最简单的,因为torch没有js散度的内置实现 那肯定要问出这样一个问题,js散度不过就是对称的kl散度,...
F.kl_div(log(x),y,others) x需要先取log 再进入,主要是pytorch自己的定义 cpp:auto output_pos = target * (at::log(target) - input); 可以看下面的连接 https://pytorch.org/docs/stable/generated/torch.nn.KLDivLoss.html codehttps://github.com/pytorch/pytorch/blob/7cc029cb75c292e93d168e11...

I assume as this is missing from both of these libraries that there is some good reason for this and that the user would be expected to implement it themselves with tfp.distributions.RegisterKL in TensorFlow Probability and torch.distributions.kl.register_kl in PyTorch. Is this the correct assu...
