Knowledge Sharing based Lightweight Transformer for Construction Safety Accident Prevention

NamGyu Jung, SaeBom Lee, Chang Choi

ACM/SIGAPP Symposium on Applied Computing (SAC) 2024

We present a lightweight transformer model with shared embeddings between encoders and decoders, designed to enhance efficiency and address expression imbalance in construction safety prediction. The model reduces parameters by 48% compared to conventional transformers and improves performance by 4% over LSTM, enabling effective correlation analysis and deployment in edge computing environments.

Kiosk Recommend System Based On Self-Supervised Representation Learning of User Behaviors in Offline Retail

NamGyu Jung, Van Thuy Hoang, O-Joun Lee, Chang Choi

IEEE Internet of Things Journal 2024

We propose a context-aware hyper-personalized recommendation system for kiosk IoT devices, addressing data imbalance across domains with an efficient self-supervised learning method. The system demonstrated a 20% improvement in performance metrics and an additional 0.8% gain with self-supervised learning, ensuring high-quality recommendations and optimal resource usage.

News Category Classification via Multimodal Fusion Method

NamGyu Jung, JunHo Yoon, SaeBom Lee, PanKoo Kim, KiHo Lim, Chang Choi

International Conference on Research in Adaptive and Convergent System (RACS) 2023

We propose a multimodal fusion approach for news categorization, combining image and text data to enhance classification accuracy in digital journalism. Among the evaluated methods, early fusion achieved the best performance with 78.13% accuracy and an F1 score of 0.7810, demonstrating the effectiveness of integrating modalities.
