Abstract

Black box machine learning models are currently being used for high stakes decision-making throughout society, causing problems throughout healthcare, criminal justice, and in other domains. People have hoped that creating methods for explaining these black box models will alleviate some of these problems, but trying to explain black box models, rather than creating models that are interpretable in the first place, is likely to perpetuate bad practices and can potentially cause catastrophic harm to society. There is a way forward - it is to design models that are inherently interpretable. This manuscript clarifies the chasm between explaining black boxes and using inherently interpretable models, outlines several key reasons why explainable black boxes should be avoided in high-stakes decisions, identifies challenges to interpretable machine learning, and provides several example applications where interpretable models could potentially replace black box models in criminal justice, healthcare, and computer vision.

Saliency does not explain anything except where the network is looking. We have no idea why this image is labeled as either a dog or a musical instrument when considering only saliency. The explanations look essentially the same for both classes. Figure credit: Chaofan Chen and [28].

Figure 3:
This is a machine learning model from the Certifiably Optimal Rule Lists (CORELS) algorithm [32]. This model is the minimizer of a special case of Equation 1 discussed later in the challenges section. CORELS’ code is open source and publicly available at http://corels.eecs.harvard.edu/, along with the data from Florida needed to produce this model.

Figure 5:
Image from the authors of [49], indicating that parts of the test image on the left are similar to prototypical parts of training examples. The test image to be classified is on the left, the most similar prototypes are in the middle column, and the heatmaps that show which part of the test image is similar to the prototype are on the right. We included copies of the test image on the right so that it is easier to see what part of the bird the heatmaps are referring to. The similarities of the prototypes to the test image are what determine the predicted class label of the image. Here, the image is predicted to be a clay-colored sparrow. The top prototype seems to be comparing the bird’s head to a prototypical head of a clay-colored sparrow, the second prototype considers the throat of the bird, the third looks at feathers, and the last seems to consider the abdomen and leg. Test image from [50]. Prototypes from [51, 52, 53, 54]. Image constructed by Alina Barnett.
