  Mixture-of-Experts (MoE), popularized by large language models, is a promising paradigm for scaling visual generative models. However, conventional token-wise MoE routes tokens independently within a homogeneous expert pool and regularizes expert usage toward uniformity, making it poorly matched to …

• You Can't Have It Both Ways: Concept Entanglement Limits Diffusion Model Unlearning

  Yian Wang, Ali Ebrahimpour-Boroojeny, Hari Sundaram, Varun Chandrasekaran · 29 September 2026 · Domain Adaptation and Few-Shot Learning

  Concept unlearning in text-to-image diffusion models aims to suppress a target concept (e.g., \texttt{horse}) while preserving related but distinct content (e.g., \texttt{donkey}), yet existing methods either leak under indirect prompts or visibly degrade other concepts. We show that these failure m…

• FeatMark: Feature-level Watermark Protection against Mimicry Attacks with Diffusion Models

Yet training these models involves estimating high-dimensional score functions, a task that in principle suffers from the curse of dimensionality. It is therefore important to understand how low-dimensional structure in the ta…

• Robustness of Diffusion Models under Distribution Shift

  Wei Luo, Neil K. Chada, Shijie Zhang, Lu Yu · 24 September 2026 · Markov Chains and Monte Carlo Methods

  Score-based diffusion models are increasingly considered in settings where the underlying data distribution may differ from the training distribution, yet existing theoretical guarantees largely focus on the no-shift setting. In this work, we study robust score estimation under Wasserstein perturbat…

• Discrete Diffusion Models via Evolving Variational Autoregressive Networks

  Kewen Pan, Ying Tang · 24 September 2026 · Advanced Mathematical Modeling in Engineering

• Double Descent and Malign Overfitting in Diffusion Models

  Rapha\"el Urfin, Tony Bonnaire, Giulio Biroli, Marc M\'ezard · 23 September 2026 · Advanced Mathematical Modeling in Engineering

  Conventional wisdom in deep learning holds that overparameterization---having more parameters $p$ than training samples $n$---is benign: larger models generalize better and, even without regularization, interpolating models generalize well, the test error following a double-descent curve. One might …

• Mean Velocity Matching: Rethinking Generative Dynamics in Diffusion Models

  Discrete diffusion models now match autoregressive language models on several benchmarks, while the question of how best to train them has received far less attention: the optimizer is inherited from one paper to the next and never compared. New optimizers, meanwhile, are validated almost exclusivel…

• Leveraging Inference-Time Compute for Diffusion Models via Global Scheduling of Denoising Trajectories

  Yuan Cao, Yifu Tang, Hangqi Li, Zeyu Zheng · 22 September 2026 · Advanced Mathematical Modeling in Engineering

  Diffusion models generate a sample by traversing a denoising trajectory, a sequence of stochastic noise-reduction steps that transforms pure noise into a draw from a target distribution. At deployment time, additional computation can improve sample quality without retraining: at each step, the sampl…

• Monotone-Constrained Diffusion Models for Long-Horizon Production Forecasting

  Temesgen Mikael Abraha, Yves Lucet · 22 September 2026 · Forecasting Techniques and Applications

  Forecasting a long horizon from only the first observations of a sequence is ill-posed: many trajectories are consistent with the same short history. We study this problem in oil and gas production forecasting, where forecasts made after roughly the first fifth of a well's producing life drive devel…
