BIGDATA

“Scale your data mountain”

“The data avalanche”“Data is

the new

oil”

“The data tsunami”

So why do so many projects fail?

“During 2015, only 15% of Fortune 500 organizations were able to

exploit big data for competitive advantage” – Gartner

“Data maturity of companies is very disparate, and

the most advanced of them start doubting.”

– Christophe Bourguignat

“75 % have invested in Big Data, but only 10% have

projects in production.”

Companies face disillusions. They start asking

questions: I know how much it costs, but how much

do I earn? What is my return on investment?

Machine learning and data science have ( just) reached “peak hype”

• You can’t predict the future.

I want to put this GBM into production,

though some steps are done using R and SAS

Anyone know what this XGBoost thing is?Why aren’t we

deployed yet? We have all this data, why can’t

we find interesting customers?

• Learn each other’s language

• Think with your business hat

• Teach semantics (why a shorter lead list is not easier

to produce)

• Convert hard problems into simpler ones

• Use examples, methaphors, analogies

• Show them and show them often

• IT and data science can live together

“Not everything that counts can be counted…

and not everything that can be counted counts”MEA-

• Show before and after

• “When are you happy?”

• Accept failures

• Manual measuring can be a good thing• Hard to automate subjective feelings…

“No one ever got fired for installing Hadoop on a

cluster… right?”

tools/libraries/… in an hour than a procurement

• Let them (us) own the data

• Ship fast, ship often

• Focus on format and storage standards, not on

technology:

“Can I get information on X for months A and B with only those

columns that changed?”

... “Can I get it myself?”

• Where’s your golden data set?

• HDFS?

• What about HFD5, or Kudo?

• Do we even have unstructured data?

• Do we know what to do with it?

• V’s of Big Data – yeah right!

• BigSQL, or Hive, or Slurp?

• Cloudera, Hortonworks, Teradata, Oracle, I want Hadoop!?

• What do you mean we need H2O on top of Spark on top of Hadoop? We just installed X

• We did these things before… they weren’t hard then

• Versioning

• Collaboration

• Scalable execution

• Multiple language support

• Multiple kernel support

• Monitoring

• Scheduling

• Acyclic dependency graphs

• Quite different from playing in a notebook• Vendors are starting to help out

• SAS, SPSS, Domino Data Labs, sense.io, ScienceOps

<-> Jupyter, Rodeo, Your 3GB PIP packages

• Not familiar both to most data scientists (too messy) and IT shops (too

unfamiliar)

• Can new hires get set up in the environment to run analyses on their first day?

• Can data scientists utilize the latest tools/packages without help from IT?

• Can data scientists use on-demand and scalable compute resources without help from IT/dev ops?

• Can data scientists find and reproduce past experiments and results, using the original code, data, parameters, and software versions?

• Does collaboration happen through a system other than email or copying files?

• Can predictive models be deployed to production without custom engineering or infrastructure work?

• Is there a single place to search for past research and reusable data sets, code, etc?

• Do your data scientists use the best tools money can buy?

Garbage in…QUALITY

“This model is gonna be great!”

Sometimes they are…QUALITY

• Really: everyone has bad data• But: more “bad” means more time

• Do make sure to get a continuous source

to the “bad” data

• Survey: 50+ banks participating world-wide• Most banks indicated that between 10–20 percent of their data suffer from data

quality problems

• Manual data entry is one of the key problems

• Diversity of data sources and consistent corporate wide data representation the

main challenges for data quality

• Regulatory compliance is the key motive to improve data quality

Oh boy…

• Datensparsamkeit

• Cookie law

• Basel II / III

• Who knows where the cloud is anyways?

• EU directives outdated

• “It’s all on Facebook anyway”
