+## Introduction
+
+FlinkML is designed to make learning from your data a straight-forward
process, abstracting away
+the complexities that usually come with having to deal with big data
learning tasks. In this
+quick-start guide we will show just how easy it is to solve a simple
supervised learning problem
+using FlinkML. But first some basics, feel free to skip the next few lines
if you're already
+familiar with Machine Learning (ML)
+
+As defined by Murphy [cite ML-APP] ML deals with detecting patterns in
data, and using those
+learned patterns to make predictions about the future. We can categorize
most ML algorithms into
+two major categories: Supervised and Unsupervised Learning.
+
+* Supervised Learning deals with learning a function (mapping) from a set
of inputs
+(predictors) to a set of outputs. The learning is done using a __training
set__ of (input,

It's more of a statistics terminology, see
[synonyms](http://en.wikipedia.org/wiki/Dependent_and_independent_variables#Statistics_synonyms).
In ML features is more common so I will change it to that.
