  Shihong Li, Juntao Xu, JinCao, Maowen Tang, Jun Huang, Jintao Li · 18 September 2026 · Reservoir Engineering and Simulation Methods

  Step distillation reduces the cost of video generation, but reusing a LoRA trained for a longer trajectory can alter its functional effect or degrade target quality. Static parameter compatibility offers one perspective on this problem; our observations show that similar measured geometry can coexis…

• Efficient Text-to-Image Generation: An Adaptive Step Schedule Controller for Diffusion Models

  Kuluhan Binici, Cihan Acar, Shivam Aggarwal, Siying Liu, Tulika Mitra · 16 September 2026 · Generative Adversarial Networks and Image Synthesis

  Text-to-image diffusion models often use a fixed number of denoising steps, balancing time costs and image quality. However, the optimal number of steps depends on the complexity of the input text prompt. We propose an adaptive diffusion controller that dynamically adjusts the number of steps to gen…

  Yifan Yuan, Xiangyu Liu, Hongming Shan, Yu Han, Yu Jiang, Hao Tan, Junping Zhang, Linlin Shen · 10 September 2026 · Generative Adversarial Networks and Image Synthesis

  Although text-to-image diffusion models generally exhibit strong prompt-following ability, we identify a persistent and previously underexplored failure pattern in which a small subset of prompts differing only in the object consistently fails to realize the same target concept under identical gener…

• SwiftExplorer: Training-free Diffusion Model Alignment with Swift Diversity Exploration

  Renye Yan, Jikang Cheng, You Wu, Bojin Huang, Wei Peng, Zongwei Wang, Ling Liang, Yimao Cai · 9 September 2026 · Generative Adversarial Networks and Image Synthesis

  Diffusion models have general generative abilities but struggle to align with specific objectives. Fine-tuning can improve alignment, yet its training cost is often prohibitive. This led to training-free methods that apply objective-guided terms in sampling to bias the generation distribution toward…

  Hiep V. Dang, Antonios Mamalakis · 4 September 2026 · Meteorological Phenomena and Simulations

  Subseasonal-to-seasonal (S2S) precipitation forecasting has substantial financial and societal impact, yet remains challenging because of weak predictive signals, high associated uncertainty, and the computational cost of operational systems, which constrains simulation fidelity. We introduce SimCas…

• Conditioning Degenerate Diffusion Models

  U\u{g}ur Ayd{\i}n, Tamer Ba\c{s}ar · 4 September 2026 · Advanced Mathematical Modeling in Engineering

  Current conditioned generative models heavily rely on score functions for guidance during training. When the generative model is a diffusion process with a singular diffusion coefficient and the underlying (conditional) densities either do not exist or are not smooth, we use causal optimal transport…
