ssad 0.1.2

Framework for self-supervised training of reconstruction-based autoencoder models for anomaly detection.

SSAD — Self-Supervised Anomaly Detection Library

A Python library for autoencoder-based anomaly detection with self-supervised training and dynamic per-sample confidence updates.

Key Features

• Compute per-sample anomaly scores
• Estimate confidence from score distributions
• Recalibrate confidence intervals during training
• Apply confidence-aware losses (normal / abnormal / uncertain)
• Track experiments and artifacts with MLflow

Installation

pip install ssad

For development setup:

pip install -e .[dev]
