AI总结:

本文研究黑盒毒性 API 持续更新对研究可复现性的影响,通过用新版 Perspective API 重评 HELM 模型发现基础模型排名改变,并提出跨研究比较与长期毒性评估的建议。

摘要:

人们对毒性的感知会随时间演变,而且在不同地域和文化背景之间往往存在差异。同样,用于检测毒性的商用黑盒 API(例如 Perspective API)并非一成不变,而是会频繁重新训练,以解决此前未被注意到的弱点和偏见。我们评估了这些变化对可复现性的影响,这里的可复现性涉及那些比较旨在抑制毒性的模型和方法相对优劣的研究结论。我们的研究结果表明,依赖沿用下来的自动毒性评分来比较模型和技术的研究,可能已经得出了不准确的结论。使用最新版本的 API,对广受认可的“活基准”HELM 中的所有模型重新进行毒性评分后,广泛使用的基础模型出现了不同的排名。我们建议在不同研究之间进行同类比较时保持谨慎,并就如何随时间推移采用更结构化的毒性评估方法提出建议。代码和数据可在 https://github.com/for-ai/black-box-api-challenges 获取。

英文摘要:

Perception of toxicity evolves over time and often differs between geographies and cultural backgrounds. Similarly, black-box commercially available APIs for detecting toxicity, such as the Perspective API, are not static, but frequently retrained to address any unattended weaknesses and biases. We evaluate the implications of these changes on the reproducibility of findings that compare the relative merits of models and methods that aim to curb toxicity. Our findings suggest that research that relied on inherited automatic toxicity scores to compare models and techniques may have resulted in inaccurate findings. Rescoring all models from HELM, a widely respected living benchmark, for toxicity with the recent version of the API led to a different ranking of widely used foundation models. We suggest caution in applying apples-to-apples comparisons between studies and lay recommendations for a more structured approach to evaluating toxicity over time.
