IMPORTANT

Absolutely, under NO circumstance, should one ever screen patients using computer vision software trained with this code (or any home made software for that matter).

Data

The dataset can be downloaded from here. This is a binary classification problem. I split the data as shown-

dataset train

   b1.jpg
   b2.jpg
   //
  malignant
   m1.jpg
   m2.jpg
   //  validation
