Robust tensor factorization
Weband tensor based method in dealing with the high-order ten-sor data. The upper row is the matrix based factorization method, which needs to preliminarily unfold or vectorize the tensor; the lower row is the tensor based method which directly factorize the tensor without destroying the spatial structures. Given a high-order tensor data, an ... WebJun 27, 2024 · Finding high-quality mappings of Deep Neural Network (DNN) models onto tensor accelerators is critical for efficiency. State-of-the-art mapping exploration tools use remainderless (i.e., perfect) factorization to allocate hardware resources, through tiling the tensors, based on factors of tensor dimensions. This limits the size of the search space, …
