ADA is the marketing database
The task of ADA is to discover high revenue people from census data. This is a two-class classification problem. The raw data from the census bureau is known as the Adult database in the UCI machine-learning repository. The 14 original attributes (features) include age, workclass, education, education,
marital status, occupation, native country, etc. It contains continuous, binary and categorical features. The “prior knowledge track” has access to the original features and their identity. The “agnostic learning track” has access to a preprocessed numeric representation eliminating categorical variables, but the identity of the features is not revealed.
