H2O World from an Attendee’s Perspective

Data Science is like Rome, and all roads lead to Rome. H2O WORLD is the crossroad, pulling in a confluence of math, statistics, science and computer science and incorporating all avenues of business. From the academic, research oriented models to the business and computer science analytics implementations of those ideas, H2O WORLD informs attendees on H2O’s ability to help users and customers explore their data and produce a prediction or answer a question.

I came to H2O World hoping to gain a better understanding of H2O’s software and of Data Science in general. I thoroughly enjoyed attending the sessions, following along with the demos and playing with H2O myself. Learning from the hackers and Data Scientists about the algorithms and science behind H2O and seeing the community spirit at the Hackathons was enlightening. Listening to the keynote speakers, both women, describe our data-influenced future and hearing the customer’s point of view on how H2O has impacted their work has been inspirational. I especially appreciated learning about the potential influence on scientific and medical research and social issues and H2O’s ability to influence positive change.

Curiosity led me to delve into the world of Data Science and as a person with a background of science and math, I wasn’t sure how it applied to me. Now I realize that there is virtually no discipline which cannot benefit from the methods of Data Science and that there is great power in asking the right questions and telling a good story. H2O WORLD broadened my horizons and gave me a new perspective on the role of Data Science in the world. Data science can be harnessed as force for social good where a few people from around the globe can change the world. H2O World 2015 was a great success and I truly enjoyed learning and being there.

H2O World Third Day Wrap-Up

H2O fans, we know that distance and the twin holidays of Veteran’s Day and Diwali kept many of you from attending the grand finale of H2O World, but we want to at least give you a taste of all that went on at the Computer History Museum in Mountain View. Day 3 of H2O World got off to a strong start with a massive panel on creating a culture of data-driven decision making. The panel included experts from and AT&T.


The morning continued with talks from GoPro and Board Member Michael Marks, Conor Jensen, Analytics Program Director at Zurich North America, and a very informative session on GLRM from Madeleine Udell! Before heading over to our delicious food trucks, H2O World attendees also had the opportunity to hear several keynotes. The first was an explanation of what the next generation of data products would look like from non other than data science expert Hilary Mason!


Hilary’s talk was followed by keynotes from Kaiser Permanente Vice President, Jason P Jones, who spoke about how machine learning can help with clinical decision making, and from Stanford Professor Rob Tibshirani, who spoke about using the lasso method for high dimensional supervised learning. Attendees who weren’t immediately distracted by the onset of the lunch hour had a chance to get their books signed by Hilary and Rob.


Lest you think that all the fun happened in the morning, we want to assure you that the afternoon was jam-packed as well! We hosted three panels on algorithm design and application gotchas, machine learning in financial services and machine learning in natural language processing, respectively. We also had a series of terrific talks from fellow H2O fans just like yourselves at Transamerica Corporation, Progressive, Macy’s, Nielsen Catalina Solutions, Lexalytics, Sociogramics, Altiscale, MarketShare, Machine Zone, Data Fellas, Epoch and Trendkite.

H2O World Second Day Wrap-Up

H2O fans, we didn’t think that our second day could top our first, but somehow it did! Still, although we had record attendance, we know that a lot of you aren’t here. While we can’t hope to get across all that’s happened, we do want to share some of the highlights. The morning started off with CEO Sri Ambati welcoming attendees and giving them a special sneak peek at the future roadmap of H2O.


Before even getting to lunch attendees were treated to a fascinating talk from world-renowned data science expert Monica Rogati, use case demonstrations from PayPal, Comcast, and Quora, and an explanation of Consensus Lasso from the man Sri calls “the Bob Dylan of data science,” Stanford Professor Stephen Boyd. H2O World attendees not completely entranced by our wonderful collection of food trucks got some one-on-one time to ask Monica Rogati questions during a special “fireside chat.”


At we’re focused on achieving impact, and nothing impacts people as much as their health. That’s why we were so proud to be a part of Kaiser Permanente Health Data Project Lead Taposh Dutta Roy’s afternoon talk on using data science to help battle cancer. The afternoon also featured talks from H2O users at PayPal, Capital One, AT&T, Google Analytics, GenomeDx and 6sense. A series of panels on industrial data science, the future of data science and the last mile of data science delivery were part of the afternoon’s agenda as well.


Of course, no event is complete without a party, and H2O World is no different! After a full day of listening to the world’s leading data science practitioners talk about their work, attendees were bussed over to another world at the Mos Eisley Cantina. Fortunately, none of our open source Jedi fell prey to the vile machinations of the Sith, but it was a close call!

H2O World First Day Wrap-Up

H2O fans, we wish that all of you were here, but we also know that our community is spread across the globe and not all of you could make it to H2O World. However, those of you not able to attend the conference are just as much a part of our community as those that are. While we can’t hope to convey the energy and excitement of H2O World, we can share some highlights.

In one of the day’s big surprises, AT&T data scientist Lauren Savage, who has been using H2O for just two weeks, won yesterday’s three-hour hackathon as judged by our panel of Kaggle pros. Congratulations Lauren!


The rest of the day was full of tons of great demonstrations and walkthroughs designed to help our community get the most out of their data.


New community members got an introduction to the H2O platform followed by an explanation of how to install H2O and introductions to data science, R, Python and the Flow UI. Veteran H2O users received an update on the software and an explanation of how to upgrade it. Both groups were treated to a special conversation over lunch with our Chief Architect, Arno Candel.


Silicon Valley Data Science’s Chen Huang got the the afternoon off to a great start with a talk on how to ask smarter questions to make better business decisions. Erdos, one of our two main stages, hosted a series of awesome afternoon talks on Deep Learning, GLM, Ensembles, Sparkling Water and building smart applications, plus a panel on competitive data science! Not to be outdone, the Ramanujan stage featured talks on using H2O with Databricks Cloud, GBM and Random Forest, GLRM, migrating proprietary stacks to open source H2O, Deep Learning and a panel discussion on Smart Applications!
