H2O.ai Machine Intelligence
Who am I?
▪ Data Scientist & Hacker @ H2O.ai▪ Lecturer in Systems Thinking, University of Illinois at Urbana-Champaign
▪ John Deere, Research, Software Product Development, High Tech Ventures▪ Lots of time dealing with data off of machines, equipment, satellites, radar,
hand sampled, and on.▪ Geospatial and temporal / time series data almost all from sensors.▪ Previously at startups and consulting (Red Sky Interactive, Nuforia,
NetExplorer, Perot Systems, a few of my own)
▪ Systems Design & Management MIT▪ Physics Georgia Tech

H2O.ai Machine Intelligence
The data is going to be huge, so get ready

H2O.ai Machine Intelligence
Wow, how big is a brontobyte?

H2O.ai Machine Intelligence
This much data will require a fast OODA loopMuch of these models will then be used in control systems

Key take aways for modeling the sensored IoT
• Some sort of signal processing is usually helpful, but can introduce bias• Smoothers, filters, frequency domain, interpolation, LOWESS, ... ,
aka feature engineering or post-processing• Knowing a little about the physics of the system will be helpful here
• Validation strategy is important• Easy to memorize due to autocorrelation
• Sometimes the simplest things work• Treat each observation independently; Use time, location, as data elements
• Uncertainty is the name of the game• Methods that will report out probabilities are often required (not shown here)
• The data can be big, get ready, it'll be a great ride• Scalable tools like H2O will help you model the coming brontobytes of data
