Historical Consensus: Preventing Posterior Collapse via Iterative Selection of Gaussian Mixture Priors

This paper introduces Historical Consensus Training, an iterative method that eliminates posterior collapse in Variational Autoencoders by progressively refining Gaussian Mixture Model priors to create a stable parameter barrier that prevents the degeneration of latent variables, achieving robust representations without relying on specific architectural constraints or hyperparameter tuning.

Safe RLHF Beyond Expectation: Stochastic Dominance for Universal Spectral Risk Control

This paper proposes Risk-sensitive Alignment via Dominance (RAD), a novel Safe RLHF framework that replaces traditional expected cost constraints with First-Order Stochastic Dominance constraints within an Optimal Transport framework to universally control spectral risk measures, thereby achieving superior robustness against tail risks and out-of-distribution failures while maintaining helpfulness.

Does AI See like Art Historians? Interpreting How Vision Language Models Recognize Artistic Style

Through an interdisciplinary collaboration between computer scientists and art historians, this paper employs latent-space decomposition and quantitative analysis to reveal that Vision Language Models predict artistic styles using concepts that are largely coherent and relevant to human experts, often aligning with art historical reasoning even when utilizing formally interpreted features.
