Robust Anomaly Detection And Recognition (RADAR)

📌 Description

Robust Anomaly Detection And Recognition (RADAR) is an anomaly detection platform designed to unify and integrate diverse approaches and libraries from the literature, along with innovative model variants. The goal is to provide a flexible and extensible framework that ranges from classical methods to advanced techniques based on Transformer architectures, also including support for Federated Learning in distributed scenarios. For more details, refer to the official documentation here.

Specifically, it includes:

• Classical methods for static data: integration with PyOD and Scikit-learn.
• Time series and deep learning models: integration with libraries such as TSFE-DL.
• Representative Transformer models: Informer, Autoformer, and Vanilla Transformer (implemented within the time_series/ folder).
• Federated anomaly detection: integration with flex-anomalies, developed as part of the Flexible platform.

🧪 Examples and Utilities

The library provides a set of practical examples and utilities to make experimentation easier:

• Test Notebooks: The notebooks_test/ folder contains a notebook for each library integration, showing how to use the algorithms with different types of data.
• Preprocessing Scripts: Each time_series/ and static_data/ folder includes a preprocessing/ folder with techniques tailored to the specific data type:
  • preprocessing/preprocessing_static.py for static data
  • preprocessing/preprocessing_ts.py for time series data
• Dataset Loaders: The same folders provide a datasets_uci.py file with functions to load datasets from the UCI repository, making it easy to test and experiment with the library:
  • static_datasets_uci.py for static data
  • time_series_datasets_uci.py for time series data
• Metrics: metrics_module.py provides evaluation metrics for anomaly detection.
• Visualization: visualization_module.py includes functions to plot results and anomalies.
• Post-processing: pos_process_module.py computes anomaly labels from predictions.

Note that federated_data/ does not contain its own preprocessing or dataset loader scripts, since it can work with either static or time series data. The example notebooks cover usage for both types.

This setup allows users to explore the library’s functionality, apply the appropriate preprocessing, and test algorithms on real datasets efficiently.
