Witryna4：不能这样子，于是作者设计了一个新的loss叫center loss。. 我们给每个label的数据定义一个center，大家要向center靠近，离得远的要受惩罚，于是center loss就出现了：. CenterLoss=\frac {1} {2N}\sum_ {i=1}^N x_i-c ^2_2. 5：众人纷纷表示这个思路很好，但是这个c怎么定义呢 ... Witryna21 lis 2024 · I’ve read that when data is binary, the reconstruction loss is modeled by a multivariate factorized Bernoulli distribution using torch.nn.functional.binary_cross_entropy, so the ELBO loss can be implemented like this: def loss_function(recon_x, x, mu, logvar): BCE = …

Witryna24 maj 2024 · The MSE loss is the mean of the squares of the errors. You're taking the square-root after computing the MSE, so there is no way to compare your loss function's output to that of the PyTorch nn.MSELoss() function — they're computing different values..
