About Me
Hong-Hai Nguyen received his B.S. degree from the Department of Mathematics and Computer Science, Ho Chi Minh City University of Science (VNUHCM), Vietnam, in 2018. He joined PRLab in March 2021. He received his M.S. degree from the Department of Artificial Intelligence Convergence at Chonnam National University, South Korea, in 2023.
His research interests include Pattern Recognition, Sentiment Analysis, and Cognitive Load.
Here are a few technologies I've been working with recently:
- Python
- R
- SQL
- LaTex
- C/C++
- MATLAB
Experience
Data preparation: Collect and label data from the data generation step. Clean and check the data set for missing or incomplete before the training step.
Image enhancement: Convert X-ray image from High Dynamic Range (32bit) to Low Dynamic Range (8bit) for display on the device.
Object detection: Using Image Processing and Deep Learning algorithms for detection of elements battery.
Deployment and improvement: Integrate and test model in real-time on the machine in the factory. Ongoing improvement to adapt to new data and conditions
Mental Workload Estimation: Experiment with STEW dataset. We conducted experiments on classification and regression for Mental workload.
Stress Estimation: Experiment with Ulm-TSST dataset, We conducted experiments on Valence-Arousal estimation in Multimodal Emotional Stress Sub-challenge of Multimodal Sentiment Analysis Challenge (MuSe).
Valence-Arousal Estimation: Experiment on the Aff-Wild2 dataset. We achieved 3rd place in Task 1 - Valence-Arousal Estimation in Workshop and Competition on Affective Behavior Analysis in-the-wild.
Research and development of tools based on potential software.
R&D automation scripts and tools inside and outside a 3D application to help the artist can be quickly worked on.
Installation and troubleshooting of software, plugins, and scripts.
Supporting producers and team leaders in training for newbies.
Motorcycle detection: Research histograms of oriented gradients (HOG), local binary patterns (LBP) features and support vector machines (SVM) for detection.

Mental Workload Estimation
Mental workload (MWL) refers to brain activities, which are the number of resources in the human brain.
Python
Pytorch
Emotion Analysis
The 2D Valence and Arousal Space (VA-Space) is the most usual dimensional emotion representation; valence shows how positive or negative an emotional state is, whilst arousal shows how passive or active it is.
Python
Pytorch
Stress Estimation
Sentiment analysis is an aspect momentous for application in the future. Especially, emotional stress estimation helps improve our life.
