Cross-Modal Contextualized Diffusion Models for Text-Guided Visual Generation and Editing

ICLR 2024poster

Conditional diffusion models have exhibited superior performance in high-fidelity text-guided visual generation and editing. Nevertheless, prevailing text-guided visual diffusion models primarily focus on incorporating text-visual relationships exclusively into the reverse process, often disregardin…

Retrieval-Augmented Diffusion Models for Time Series Forecasting

NeurIPS 2024poster

While time series diffusion models have received considerable focus from many recent works, the performance of existing models remains highly unstable. Factors limiting time series diffusion models include insufficient time series datasets and the absence of guidance. To address these limitations, w…

Structure-Guided Adversarial Training of Diffusion Models

CVPR 2024poster

Diffusion models have demonstrated exceptional efficacy in various generative applications. While existing models focus on minimizing a weighted sum of denoising score matching losses for data distribution modeling their training primarily emphasizes instance-level optimization overlooking valuable…

EV-Eye: Rethinking High-frequency Eye Tracking through the Lenses of Event Cameras

NeurIPS 2023poster

In this paper, we present EV-Eye, a first-of-its-kind large scale multimodal eye tracking dataset aimed at inspiring research on high-frequency eye/gaze tracking. EV-Eye utilizes an emerging bio-inspired event camera to capture independent pixel-level intensity changes induced by eye movements, achi…

Improving Diffusion-Based Image Synthesis with Context Prediction

NeurIPS 2023poster

Diffusion models are a new class of generative models, and have dramatically promoted image generation with unprecedented quality and diversity. Existing diffusion models mainly try to reconstruct input image from a corrupted one with a pixel-wise or feature-wise constraint along spatial axes. Howev…
