Google Cloud Platform: BigQuery Explainable AI
Lichtendahl, Kenneth C. Jr.; Boatright, BenjaminTechnical Note DARDEN-QA-0943-EDecision AnalysisMachine-learning (ML) models have become a common tool used across a multitude of industries to help people make decisions. As these models have increased in predictive power, many have also grown in complexity. The pursuit to improve the accuracy of predictions has diminished the interpretability of many models—leaving users with little understanding of the model’s behavior or trust in its predictions. The field of eXplainable artificial intelli...Starting at €8.20
