It also takes knowledge

concepts often have blurred
and overlapping definitions.

Managers often talk
about “big data”,
which practitioners
often find vague
and inaccurate.

If a typical person can do a
mental task with less than one
second of thought, we can
probably automate it using AI
either now or in the near future.*

This is actually a lot,
if you consider
how many activities
are sequences of
1-second tasks!

AI was science fiction,
now it is our daily life.
AI is already part of:
- Siri and her “sisters”
- music and film
recommendation
services
- video games
- smart cars
- smart home devices
- customer support bots
- automated translators
and summarizers
- fraud detection
systems protecting
your bank account…
- …
The list is long and
keeps growing, fast.

AI has been mastering
increasingly complex
human abilities,
as seen with games.
The machines’ progress is fast. And accelerating.
Yes, now
machines
can outbluff
us, too!
11. The step from technology breakthroughs
to practical applications
is fast, too.
Around 2014-2015, machines caught up with us in the task of face recognition
thanks to deep learning, a new disruptive machine learning technology.

Just a few
years later, this
technology already
has applications
everywhere. It is
used in your
facebook profile…
…in security
scanners in
public places…
…and since the
iPhone 8, it lets
you unlock
your phone by
looking at it.
This is
just one
of many
examples.
13. This presentation cannot fully explain
data science / AI / machine learning:
This was just the gist of it.
Now let’s consider how this all
affects the insurance industry.
14. Data science in the insurance industry
Traditional insurance
actuaries also operate
in this intersection.
Insurers already
embraced statistics
centuries ago.

15. Data science in the insurance industry
The development
of computer science
has created many
new useful tools.

Therefore, now
insurers also hire
data scientists.
16. How does insurance work,
since always?
premiums for
risk protection
Insurance is a contract
where clients give insurers
a small fixed premium
in exchange for protection
against unwanted risks.
Insurance is often
a grudge purchase,
made only out of need.
Usually, the risk protection
is given as a payout or
other compensation
after a bad event strikes.
The insurer
invests the
premiums,
while waiting
for possible
payouts.

21. What do insurance data scientists have to say?
For my ETH thesis (here), I surveyed as many as I could in Aug / Sep 2017.
300 insurance data scientists from 40 countries took part in this survey.
What follows is a summary of trends emerging from the survey.
23. Newer, more complex
data science methods
are used more rarely, but
laggards are catching up
more or less uniformly
across the board.
Data science methods
are publicly available in
academic research, so
they alone cannot lead to
a sustainable competitive
advantage.
25. Diffusion of data formats in insurance data science / 1
The diffusion of
technologies to process
various data formats
appears to match
the typical
innovation diffusion
pattern.

27. Where do insurers go for “help” on data science?
Consultants can help
especially with setting up
or (re)organizing
data science staff
and processes.
28. Where do insurers go for “help” on data science?
Data science APIs such as:
- IBM Watson
- Google Cloud Machine Learning Engine
- Amazon Machine Learning API
- Microsoft Azure Machine Learning
- BigML
- …
provide sophisticated capabilities.
30. What can we learn from answer correlations?
Unsurprisingly,
different measures of
strength in data science are
strongly linked together.
31. What can we learn from answer correlations?
But interestingly,
they are also correlated
to an insurer’s propensity to
external linkages, i.e.:
partnering with consultants,
universities or other insurers,
plus using data science APIs.
External linkages are
a plausible cause of superior
data science capabilities.
32. When are insurance data science projects successful?
The top 2 success factors
are human factors that are
common to all projects.
33. When are insurance data science projects successful?
But the data scientists are also key:
they should have both technical
and insurance business know-how.
35. Education of insurance data scientists
Typically, they are highly educated,
but not specifically in data science (yet).
Data science programs have
just started producing graduates,
so keep an eye on this share!
36. What keeps insurance data scientists busy?
Communication and
coordination do take up
time, as in most jobs…
37. What keeps insurance data scientists busy?
...but core data science
tasks are at the top.
Therefore, insurance
is a good industry for
practicing data science.
38. Finally, how do insurance data scientists’
career trajectories look like?
They are often recruited
from other roles and,
even more often,
from other industries.
This suggests there is
a dearth of already
experienced insurance
data scientists.
39. Finally, how do insurance data scientists’
career trajectories look like?
Once in their role,
they want to remain in
data science…
…but troublingly for
insurers, not necessarily
in the insurance sector.

State of the data science arms race
among insurers
High concentration:
Just 14 big insurers
employ 51% of them.
Will data science
trigger consolidation?
Estimates based
on LinkedIn profiles
as of August 2017
49% of insurance data scientists
are spread out among 206 insurers,
with 136 of them employing only one.
41. Data science is changing insurance deeply.
As a result, the industry is in a state of flux,
where big changes are possible.
External linkages, such as collaboration with consultants,
academia or other insurers, as well as using data science APIs,
appear to help insurers increase their data science capabilities.
Data scientists in insurance are not committed to the industry, despite
being key employees and knowing the importance of domain knowledge.
Therefore, insurance company managers should:
make sure their companies adapt well to ongoing changes;
use external linkages as a tool to enhance data science capabilities;
strive to retain their experienced data scientists, as key employees.

please feel free to contact me.
I am passionate about data science, innovation, insurance and financial services.
As of March 2018, I am actively looking for a job in Zurich (CH).
