables, where the structure of these tables are reflecting the particular step in the whole flow. This brings great efficiency, as the downstream processing does very little transformations and thus even people without extensive experience of writing ML pipelines and jobs can use the framework easily. At the heart of the framework there is a series of Spark structure streaming jobs continuously evaluating rules and looking for what social media content should be processed by which model. These rules could be updated by the users anytime and the framework needs to automatically adjust the processing. In an environment like this, the ability to track the records throughout the whole process and the atomicity of operations is of utmost importance and delta tables are providing all of this out of the box.

In the talk we are going to focus on the ideas behind the framework and efficient combining of structured streaming and delta tables. Key takeaways would be exploring some of the lesser known delta table features and real-life experiences from building a ML framework solution based on scalable big data technologies, showing how capable and fast such a solution can be, even with minimal hardware resources.

From the organization of the tree of life, to the tissues and structures of living organisms: trees and graphs are a recurring data structure in biology. Given the tree-like relationships between biological entities, Knowledge Graphs are emerging as the ideal way to store and retrieve biological data.

In our first Data + AI talk (https://www.youtube.com/watch?v=Kj5bZ2afWSU), we presented the Bellman open source library (https://github.com/gsk-aiops/bellman). Bellman was developed to translate SPARQL queries into Apache Spark Dataset operations so that scientists can submit graph queries in familiar environments like Jupyter and Databricks notebooks.

In this talk, we present the new logical inferencing capabilities we've built into the Bellman OSS library. We will demonstrate how connections between biological entities that are not explicitly connected in the data are deduced from ontologies. These inferred connections are returned to the scientist to aid in the discovery of new connections with the intent on accelerating gene to disease research. To demonstrate these capabilities, we will take a deep dive into the "subclassOf" logical entailment to retrieve all subclasses of a biological entity. The performance characteristics of inference algorithms like forward and backward chaining will also be compared.

Trusted analytics and predictive data models require accurate, consistent, and contextual data. The more attributes used to fuel models, the more accurate their results. However, building comprehensive models with trusted data is not easy. Accessing data from multiple disparate sources, making spatial data consumable, and enriching models with reliable third-party data is challenging.

In response to these challenges, Precisely has developed tools to facilitate a location-enabled lakehouse on the Databricks platform, helping users get more out of their data. Come see live demos and learn how to build your own location-enabled lakehouse by:

• Organizing and managing address data and assigning a unique and persistent identifier • Enriching addresses with standard and dynamic attributes from our curated data portfolio • Analyzing enriched data to uncover relationships and create dashboard visualizations • Understanding high-level solution architecture

Profiling small molecules in human blood across global populations gives rise to a greater understanding of the varied biological pathways and processes that contribute to human health and diseases. Herein, we describe the development of a comprehensive Human Biology Database, derived from nontargeted molecular profiling of over 300,000 human blood samples from individuals across diverse backgrounds, demographics, geographical locations, lifestyles, diseases, and medication regimens, and its applications to inform drug development.

Approximately 11,000 circulating molecules have been captured and measured per sample using Sapient’s high-throughput, high-specificity rapid liquid chromatography-mass spectrometry (rLC-MS) platform. The samples come from cohorts with adjudicated clinical outcomes from prospective studies lasting 10-25 years, as well as data on individuals’ diet, nutrition, physical exercise, and mental health. Genetic information for a subset of subjects is also included and we have added microbiome sequencing data from over 150,000 human samples in diverse diseases.

An efficient data science environment is established to enable effective health insight mining across this vast database. Built on a customized AWS and Databricks “infrastructure-as-code” Terraform configuration, we employ streamlined data ETL and machine learning-based approaches for rapid rLC-MS data extraction. In mining the database, we have been able to identify circulating molecules potentially causal to disease; illuminate the impact of human exposures like diet and environment on disease development, aging, and mortality over decades of time; and support drug development efforts through identification of biomarkers of target engagement, pharmacodynamics, safety, efficacy, and more.

The application of AI algorithms in domains such as self-driving cars, facial recognition, and hiring holds great promise. At the same time, it raises legitimate concerns about AI algorithms robustness against adversarial attacks. Widespread adoption of AI algorithms where the predictions are hidden or obscured from the trained eye of the subject expert, opportunities for a malicious actor to take advantage of the AI algorithms grow considerably, necessitating the addition of adversarial robustness training and checking. To protect against and mitigate the damages caused by these malicious actors, this talk will examine how to build a pipeline that’s robust against adversarial attacks by leveraging Kubeflow Pipelines and integration with LFAI Adversarial Robustness Toolbox (ART). Additionally we will show how to test a machine learning model's adversarial robustness in production on Kubeflow Serving, by virtue of Payload logging (KNative eventing) and ART. This presentation focuses on adversarial robustness instead of fairness and bias.

Data collection, preprocessing, feature engineering are the fundamental steps in any Machine Learning Pipeline. After feature engineering, being able to parallelize training on multiple low cost machines helps to reduce cost and time both. And, then being able to train models in a distributed manner speeds up Hyperparameter Tuning. How can we unify these stages of ML Pipeline in one unified distributed training platform together? And that too on Kubernetes?

Our ML platform is completely based on Kubernetes because of its scalability and rapid bootstrapping time of resources. In this talk we will demonstrate how Lyft uses Spark on Kubernetes, Fugue (our home grown unifying compute abstraction layer) to design a holistic end to end ML Pipeline system for distributed feature engineering, training & prediction experience for our customers on our ML Platform on top of Spark on K8s. We will also do a deep dive to show how we are abstracting and hiding infrastructure complexities so that our Data Scientists and Research Scientist can focus only on the business logic for their models through simple pythonic APIs and SQL. We let the users focus on ''what to do'' and the platform takes care of ''how to do''. We will share our challenges, learning and the fun we had while implementing. Using Spark on K8s have helped us achieve large scale data processing with 90% less cost and at times bringing down processing time from 2 hours to less than 20 mins.

Many ML and big data teams in the open source community are looking to run their workloads in the cloud and they invariably face a common set of challenges such as multi-tenant cluster management, resource fairness and sharing, gang scheduling and cost-effective infrastructure operations. Kubernetes is the de-facto standard platform for running containerized applications in the cloud. However, the default resource scheduler in Kubernetes leaves more to be desired for AI scenarios when running ML/DL training workloads or large-scale data processing jobs for feature engineering.

In this talk, we will share how the community leverage and build upon Apache YuniKorn to address the unique resource scheduling needs for ML and big data teams.
