The Woodbury formula is used when performing corrections where this quantity is fixed. A determinantal variety is a space where this quantity is bounded. n plus this quantity of AB is greater than or equal to this quantity of A plus this quantity of B, (-5[1])according to Sylvester’s inequality of this quantity. The CUR approximation is a more interpretable way to reduce this quantity compared to using the Eckart-Young theorem, which finds (15[1])approximations where this quantity is small by truncating the (*) SVD. (10[1])This quantity always equals 1 for nonzero outer products, and in general, it equals the number of nonzero singular values. (10[2])The number of columns of a matrix equals the dimension of the kernel plus this quantity, according to the this quantity—nullity theorem. For 10 points, name this quantity that equals the number of linearly independent rows or columns of a matrix. ■END■ (10[1])
