# Model description |
|
|
|
|
|
This is a logistic regression model trained on customers' credit card risk data in a bank using sklearn library. |
|
|
The model predicts whether a customer is worth issuing a credit card or not. The full dataset can be viewed at the following link: https://huggingface.co/datasets/saifhmb/CreditCardRisk |
|
|
|
|
|
|
|
|
|
|
|
## Training Procedure |
|
|
|
|
|
The data preprocessing steps applied include the following: |
|
|
- Dropping high cardinality features, specifically ID |
|
|
- Transforming and Encoding categorical features namely: GENDER, MARITAL, HOWPAID, MORTGAGE and the target variable, RISK |
|
|
- Splitting the dataset into training/test set using 85/15 split ratio |
|
|
- Applying feature scaling on all features |
|
|

## Evaluation Results |
|
|
- The target variable, RISK is multiclass. In sklearn, precision and recall functions have a parameter called, |
|
|
average. This parameter is required for a multiclass/multilabel target. average = 'micro' was used to calculate |
|
|
the precision and recall metrics globally by counting the total true positives, false negatives and false positives |
|
|
|
|
|
| Metric | Value | |
|
|
|-----------|----------| |
|
|
| accuracy | 0.699187 | |
|
|
| precision | 0.699187 | |
|
|
| recall | 0.699187 | |
