VerifiedPCA dimensionality reduction finds the projection axes of maximum data variance by performing eigendecomposition on the data covariance matrix, thereby compressing dimensions while retaining the most information.78% similarUnverifiedPCA reduces the dimensionality of hidden activations from multiple samples of the same prompt; the first principal component captures the direction of greatest variance among the sampled results, corresponding to the style dimension along which the model varies most dramatically.76% similarUnverifiedPCA的主成分方向是在当前图像的token分布上单独拟合的，不同图像的主成分指向不同方向，因此颜色不携带跨图像的语义信息59% similarUnverifiedA spectral basis is a set of orthogonal basis vectors obtained through eigendecomposition, where the magnitude of the eigenvalues reflects the information content or importance of the corresponding direction.58% similarUnverifiedFrom PCA dimensionality reduction to the attention mechanism in Transformers, matrix operations and vector space transformations are fundamental.55% similar
