Tackling Few-Shot Segmentation in Remote Sensing via Inpainting Diffusion Model

1 code implementation5 Mar 2025 Steve Andreas Immanuel, Woojin Cho, Junhyuk Heo, Darongsae Kwon

In the few-shot segmentation task, models are typically trained on base classes with abundant annotations and later adapted to novel classes with limited examples.

MaD-Scientist: AI-based Scientist solving Convection-Diffusion-Reaction Equations Using Massive PINN-Based Prior Data

no code implementations9 Oct 2024 Mingu Kang, Dongseok Lee, Woojin Cho, Jaehyeon Park, Kookjin Lee, Anthony Gruber, Youngjoon Hong, Noseong Park

Large language models (LLMs), like ChatGPT, have shown that even trained with noisy prior data, they can generalize effectively to new tasks through in-context learning (ICL) and pre-training techniques.

FastLRNR and Sparse Physics Informed Backpropagation

no code implementations5 Oct 2024 Woojin Cho, Kookjin Lee, Noseong Park, Donsub Rim, Gerrit Welper

We introduce Sparse Physics Informed Backpropagation (SPInProp), a new class of methods for accelerating backpropagation for a specialized neural network architecture called Low Rank Neural Representation (LRNR).

Dense Hand-Object(HO) GraspNet with Full Grasping Taxonomy and Dynamics

no code implementations6 Sep 2024 Woojin Cho, Jihyun Lee, Minjae Yi, Minje Kim, Taeyun Woo, Donghwan Kim, Taewook Ha, Hyokeun Lee, Je-Hwan Ryu, Woontack Woo, Tae-Kyun Kim

Accurate hand and object 3D meshes are obtained by fitting the hand parametric model (MANO) and the hand implicit function (HALO) to multi-view RGBD frames, with the MoCap system only for objects.

Parameterized Physics-informed Neural Networks for Parameterized PDEs

no code implementations18 Aug 2024 Woojin Cho, Minju Jo, Haksoo Lim, Kookjin Lee, Dongeun Lee, Sanghyun Hong, Noseong Park

Complex physical systems are often described by partial differential equations (PDEs) that depend on parameters such as the Reynolds number in fluid mechanics.

Learning Flexible Body Collision Dynamics with Hierarchical Contact Mesh Transformer

1 code implementation19 Dec 2023 Youn-Yeol Yu, Jeongwhan Choi, Woojin Cho, Kookjin Lee, Nayong Kim, Kiseok Chang, Chang-Seung Woo, Ilho Kim, Seok-Woo Lee, Joon-Young Yang, Sooyoung Yoon, Noseong Park

These methods are typically designed to i) reduce the computational cost in solving physical dynamics and/or ii) propose techniques to enhance the solution accuracy in fluid and rigid body dynamics.
