(eng): We propose algorithms for Tucker tensor decomposition, which can avoid computing singular value decomposition or eigenvalue decomposition of large matrices as in the work-horse higher order orthogonal iteration (HOOI) algorithm. The novel algorithms require computational cost of O(I^3R), which is cheaper than O(I^3R + IR^4 + R^6) of HOOI for multilinear rank-(R, R,R) tensors of size I × I × I.
