1. Beauty and Big Data
[Made possible by H2O and Tableau]
Amy Wang

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

3. 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
