About Maria Escudero
In 2021, Maria Escudero led the development of the 'LUMEN' framework, a lightweight, model-agnostic tool that translates SHAP and LIME outputs into plain-language audit reports for non-technical regulators in EU AI Act pilot jurisdictions. Unlike most explainability work focused on accuracy-preserving approximations, her team deliberately traded marginal fidelity for interpretive transparency, embedding linguistic constraints that force explanations to avoid causal overreach. She’s since testified before Spain’s National Commission on AI Ethics about how fairness metrics fail when applied to multilingual NLP pipelines trained on scraped social media data, not because of bias in labels, but because tokenization collapses dialectal nuance into false majority-class assumptions. Her lab maintains an open repository of 'explanation failure modes': real-world cases where interpretable models mislead clinicians, loan officers, or parole boards precisely because their simplicity masked distributional shifts no static metric could flag.
