3. Internet of Things
⢠Currently physical world
and software worlds are
detached
⢠Internet of things
promises to bridge this
â It is about sensors and
actuators everywhere
â In your fridge, in your
blanket, in your chair, in
your carpet.. Yes even in
your socks
â 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
ď§ Think about a day in your life?
â What is the best road to take?
â Would there be any bad weather?
â How to invest my money?
â How is my health?
ď§ 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?)
â Basic analytics +
visualizations
(min, max, average, histogra
m, distributions ⌠)
â Interactive drill down
⢠To explain (why)
â Data
mining, classifications, buildi
ng models, clustering
⢠To forecast
â 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
â Sensor
ID, TS, x, y, z, v, a
⢠Queries
