KubAnomaly Reconstructed Dataset with Low Anomaly Ratio

This dataset is a reconstructed version of the KubAnomaly dataset with a realistic low anomaly ratio (2.98%). The original KubAnomaly dataset contains 65.94% anomalous samples, which diverges from real container runtime environments. We apply balanced stratified down-sampling to reduce the anomaly ratio to approximately 3%, yielding 12,005 normal samples and 369 anomalous samples (123 per attack type). The repository includes the reconstructed dataset files and the preprocessing script for full reproducibility.
