Pyramid Diffusion for Fine 3D Large Scene Generation

1 code implementation20 Nov 2023 Yuheng Liu, Xinke Li, Xueting Li, Lu Qi, Chongshou Li, Ming-Hsuan Yang

Directly transferring the 2D techniques to 3D scene generation is challenging due to significant resolution reduction and the scarcity of comprehensive real-world 3D scene datasets.

An Exponential Factorization Machine with Percentage Error Minimization to Retail Sales Forecasting

no code implementations22 Sep 2020 Chongshou Li, Brenda Cheang, Zhixing Luo, Andrew Lim

The EFM model is significantly different from the original Factorization Machines (FM) from two-fold: (1) the attribute-level formulation for explanatory variables and (2) exponential formulation for the positive response variable.

Revisiting Modified Greedy Algorithm for Monotone Submodular Maximization with a Knapsack Constraint

no code implementations12 Aug 2020 Jing Tang, Xueyan Tang, Andrew Lim, Kai Han, Chongshou Li, Junsong Yuan

Second, we enhance the modified greedy algorithm to derive a data-dependent upper bound on the optimum.

Campus3D: A Photogrammetry Point Cloud Benchmark for Hierarchical Understanding of Outdoor Scene

1 code implementation11 Aug 2020 Xinke Li, Chongshou Li, Zekun Tong, Andrew Lim, Junsong Yuan, Yuwei Wu, Jing Tang, Raymond Huang

Based on it, we formulate a hierarchical learning problem for 3D point cloud segmentation and propose a measurement evaluating consistency across various hierarchies.

WeText: Scene Text Detection under Weak Supervision

no code implementations ICCV 2017 Shangxuan Tian, Shijian Lu, Chongshou Li

With a "light" supervised model trained on a small fully annotated dataset, we explore semi-supervised and weakly supervised learning on a large unannotated dataset and a large weakly annotated dataset, respectively.
