This paper introduces Multivariate Fields of Experts, a new image prior framework that generalizes existing methods using multivariate potential functions to achieve fast, interpretable, and theoretically guaranteed convergence in various inverse problems, outperforming univariate models while approaching deep learning performance with significantly fewer parameters and data.
This paper provides a theoretical characterization of the Expectation-Maximization algorithm's behavior in overspecified two-component mixed linear regression, establishing that unbalanced initial mixing weights yield linear convergence and optimal statistical accuracy, whereas balanced initial weights result in sublinear convergence and degraded accuracy.
This paper introduces Kernel VICReg, a novel self-supervised learning framework that extends the VICReg objective into a Reproducing Kernel Hilbert Space to capture nonlinear dependencies and improve representation learning performance on datasets with complex geometric structures.

This paper demonstrates that deep neural network ensembles enable accurate, real-time quantum parameter estimation with well-calibrated uncertainty quantification and drift detection, offering a faster alternative to traditional Bayesian inference methods without sacrificing accuracy.
This paper introduces "Answer-Then-Check," a novel safety alignment method that enhances LLM robustness against jailbreak attacks by training models to generate direct answers internally and then critically evaluate their safety before responding, achieving superior protection with reduced over-refusal while maintaining general reasoning capabilities through the newly constructed 80K-sample ReSA dataset.

This paper proposes a computationally efficient dual-network architecture combining an auto-regressive U-Net and a CNN to predict time-dependent full-field damage evolution and key mechanical properties in concrete, thereby enabling insights into aggregate effects and optimizing mix designs for improved durability.
This paper introduces GPHDM, a novel framework that extends Gaussian Process Dynamical Models to hyperbolic manifolds to generate physically consistent, human-like robot motions by preserving the hierarchical taxonomy and temporal dynamics of movement.
This paper addresses the training-inference mismatch in diffusion language models caused by planner-based sampling strategies by deriving a new Planned Evidence Lower Bound (P-ELBO) and introducing Planner Aware Path Learning (PAPL), a simple training modification that aligns training with planned inference to achieve significant performance gains across protein, text, and code generation tasks.
The paper introduces Diffusion Alignment as Variational Expectation-Maximization (DAV), an iterative framework that alternates between test-time search for diverse, reward-aligned samples and model refinement to optimize diffusion models for downstream objectives while mitigating reward over-optimization and mode collapse.
This paper addresses the online minimization of polarization and disagreement in the Friedkin-Johnsen opinion dynamics model under incomplete information by proposing a two-stage low-rank matrix bandit algorithm that achieves a cumulative regret of through subspace estimation and linear bandit optimization.
This paper introduces Self-Speculative Masked Diffusions, a novel generative model for discrete data that leverages causal attention and integrated speculative sampling to produce non-factorized predictions, thereby achieving a roughly 2x reduction in neural network forward passes compared to standard masked diffusion models.
This paper proposes TCR-EML, an explainable-by-design model that integrates prototype layers based on known biochemical binding mechanisms into protein-language model backbones to achieve competitive TCR-pMHC binding prediction accuracy while providing interpretable rationales superior to existing black-box approaches.
This paper demonstrates that while standard decoder-only models underperform compared to encoder-only architectures in cross-modal adaptation for partial differential equations, introducing novel bidirectionality-mimicking techniques like Parallel Flipping and Sequence Doubling effectively closes this performance gap.
This paper challenges the reliability of language model micro-benchmarks by demonstrating that they often fail to consistently rank models with small performance differences, frequently requiring as many as 250 examples to achieve accuracy comparable to random sampling, thereby offering actionable guidance on the trade-off between evaluation efficiency and reliability.
CanvasMAR enhances masked autoregressive video prediction by introducing a global "canvas" prior and a motion-aware curriculum to generate high-fidelity, coherent videos with fewer sampling steps, achieving performance that rivals advanced diffusion-based methods.
This paper demonstrates that injecting external verification into synthetic data retraining can prevent model collapse and yield near-term improvements, though theoretical analysis and experiments across linear regression, VAEs, and LLMs show that long-term performance ultimately converges to the verifier's knowledge center and may plateau or decline if the verifier is imperfect.
