3. A few words about Unity Group
Over 20 years of e-commerce experience, with hundreds of
projects for top brands in Poland and other EU countries:
4. A few words about Unity Group
• Discover some of our case studies at Stand B-11.
• Most of our clients gather lots of data (transactional, behavioural)
but do nothing with it
• Struck with limited methodological approaches to advanced data
analysis, we acquired a grant to let us apply a more scientific
perspective.
5. Our plan for today
• Why machine learning matters.
• Methodology for E-commerce.
• Machine learning methods & algorithms for marketing.
• Conclusion and suggested next steps.
6. Data-driven approach
86,4% of people will
believe any data you put
in a PowerPoint slide,
even if you just totally
made it up to prove your
point.
8. Why Machine Learning Matters
Companies that
use advanced
analytics:
Make data-
driven
decisions
Make faster
decisions
Adjust
business faster
Get better
financial
results
According to Nucleus Research, for every $1
invested in analytics you can get a return of $13.
As Forrester states, only 12% of data is leveraged
for analytics, while:
• Pattern discovery could be later used
to analyse new data
• Predictive algorithms could identify hidden
relationships beyond what human perceives
• Pattern detection can become more
comprehensible and precise as data quantity
grows
Creates a
competitive
advantage
Discovered
relationships
affect business
Gives measurable
business value
9. Advanced analysis flow
Descriptive
analytics
• Understand the
challenges
Diagnostic
analytics
• Why does it
happen?
Predictive
analytics
• What is going to
happen?
Prescriptive
• What should we do
to make it happen /
prevent its
occurrence?

16. Prediction - how it works

Analyse historical data – train a model on past cases.
Test and validate this model.
Predict the future.
17. Prediction - examples
• Purchases related to sales / special offers
• New model sales
• Product returns
• Client reactions to a discount proposal
• Probability of complaints
• Seasonal trends in product purchases
• Customer Churn
• Demand estimation (of a selected product
category)
• Price elasticity
18. Prediction - a case study
Post Christmas Sale in a fashion eCommerce – Customer Demand
Prediction.
• Training a model on historical data on participation in the Jan 2016
sale.
• Validation of the model during the Jan 2017 sale.
• Results analysis and model boosting.
• Training a model using the entire database in Dec 2017.
• Campaign based on the prediction for whole customer set.
• Following the campaign conversion.

22. CLUSTERING - RETAIL EXAMPLES
Inspired by
the RFM method
Products divided
by category & price levels
Discount & trend-driven clients
vs. brand-oriented customers
23. Clustering – a practical example
• We divide our clients into 6 groups with different discount policies
and key messages.
• Each segment is to be treated in a distinctive way.
• We don’t have to know the borders between clusters - algorithms
should define them.
32. Conclusion
• Data-driven reasoning defines thousands of hypotheses,
assessing them in terms of insights vital for your business.
• Human does not have to understand and justify those
hypotheses – they just reflect business realities.
33. • Use historical data to identify new market opportunities
• Accurately predict needs of your customers
• Feed your marketing automation with valid business hypotheses,
measure results and draw conclusions for the future
