Random Forest

Primary Classifier

Primary

Ensemble of 300 decision trees trained on 111K labelled transactions with SMOTE rebalancing. Votes across trees to produce a calibrated fraud probability score.

Tracks

  • Transaction velocity (60-min window)
  • Network topology: cycle, fan-out, scatter scores
  • Balance drain ratio & round-amount flag
  • Device novelty & previous failure count
  • Temporal patterns (hour sin/cos encoding)

Results

Accuracy96.52%
ROC-AUC0.9952
F1 (fraud)0.9579
Precision97.45%
Recall93.59%

Isolation Forest

Anomaly Detector

Secondary

Unsupervised outlier detector that isolates anomalies by recursively partitioning the feature space. No fraud labels required — flags transactions that deviate from the learned distribution.

Tracks

  • Multivariate outliers across all 16 features
  • Novel transaction patterns not seen in training
  • Structurally anomalous amount–velocity combinations
  • Unseen merchant category and device pairings
  • Distribution shift across all graph topology scores

03SCALER

Standard Scaler

Feature Normalisation

Pipeline

Fitted on the training distribution; transforms all 16 raw features to zero-mean, unit-variance before RF inference. Ensures probability calibration is stable across transaction magnitude ranges.

Tracks

  • All 16 feature dimensions before classifier input
  • Training distribution mean and variance
  • Zero-mean, unit-variance normalisation
  • Consistent scale across amount, age, velocity
  • ONNX-exported for runtime parity with training
