Want to understand why a computed tomography classifier made a prediction? The code just went online for generating counterfactual explanations for 2D/3D CT classifiers! Here is an explanation for Plural Effusion: #radiology #radiologyai @StanfordAIMI https://t.co/1Kh3tCQyMP

Proof that consciousness doesn't exist: - An atom isn't conscious. - Adding an atom to something that's not conscious doesn't make it conscious. - Therefore nothing is conscious.

Vision-language conversational models for healthcare may fit a use case with physicians better than task-specific tools. How to validate them remains a challenge but the conversational interface may be the key to get adoption by physicians.

This work also discusses how to fix biased classifiers. This colab notebook will get you started with Latent Shift Counterfactuals

Counterfactuals are needed for this as overlapping heatmaps don't distinguish features well. Shown here with pointy and big noses that have overlapping heatmaps but distinct counterfactuals.

This process can be used to compute aggregate statistics over a dataset of the biases between the features used. This can identify trends to explore and you can then drill down and study specific predictions.

Counterfactual Alignment uses the alignment between classifiers when presented with counterfactual inputs (generated using the Latent Shift method) to identify features that are shared between the classifiers.

Curious why your neural network is making a prediction? Maybe it is using spurious correlations! Counterfactuals are a solution but how to use them at scale? We explore this challenge in our latest work on Counterfactual Alignment! https://t.co/tYH9Ttxj8B https://t.co/vMI97LCnvX
