• Want to estimate some value: target variable
– Can be category (ELEC/GAS) or number (e.g., kWh)
– Category – classification; number – regression
» Have something we know about each instance that might
help us estimate: features
• Know the answer for some instances: labeled training set
Standard machine learning setting
The function you use doesn’t really matter
The function we used earlier was logistic regression
Others include SVM, nearest neighbor, neural networks

Target the right people with utility programs
Target likely participants
• Some customers are more likely to
participate in any program
Target specific customers for
certain programs
• Different types of customers are better
fitted for different utility programs,
indicated by their propensity
• Target low propensity customers for
simple programs, and high propensity
customers for more involved customers
High Propensity Program
Low Propensity Program
