Webtensor Rvanish. Tensor V is fixed (does not change between iterations). Ranges of all indices are proportional to system size N, hence each tensor has N4 space complexity, and the operation has N6 operation complexity. The tensor contraction in Equation (1) can be viewed as a multiplication of matrix T (with fused indices ij and cd
Web1 Sep 2024 · A key tool underpinning multi-linear manipulation of tensors and tensor networks is the standard Tensor Contraction Product (TCP). However, depending on the dimensionality of the underlying tensors, the TCP also comes at the price of high computational complexity in tensor manipulation.
