Diverse and Stable 2D Diffusion Guided Text to 3D Generation with Noise Recalibration

AAAI 2024technical

In recent years, following the success of text guided image generation, text guided 3D generation has gained increasing attention among researchers. Dreamfusion is a notable approach that enhances generation quality by utilizing 2D text guided diffusion models and introducing SDS loss, a technique f…

Variance-Insensitive and Target-Preserving Mask Refinement for Interactive Image Segmentation

AAAI 2024technical

Point-based interactive image segmentation can ease the burden of mask annotation in applications such as semantic segmentation and image editing. However, fully extracting the target mask with limited user inputs remains challenging. We introduce a novel method, Variance-Insensitive and Target-Pres…

WaveNet: Tackling Non-stationary Graph Signals via Graph Spectral Wavelets

AAAI 2024technical

In the existing spectral GNNs, polynomial-based methods occupy the mainstream in designing a filter through the Laplacian matrix. However, polynomial combinations factored by the Laplacian matrix naturally have limitations in message passing (e.g., over-smoothing). Furthermore, most existing spectra…

Reward Imputation with Sketching for Contextual Batched Bandits

NeurIPS 2023poster

Contextual batched bandit (CBB) is a setting where a batch of rewards is observed from the environment at the end of each episode, but the rewards of the non-executed actions are unobserved, resulting in partial-information feedback. Existing approaches for CBB often ignore the rewards of the non-ex…
