概述
Cynthia Rudin argues that high-stakes settings should prefer interpretable models when they perform adequately for the task, rather than assuming an explanation can make any black box trustworthy. The choice requires evidence about accuracy, fidelity, and human use.
深入探讨
An interpretable model is designed so a person can understand how its inputs produce its outputs. A black-box model may be too complex for direct human inspection or may be proprietary. Post-hoc explanation methods add a separate explanation after a prediction; the explanation can be useful, but it may only approximate the original model’s behavior. Cynthia Rudin argues that high-stakes decisions should prefer inherently interpretable models when they can achieve adequate performance, instead of treating post-hoc explanations as a complete remedy for an opaque system. The argument is strongest for structured problems where compact scoring systems, sparse linear models, rule lists, or generalized additive models can represent the task well. Rudin’s discussion includes examples from criminal justice, medicine, and other domains and cautions against the assumption that black boxes always outperform transparent alternatives. This is not a universal claim that simple models match deep learning on every task. Image, speech, and language problems may have different complexity and evidence. Model choice should follow the task, validation results, and cost of errors. Interpretability is not the same as fairness, accuracy, or usability. A readable model can encode a discriminatory target, use poor data, or be misunderstood by decision-makers. A post-hoc explanation can also mislead if it is unstable or unfaithful. Teams should compare candidates on appropriate held-out data, calibrate uncertainty, measure subgroup performance, and test whether intended users can correctly reason about the model. For high-stakes decisions, a person should be able to identify the features and rules that drove the result and challenge errors. A procurement review should request model structure, validation details, and evidence that explanations faithfully reflect computations. Ask whether a simpler model can meet the required performance and whether the use is justified at all. If a black box is retained, document why alternatives were inadequate, limit its authority, monitor failures, and provide meaningful human review and appeal.

The Future of Interpretable Models vs Black Boxes in High-Stakes Decisions
Interpretability methods and model capabilities continue to change. Reassess the tradeoff when new transparent models meet a task’s performance needs or when the black box changes. High-stakes procurement should preserve evidence for why a design was selected and ensure that affected people can obtain review rather than treating a visual explanation as accountability. Revalidate the selection when data or policy changes. Involve intended reviewers in usability testing and keep an appeal path for affected people. Save the model-selection rationale for later review.

常见问题
What is Interpretable Models vs Black Boxes in High-Stakes Decisions?
Inherently interpretable models expose how their predictions are computed in a form people can inspect, while post-hoc explanations approximate the behavior of a more complex black-box model. Cynthia Rudin argues that high-stakes settings should prefer interpretable models when they perform adequately for the task, rather than assuming an explanation can make any black box trustworthy. The choice requires evidence about accuracy, fidelity, and human use.
What distinguishes an inherently interpretable model from a black box with a post-hoc explanation?
Inherent interpretability concerns the model itself; a post-hoc method explains a more complex model after the prediction.
What does Cynthia Rudin recommend for high-stakes decisions when performance is adequate?
Rudin argues that inherently interpretable models should be preferred when they can perform adequately for the task.
Is “simple models always match black-box accuracy” a valid conclusion?
The guide limits the claim: structured tasks may admit adequate interpretable models, but not every task does.
Why can a post-hoc explanation be risky?
Post-hoc explanations can approximate or misrepresent the original model.
How should candidate models be compared?
Comparable validation on the same held-out data supports a meaningful model comparison.
