Deep-Dream: Deep Feature Visualization

1. DeepDream:

   DeepDream is a computer vision program created by Google which uses a ConvNet to find and enhance patterns in images via algorithmic pareidolia, thus creating a dream-like hallucinogenic appearance in the image.

2. The General Idea:

   Rather than synthesizing an image to maximize a specific neuron, instead try to amplify the neuron activations at some layer in the network

3. The Process:

   1. Start with an input image
   2. Run it through a ConvNet up to some layer
   3. Forward: compute activations at chosen layer
   4. Set gradient of chosen layer equal to its activation
   5. Backward: Compute gradient on image
   6. Update Image
   7. Repeat
