UnverifiedEarly interpretability research found that a certain neuron activated strongly to both cat faces and car fronts, and this phenomenon was called polysemanticity.76% similarUnverifiedNick 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.69% similarUnverifiedAfter re-analysis, Camerota concluded that neuron 4E.55 is actually a V-shape detector, and that its "cat-car hybrid" appearance is an artifact artificially manufactured by the visualization optimization algorithm exploiting biases in the training data (many animal-face photos).67% similarUnverifiedOlshausen和Field在1996年的工作表明，V1神经元的感受野与ICA在自然图像上学到的基函数高度吻合67% similarUnverified神经元激活可视化是AI可解释性研究的核心议题之一65% similar
