Citadel Radar, your AI performance monitoring solution, is now available in beta

May 10, 2021
Citadel AI Inc., the leader in improving AI performance, has launched the beta version of Citadel Radar.
Citadel Radar provides automated monitoring for your data and model – improving real-world prediction quality and reducing maintenance time & cost. 

As society grows increasingly reliant on AI systems, concerns about AI accountability and bias are emerging in Europe and the United States, with the EU announcing proposed regulations on the use of artificial intelligence in April 2021. 

Without proper monitoring tools, AI systems become fragile black-boxes in your decision-making process, which are easy to break and difficult to fix. In order to build reliable AI systems, technology companies such as Google and Microsoft have published operational playbooks and ethical guidelines for AI.

After deployment, AI systems require constant attention to maintain real-world prediction quality while eliminating bias. However, for many companies, it's a significant challenge and cost for busy data scientists and software engineers to continuously maintain AI systems.

Citadel Radar automatically monitors enterprise AI systems, detecting, blocking, and visualizing a wide range of real-world risks (for example: data drift, invalid data, outliers), and can be applied to almost any ML model and application without requiring modifications.

Common problems with real-world AI performance

  • Performance gap between offline and real-world data
  • Sudden or gradual performance drop due to data drift
  • Bad predictions on low quality, outlier data points
  • Hard to debug or understand black-box predictions
  • Hard to A/B test new model versions
  • and many more...

Citadel Radar provides automated monitoring for your data and model

  • Automated health alerts and analytics that detect performance degradation, data drift, and data gaps.
  • Improve AI performance by validating real-world data quality with hundreds of tests for invalid, outlier and adversarial data.
  • Explain any real-world prediction, of any model, at any time from local feature importance to counterfactuals.
