Emotion Classification of Children Expressions

TL;DR

This paper develops a specialized facial emotion classification model for children, achieving high accuracy by using advanced neural network techniques and data augmentation to address the lack of child-specific emotion recognition systems.

Contribution

It introduces a novel model incorporating attention mechanisms and data synthesis for improved emotion detection in children, filling a gap in existing adult-focused systems.

Findings

Achieved 89% accuracy in classifying children's emotions.

Utilized data augmentation with Stable Diffusion for diverse training samples.

Enhanced model performance with SE blocks and attention modules.

Abstract

This paper proposes a process for a classification model for the facial expressions. The proposed process would aid in specific categorisation of children's emotions from 2 emotions namely 'Happy' and 'Sad'. Since the existing emotion recognition systems algorithms primarily train on adult faces, the model developed is achieved by using advanced concepts of models with Squeeze-andExcitation blocks, Convolutional Block Attention modules, and robust data augmentation. Stable Diffusion image synthesis was used for expanding and diversifying the data set generating realistic and various training samples. The model designed using Batch Normalisation, Dropout, and SE Attention mechanisms for the classification of children's emotions achieved an accuracy rate of 89\% due to these methods improving the precision of emotion recognition in children. The relative importance of this issue is raised in this study with an emphasis on the call for a more specific model in emotion detection systems for the young generation with specific direction on how the young people can be assisted to manage emotions while online.
