Time per epoch Convergence speed几种GCN 类型:GCN:Full-batch gradient descent 需要计算整个所有节点的梯度,也需要存储所有 Embedding ,所以导致 O(NFL)O(NFL) 内存需求; 在每个 epoch 只更新一次参数,所以 SGD 的收敛速度缓慢; memory: bad time per epoch: good convergence: bad Mini-batch SGD 每次更新...

Even after this error, the training begins and even finishes the first epoch before arriving at the error that kills the whole process: RuntimeError: NCCL communicator was aborted on rank 0. Original reason for failure was: NCCL error: remote process exited or there was a network error, NCCL...
The training error,trainError, and validation error,chkError, arrays each contain one error value per training epoch. Plot the training error and the validation error. x = [1:30]; plot(x,trainError,'.b',x,chkError,'*r') The minimum validation error occurs at epoch 17. The increase in...
On the left, the learning rate is too low: the algorithm will eventually reach the solution, but it will take a long time. In the middle, the learning rate looks pretty good: in just a few iterations, it has already converged to the solution. On the right, the learning rate is too ...

full pass over the training dataset is called anepoch. Model trainings commonly consist of dozens to hundreds of epochs. Mini-batch SGD has several benefits: First, its iterative design makes training time theoretically linear of dataset size. Second, in a given mini-batch each record is ...
