Grad-CAM implementation in Keras

Part of the code borrowed from https://github.com/jacobgil/keras-grad-cam

Able to run in keras 2.0

Part 1: (transfer learning folder) To train a transfer learning model: run train_inception_resnetv2.py

Or use two stage training: run train_inception_resnetv2_two_stage_1.py then run run train_inception_resnetv2_two_stage_2.py

Part 2: (grad-cam_for_trained_model folder) To get the grad cam results: run grad-cam-inception_resnetv2-batch-requested_v2.py (the other two versions also work)
