Spatio-Temporal Proximity-Aware Dual-Path Model for Panoramic Activity Recognition

no code implementations21 Mar 2024 Sumin Lee, Yooseung Wang, Sangmin Woo, Changick Kim

Panoramic Activity Recognition (PAR) seeks to identify diverse human activities across different scales, from individual actions to social group and global activities in crowded panoramic scenes.

Deep Generative Model-based Synthesis of Four-bar Linkage Mechanisms with Target Conditions

1 code implementation22 Feb 2024 Sumin Lee, Jihoon Kim, Namwoo Kang

The proposed model is based on a conditional generative adversarial network (cGAN) with modifications for mechanism synthesis, which is trained to learn the relationship between the requirements of a mechanism with respect to linkage lengths.

Explore-And-Match: Bridging Proposal-Based and Proposal-Free With Transformer for Sentence Grounding in Videos

1 code implementation25 Jan 2022 Sangmin Woo, Jinyoung Park, Inyong Koo, Sumin Lee, Minki Jeong, Changick Kim

To our surprise, we found that training schedule shows divide-and-conquer-like pattern: time segments are first diversified regardless of the target, then coupled with each target, and fine-tuned to the target again.

Learning to Discriminate Information for Online Action Detection: Analysis and Application

no code implementations8 Sep 2021 Sumin Lee, Hyunjun Eun, Jinyoung Moon, Seokeon Choi, Yoonhyung Kim, Chanho Jung, Changick Kim

To overcome this problem, we propose a novel recurrent unit, named Information Discrimination Unit (IDU), which explicitly discriminates the information relevancy between an ongoing action and others to decide whether to accumulate the input information.
