Make-It-3D: High-Fidelity 3D Creation from A Single Image with Diffusion Prior [PDF]
IEEE International Conference on Computer Vision, 2023 In this work, we investigate the problem of creating high-fidelity 3D content from only a single image. This is inherently challenging: it essentially involves estimating the underlying 3D geometry while simultaneously hallucinating unseen textures.

Speak, Read and Prompt: High-Fidelity Text-to-Speech with Minimal Supervision [PDF]
Transactions of the Association for Computational Linguistics, 2023 We introduce SPEAR-TTS, a multi-speaker text-to-speech (TTS) system that can be trained with minimal supervision. By combining two types of discrete speech representations, we cast TTS as a composition of two sequence-to-sequence tasks: from text to high-
