PyTorch NestedTensors优化方案 接下来,评估在PyTorch NestedTensors下的应用。这是一个目前处于原型阶段的特性,它允许我们直接处理不同长度的张量,这些张量被称为"jagged"或"ragged"张量。这种方法避免了显式填充的需求,但需要特别注意张量操作的兼容性。 以下代码展示了如何使用NestedTensors处理变长序列: def nested...

🐛 Describe the bug Calling loss.backward() after passing a nested_tensor through nn.ReLu or nn.GELU raises a NotImplementedError. import torch import torch.nn as nn L, E = (1, 2), 3 x = torch.nested.nested_tensor([ torch.rand(L[0], E), t...
The resultant fuzzy model is in a multilevel nested tensor product (TP) structure. The vertex tensor obtained by NTPMT has fewer dimension results than the original TPMT so the number of vertices or fuzzy rules, which have been the main bottleneck for further application of the TPMT in ...
In a first part, we present a new tensor decomposition that we call Tucker train decomposition or nested Tucker decomposition (NTD). NTD can be viewed as a particular case of tensor-train decomposition recently proposed for representing and approximating high-dimensional tensors in a compact way....
而 treevalue 最为强大的地方体现在treetensor中,只需要对部分 torch.Tensor 的方法进行特别支持后,剩下的全部方法均可在现有框架上实现,并保持和原有API一样的使用方式。 这一点,意味着对于基于 treevalue 的开发者而言,不再需要大规模逐个进行封装迁移,只需要针对个别较特殊的API进行特别实现,其他的可以直接批量...

nested data parallelism and fine-grained data access patterns, opening new opportunities for whole program analysis and optimization. To exploit these opportunities, from the FractalTensor-based code the compiler extracts a nested multi-dimensional dataflow graph called...
