Observation, Analysis, and Solution: Exploring Strong Lightweight Vision Transformers via Masked Image Modeling Pre-Training

1 code implementation18 Apr 2024 Jin Gao, Shubo Lin, Shaoru Wang, Yutong Kou, Zeming Li, Liang Li, Congxuan Zhang, Xiaoqin Zhang, Yizheng Wang, Weiming Hu

In this paper, we question if the extremely simple ViTs' fine-tuning performance with a small-scale architecture can also benefit from this pre-training paradigm, which is considerably less studied yet in contrast to the well-established lightweight architecture design methodology with sophisticated components introduced.

ZoomTrack: Target-aware Non-uniform Resizing for Efficient Visual Tracking

1 code implementation NeurIPS 2023 Yutong Kou, Jin Gao, Bing Li, Gang Wang, Weiming Hu, Yizheng Wang, Liang Li

To this end, we non-uniformly resize the cropped image to have a smaller input size while the resolution of the area where the target is more likely to appear is higher and vice versa.

SBSM-Pro: Support Bio-sequence Machine for Proteins

1 code implementation20 Aug 2023 Yizheng Wang, Yixiao Zhai, Yijie Ding, Quan Zou

We introduce the Support Bio-Sequence Machine for Proteins (SBSM-Pro), a model purpose-built for the classification of biological sequences.

Optimizing Carbon Storage Operations for Long-Term Safety

1 code implementation19 Apr 2023 Yizheng Wang, Markus Zechner, Gege Wen, Anthony Louis Corso, John Michael Mern, Mykel J. Kochenderfer, Jef Karel Caers

In this study, we address these issues by modeling the decision-making process for carbon storage operations as a partially observable Markov decision process (POMDP).

DCEM-PINNs: A deep complementary energy method for solid mechanics

1 code implementation3 Feb 2023 Yizheng Wang, Jia Sun, Timon Rabczuk, Yinghua Liu

The results demonstrate that DCEM outperforms DEM in terms of stress accuracy and efficiency and has an advantage in dealing with complex displacement boundary conditions, which is supported by theoretical analyses and numerical simulations.

BINN: A deep learning approach for computational mechanics problems based on boundary integral equations

no code implementations11 Jan 2023 Jia Sun, Yinghua Liu, Yizheng Wang, Zhenhan Yao, Xiaoping Zheng

The boundary integral equations are employed to transfer all the unknowns to the boundary, then the unknowns are approximated using neural networks and solved through a training process.

A POMDP Model for Safe Geological Carbon Sequestration

no code implementations25 Oct 2022 Anthony Corso, Yizheng Wang, Markus Zechner, Jef Caers, Mykel J. Kochenderfer

This POMDP model can be used as a test bed to drive the development of novel decision-making algorithms for CCS operations.

PETS-SWINF: A regression method that considers images with metadata based Neural Network for pawpularity prediction on 2021 Kaggle Competition "PetFinder.my"

no code implementations16 Jan 2022 Yizheng Wang, Yinghua Liu

In order to better adopt stray animals, scoring the pawpularity (cuteness) of stray animals is very important, but evaluating the pawpularity of animals is a very labor-intensive thing.

CENN: Conservative energy method based on neural networks with subdomains for solving variational problems involving heterogeneous and complex geometries

1 code implementation25 Sep 2021 Yizheng Wang, Jia Sun, Wei Li, Zaiyuan Lu, Yinghua Liu

The advantage of the proposed method is higher efficiency, more accurate, and less hyperparameters than the strong form PINN with subdomains.
