WittyTourist Model - How it was Trained 🏋️

The backbone architecture of this convolutional neural net (CNN) is ResNet-50. The model was initially trained on ImageNet and using transfer learning, the weights were re-trained and fine-tuned to fit the landmark classes in this app. This is a multi-class image classification algorithm.
