Style or Content? Evaluating Style Classifiers with Controlled Content Overlap

arXiv:2606.07103v1 Announce Type: new Abstract: Style classifiers can use content cues that correlate with style labels in naturally collected data, yet we lack a systematic way to measure this reliance. We study this problem with a controlled content overlap setup built on parallel Bible translations. Specifically, we define the overlap parameter $\alpha$ as the normalized residual of mutual information between content identity and style label, so that it measures how much content is shared across style classes: from no shared content ($\alpha=0$) to fully shared content ($\alpha=1$). Cross-o

Why this matters
Why now

The proliferation of AI models makes it critical to understand their underlying mechanisms and potential biases, particularly as they integrate more deeply into complex systems.

Why it’s important

This research provides a systematic method to evaluate style classifiers, offering insights into how AI models differentiate between stylistic and content features, which is crucial for ethical and effective AI development.

What changes

We now have a quantifiable method, the overlap parameter $\alpha$, to assess the degree to which content cues influence style classifications in AI models, moving beyond qualitative assessment.
