Why 'loss.backward()' is carried out before the k-means function?

2

In the ‘train_one_epoch‘ function，I notice that when 'loss.backward()' is carried out for the first time，the Ci is not clustered by k-means method. Clustering does not work until the second data...

A question about computing Ci by k-mean

Hi, chengxuz, I have a question. In LA part, the loss backpropogates before k-mean updation. Does this mean that the first data batch did not define Ci as mentioned in...

Hello, I'm curious about the function __get_relative_prob in Class: LocalAggregationLossModule. Specifically, why you set 'keepdim = True' in function torch.sum conducted on back_nei_probs, while, 'keepdim = False' (default setting) in...

The function in Class: LocalAggregationLossModule

I cannot understand the formulation in function "def _softmax". What is the value of 2876934.2 ?

how much time you spend on training a LA model?

It has taken me several hours while one epoch of training has not finished yet.
