Key Contributions / Features
- Eckart-Young theorem (Eckart-Young 1936): with Carl Eckart, established that the truncated singular value decomposition gives the optimal least-squares low-rank approximation of a matrix (Low-Rank Approximation); also contributed to early work on matrix decompositions in factor analysis.
