Age and Gender Prediction using Deep CNNs and Transfer Learning
In this paper, we focus on this challenging problem. Specifically, this paper focuses on the problem of age estimation, age classification, and gender classification from still facial images of an individual. We train different models for each problem, and we also draw comparisons between building a custom CNN (Convolutional Neural Network) architecture and using various CNN architectures as feature extractors, namely VGG16 pre-trained on VGGFace, ResNet50, and SE-ResNet50 pre-trained on the VGGFace2 dataset, and training over those extracted features. We also provide baseline performance for various machine learning algorithms on feature extraction, which yielded the best results. It was observed that even simple linear regression trained on these extracted features outperformed training a CNN (ResNet50) and a ResNeXt50 from scratch for age estimation.
