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...

then converting it back to a jagged tensor. The forward pass is just fine, but the backwards pass breaks. It is probably because the offsets object changes throughout the forward pass, but I cannot see how to fix this.
FractalTensor is a nested list-based abstract data type (ADT), where each element is a tensor with static shape or another FractalTensor (i.e., nested). DNNs are then defined by high-order compute operators like map/reduce/scan and data access operators...
The tensor product model transformation (TPMT) is an emerging numerical framework of the Takagi-Sugeno (T-S) fuzzy (or polytopic) system modeling for a linear matrix inequality based system control design. A nested TPMT (NTPMT) is proposed in this paper, which merges the dimensions of the ...
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...
一个RaggedTensor(或flat_values,如果nested_row_splits为空)。 从row_splits 张量的嵌套列表创建 RaggedTensor。 相当于: result = flat_values for row_splits in reversed(nested_row_splits): result = from_row_splits(result, row_splits) 相关用法 Python tf.RaggedTensor.from_nested_row_lengths用...
