1. RepresentationSparse vector: (4, [0,2,3], [1.0,3.0,4.0])Corresponding original vector: (1.0,0.0,3.0,4.0)Sparse vectors are divided into three corresponding elements: (size, indices, values)Note: where size is the length of the original vector, indexes is the index subscript of the non-zero position in the original vector, values is the corresponding value of the non-zero subscript in the original vector, and […]
