DE-VAE: Revealing Uncertainty in Parametric and Inverse Projections with Variational Autoencoders using Differential Entropy

arXiv — cs.LGWednesday, November 26, 2025 at 5:00:00 AM
  • The introduction of DE-VAE, an uncertainty-aware variational autoencoder, aims to enhance parametric and invertible projections of multidimensional data by utilizing differential entropy. This method addresses the limitations of existing autoencoders, particularly in handling out-of-distribution samples, and demonstrates its effectiveness through evaluations on well-known datasets using UMAP and t-SNE as benchmarks.
  • This development is significant as it allows for improved data embedding and synthesis, which can facilitate advancements in various fields, including machine learning and data analysis. By enhancing the ability to manage uncertainty in projections, DE-VAE could lead to more robust applications in real-world scenarios where data variability is a challenge.
  • The focus on uncertainty in machine learning models is increasingly relevant, particularly as researchers seek to improve the reliability of generative models and their outputs. The integration of differential entropy into variational autoencoders reflects a broader trend towards addressing the complexities of data representation and uncertainty, paralleling efforts in other domains such as large language models, where similar challenges of accuracy and reliability are being tackled.
