This research introduces a powerful new technique called Token Discarding to diagnose "spurious correlations" in Vision Transformer (ViT) models. The core idea is to systematically remove parts (tokens) of an image to see which ones are most critical for the AI's prediction. This allows for the calculation of a Token Spuriosity Index (TSI), a novel metric that quantifies how much a model relies on irrelevant background information versus the actual object of interest.
Models that learn spurious correlations are a significant business risk. They may perform well in testing but fail unpredictably in production when irrelevant cues (like backgrounds, lighting, or watermarks) change. This can lead to flawed quality control in manufacturing, incorrect diagnoses in medical imaging, or unreliable object detection in autonomous systems. These failures erode trust, incur significant financial costs, and can have severe safety implications.
The paper highlights that the model's training methodology is a key factor. Using advanced self-supervised learning techniques like DINO was shown to produce models that are inherently more robust and less reliant on spurious cues compared to traditional supervised methods. Proactively diagnosing datasets and models with the TSI methodology allows for targeted data cleaning, model retraining, and the selection of more reliable architectures before deployment, mitigating risks early in the development lifecycle.
The Spurious Correlation Problem
AI vision models can appear accurate while "cheating" by focusing on irrelevant shortcuts, like a specific background texture or a watermark, instead of the actual object. This leads to models that are fundamentally unreliable and prone to failure in real-world scenarios where these spurious cues are absent.
TSI > 1.0 Indicates a model is relying more on background noise than the actual object.The Token Discarding Diagnostic Process
A principled, step-by-step method to precisely identify which image regions a model uses for its predictions, moving beyond vague heatmaps to a quantifiable score of trustworthiness.

Case Study: Medical Imaging Diagnostics
In a high-stakes breast cancer detection task using MRI images, the TSI methodology was deployed to validate fine-tuned Vision Transformer models. The results were critical for ensuring clinical safety:
Models with High TSI scores were correctly identified as unreliable. Analysis of their influence maps revealed they were focusing on non-relevant chest fat tissue instead of the actual breast mass—a potentially catastrophic failure mode.
Conversely, models with Low TSI scores were confirmed to be focusing on the correct, clinically significant regions within the breast. This diagnostic capability is crucial for vetting and deploying safe, effective, and trustworthy medical AI systems.
