1 They are the main type of gallstones in the UK and the USA.  Pigment gallstones - these form when the bile has too much bilirubin. They are more common among patients who have liver disease, infected bile tubes or blood disorders, such as sickle-cell anemia.
DeepDream is a computer vision program created by Google which uses a convolutional neural network to find and enhance patterns in images via algorithmic pareidolia, thus creating a dream-like hallucinogenic appearance in the deliberately over-processed images.
Deep learning refers to both deep neural networks and other branches of machine learning like deep reinforcement learning. In the press, it usually means deep neural nets. Neural networks are a set of algorithms, modeled loosely after the human brain, that are designed to recognize patterns.
