A new research paper challenges the validity of data-free metrics used to analyze neural networks, particularly those derived from Random Matrix Theory (RMT). The study demonstrates that these RMT-based metrics can be arbitrary and unrelated to a model's performance or generalization capabilities. This is shown by functionally preserving reparametrizations of pre-trained models, where robust layers can be altered without affecting the model's behavior, leading to arbitrary metric values. The research suggests that the 'good' ranges often observed for these metrics may be heavily influenced by initial model setup. AI
