-# NTCU Machine Learning Assignment Repository
-**NTCU-Machine-Learning** repository for the Machine Learning course at NTCU. 
-This repository is used for submitting assignments related to machine learning projects, with a focus on **Credit Card Fraud Detection**.
-
-## Project Overview
-This assignment focuses on building a machine learning model for **credit card fraud detection**. 
-You will use a dataset to train and evaluate models, applying techniques such as data preprocessing, feature scaling, and classification algorithms (e.g., Random Forest) or clustering (e.g., KMeans).
-
-**Objectives:**
-- Load and preprocess the dataset.
-- Train a machine learning model to detect fraudulent transactions.
-- Evaluate the model using metrics like accuracy, precision, recall, F1-score, ROC AUC, and confusion matrix.
-
-## Setup Instructions
-To set up your environment and work on the assignment, follow these steps:
-
-### 1. Fork the Repository
-- Fork the `NTCU-Machine-Learning` repository to your GitHub account.
-- Clone your forked repository to your local machine:
-  ```bash
-  git clone <your-forked-repo-url>
-  ```
-
-### 2. Install Git
-Ensure Git is installed on your system:
-- **Windows/Mac**: Download and install Git from [git-scm.com](https://git-scm.com).
-- **Ubuntu/Linux**:
-  ```bash
-  sudo apt update
-  sudo apt install git
-  ```
-
-## Submission Guidelines
-1. **Fork and Clone**: Fork this repository and clone it to your local machine.
-2. **Create a Branch**: Create a branch for your assignment (e.g., `assignment-<your-student-id>`).
-3. **Implement Your Code**: Modify the provided code template (see [Code Structure](#code-structure)) to complete the assignment.
-4. **Commit and Push**:
-   ```bash
-   git add .
-   git commit -m "Submit assignment for <your-student-id>"
-   git push origin <your-branch-name>
-   ```
-5. **Create a Pull Request**: Submit a pull request from your forked repository to the main repository for review.
-6. **File Naming**: Name your main script as `<ex_number>.py`.
-7. **Create a New Folder**: Remeber put your each file into `<your-student-id>_<ex_number>`.
-
-**Important**:
-- Do not modify the `TEST_SIZE` (set to `0.3`) or `RANDOM_SEED` (set to `42`) in the code.
-- Ensure your code is well-documented with comments explaining your approach.
-- Submit your pull request before the deadline.
-
-## Dataset
-The dataset for this assignment is available via **KaggleHub**. Use the following code to load it:
-```python
-import kagglehub
-path = kagglehub.dataset_download("mlg-ulb/creditcardfraud")
-data = pd.read_csv(f"{path}/creditcard.csv")
-```
-
-- The dataset contains credit card transaction data with features like transaction amount, time, and anonymized features (`V1` to `V28`).
-- The target variable is `Class` (0 for non-fraudulent, 1 for fraudulent).
-
-### Tasks
-1. Preprocess the data (e.g., handle missing values, scale features using `StandardScaler`).
-2. Split the dataset into training (70%) and testing (30%) sets.
-3. Train a classification model (e.g., `RandomForestClassifier`) or a clustering model (e.g., `KMeans`).
-4. Evaluate the model using the following metrics:
-   - Accuracy
-   - Precision
-   - Recall
-   - F1-score
-   - ROC AUC score
-   - Confusion Matrix
-   - (For clustering) Silhouette Score
-
-## Evaluation Metrics
-Your model will be evaluated based on:
-- **Correctness**: Does the code run without errors and produce the expected outputs?
-- **Performance**: How well does your model perform on the test set (based on the metrics above)?
-- **Code Quality**: Is the code well-organized, commented, and easy to understand?
-- **Documentation**: Include a brief explanation of your approach in the pull request description.
