Grad-CAM: Gradient-weighted Class Activation Mapping
Grad-CAM uses the class-specific gradient information flowing into the final convolutional layer of a CNN to produce a coarse localization map of the important regions in the image. It is a novel technique for making CNN more 'transparent' by producing visual explanations i.e visualizations showing what evidence in the image supports a prediction. You can play with Grad-CAM demonstrations at the following links:

Installing / Getting started
We use RabbitMQ to queue the submitted jobs. Also, we use Redis as backend for realtime communication using websockets.
All the instructions for setting Grad-CAM from scratch can be found here
Note: For best results, its recommended to run the Grad-CAM demo on GPU enabled machines.
