What Is AI?
Depends upon who you ask!
Artificial intelligence (AI) is the simulation of human cognitive
processes by machines, especially computer systems.
In practice, mathematical models are used to make decisions
based on available data, in the presence of uncertainty.

Is AI Just Hype?
• According to Gartner, 85% of AI
projects fall short of expectations
• Disconnect between expectations
and reality
• There are many problems where AI
has been proven to add substantial
value

Example Problem
A car dealership group has the following problem statement:
“We have a large potential customer
base. We would like to figure out
which of our customers are most
likely to buy a new car from us, so
that we can produce a highly
targeted marketing campaign. We
want to increase sales relative to our
current segmentation strategy.”

Assembling Customer Journeys
• How do we assign data to a customer?
• Event based data:
• Also have non-event based attributes (e.g., demographic data)
• AI model is going to learn the history and demographic factors that tend to lead to a car being purchased

Extracting Features From Data
• AI models read mathematics, not timelines!
• Feature engineering is the “art” of the AI field
• Utilize many customer journey descriptors — all can be expressed mathematically
- Number of cars previously purchased
- Length of customer tenure
- Price of any previously purchased cars
Can be used for
traditional
segmentation

How can we use the model?
Automation
• Incorporate this score into your marketing automation workflow
• Could target highest 25% of customers with one campaign
• Could then target next 25% of customers with different campaign
Augment human decision making
• Add the model score to customer profiles, so that staff can see it
• Empowers call center staff, aftersales staff, or pre-sales staff with more information about the customer

Example Problem
A higher education system has the following problem:
“We have a number of students that do not complete their 4-year degree programs. We would like to be able to predict which students are likely to drop out in a given year, so that we can provide additional support and resources.”

Assembling Student Data
• How do we assign data to a student?
• Event based data:
• Also have non-event based attributes – eg demographic data
• AI model is going to learn which event history and demographic factors tend to lead to the outcome of a person dropping out of college

How can we use the model?
Automation
• Send automatic check-in email campaign targeting students at risk of dropping out
• Could target highest 10% at risk
• Or could target all students with a score greater than, say, 75%
Augment human decision making
• Add the model score to student profiles, so that staff can see it
• Empower them to be aware of students that may be experiencing difficulties
