21. What is Data Science?
Data Science is a holistic view
on the
lifecycle of heterogenous data
to infer
domain specific knowledge
generating competitive business advantages.
Dr. Marcel Blatter

22. Where is the “Science”
in Data Science?
If you have to label something with “science”, then
the “science” is probably only in the label.
Dr. Marcel Blatter

23. Where is the “Science”
in Data Science?
p(y|x)p(x) Just using machine learning
p(x|y) =
p(y) methods is not
X
p(y) = p(y, x) science.
x
Dr. Marcel Blatter

24. Where is the “Science”
in Data Science?
Just hunting for correlations
is not science.
Dr. Marcel Blatter

25. Where is the “Science”
in Data Science?
We need at least the exploratory approach of
science.
This means:
learning to ask the right questions and giving
answers with explanatory power.
Dr. Marcel Blatter

26. Why should companies care?
Data science is not just about reporting something.
It’s about exploration and invention.
Dr. Marcel Blatter

27. Why should companies care?
New discoveries can turn into products
or competitive advantages.
Dr. Marcel Blatter

28. Thank you for you attention.
