A new research paper explores epistemic uncertainty in overparametrized neural networks, challenging the traditional view that this uncertainty diminishes with more data. The study highlights that non-identifiable model parameters, common in such networks due to symmetries, can lead to persistent uncertainty even when the underlying function is fully understood. The research analyzes discrete and continuous sources of this residual uncertainty, focusing on one-hidden-layer ReLU networks and validating theoretical findings with empirical studies. AI
