RBF-PINN: Non-Fourier Positional Embedding in Physics-Informed Neural Networks

1 code implementation13 Feb 2024 Chengxi Zeng, Tilo Burghardt, Alberto M Gambaruto

While many recent Physics-Informed Neural Networks (PINNs) variants have had considerable success in solving Partial Differential Equations, the empirical benefits of feature mapping drawn from the broader Neural Representations research have been largely overlooked.

Training dynamics in Physics-Informed Neural Networks with feature mapping

1 code implementation10 Feb 2024 Chengxi Zeng, Tilo Burghardt, Alberto M Gambaruto

Physics-Informed Neural Networks (PINNs) have emerged as an iconic machine learning approach for solving Partial Differential Equations (PDEs).

Video-TransUNet: Temporally Blended Vision Transformer for CT VFSS Instance Segmentation

2 code implementations17 Aug 2022 Chengxi Zeng, Xinyu Yang, Majid Mirmehdi, Alberto M Gambaruto, Tilo Burghardt

Our findings suggest that the proposed model can indeed enhance the TransUNet architecture via exploiting temporal information and improving segmentation performance by a significant margin.
