Nick Cammarata 发表了一篇长达 26,000 字的博客文章，主张我们对神经网络内部运作方式的理解可能存在根本性偏差。
Cammarata's extreme stress experiment showed that after compressing 480 curve-detecting neurons in a certain layer of InceptionV1 down to 10 and retraining, these neurons were still clearly interpretable rather than chaotically superposed.
Cammarata admits that his article is only a working hypothesis, does not yet cover multimodal models, and that language models lack training checkpoint data.
Cammarata proposes the theory of recursive generalization, arguing that neurons gradually expand their responses along continuous dimensions of semantic or perceptual features during training, leading to apparent polysemanticity.
Nick Cammarata's analysis points out that InceptionV1's 4e:55 neuron actually detects a V-shaped geometric form, rather than cat faces or car fronts.
In 2020, Cammarata and Chris Olah provided evidence in the paper "Zoom In" showing that the network hides car feature signals inside a group of dog neurons, reinforcing the superposition hypothesis.
