这篇文章主要是把全连接层的权重进行tensor-traindecomposition,且听我慢慢道来。 首先看最基础的全连接层: 那么,下一步,我们就是对W进行tensor-traindecomposition(忘记具体形式的可看我上篇文章)转换成张量形式,同样的,为了匹配W,我们把y,x,b也都
TensorLy中提供了两种tensor train分解方式:基于SVD的分解(tensorly.decomposition.mps_decomposition) 和 基于交叉逼近的方法(tensorly.contrib.mps_decomposition_cross)。使用上文中的tensor,演示尺寸(12,12) tensor的rank [1,2,1]分解过程,第一个核的尺寸是(1,12,2)和第二个核的尺寸是(2,12,1): >>> from...

There are about a dozen other libraries implementing Tensor Train decomposition. The main difference betweent3fand other libraries is thatt3fhas extensive support for Riemannian optimization and that it uses TensorFlow as backend and thus supports GPUs, automatic differentiation, and batch processing. For...
