Vision-Language Models for Infrared Industrial Sensing in Additive Manufacturing Scene Description
Nazanin Mahjourian, Vinh Nguyen
Many manufacturing environments operate in low-light conditions or within enclosed machines where conventional vision systems struggle. Infrared cameras provide complementary advan…
From Prompting to Preference Optimization: A Comparative Study of LLM-based Automated Essay Scoring
Minh Hoang Nguyen, Vu Hoang Pham, Xuan Thanh Huynh +5
Large language models (LLMs) have recently reshaped Automated Essay Scoring (AES), yet prior studies typically examine individual techniques in isolation, limiting understanding of…
URAG: A Benchmark for Uncertainty Quantification in Retrieval-Augmented Large Language Models
Vinh Nguyen, Cuong Dang, Jiahao Zhang +6
Retrieval-Augmented Generation (RAG) has emerged as a widely adopted approach for enhancing LLMs in scenarios that demand extensive factual knowledge. However, current RAG evaluati…
Few-Shot VLM-Based G-Code and HMI Verification in CNC Machining
Yasaman Hashem Pour, Nazanin Mahjourian, Vinh Nguyen
Manual generation of G-code is important for learning the operation of CNC machines. Prior work in G-code verification uses Large-Language Models (LLMs), which primarily examine er…
Sanitizing Manufacturing Dataset Labels Using Vision-Language Models
Nazanin Mahjourian, Vinh Nguyen
The success of machine learning models in industrial applications is heavily dependent on the quality of the datasets used to train the models. However, large-scale datasets, speci…
