How Attractive Are You in the Eyes of Deep Neural Network?

The original paper implemented a bunch of different models, including classic ML models with handcrafted features and 3 deep learning models: AlexNet, ResNet18, and ResNext50. I want to keep my work as simple as possible (I don't want to implement and train the whole resnet network from scratch), I want to fine tune some existing model that will do the job. In keras, there's a module called applications, which is a collection of different pre-trained models. One of them is resnet50. ResNet is a Deep Convolutional network that was developed by Microsoft and won the 2015 ImageNet competition, which is an image classification task.
