The following is the peer review of the project proposal by [name of team completing peer review]. The team members that participated in this review are

The aim is to effectively detect fraudulent transactions by employing ensemble learning techniques such as bagging, boosting, and stacking. The focus lies in comprehending the underlying reasons behind the varying effectiveness of these models in different scenarios. This analytical approach aids in determining the optimal method for fraud detection.

They analyzed a dataset of 550,000 credit card transactions by European cardholders in 2023. It includes 31 features, such as transaction IDs, anonymized attributes (V1-V28), transaction amounts, and a binary fraud classification. The anonymization protects privacy, while the binary classification suits supervised fraud detection methods.

The research question will be addressed through a comparative analysis of anomaly detection algorithms, focusing on machine learning models such as Random Forest, XGBoost, and Artificial Neural Networks, alongside ensemble techniques like stacking. This assessment will involve training and testing various models and ensemble techniques, comparing their performance metrics such as accuracy, precision, recall, and F1-score. Through this approach, the study aims to not only assess individual algorithm strengths but also uncover potential synergies leading to a more accurate and reliable fraud detection system.

The proposal is well-structured and detailed, providing a clear overview of the project's objectives, motivation, dataset, research questions, and analysis plan.

  1. Explicitly Define Success Metrics: Clearly define the success metrics for evaluating the performance of different machine learning models and ensemble techniques. This could include metrics such as accuracy, precision, recall, F1-score, and AUC-ROC. Having well-defined success criteria will help in objectively assessing the effectiveness of the models.
  2. Consider addressing the potential issue of imbalanced data, where fraudulent transactions may be significantly outnumbered by legitimate ones. Explore techniques such as oversampling, undersampling, or using algorithms specifically designed for imbalanced datasets to ensure that the models are not biased towards the majority class.

We are interested about how they are going to implement the staking methods, which approach would be the best method and how are they going to deepen their understanding of how these models work.
