ResNet-18 using PyTorch on Chest X-ray dataset

1. Implementation of ResNet-18 from scratch

2. Using a pre-trained ResNet-18

   a) Using the pre-trained network for classification by retraining only the newly added classifier part

   b) Fine-tuning the pre-trained ResNet-18

3. Modifying the ResNet-18 model architecture

   a) Modifying the original ResNet-18 into ResNet-14 and training from scratch

   b) Modifying the pre-trained ResNet-18 and fine-tuning
