Noblis has been granted US Patent No. 12,554,993 for Beagle, a genetic programming technology that evolves computer code using principles similar to biological evolution to solve complex problems. The system mimics natural selection, evolving the most effective code solutions at unprecedented scale. By leveraging GPU architecture, Beagle accelerates the evolutionary process by orders of magnitude compared to previous genetic programming approaches. The technology produces explainable, human-readable solutions rather than black-box answers, making it suitable for applications requiring precision and accountability in scientific research, national security and financial modelling. Beagle has successfully derived formulas for quadratic equations, created polynomial approximations for trigonometric functions, and beat traditional neural networks by up to 61% in predicting California housing prices. It significantly outperforms current systems on the Feynman100 benchmark for symbolic regression.
Noblis appoints Dr. William Streilein as chief technology officer.
On July 22, Noblis, Inc. announced that its corporate venture arm, Noblis Ventures, has made a strategic investment in Prediction Guard, a cloud software company specializing in secure, self-hosted artificial intelligence (AI) systems for high-security environments.
