## Model Description |
|
### Keras Implementation of Imbalanced classification: credit card fraud detection |
|
This repo contains the trained model of [Imbalanced classification: credit card fraud detection](https://keras.io/examples/structured_data/imbalanced_classification/). |
|
The full credit goes to: [fchollet](https://twitter.com/fchollet) |
|
|
|
## Intended uses & limitations |
|
- The trained model is used to detect of a specific transaction is fraudulent or not. |
|
|
|
## Training dataset |
|
- [Credit Card Fraud Detection](https://www.kaggle.com/datasets/mlg-ulb/creditcardfraud) |
|
- Due to the high imbalance of the target feature (417 frauds or 0.18% of total 284,807 samples), training weight was applied to reduce the False Negatives to the lowest level as possible. |
|
|
|
## Training procedure |
|
### Training hyperparameter |
|
The following hyperparameters were used during training: |
|
- optimizer: 'Adam' |
|
- learning_rate: 0.01 |
|
- loss: 'binary_crossentropy' |
|
- epochs: 30 |
|
- batch_size: 2048 |
|
- beta_1: 0.9 |
|
- beta_2: 0.999 |
|
- epsilon: 1e-07 |
|
- training_precision: float32 |
