Use-case gallery

The use-case gallery is organized by problem theme. This is usually the best way to enter the documentation: choose the topic that looks like your application, then open a card with plots, captured output, and interpretation.

Start here

If you are new to the package, start with one of these three examples:

Fraud and security

Suspicious tabular records, network traffic anomalies, and robust distance ranking.

Finance and risk

Heavy-tailed covariance, portfolio stress, and market-risk style examples.

Real ML datasets

Breast cancer, digits, and wine examples with sklearn baseline comparisons.

Browse by topic

Finance
risk

Finance and risk

Portfolio covariance, stress monitoring, and heavy-tailed returns.

Fraud
security

Fraud, security, and networks

Fraud-like screening and network-flow anomaly examples.

Sensors
quality

Sensors and quality control

Sensor anomaly, predictive maintenance, and process monitoring.

Signals
embeddings

Biomedical, image, and embedding data

Feature-vector anomaly detection for signals, images, and embeddings.

Real ML
datasets

Real ML datasets

Reproducible built-in datasets with baseline metrics and plots.

ML
preprocess

Robust ML preprocessing

Use robust distances before downstream classification.
