question about kde implementation. #17

Closed OuyangJunyuan closed 1 year ago

OuyangJunyuan commented 1 year ago

I find the following code in this repo:

return self.kde_func.log_prob(input).sum(-1).exp()

However, I think it should be performed exp before the sum operation. Is there any problem about my understanding?
