Researchers have developed a novel method called cross-trajectory chimera interventions to investigate the portability of learned features in neural networks. By splitting weight vectors into magnitude and direction components and recombining them between independently trained networks, they found that the direction of weights carries a transferable circuit identity, while magnitude has a more limited, distributed effect. This suggests that weight direction dictates the specific solution a network approaches, and its susceptibility to being overwritten. AI
