Maschine Learning – An Example
Everybody uses machine
learning today – in your
photo app it identifies
faces and persons on
your images.

Cheap Compute Power
and Parallel Processing
“2.5 Exabytes of data are
produced every day – that’s
90 years of HD videos.”
“90 % of the worlds data
today has been created in the
last 2 years alone.”
March 2015, DN Capital
Availability of Data R&D on Algorithms
Machine Learning – Why is ML so HOT?
Three combining trends: big
data, massive compute
power, and better algorithms.

Intelligence
Machine Learning
Neural Networks
Deep Learning
There is a lot of buzz around
some related terms. Often
confused, are they neither
separted nor the same.

The Principle: Recognizing Activities
Learning dependent patterns of movements
Different sports, different
movements –algorithms
learns characteristic patterns
in sensor data.

Learned classification
The Principle: Recognizing Activities
Combination of algorithms clusters the different raw data and connects it to
different activties. Doing that, new and previously unknown incoming data can be
appropriately classified.

Use Cases for Machine Learning
Manufacturing
• Predictive Maintenance
• Warranty reserve estimation
• Propensity to buy
• Demand forecasting
• Telematics
Healthcare
• Alerts and diagnostics from real-
time patient data
• Risk stratification
• Proactive health management
Retail
• Predictive inventory planning
• Recommendation engines
• Upsell and cross-channel
marketing
• Market segmentation
• ROI and customer value
Travel and Hospitality
• Aircraft scheduling
• Dynamic pricing
• Consumer feedback (social
media analysis)
• Customer complaint resolution
Energy
• Smart grid management
• Power usage analytics
• Energy demand and supply
optimization
• Seismic data analysis
• Carbon emission and trading

Financial Services
• Risk analytics and regulation
• Customer segmentation
• Cross-/Up-Sell
• Campaign management
• Credit worthiness evaluation
More than a third of early
movers also saw gains in
bottom-line performance using
machine-reengineering
to slash 15% to 70%
of costs from certain
processes.
Business
processes in
every industry
will be affected.

Example: Predict Maintenance of Computer Tomographs
Thousands of devices,
Tens of thousands event codes per day,
sensor data
1,000s of predictive models
Challenge: Predict failures of components
5 to 10 days in advance
>70% precision
and <20% false positives
Impact on operative processes
Real applications tend
to become complex.
It‘s not only 1 model /
algorithm!

Analytics needs two things: building
best models AND bringing them
into production. Automation
needed due to complexity / scale.

Summary & Next Steps
Collect & explore data, learn patterns, and automate decisions.
Data Science PLUS lines of
businesses
Only the integration in new
processes will lead to
business value. Everyone
needs to understand the
possibilities of ML.
Machine Learning
improves analytics
Machine learning is an
essential part
of Advanced Analytics –
and every corporate
strategy.
Operationalization requires
discovery and action
Automation and
integration are more
important than algorithms
Machine Learning
This e-book provides a
primer on these innovative
techniques as well as 10 best
practices and a checklist for
machine learning readiness.
