Probabilistic Implicit Scene Completion

2 code implementations ICLR 2022 Dongsu Zhang, Changwoon Choi, Inbum Park, Young Min Kim

We also demonstrate that our approach outperforms deterministic models even in less ambiguous cases with a small amount of missing data, which infers that probabilistic formulation is crucial for high-quality geometry completion on input scans exhibiting any levels of completeness.

Learning to Generate 3D Shapes with Generative Cellular Automata

no code implementations ICLR 2021 Dongsu Zhang, Changwoon Choi, Jeonghwan Kim, Young Min Kim

We formulate the shape generation process as sampling from the transition kernel of a Markov chain, where the sampling chain eventually evolves to the full shape of the learned distribution.

Spatial Semantic Embedding Network: Fast 3D Instance Segmentation with Deep Metric Learning

1 code implementation7 Jul 2020 Dongsu Zhang, Junha Chun, Sang Kyun Cha, Young Min Kim

We propose spatial semantic embedding network (SSEN), a simple, yet efficient algorithm for 3D instance segmentation using deep metric learning.

A Neural Dirichlet Process Mixture Model for Task-Free Continual Learning

1 code implementation ICLR 2020 Soochan Lee, Junsoo Ha, Dongsu Zhang, Gunhee Kim

Despite the growing interest in continual learning, most of its contemporary works have been studied in a rather restricted setting where tasks are clearly distinguishable, and task boundaries are known during training.
