PREF-XAI: Preference-Based Personalized Rule Explanations of Black-Box Machine Learning Models

The key move here is framing explanation generation as a preference-learning problem, which means the system must first learn what a given user finds useful before it can explain anything. That is a meaningfully different architecture from post-hoc methods that generate a single explanation and assume the user will adapt to it.

The interpretability thread in our recent coverage has mostly lived at the structural level. The ORCA paper from arXiv cs.LG on April 16 tackled SVM interpretability by decomposing decision functions into explicit feature contributions, a method aimed at technical auditors who want mathematical rigor. PREF-XAI is solving a different layer of the same problem: not how to produce a formally correct explanation, but how to produce one that a specific person will actually use. The MIT Technology Review piece on public sector AI deployment (April 16) is a useful backdrop here, since constrained government environments are exactly the kind of setting where explanation audiences vary wildly, from procurement officers to data scientists.

The real test is whether PREF-XAI's preference-elicitation overhead proves acceptable in practice. If a follow-up study shows that users require more than a handful of feedback rounds before explanations stabilize, adoption in time-sensitive or low-engagement contexts will be limited regardless of explanation quality.
