Census Income Dataset Classification

Data Science Notebook on a Classification Task

Objective

In the Jupyter Notebook included in this page, we will be using the Census Income Dataset to predict whether an individual's income exceeds $50K/yr based on census data.

The Dataset can be found here:

• https://archive.ics.uci.edu/ml/datasets/adult

The Notebook can be found here:

• https://github.com/dformoso/sklearn-classification/blob/master/Data%20Science%20Workbook%20-%20Census%20Income%20Dataset.ipynb

Companion Mindmap/Cheatsheet

This Jupyter Notepad has a companion Mindmap/Cheatsheet that lists most of the Data Science steps that can be found at the following link:

• https://github.com/dformoso/machine-learning-mindmap

Steps

In this Notebook, we'll perform:

• Feature Exploration (Uni and Bi-variate)
• Feature Imputation
• Feature Selection
• Feature Encoding
• Feature Ranking
• Machine Learning with sklearn and Tensorflow
• Random Search
• Accuracy, Precision, Recall, and f1 calculations
• ROC Curve

Setup

This Notebook has been designed to be run on top of the Jupyter Tensorflow Docker instance found in the link below:

• https://github.com/jupyter/docker-stacks/tree/master/tensorflow-notebook

If you haven't downloaded Docker at this point, please visit:

• https://www.docker.com/get-docker

Then, open a shell or terminal session and copy/paste the following:

docker run -itd \
  --restart always \
  --name jupyter \
  --hostname jupyter \
  -p 8888:8888 \
  -p 6006:6006 \
  jupyter/tensorflow-notebook:latest \
  start-notebook.sh --NotebookApp.token=''

Upon running the command, docker will automatically pull the images it needs and get the containers going for us.

Give it a minute or so for Jupyter to start, and head to the following URL: http://localhost:8888

You should now have Jupyter running. If after a minute you can't reach the URL, check that the containers are running correctly and the network has been created by typing:

### Check the containers are running
docker ps -a

Loading the Notebook

Download it from this link:

• https://github.com/dformoso/sklearn-classification/blob/master/Data%20Science%20Workbook%20-%20Census%20Income%20Dataset.ipynb

Go back to:

• http://localhost:8888, load your Notebook into Jupyter and run it. That's it!

Troubleshooting Docker

Here are a few useful commands in case something goes wrong with your docker instance:

# Restart Jupyter Docker Container
docker restart jupyter

# Stop Jupyter Docker Container
docker stop jupyter

# Remove Jupyter Docker Container
docker rm jupyter
