HiFA: High-fidelity Text-to-3D Generation with Advanced Diffusion Guidance

1 code implementation30 May 2023 Junzhe Zhu, Peiye Zhuang, Sanmi Koyejo

To address texture flickering issues in NeRFs, we introduce a kernel smoothing technique that refines importance sampling weights coarse-to-fine, ensuring accurate and thorough sampling in high-density regions.

Synthetic Power Analyses: Empirical Evaluation and Application to Cognitive Neuroimaging

no code implementations11 Oct 2022 Peiye Zhuang, Bliss Chapman, Ran Li, Oluwasanmi Koyejo

We propose synthetic power analyses; a framework for estimating statistical power at various sample sizes, and empirically explore the performance of synthetic power analysis for sample size selection in cognitive neuroscience experiments.

Enjoy Your Editing: Controllable GANs for Image Editing via Latent Space Navigation

2 code implementations ICLR 2021 Peiye Zhuang, Oluwasanmi Koyejo, Alexander G. Schwing

Controllable semantic image editing enables a user to change entire image attributes with a few clicks, e. g., gradually making a summer scene look like it was taken in winter.

EMIXER: End-to-end Multimodal X-ray Generation via Self-supervision

no code implementations10 Jul 2020 Siddharth Biswal, Peiye Zhuang, Ayis Pyrros, Nasir Siddiqui, Sanmi Koyejo, Jimeng Sun

EMIXER is an conditional generative adversarial model by 1) generating an image based on a label, 2) encoding the image to a hidden embedding, 3) producing the corresponding text via a hierarchical decoder from the image embedding, and 4) a joint discriminator for assessing both the image and the corresponding text.

Data Augmentation Image Classification

FMRI data augmentation via synthesis

no code implementations13 Jul 2019 Peiye Zhuang, Alexander G. Schwing, Sanmi Koyejo

Thus, our results suggest that data augmentation via synthesis is a promising approach to address the limited availability of fMRI data, and to improve the quality of predictive fMRI models.
