A new paper published on arXiv questions the measurement of preprocessing invariance in spectral foundation models, using a Raman foundation model as a case study. The research suggests that current methods may incorrectly attribute invariance to learned parameters when it is actually a result of the normalization process itself. The study found that the model did not significantly outperform its own normalization on six Raman evaluation datasets, indicating that the claimed invariance might not be learned. Similar findings were replicated on two other systems, suggesting a broader issue in how preprocessing invariance is assessed in spectral foundation models across various modalities. AI
IMPACT This research may lead to revised evaluation methodologies for AI models, ensuring that claimed invariances are genuinely learned capabilities rather than artifacts of preprocessing.
