How can diffusion models be combined with 3D reconstruction to achieve better performance? 


Best insight from top research papers

Diffusion models can be combined with 3D reconstruction to achieve better performance by using them as priors for reconstruction tasks. By leveraging diffusion models, it is possible to address inverse problems in an unsupervised way by constraining the sampling process based on a conditioning input. This approach allows for the inpainting of self-occluded areas and unknown components, resulting in more accurate and consistent reconstruction. Additionally, diffusion models can be trained on high-quality datasets to learn the structural distribution of the target object, enabling the generation of high-resolution images even in the presence of unseen factors. These models can be used to condition the generation process and produce high-resolution reconstruction results without the need for re-training.

Diffusion models can be combined with 3D reconstruction by pre-training the diffusion model to learn the structural distribution of biological tissue from lateral microscopic images, and then using low-axial-resolution microscopy images to condition the generation process and generate high-axial-resolution reconstruction results. This allows for isotropic reconstruction without requiring re-training.

Can trained latent diffusion models be adapted using 3D data?5 answersTrained latent diffusion models can be adapted using 3D data. A novel approach called the 3D autodecoder framework embeds properties learned from the target dataset in the latent space, allowing for the generation of static and articulated 3D assets with view-consistent appearance and geometry. Additionally, Latent Diffusion Models (LDMs) enable the scaling of denoising diffusion probabilistic models (DDPMs) to high-resolution 3D medical data, making them suitable for out-of-distribution (OOD) detection on 3D datasets. Furthermore, a diffusion-based framework called Make-A-Volume leverages 2D backbones and introduces volumetric layers to enable cross-modality 3D medical image synthesis, achieving superior synthesis results with volumetric consistency.
What are diffusion models?5 answersDiffusion models are a class of generative models that have been widely used for image processing tasks such as text conditional generation and inpainting. These models can also be adapted to make predictions and provide uncertainty quantification for chaotic dynamical systems. Diffusion models implicitly represent knowledge about outliers and extreme events, but querying that knowledge through conditional sampling or measuring probabilities is challenging. Existing methods for conditional sampling at inference time are insufficient to match the distribution statistics or compute the probability of chosen events. To address this, a probabilistic approximation scheme for the conditional score function has been developed, which converges to the true distribution as the noise level decreases. This scheme enables conditional sampling on nonlinear user-defined events and matches data statistics even when sampling from the tails of the distribution. Diffusion models have also been explored as a unified representation learner, capable of addressing both generative and discriminative tasks simultaneously. These models have shown promising results in tasks such as image generation, denoising, inpainting, super-resolution, manipulation, and classification. Diffusion models have advantages over other generative models, such as easier training and flexibility, and have been applied to various fields including image generation, image enhancement, image restoration, and text-to-image. In recent years, diffusion models have been extended to time series applications and have been used for time series forecasting, imputation, and generation. These models have shown strong performance in generating samples that resemble observed data and have the potential for further research and development.
How can diffusion models be used to design proteins?4 answersDiffusion models can be used to design proteins by combining generative and discriminative models for conditional sampling. The generative model samples plausible sequences, while the discriminative model guides the search for sequences with high fitness. This approach has been successful in protein design, leading to the development of guided diffusion models for structure with inverse folding to recover sequences. Diffusion models can reduce the complexity of protein modeling by capturing the distribution of natural protein structures in a condensed latent space. This is achieved through an equivariant protein autoencoder that embeds proteins into a latent space and uses an equivariant diffusion model to learn the distribution of the latent protein representations. These diffusion models have been shown to effectively generate novel protein backbone structures with high designability and efficiency. Additionally, diffusion models have been extended to the Riemannian manifold setting, allowing for the constrained conformational modeling of protein backbones.
Are diffusion models better than GANs?5 answersDiffusion models have shown promising results and advantages over GANs in various domains. They can address both generative and discriminative tasks simultaneously, generating high fidelity, diverse, and novel images. In the field of astronomy, diffusion models have been found to outperform GANs in terms of generating accurate images and providing reliable parameter constraints. However, when it comes to medical imaging, diffusion models have been observed to have a higher likelihood of memorizing training images, especially for small datasets. In the context of generating mixed-type tabular electronic health records (EHRs), diffusion models, specifically the TabDDPM model, have been found to outperform existing methods in terms of data quality, utility, and augmentation. Therefore, while diffusion models offer advantages over GANs in certain domains, researchers should be cautious about their limitations and consider the specific requirements of their applications.
What is diffusion model compared to GAN?4 answersDiffusion models are a type of generative model that are used for high-fidelity image generation. They have been shown to exceed the quality of Generative Adversarial Networks (GANs) in many cases. Diffusion models extract low-and-high frequency components from images and adaptively handle these components for faster processing while maintaining good generation quality. They also use a reconstruction term to boost model training convergence. Diffusion models have slower training and inference speeds compared to GANs, which has limited their use in real-time applications. However, recent advancements, such as the wavelet-based diffusion scheme, aim to reduce this speed gap and offer real-time and high-fidelity diffusion models. Overall, diffusion models provide a promising alternative to GANs for accurate image generation.
How can diffusion models be used to improve the performance of language models?5 answersDiffusion models can be used to improve the performance of language models in several ways. Firstly, diffusion models have advantages over autoregressive models in terms of parallel generation, text interpolation, token-level controls, and robustness. They can handle discrete data better by strategically soft-masking the text and directly predicting the categorical distribution in every diffusion step. Additionally, algorithmic improvements and scaling laws have been introduced to train diffusion models more effectively, leading to better likelihoods on standard language modeling benchmarks. For example, Plaid 1B, a large diffusion language model, has been developed and outperforms GPT-2 124M in likelihood on benchmark datasets. These advancements in diffusion models offer promising directions for improving the performance of language models in natural language processing.
