Researchers have experimentally validated the long-held intuition that representational entanglement in neural networks hinders unlearning. Using a novel application of Selective Gradient Masking, they trained six language models with varying degrees of disentanglement between knowledge domains. The study found that more disentangled models consistently required significantly less retain cost to forget specific information, providing direct evidence that entanglement contributes to collateral damage during the unlearning process.
