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

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
