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

IoT Data Comes From Lots of Places, Much of it from Sensors
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

Many more tips and tricks

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, ... , feature
engineering
• 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 bronobytes of data
