A new research paper from arXiv questions the validity of common methods used to probe language models for conceptual understanding. The study highlights that concept probes, while accurate in predicting concepts, can be heavily influenced by correlated nuisance attributes rather than the target concept itself. This nuisance sensitivity can lead to misleading interpretations of a model's internal representations, even when decodability scores appear high. The researchers propose using nuisance-aware development diagnostics as a more reliable validation method, which requires nuisance labels but not counterfactual data. AI
