- Managing Globally Distributed Data for Deep Learning using TensorFlow on YARN
The benefits of large datasets for deep learning are well known. But what if the source of this data is globally distributed? Jagane Sundar shares a system for replicating data across geographically distributed data centers, discusses the benefits of consistently replicating data that is used by TensorFlow for training, and explores the advantages of using a Paxos-based distributed coordination algorithm for replication. Jagane then details the resultant unique capability to maintain consistent writable copies of the data in multiple data centers. Speaker: Jagane Sundar is the CTO at WANdisco. Jagane has extensive big data, cloud, virtualization, and networking experience. He joined WANdisco through its acquisition of AltoStor, a Hadoop-as-a-service platform company. Previously, Jagane was founder and CEO of AltoScale, a Hadoop- and HBase-as-a-platform company acquired by VertiCloud. His experience with Hadoop began as director of Hadoop performance and operability at Yahoo. Jagane’s accomplishments include creating Livebackup, an open source project for KVM VM backup, developing a user mode TCP stack for Precision I/O, developing the NFS and PPP clients and parts of the TCP stack for JavaOS for Sun Microsystems, and creating and selling a 32-bit VxD-based TCP stack for Windows 3.1 to NCD Corporation for inclusion in PC-Xware. Jagane is currently a member of the technical advisory board of VertiCloud. He holds a BE in electronics and communications engineering from Anna University. WANdisco will be giving away 3 Ipad Airs (the new model!) at the meetup.To enter the drawing, take this 3-question quiz https://forms.gle/op8PChvjuz2NXfSK6 by 12pm PST on Wed, 27 Mar and show up at the meetup for the drawing.
- The Feature Store: the missing API between Data Engineering and Data Science?
This is a crosspost from Bay Area AI, please register at https://www.meetup.com/bay-area-ai/events/258164070 Machine Learning (ML) pipelines are the key building block for productionizing ML code. However, pipelines are often developed as "silos" - features tend not to be easily re-used across pipelines or even within the same pipeline. Silos lead to duplication, unnecessarily re-implementing features and in the worst case correctness problems, if, for example, the features used for training and serving have inconsistent implementations. The Feature Store solves the problem of siloed and ad-hoc machine learning pipelines, by providing a data layer where feature engineering can be separated from the usage of features to generate training data. That is, the Feature Store should provide a clean API separating Data Engineering from Data Science. In this talk, we will introduce the world's first open-source Feature Store, built on Hopsworks, Apache Spark, and Apache Hive and targeting both TensorFlow/Keras and PyTorch. We will show how ML pipelines can be programmed, end-to-end, in Python, and the role of the Feature Store as a natural interface between Data Engineers and Data Scientists. In an end-to-end pipeline, we will show how the Feature Store works, and how you can write end-to-end ML pipelines in Python only (if you so choose). Speaker Bio: Jim Dowling is the CEO of Logical Clocks AB, as well as an Associate Professor at KTH Royal Institute of Technology in Stockholm. He is the lead architect of Hops, the world's most fastest and most scalable Hadoop distribution and first Hadoop platform with support for GPUs as a resource. He is a regular speaker at AI industry conferences, and blogs at O'Reilly on AI.

- Aggregations and knowledge extraction from social data: challenges and lessons
This is a crosspost from the Bay Area AI -- register there to attend! https://www.meetup.com/bay-area-ai/events/257791863/ This talk is about the construction of new data assets from social media using techniques drawn from the areas of information retrieval, machine learning, graphs, and social networks. I’ll describe three projects based on Twitter and Foursquare data sets that use social data in different ways to help users in information seeking scenarios. The first one, a recommender system for recreational queries using location-based social networks. The second project, a social knowledge graph derived from Twitter with the goal of discovering relationships between people, links, and topics. And the third one, an application for archiving and Wikification of stories. Omar Alonso is a Principal Applied Scientist with Microsoft where he works on the intersection of information retrieval, social data, human computation, and knowledge graph generation. He is the co-chair of the Human Computation and Crowdsourcing track at WWW'19 and on the organizing committee for HCOMP'19.
- Scale By the Bay 2018
Dear Friends — we are proud to announce the program of Scale By the Bay 2018, our sixth year of the flagship, and by now iconic, independent developer conference By the Bay. (Tl;dr: get your spot at http://scale.bythebay.io while supplies last, and especially when Early Bird is in effect until August 31.) The conference follows the established three-day, three track structure, hosted for the third year in a row by Twitter HQ in its wonderful modern building, with all of its spacious tracks, community spaces, cozy booths, and the commons area where so many connections are made during the hallway track. This year, Martin Odersky, the creator of Scala, opens the main conference on November 15. Neha Narkhede, the co-creator of Kafka and cofounder of Confluent, is keynoting the day 2. The three tracks are — Functional and Thoughtful Programming — Reactive Microservices and Streaming Architectures — End-to-end Data Pipelines all the way up to Machine Learning and AI The 100 sessions include technology leaders such as Twitter, IBM, Microsoft, Salesforce, Fauna, DataStax, Databricks, Confluent, Credit Karma, Sumo Logic, GoPro, Buoyant, Workday, Zignal Labs, and many more. We cover your tools with JetBrains, your shopping with Best Buy and Target, your vacations with HomeAway, your listening with Spotify, your viewing with Netflix, your reading with Medium, and your banking with JP Morgan Chase. The list goes on and on and on — we have the most of the advanced stacks and approaches employed by the best that Silicon Valley offers to the world at scale, shared as best practices, with code, yours to learn, take home, and build upon. Our speakers span the whole spectrum from the first-time presenters with leading companies to veterans of SBTB going all the way back to 2013, evolving their craft before our eyes. You can follow their progress by watching their previous talks on http://functional.tv and the photos of the past conferences at https://meetup.bythebay.photo/Conferences/Scale-By-the-Bay The three panels, closing each day, are: — Thoughtful Software Engineering — Data Engineering for AI, and — Cloud, Edge, and Silver Lining. Each day begins with a hot breakfast, that begins an uninterruptible supply of Philz coffee through the whole day, and lunch is provided. On the first two days, the closing panels are followed by our signature happy hours, with great drinks, food, and conversation. The hallway tracks are legendary. SBTB is famous for its bespoke, all-day, build-yourself-a-company training. This year, we double it. Cliff Click, the legend of software engineering, is teaching a full day Advanced Software Engineering workshop on 11/13, followed by Ryan Knight, now of Fauna, leading cloud-native data pipelines on 11/14. The workshops are limited by 80 participants each. As last year, we’ll plan an unconference track for those who want to share their ideas in an intimate setting for joint brainstorming. The only thing moderate about SBTB is its size — we cap at 600 attendees to preserve the immediate and direct nature of the communication that happens, sparks that fly, and serendipity that always occurs. We are always sold out by the time the conference begins in November — so reserve your seat early at http://scale.bythebay.io! And enjoy the Early Bird that is in effect until August 31.
