However, a single solution may not be suitable in practical scenarios, as the objective functions and constraints are only approximations of original real-world situations.

To mitigate this problem, an adjustable hyperparameter $\beta$ and a strategy for annealing this parameter, called KL annealing, are proposed.

In addition, these solvers employ a continuous relaxation strategy; thus, post-learning rounding from the continuous space back to the original discrete space is required, undermining the robustness of the results.

This paper presents a closed-form expression to assess the relationship between the beta in VAE, the dataset size, the posterior collapse, and the rate-distortion curve by analyzing a minimal VAE in a high-dimensional limit.

However, SLMC methods are difficult to directly apply to multimodal distributions for which training data are difficult to obtain.
