The Internet of Things is about data, not things. Some forecasts that by 2018 the number of connect things will exceed the combined number of personal computers, smartphones, and tablets. Each ’thing’ can produce a tremendous stream of data from sensors and other sources. This presentation will discuss progress, examples, challenges, and opportunities with machine learning for the IoT. A short presentation will be done on some recent applications of ML (using H2O) to the domains of machine prognostics / health management (PHM) and agriculture. Presented by Hank Roark, Data Scientist / Hacker at H2O.ai.

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

The data is going to be huge, so get ready

Wow, how big is a brontobyte?

This much data will require a fast OODA loop
Much 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
