TRANSACTION ANALYSIS CONSOLE

Evaluate an individual payment

Use a verified sample or enter all transaction features manually.

Transaction feature matrix

Quick demonstration Load a verified record from the held-out test data.

Time is measured in seconds from the dataset's first transaction. V1–V28 are privacy-preserving PCA features.

Batch transaction analysis

Download sample CSV
Upload transaction portfolio CSV with Time, V1–V28 and Amount. The Class column is optional.

MODEL GOVERNANCE

Built for an imbalanced reality

Evaluation choices reflect the real cost of rare-event prediction.

01
99%

High accuracy can hide failure

Predicting every payment as normal can exceed 99% accuracy while detecting zero fraud. Precision, recall, F1 and PR-AUC expose useful performance.

02
W

Rare fraud receives attention

Class weights apply larger training penalties to missed fraud examples. This can increase recall while introducing a precision trade-off.

03
M

Evidence decides the winner

Logistic regression and a compact neural network use the same split. Their precision, recall, F1 and PR-AUC determine whether deep learning truly helps.

Academic demonstration—not a production banking decision system.

Real deployments require secure data pipelines, calibration, drift monitoring, regulatory review and human oversight.
