Agenda: Predictive & IIoT
• Why in the limelight?!
• Now. is it new-and-unique or sum-of-parts!
• Next. will it be new-and-unique or sum-of-parts!

Challenge : Data-Insight Gap
• There is no ‘free lunch’ : better predictions need more data!
• Ways to narrow the gap!
• (Volume, Velocity) faster, fatter path from data to decisioning!
• (Variability) clever ways to clean data at scale!
• Match best algorithm for the data at hand!
data maturity!

The ‘gap’ is not unique to IIoT. The reasons for it are ..!

IIoT vs Consumer Web : Same gap, different reasons
Consumer IIoT
Capture Hard!(consumers don’t cooperate)!
Easy!(‘things’ always
cooperate - for a price)!
Sanitization Medium!(simpler data types)!
Hard!(gnarlier data types)!
Modeling & Integration
Easy!(e.g. eyeballs, dwell time)!
Hard!(complex data models)!

Option1. data goes to decisioning !Fatter, faster pipes!
Continuous flow!
Option 2. decisioning goes to data !Intelligent Edge !Periodic updates!

Edges make IIoT Faster
GE Blog - Edge: A Door to the Data Kingdom!
➡ Edges distribute predictive services (cloud vs edge)!➡ policy vs behavior !➡ long-term vs real-time !
➡ architectures for flexible (re)distribution of predictive decision logic?!

Edges make IIoT Faster and Cheaper
➡ Edges distribute predictive services (cloud vs edge)!➡ policy vs behavior !➡ long-term vs real-time!
➡ how will predictive decision logic move to where the data is?!

Slow lakes to fast streams
• Now. Transition from data lakes to data streams!
‣ 30-100x speed up : streams over lakes!
‣ needed to deal with real-time IIoT traffic!
‣ lambda architectures balance prediction speed and accuracy!

2-Tiered Machine Learning for IIoT
• Intelligent IoT data cleansing layer (e.g. Bitstew) - Machine Learning turns dirty data into clean data!
• low-level data cleaning pushed to the edge!
• semantic integration between data sources in the cloud!
• Predictive Layer - Machine Learning turns clean data into clean insights!
interfaces between cleansing & prediction? !
