Talk: The possibilities of information that can be
extracted from seemingly simple data
Speaker: Olaf Horstmann
3< OMM Solutions GmbH >
• Data Science != Big Data != Machine Learning != AI
• Data Science = Extracting information from any data
• Big Data = TeraBytes to PetaBytes of data
• Machine Learning = Training algorithms to classify or predict specific data
• AI = Training an algorithm to make correct decisions on a wide range of different situations
• Data does not deliver “truth”
• Every piece of extracted information is just an assumption/thesis

Data does not deliver “truth”

Remember
< OMM Solutions GmbH >
• Statistics have shown, that employees that used Chrome or Firefox performed better on
employment assessment metrics and stayed on longer than those who did not.
• => “Users of the Chrome and Firefox browsers are better employees.”
• The ones with “relatively feminine” names killed an average of 42 people, the ones with
“relatively male” name killed only 15 on average.
• => “Female-named hurricanes are more deadly.”
• American men 45 to 82 who skip breakfast showed a 27 percent higher risk of coronary heart
disease over a 16-year period.
• => “Skipping breakfast causes coronary heart disease”
