Generative Models with ELBOs Converging to Entropy Sums Open
The evidence lower bound (ELBO) is one of the most central objectives for probabilistic unsupervised learning. For the ELBOs of several generative models and model classes, we here prove convergence to entropy sums. As one result, we provi…

AnomalyDINO: Boosting Patch-based Few-shot Anomaly Detection with DINOv2 Open
Recent advances in multimodal foundation models have set new standards in few-shot anomaly detection. This paper explores whether high-quality visual features alone are sufficient to rival existing state-of-the-art vision-language models. …

Learning Sparse Codes with Entropy-Based ELBOs Open
Standard probabilistic sparse coding assumes a Laplace prior, a linear mapping from latents to observables, and Gaussian observable distributions. We here derive a solely entropy-based learning objective for the parameters of standard spar…

Towards the Detection of Diffusion Model Deepfakes Open
In the course of the past few years, diffusion models (DMs) have reached an unprecedented level of visual quality. However, relatively little attention has been paid to the detection of DM-generated images, which is critical to prevent adv…

The ELBO of Variational Autoencoders Converges to a Sum of Three Entropies Open
The central objective function of a variational autoencoder (VAE) is its variational lower bound (the ELBO). Here we show that for standard (i.e., Gaussian) VAEs the ELBO converges to a value given by the sum of three entropies: the (negat…
