The data is related to direct marketing campaigns of a Portuguese banking institution.

The marketing campaigns were based on phone calls. Often, more than one contact with the same client was required, in order to access if the product (bank term deposit) would be (or not) subscribed.

There are two datasets:

1) bank-full.csv with all examples, ordered by date (May 2008 to November 2010). 2) bank.csv with 10% of the examples (4521), randomly selected from bank-full.csv

The smallest dataset is provided to test more computationally demanding machine learning algorithms (e.g. SVM).

Goal: The classification goal is to predict if the client will subscribe to a term deposit (variable y).

Number of Instances: 45211 for bank-full.csv (4521 for bank.csv)

Number of Attributes: 16 + output attribute.
