However, there is an approach that makes it possible to ensure safety requirements are met while benefiting from advances in Artificial Intelligence.<\/p>\n<p>The principle: <strong>combine an ML model with an independent safety controller<\/strong>. ML proposes a solution (for example, detecting that a railway track is free based on images), and the controller verifies its compliance with safety rules (geometry of the path, gauge, parallelism, curvature, etc.).<\/p>\n<p>Safety thus relies solely on the controller, avoiding the need to justify the internal functioning of the Machine Learning model. A proof of concept based on a <strong>U-NET<\/strong> model demonstrates the relevance and reliability of this approach.<\/p>\n<p>This combination paves the way for the use of Artificial Intelligence in critical railway functions, while complying with the highest safety standards.<\/p>\n<p>Mr Fr\u00e9d\u00e9ric HENON (UIC) France presented this work at the conference: \u201812th UIC WORLD CONGRESS ON HIGH-SPEED RAIL\u2019 from 8-11 July 2025 &#8211; Beijing, China.<\/p>\n<p>This study was conducted by CLEARSY under the direction of the Operations and Safety Department of the International Union of Railways UIC.<\/p>\n<p>Presentation here : <a href=\"https:\/\/www.clearsy.com\/wp-content\/uploads\/2026\/01\/12WCHSR_NMSD_FH_final_20.pdf\">12WCHSR_NMSD_FH_final_20<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Software safety analyses require knowledge of their algorithms, while Machine Learning (ML) models remain software \u2018black boxes\u2019.
