# Compas |
|
The [Compas dataset](https://github.com/propublica/compas-analysis) for recidivism prediction. |
|
Dataset known to have racial bias issues, check this [Propublica article](https://www.propublica.org/article/machine-bias-risk-assessments-in-criminal-sentencing) on the topic. |

# Configurations and tasks |
|
| **Configuration** | **Task** | Description | |
|
|----------------------------------|---------------------------|-----------------------------------------------------------------| |
|
| encoding | | Encoding dictionary showing original values of encoded features.| |
|
| two-years-recidividity | Binary classification | Will the defendant be a violent recidivist? | |
|
| two-years-recidividity-no-race | Binary classification | As above, but the `race` feature is removed. | |
|
| priors-prediction | Regression | How many prior crimes has the defendant committed? | |
|
| priors-prediction-no-race | Binary classification | As above, but the `race` feature is removed. | |
|
| race | Multiclass classification | What is the `race` of the defendant? | |
|
