We will build and train a Deep Convolutional Neural Network (CNN) with Residual Blocks to detect the type of scenery in an image. In addition, we will also use a technique known as Gradient-Weighted Class Activation Mapping (Grad-CAM) to visualize the regions of the inputs and help us explain how our CNN models think and make decision.

Introduction

In this project, we will build and train a Deep Convolutional Neural Network (CNN) and Residual Blocks to detect the type of scenery in an image. In addition, we will also use a technique known as Gradient-Weighted Class Activation Mapping (Grad-CAM) to visualize the regions of the inputs and help us explain how our CNN models think and make decision.

Future Work

• Try other approaches to explain CNN outputs such as: Activations Visualization, Vanilla Gradients, Occlusion Sensitivity, CNN Fixations, and Class Activation Mapping (CAM).

• Apply Transfer Learning
