    (Submitted) Regression-based Physics Informed Neural Networks (Reg-PINNs) for Magnetopause Tracking
    International Conference on Scientific Computing and Machine Learning 2025 (SCML2025)
    Previous research in the scientific field has utilized statistical empirical models and machine learning to address fitting challenges. While empirical models have the advantage of numerical generalization, they often sacrifice accuracy. However, conventional machine learning methods can achieve high precision but may lack the desired generalization. The article introduces a Regression-based Physics Informed Neural Networks (Reg-PINNs), which embeds physics-inspired empirical models into the neural network’s loss function, thereby combining the benefits of generalization and high accuracy. The study validates the proposed method using the magnetopause boundary location as the target and explores the feasibility of methods including Shue et al. [1998], a data overfitting model, a fully-connected networks, Reg-PINNs with Shue’s model, and Reg-PINNs with the overfitting model. Compared to Shue’s model, this technique achieves approximately a 30% reduction in RMSE, presenting a proof-of-concept improved solution for the scientific community.

    Automatic Emergency Dust-Free solution on-board International Space Station with Bi-GRU (AED-ISS)
    AI Space Challenge
    With rising concerns about PM2.5 and PM0.3 particulate matter, which pose threats to both the environment and human health, as well as to instruments on the International Space Station (ISS), our team aims to relate particulate concentrations to factors like magnetic fields, humidity, acceleration, temperature, pressure, and CO2 concentration. Our goal is to develop an early warning system (EWS) using Bi-GRU algorithms to predict particulate levels, providing astronauts with reaction time to protect instruments and increase measurement accuracy. This model could also serve as a remote-sensing smoke alarm prototype.

    Utilizing Pop-Up Platform on the CubeSat to Achieve Commercial Activities in the Universe (UCCU)
    International Conference on Astronautics and Space Exploration (iCASE)
    The mission aims to develop a CubeSat that records videos of messages and objects sent from Earth. These messages can be advertisements, personal messages, or any sponsor-desired objects. The project seeks to showcase the business potential of space advertising and encourage industry-academia collaboration in Taiwan. Key technologies include a pop-up structure, camera design for clear capture of objects and Earth, and radiation-proof OLED displays. An undergraduate team will develop the CubeSat, offering a flexible and affordable space experience. The project also aims to reduce costs in scientific research by integrating commercial objectives.

    Regression-based Physics Informed Neural Networks for Magnetopause Tracking
    In this study, we propose a Regression-based Physics-Informed Neural Networks (Reg-PINNs) that combines physics-based numerical computation with vanilla machine learning. This new generation of PINNs overcomes the limitations of previous methods restricted to solving ordinary and partial differential equations by incorporating conventional empirical models to aid the convergence and enhance the generalization capability of the neural network. Compared to Shue et al. [1998], our model achieves a reduction of approximately 30% in root mean square error.

    Comparing Kalman Filter with Recurrent-based machine learning on Satellite Attitude Determination
    his study utilizes attitude data (position and velocity) from the IDEASSat (INSPIRESat-2) satellite and applies the GRU (Gated Recurrent Unit) machine learning algorithm to predict these parameters. The predicted values are compared with those obtained from a Kalman filter, and results indicate that the Bi-GRU algorithm performs slightly better.

    Benchmarks on ImageNet and MNIST with self-constructed Neural Networks
    With the increasing attention on pure Data-Driven Methods, the Fourier Neural Operator (FNO) shows a great promising prospect in applications such as solving partial differential equations and zero-shot super-resolution in addition to the image classification problem. In this work, we thoroughly investigate the mechanism of FNO and independently implement it via Tensorflow. The benchmarks of the standard MNIST image classification problem against FCN, CNN, and ResNet shows a higher accuracy with the price of longer training (and inferencing) time.
