Researchers have introduced a formal definition for Fundamental Representational Units (FRUs) within neural networks, proposing criteria for fidelity and stability. Their work demonstrates that Threshold-activated sparse autoencoders (TSAEs) can effectively identify these FRUs under specific conditions, as validated by extensive experiments. The study further indicates that more stable FRUs correlate with higher monosemanticity and can be combined across network layers to reflect human conceptual structures, offering a framework for understanding the link between neural network representations and human cognition.
