Bespoke Nanoparticle Synthesis and Chemical Knowledge Discovery Via Autonomous Experimentations

3 code implementations1 Sep 2023 Hyuk Jun Yoo, Nayeon Kim, Heeseung Lee, Daeho Kim, Leslie Tiong Ching Ow, Hyobin Nam, Chansoo Kim, Seung Yong Lee, Kwan-Young Lee, Donghun Kim, Sang Soo Han

The optimization of nanomaterial synthesis using numerous synthetic variables is considered to be extremely laborious task because the conventional combinatorial explorations are prohibitively expensive.

Robustness of SAM: Segment Anything Under Corruptions and Beyond

no code implementations13 Jun 2023 Yu Qiao, Chaoning Zhang, Taegoo Kang, Donghun Kim, Chenshuang Zhang, Choong Seon Hong

Following by interpreting the effects of synthetic corruption as style changes, we proceed to conduct a comprehensive evaluation for its robustness against 15 types of common corruption.

Predicting failure characteristics of structural materials via deep learning based on nondestructive void topology

1 code implementation17 May 2022 Leslie Ching Ow Tiong, Gunjick Lee, Seok Su Sohn, Donghun Kim

The combined PH and DML processing of 3D X-CT data is our unique approach enabling reliable failure predictions at the time of material examination based on void topology progressions, and the method can be extended to various nondestructive failure tests for practical use.

Identification of Crystal Symmetry from Noisy Diffraction Patterns by A Shape Analysis and Deep Learning

1 code implementation26 May 2020 Leslie Ching Ow Tiong, Jeongrae Kim, Sang Soo Han, Donghun Kim

On the other hand, the DL-based identification of crystal symmetry suffers from a drastic drop in accuracy for problems involving classification into tens or hundreds of symmetry classes (e. g., up to 230 space groups), severely limiting its practical usage.
