From CNN to ViT: Improving Facial Emotion Recognition

馃 Motivation My initial attempt at facial expression recognition, completed during my university studies, involved a convolutional neural network (CNN). Despite limited resources鈥攁 modest GTX 1050 GPU and sparse datasets鈥擨 managed to achieve an accuracy between 65-75%. Although promising, it wasn鈥檛 sufficient for real-world applications, particularly for something as sensitive as mental health diagnostics. Fast forward to today: armed with greater experience, advanced hardware (RTX 3060), and modern ML frameworks, I revisited this challenge using Vision Transformers (ViT). The goal was clear: surpass 80% accuracy and deepen my expertise in state-of-the-art deep learning techniques. ...
