arXiv:2606.00635v1 Announce Type: new Abstract: Modern VAEs are rarely trained with the pointwise likelihood implied by the standard $\beta$-VAE objective. In practice, pointwise reconstruction is often combined with perceptual and adversarial losses, despite a lack of understanding of how this changes the latent dynamics of the model. We show that the choice of reconstruction loss reshapes the rate-distortion problem itself, altering both the information content and the geometry of the learned latent space in ways that may be invisible from reconstructions alone. First, we prove and verify em
This research is emerging now as VAEs become more sophisticated and widely applied, necessitating a deeper understanding of their underlying mechanics beyond simple reconstruction metrics.
Understanding how different loss functions shape VAE latents is critical for developing more robust, interpretable, and effective generative AI models, impacting accuracy and control.
The explicit proof and verification that reconstruction loss fundamentally reshapes the rate-distortion problem changes how researchers and practitioners should approach VAE design and evaluation.
