Beauty and Big Data [Made possible by H2O and Tableau]

Amy Wang

“A data scientist knows more statistics than a computer scientist and more computer science than a statistician.”

What is H2O?Open source in-memory prediction engineMath Platform

• Parallelized and distributed algorithms making the most use out of multithreaded systems

• GLM, Random Forest, GBM, PCA, etc

Easy to use and adoptAPI• Written in Java – perfect for Java Programmers• REST API (JSON) – drives H2O from R, python, excel

More data? Or better models? Both?Big Data• Use all of your data – model without down sampling• Run a simple GLM or a more complex GBM to find the best fit for the data• More Data + Better Models = Better Predictions
