z_est_bn = (z_est[l] - m) / v

[daniadag]

why we need to put this line in decoder in line 179??? after you apply batch normalization

it seems like you apply mean and v for output layer before and after g_gauss
u = batch_normalization(u)
z_est[l] = g_gauss(z_c, u, layer_sizes[l])
z_est_bn = (z_est[l] - m) / v
