4 key tests for your AI explainability toolkit Enterprise-grade explainability solutions provide fundamental transparency into how machine learning models make decisions, as well as broader assessments of model quality and fairness. Is yours up to the job? CarlosCastilla / Getty Images Until recently, explainability was largely seen as an important but narrowly scoped requirement towards the end of the AI model development process. Now, explainability is being regarded as a multi-layered requirement that provides value throughout the machine learning lifecycle. Furthermore, in addition to providing fundamental transparency into how machine learning models make decisions, explainability toolkits now also execute broader assessments of machine learning model quality, such as those around robustness, fairness, conceptual soundness, and stability.
