What-If Tool

NOT ON THE CURRENT EDITION
This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

机器学习世界的研究重点稍微从探索“模型能够理解什么”,转向了研究“模型是如何理解的”。由于人们担心引入偏差,或者过度泛化模型的适用性,因此开发出了What-If Tool(WIT)这样的工具。这个工具可帮助数据科学家深入研究模型的行为,并将各种功能和数据集对输出的影响进行可视化。WIT由Google引入,简化了比较模型、切片数据集、可视化构面和编辑单个数据点等任务,并可以在TensorboardJupyter notebooks中使用。尽管WIT可以帮助执行分析,但研究者仍然需要对模型背后的数学和理论有深刻的理解。WIT只是数据科学家用来深入了解模型行为的工具,对于使用不当或缺乏训练不佳的算法,初级用户不应奢望有任何工具可以消除或减轻其风险或造成的损害。
