+#Bank Marketing Example
+
+### Introduction
+
+This page describes how to run Mahout's SGD classifier on the [UCI Bank Marketing dataset](http://mlr.cs.umass.edu/ml/datasets/Bank+Marketing).
+The goal is to predict if the client will subscribe a term deposit offered via a phone call. The features in the dataset consist
+of information such as age, job, marital status as well as information about the last contacts from the bank.
+
+### Code & Data
+
+The bank marketing example code lives under 
+
+*mahout-examples/src/main/java/org.apache.mahout.classifier.sgd.bankmarketing*
+
+The data can be found at 
+
+*mahout-examples/src/main/resources/bank-full.csv*
+
+### Code details
+
+This eaxmple consists of 3 classes:
+
+  - BankMarketingClassificationMain
+  - TelephoneCall
+  - TelephoneCallParser
+
+When you run the main method of BankMarketingClassificationMain it parses the dataset using the TelephoneCallParser and trains
+a logistic regression model with 20 runs and 20 passes. The TelephoneCallParser uses Mahout's feature vector encoder
+to encode the features in the dataset into a vector. Afterwards the model is tested and the learning rate and AUC is printed ccuracy is printed to standard output.
