The document discusses techniques for analyzing job satisfaction in employees using deep learning algorithms. It proposes applying convolutional neural networks (CNNs) to facial images taken at regular intervals to classify emotions and determine if an employee is happy or stressed. CNNs would be trained to recognize emotions like surprise, fear, disgust, anger, happiness and sadness from facial expressions. The percentage of positive versus negative emotions detected over multiple images could indicate an employee's level of satisfaction. A literature review discusses limitations of existing approaches and supports using CNNs on facial expressions for more accurate analysis of employee mental health and work satisfaction.
