Latest 100 papers on diffusion model: Aug. 25, 2025
Diffusion models continue to redefine the boundaries of what’s possible in AI, evolving from remarkable image generators to powerful engines for understanding and creating complex data across diverse domains. Recent research highlights a surge of innovation, pushing these models into new frontiers, from refining 3D environments and human-AI interaction to revolutionizing fields like materials science and medical imaging.
The Big Idea(s) & Core Innovations
At the heart of these advancements is the growing sophistication of how diffusion models handle intricate data and real-world constraints. A significant theme is the move towards more precise control and higher fidelity in generative tasks, especially in 3D. For instance, Text-to-3D Generation using Jensen-Shannon Score Distillation by Khoi Do and Binh-Son Hua from Trinity College Dublin enhances 3D asset diversity and optimization stability by replacing the Kullback–Leibler divergence with Jensen-Shannon divergence. Building on this, Collaborative Multi-Modal Coding for High-Quality 3D Generation by Z. He et al. (3DTopia, UC Berkeley, Tsinghua University, etc.) introduces a novel framework for creating detailed 3D models by integrating multiple modalities like text, images, and geometry. This multi-modal synergy is further explored in MoVieDrive: Multi-Modal Multi-View Urban Scene Video Generation by Guile Wu et al. from Huawei Noah’s Ark Lab and University of Toronto, which synthesizes urban scene videos from RGB, depth, and semantic maps, crucial for autonomous driving.
Solving persistent challenges in 3D editing and reconstruction is also a major focus. Localized Gaussian Splatting Editing with Contextual Awareness by Hanyuan Xiao et al. (University of Southern California, HKUST) introduces an illumination-aware pipeline for text-guided 3D scene editing, ensuring global lighting consistency. For difficult reconstruction scenarios, GSFix3D: Diffusion-Guided Repair of Novel Views in Gaussian Splatting by Jiaxin Wei et al. (Technical University of Munich, ETH Zurich) uses diffusion models to repair under-constrained regions in 3D Gaussian Splatting, significantly improving visual fidelity from extreme viewpoints. Another breakthrough, TINKER: Diffusion’s Gift to 3D—Multi-View Consistent Editing From Sparse Inputs without Per-Scene Optimization by Canyu Zhao et al. (Zhejiang University), enables high-fidelity 3D editing from sparse inputs (one or two images) without per-scene fine-tuning.
The push for efficiency and better control over generative processes is evident. Squeezed Diffusion Models by Jyotirmai Singh et al. from Stanford University introduces anisotropic noise scaling to enhance generative quality without altering model architecture, drawing inspiration from quantum mechanics. Meanwhile, Disentanglement in T-space for Faster and Distributed Training of Diffusion Models with Fewer Latent-states by Samarth Gupta et al. from Amazon challenges the notion that many latent states are needed, achieving faster convergence and distributed training with fewer states.
Beyond visual generation, diffusion models are proving adept at solving complex inverse problems and enabling real-world applications. For example, A Diffusion Model Framework for Unsupervised Neural Combinatorial Optimization by Sebastian Sanokowski et al. (Johannes Kepler University, ELLIS Unit Linz) adapts diffusion models for data-free approximation of discrete distributions in combinatorial optimization. In medical imaging, Pathology-Informed Latent Diffusion Model for Anomaly Detection in Lymph Node Metastasis introduces AnoPILaD for unsupervised anomaly detection using semantic guidance from vision-language models, while 3D Cardiac Anatomy Generation Using Mesh Latent Diffusion Models by Jolanta Mozyrska et al. from the University of Oxford generates realistic 3D cardiac meshes for medical research. Notably, Cross-Modality Controlled Molecule Generation with Diffusion Language Model by Yunzhe Zhang et al. from Brandeis University shows how diffusion language models can flexibly generate molecules under diverse constraints, crucial for drug discovery.
Safety and alignment with human intent are also central themes. CopyrightShield: Enhancing Diffusion Model Security against Copyright Infringement Attacks from Nanyang Technological University and Beihang University introduces a defense framework combining poisoned sample detection and adaptive optimization to combat copyright infringement. VideoEraser: Concept Erasure in Text-to-Video Diffusion Models by Naen Xu et al. (Zhejiang University, UCLA) offers a training-free solution for removing undesirable concepts in text-to-video generation.
