Modernizing to a Cloud Data ArchitectureDatabricks
Organizations with on-premises Hadoop infrastructure are bogged down by system complexity, unscalable infrastructure, and the increasing burden on DevOps to manage legacy architectures. Costs and resource utilization continue to go up while innovation has flatlined. In this session, you will learn why, now more than ever, enterprises are looking for cloud alternatives to Hadoop and are migrating off of the architecture in large numbers. You will also learn how elastic compute models’ benefits help one customer scale their analytics and AI workloads and best practices from their experience on a successful migration of their data and workloads to the cloud.
Want to see a high-level overview of the products in the Microsoft data platform portfolio in Azure? I’ll cover products in the categories of OLTP, OLAP, data warehouse, storage, data transport, data prep, data lake, IaaS, PaaS, SMP/MPP, NoSQL, Hadoop, open source, reporting, machine learning, and AI. It’s a lot to digest but I’ll categorize the products and discuss their use cases to help you narrow down the best products for the solution you want to build.
In this session, we introduce AWS Glue, provide an overview of its components, and share how you can use AWS Glue to automate discovering your data, cataloging it, and preparing it for analysis.

Unified Big Data Processing with Apache Spark (QCON 2014)Databricks
While early big data systems, such as MapReduce, focused on batch processing, the demands on these systems have quickly grown. Users quickly needed to run (1) more interactive ad-hoc queries, (2) sophisticated multi-pass algorithms (e.g. machine learning), and (3) real-time stream processing. The result has been an explosion of specialized systems to tackle these new workloads. Unfortunately, this means more systems to learn, manage, and stitch together into pipelines. Spark is unique in taking a step back and trying to provide a *unified* post-MapReduce programming model that tackles all these workloads. By generalizing MapReduce to support fast data sharing and low-latency jobs, we achieve best-in-class performance in a variety of workloads, while providing a simple programming model that lets users easily and efficiently combine them.
Today, Spark is the most active open source project in big data, with high activity in both the core engine and a growing array of standard libraries built on top (e.g. machine learning, stream processing, SQL). I'm going to talk about the latest developments in Spark and show examples of how it can combine processing algorithms to build rich data pipelines in just a few lines of code.
Talk by Databricks CTO and Apache Spark creator Matei Zaharia at QCON San Francisco 2014.
At wetter.com we build analytical B2B data products and heavily use Spark and AWS technologies for data processing and analytics. I explain why we moved from AWS EMR to Databricks and Delta and share our experiences from different angles like architecture, application logic and user experience. We will look how security, cluster configuration, resource consumption and workflow changed by using Databricks clusters as well as how using Delta tables simplified our application logic and data operations.
This presentation focuses on the value proposition for Azure Databricks for Data Science. First, the talk includes an overview of the merits of Azure Databricks and Spark. Second, the talk includes demos of data science on Azure Databricks. Finally, the presentation includes some ideas for data science production.

Instead of manually setting up a Spark Infrastructure, worrying about scaling out and scaling down, managing data stored in a shared memory, and taking care of it's back up too, Databrick provides an alternative. Databricks allows the developers to worry about the code that will run on the Spark cluster, and not the cluster's infrastructure. It creates an envelope around Spark, abstracting all the Infrastructure requirements from the Developer. Not only the cluster, Databricks also manages the shared FileSystem that will be used for storing the data. It provides notebooks that can be used to run spark code interactively, in multiple languages. A user can also leverage Databrick's Spark-submit job feature.
In this session we will delve into the world of Azure Databricks and analyze why it is becoming a tool for data Scientist and/or fundamental data Engineer in conjunction with Azure services

Data Engineering A Deep Dive into DatabricksKnoldus Inc.
During this session, you'll gain a comprehensive understanding of Databricks' capabilities for efficiently processing and managing data, with a focus on Apache Spark for data transformation. We'll cover data ingestion methods, storage, orchestration, and best practices to ensure your data engineering workflows are optimized for success.
These are the slides for my talk "An intro to Azure Data Lake" at Azure Lowlands 2019. The session was held on Friday January 25th from 14:20 - 15:05 in room Santander.
Azure Databricks (For Data Analytics).pptxKnoldus Inc.
Azure Databricks is a cloud-based platform that simplifies big data analytics. It's essential because it streamlines data processing, analysis, and visualization, crucial for deriving insights from vast datasets. It works by managing Spark clusters automatically, enabling users to focus on analysis. Different data bricks, like Azure Blob Storage, can be integrated seamlessly. Implementing Azure Databricks with Blob Storage involves creating a workspace, configuring Blob Storage, generating access keys, mounting Blob Storage as a filesystem, and utilizing data processing capabilities within Databricks notebooks. This integration enhances data accessibility and analysis, facilitating informed decision-making.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
