Towards Rigorous Explainability by Feature Attribution
Summary
The field of explainable artificial intelligence (XAI) has predominantly relied on non-symbolic methods for explaining complex machine learning models over the past decade. However, these methods, exemplified by the widespread use of Shapley values and tools like SHAP, often lack rigor and can potentially mislead human decision-makers, particularly in high-stakes applications. This overview highlights current research efforts focused on developing and adopting rigorous symbolic methods for XAI. The primary goal of these symbolic approaches is to provide a more robust and trustworthy alternative for assigning relative feature importance, addressing the inherent limitations and potential inaccuracies of their non-symbolic counterparts.
Key takeaway
For research scientists developing or deploying ML models in high-stakes environments, you should critically evaluate the rigor of your XAI methods. Consider exploring symbolic XAI approaches to ensure more trustworthy and less misleading explanations, especially when assigning feature importance, to mitigate risks associated with non-rigorous techniques like Shapley values.
Key insights
Symbolic XAI methods offer rigorous alternatives to non-symbolic approaches for reliable feature importance attribution.
