WebMar 7, 2024 · In their case, the KL loss was undesirably reduced to zero, although it was expected to have a small value. To overcome this, they proposed to use "KL cost annealing", which slowly increased the weight factor of the KL divergence term (blue curve) from 0 to 1. This work-around solution is also applied in Ladder VAE. Paper:
