Corrected german credit data

[nrkarthikeyan]

The widely used german credit data (that is already available in the toolkit) apparently has coding errors, so consider including

Tasks:

• Ensure the license permits open source use.
• Verify that this dataset is appropriate for fairness tasks and subset it accordingly (removing un-necessary columns etc.).
• Ensure we have instance level records with protected attributes and outcomes.
• First create sklearn-compatible dataset (dataframe) and an appropriate "classic" dataset (second priority).
• Create a simple notebook where the dataset is consumed and simple fairness measures and computed at least.
• DO NOT download and incorporate the data, rather include a function that will do this since data is not hosted in AIF360.

I was working on Colab and also ran into this error on the German Credit notebook, aif360 gave me instructions to download two files and move them to a folder. It was solved by running this code:

%pip install wget
import wget, os

output_directory = os.path.join("/usr/local/lib/python3.8/dist-packages/aif360/data/raw/german")

german_data_url = "https://archive.ics.uci.edu/ml/machine-learning-databases/statlog/german/german.data"
german_doc_url = "https://archive.ics.uci.edu/ml/machine-learning-databases/statlog/german/german.doc"

german_data = wget.download(german_data_url, out=output_directory)
german_doc = wget.download(german_doc_url, out=output_directory)
