UnverifiedSpectral clustering maps high-dimensional data to a low-dimensional spectral space by computing the eigenvectors of the graph Laplacian matrix, and then completes clustering with k-means.66% similarUnverifiedEmbedding vectors are essentially high-dimensional numerical vectors output by intermediate layers of a neural network, typically having hundreds to thousands of dimensions, and represent the coordinates of raw input data in a learned semantic space.63% similarUnverifiedIn BERT, the word embedding matrix has dimensions V×d, where V is the vocabulary size and d is the hidden dimension 768, mapping discrete token IDs to dense real-valued vectors.62% similarVerifiedDepth estimation, which recovers three-dimensional spatial information from two-dimensional images, is an ill-posed problem because there are infinitely many possible solutions for the mapping from 2D to 3D62% similarUnverifiedpoly核将原始d维输入隐式映射到O(n^d)维特征空间，维度随degree指数级增长，计算代价急剧膨胀61% similar
