Deblurring 3D Gaussian Splatting

no code implementations1 Jan 2024 Byeonghyeon Lee, Howoong Lee, Xiangyu Sun, Usman Ali, Eunbyung Park

However, it suffers from severe degradation in the rendering quality if the training images are blurry.

Compact 3D Gaussian Representation for Radiance Field

1 code implementation22 Nov 2023 Joo Chan Lee, Daniel Rho, Xiangyu Sun, Jong Hwan Ko, Eunbyung Park

On the other hand, 3D Gaussian splatting (3DGS) has recently emerged as an alternative representation that leverages a 3D Gaussisan-based representation and adopts the rasterization pipeline to render the images rather than volumetric rendering, achieving very fast rendering speed and promising image quality.

ChatPipe: Orchestrating Data Preparation Program by Optimizing Human-ChatGPT Interactions

no code implementations7 Apr 2023 Sibei Chen, Hanbing Liu, Weiting Jin, Xiangyu Sun, Xiaoyao Feng, Ju Fan, Xiaoyong Du, Nan Tang

Orchestrating a high-quality data preparation program is essential for successful machine learning (ML), but it is known to be time and effort consuming.

Learning Tree Interpretation from Object Representation for Deep Reinforcement Learning

no code implementations NeurIPS 2021 Guiliang Liu, Xiangyu Sun, Oliver Schulte, Pascal Poupart

We propose a Represent And Mimic (RAMi) framework for training 1) an identifiable latent representation to capture the independent factors of variation for the objects and 2) a mimic tree that extracts the causal impact of the latent features on DRL action values.

NTS-NOTEARS: Learning Nonparametric DBNs With Prior Knowledge

1 code implementation9 Sep 2021 Xiangyu Sun, Oliver Schulte, Guiliang Liu, Pascal Poupart

We describe NTS-NOTEARS, a score-based structure learning method for time-series data to learn dynamic Bayesian networks (DBNs) that captures nonlinear, lagged (inter-slice) and instantaneous (intra-slice) relations among variables.
