I am personally skeptical of all the Lean Startup methodology. I think the really great companies did something that was sort of a quantum improvement that really differentiated them.
(via Stanford University CS231n: Convolutional Neural Networks for Visual Recognition)
"We present a model that generates free-form natural language descriptions of image regions. Our model leverages datasets of images and their sentence descriptions to learn about the inter-modal correspondences between text and visual data."
This is happening.
