Multi-Concept Customization of Text-to-Image Diffusion [PDF]
Computer Vision and Pattern Recognition, 2022 While generative models produce high-quality images of concepts learned from a large-scale database, a user often wishes to synthesize instantiations of their own concepts (for example, their family, pets, or items).

Intercomparison of In Situ Sensors for Ground-Based Land Surface Temperature Measurements
Sensors, 2020 Land surface temperature (LST) is a key variable in the determination of land surface energy exchange processes from local to global scales. Accurate ground measurements of LST are necessary for a number of applications including validation of satellite ...

MVDream: Multi-view Diffusion for 3D Generation [PDF]
International Conference on Learning Representations, 2023 We introduce MVDream, a diffusion model that is able to generate consistent multi-view images from a given text prompt. Learning from both 2D and 3D data, a multi-view diffusion model can achieve the generalizability of 2D diffusion models and the ...

Human Motion Diffusion Model [PDF]
International Conference on Learning Representations, 2022 Natural and expressive human motion generation is the holy grail of computer animation. It is a challenging task, due to the diversity of possible motion, human perceptual sensitivity to it, and the difficulty of accurately describing it.

Training Diffusion Models with Reinforcement Learning [PDF]
International Conference on Learning Representations, 2023 Diffusion models are a class of flexible generative models trained with an approximation to the log-likelihood objective. However, most use cases of diffusion models are not concerned with likelihoods, but instead with downstream objectives such as human-

Artificial intelligence-based locoregional markers of brain peritumoral microenvironment
Scientific Reports, 2023 In malignant primary brain tumors, cancer cells infiltrate into the peritumoral brain structures which results in inevitable recurrence. Quantitative assessment of infiltrative heterogeneity in the peritumoral region, the area where biopsy or resection ...

A new reference-quality precipitation gauge wind shield [PDF]
Atmospheric Measurement Techniques, 2023 Gauge-based precipitation measurements suffer from undercatch due to the effects of wind, with solid-precipitation measurements especially susceptible to such errors.
