Projects

Mental Workload Estimation
Python Keras Dash
Mental Workload Estimation
Mental workload (MWL) refers to brain activities, which are the number of resources in the human brain.
Emotion Analysis
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.
Stress Estimation
Python Pytorch
Stress Estimation
Sentiment analysis is an aspect momentous for application in the future. Especially, emotional stress estimation helps improve our life.
