Presnetated to the Digital Catapult (@DigiCatapult), this presentation aims to introduce Big Data Science and create a sense of realisation to adopt the technology.

1. BIG DATA SCIENCE
“The price of light is far less than the cost of darkness”
Chandan Rajah [ @ChandanRajah ]

2. BENEFITS OF BIG DATA
COST SPEED
AGILITY CAPABILITY

3. Steps to the EPIPHANY

WHAT WHY
DEMO

4. What is Big Data ?
Big Data ≠ Data Volume
Big Data = Crude Oil
Think of data like ‘Crude Oil’
Big Data is about extracting ‘crude oil’; transporting it in ‘pipelines’; storing it in ‘mega tanks’

5. What is Data Science ?
Data Science ≠ Statistical Analysis
Data Science = Oil Refinery
Data science is about ‘treating’ data; applying ‘science’ to the data;
Refine the data ‘results’; and combine to form ‘insight’

6. Knowns, Unknowns & DIKUW FTW!
known knowns
we know we know
known unknowns
we know we don’t know
unknown unknowns
we don’t know we don’t know

raw what how to why when
numbers description experience cause & effect prediction
letters context tested proven what’s best
symbols relationship instruction
signals reports programs models

known knowns
known unknowns unknown unknowns

7. Data Analytics to Data Discovery ?
data you know
data you don’t know

DATA MODELLING
Y  F( X, random noise, parameters)
ALGORITHMIC MODELLING
Y  [ BLACK BOX ]  X

8. DIVIDE
SCATTER
Split Data in Block
Replicate and Store
Petabytes of Resilience
CONQUER
EXPLORE
1000s of Parallel Threads
Explore Every Path
Machine Learning
INSIGHT
GATHER
Real Time Action
Periodic Dashboards
Iterative Evolution
What is the Big Idea ?

10. Conquer = MapReduce

11. Insight = Functional Paradigm

13. Why is Big Data needed ?
VOLUME VELOCITY VARIETY
Exponential growth; 2x in 2 yrs
PB (1000 TB) is now common
Event streams; never at rest
640k GB per internet minute
100s of data sources
85% not in a table

14. Where in the Value Chain ?
Generation Transport Knowledge Output Value
BIG DATA SCIENCE
Straddles all four Challenge Areas
