CNN modelling on Chest-Xray data set

The CNN modelling exercise here are for classifying "Normal" and "Pneumonia" from chest-Xray data set. The image data itself is not included because of size - but the structured in folder -subfolder, the main folder have subfolders train, test, validation. In each subfolder, there are two folders called "Normal" and "Pneumonia" containing relevant images. The matlab script includes two files (i) using CNN model from scratch (ii) using pretrained network architecture
