A new research paper proposes a method to improve the accuracy of feature importance estimation in machine learning models, particularly for complex models used in critical applications like biomedical research. The study, published on arXiv, suggests that ensembling at the model level, rather than aggregating individual model explanations, yields more reliable variable importance estimates. This approach is validated through theoretical analysis and experiments on benchmarks and a large-scale proteomic study from the UK Biobank. AI
