Diffusion$^2$: Dynamic 3D Content Generation via Score Composition of Orthogonal Diffusion Models

1 code implementation2 Apr 2024 Zeyu Yang, Zijie Pan, Chun Gu, Li Zhang

Recent advancements in 3D generation are predominantly propelled by improvements in 3D-aware image diffusion models which are pretrained on Internet-scale image data and fine-tuned on massive 3D data, offering the capability of producing highly consistent multi-view images.

$\textbf{S}^2$IP-LLM: Semantic Space Informed Prompt Learning with LLM for Time Series Forecasting

no code implementations9 Mar 2024 Zijie Pan, Yushan Jiang, Sahil Garg, Anderson Schneider, Yuriy Nevmyvaka, Dongjin Song

To this end, we propose Semantic Space Informed Prompt learning with LLM ($S^2$IP-LLM) to align the pre-trained semantic space with time series embeddings space and perform time series forecasting based on learned prompts from the joint space.

Structural Knowledge Informed Continual Multivariate Time Series Forecasting

no code implementations20 Feb 2024 Zijie Pan, Yushan Jiang, Dongjin Song, Sahil Garg, Kashif Rasul, Anderson Schneider, Yuriy Nevmyvaka

To address this issue, we propose a novel Structural Knowledge Informed Continual Learning (SKI-CL) framework to perform MTS forecasting within a continual learning paradigm, which leverages structural knowledge to steer the forecasting model toward identifying and adapting to different regimes, and selects representative MTS samples from each regime for memory replay.

Fast Dynamic 3D Object Generation from a Single-view Video

no code implementations16 Jan 2024 Zijie Pan, Zeyu Yang, Xiatian Zhu, Li Zhang

Generating dynamic 3D object from a single-view video is challenging due to the lack of 4D labeled data.

Enhancing High-Resolution 3D Generation through Pixel-wise Gradient Clipping

1 code implementation19 Oct 2023 Zijie Pan, Jiachen Lu, Xiatian Zhu, Li Zhang

In this framework, a significant challenge arises: To compute gradients for individual image pixels, it is necessary to backpropagate gradients from the designated latent space through the frozen components of the image model, such as the VAE encoder used within LDM.

Real-time Photorealistic Dynamic Scene Representation and Rendering with 4D Gaussian Splatting

1 code implementation16 Oct 2023 Zeyu Yang, Hongye Yang, Zijie Pan, Li Zhang

Reconstructing dynamic 3D scenes from 2D images and generating diverse views over time is challenging due to scene complexity and temporal dynamics.
