The goal is to build a predictive model that can identify fraudulent transactions with high accuracy, ensuring minimal false positives and negatives.\n\n---\n\n## 💡 Key Features\n- **Exploratory Data Analysis (EDA):** Understand trends, correlations, and distributions in the dataset.\n- **Data Preprocessing:** Handle class imbalance using techniques like SMOTE, and scale features for optimal performance.\n- **Machine Learning Models:** Implement various algorithms including Logistic Regression, Random Forest, and Gradient Boosting.\n- **Evaluation Metrics:** Use precision, recall and F1-score to assess model performance.\n- **Visualizations:** Include interactive visualizations for model insights and fraud patterns.\n\n---\n\n## 📂 Dataset\nThe dataset used for this project is the [Kaggle Credit Card Fraud Detection Dataset](https://www.kaggle.com/datasets/mlg-ulb/creditcardfraud). It contains:\n- **284,807 transactions** over two days.\n- **31 features** including time, amount, and anonymized PCA components.\n- An extremely imbalanced target variable where only 0.172% of transactions are fraudulent.\n\n---\n\n## 🛠️ Tech Stack\n- **Programming Languages:** Python\n- **Libraries:** Pandas, NumPy, Scikit-learn, Matplotlib, Seaborn\n- **Machine Learning Techniques:** Logistic Regression, Random Forest, Gradient Boosting\n- **Data Balancing:** SMOTE (Synthetic Minority Oversampling Technique)\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvishnu-vamshii%2Ffraud-detection-using-machine-learning","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvishnu-vamshii%2Ffraud-detection-using-machine-learning","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvishnu-vamshii%2Ffraud-detection-using-machine-learning/lists"}
