3. Internet of Things
• Currently physical world
and software worlds are
detached
• Internet of things
promises to bridge this
– It is about sensors and
actuators everywhere
– In your fridge, in your
blanket, in your chair, in
your carpet.. Yes even in
your socks
– Google IO pressure mats
4. If a tree falls in a
forest and no one
is around to hear
it, does it make a
sound?
5. A day in your life
Think about a day in your life?
– What is the best road to take?
– Would there be any bad weather?
– How to invest my money?
– How is my health?
There are many decisions that
you can do better if only you can
access the data and process
them.

6. Analytics
• Useful information
about your
organization/
system
• E.g. Min, Max,
mean, historical
trends, grouping
etc.
• Technical term is
KPIs (Key
performance
Indicators )
7. Real Time Analytics
• Most first usecases were of
batch processing, which take
minutes if not hours to run
• Many insights you rather have
sooner

8. Making Sense of Data
• To know (what happened?)
– Basic analytics +
visualizations
(min, max, average, histogra
m, distributions … )
– Interactive drill down
• To explain (why)
– Data
mining, classifications, buildi
ng models, clustering
• To forecast
– Neural networks, decision
12. Usecase 1: Travel
• Collect traffic data +
transportation data from
sensors
• Build a model (e.g. Car
Following Models)
• Predict the traffic ..
Possibilities on congestion
• E.g. divert traffic, adjust
troll, adjust traffic lights
13. Usecase 2: Football Game
• Event Processing
challenge
• Real football
game, sensors in
player shoes + ball
• Events in 15k Hz
• Event format
– Sensor
ID, TS, x, y, z, v, a
• Queries
