we can capture the differnece between two encoding cluster results. First one is from AE and shows irregular shape. But what is difference between two square lattice inscribed within the red disk? They seem same.

    The second square lattice represents the sampled points from the latent space. (Yes, they are the same)
    Suppose we apply the same sampling procedure for both the AE and the VAE, as shown on the right. In that case, the VAE will produce more plausible reconstructions than the AE. This is because most of the sampled points in the VAE lie within the latent distribution, which is smooth and well-regularized. In contrast, the AE’s latent space tends to be irregular, causing sampled points to fall outside the meaningful regions of the latent space, resulting in less plausible outputs.
