Profile
I am Justin, who graduated from the department of Computer Science Engineering at National Sun Yat-sen University. I am friendly, optimistic, and willing to learn new knowledge.
As a software engineer, I am proficient in using Python, C/C++, and Java, and have an understanding of Git, which I have utilized for collaborative development projects with team members. Additionally, I have experience with Azure CI/CD, Docker, and Kubernetes (K8s), which has allowed me to proficiently manage and deploy applications to the cloud. These technologies has enabled me to streamline the software development process and enhance the overall quality of the projects.
I have served as the co-PI of a project under the Ministry of Science and Technology, honing my skills in coordination and teamwork. During my university studies, I also acted as a teaching assistant for courses in Artificial Intelligence, Algorithms, and Individual Study, helping instructors address students' inquiries.
My research focus is on neural network training algorithms to enhance the accuracy of deep learning models. I have proposed a novel optimization algorithm in my thesis that combines meta-heuristic algorithms and gradient-based optimization techniques, effectively improving the accuracy of deep learning models. The effectiveness of the proposed algorithm is demonstrated through experiments on various types of datasets and neural network models.

Thesis
An Effective Optimizer based on Global and Local Searched Experiences for Neural Network Training.
This thesis proposes a novel hybrid optimizer, GLAdam, which combines the benefits of meta-heuristic and gradient-based methods. GLAdam calculates the update direction by incorporating both global and local searched experiences, leading to an improved optimization process. The performance of GLAdam was evaluated through time series numerical forecasting and image classification experiments, demonstrating its effectiveness in training machine learning models.
Conference paper
ACM ICEA, “An Effective Optimizer based on Global and Local Searched Experiences for Short-term Electricity Consumption Forecasting”, Korea, 2020
This study presents a novel optimization algorithm, GLAdam, aimed at addressing the limitations of conventional gradient-based optimization methods. GLAdam incorporates a heuristic mechanism that leverages past search experiences, resulting in a more efficient exploration-exploitation trade-off during the optimization process. The results of experiments on time series numerical forecasting and image classification datasets show that GLAdam outperforms popular optimization algorithms such as Adagrad, RMSprop, and Adam, with an improvement in accuracy of 5.37% compared to the best performing algorithm.
ACM ICEA, “An Effective Multi-Swarm Algorithm for Optimizing Hyperparameters of DNN”, Korea, 2020
This study proposes an improved Multi-Swarm Particle Swarm Optimization (MSPSO) algorithm for optimizing hyperparameters of Deep Neural Networks (DNNs). The proposed algorithm outperforms traditional methods and was evaluated on Taipei passenger data, demonstrating improved accuracy in predicting the number of passengers for Taipei metro stations compared to other machine learning algorithms, DNN, and PSO with DNN.
