The Future: Large datasets of 100 TB will be processed to One needs to train a deep neural network from a large (>>1TB) corpus of data (typically imagery, video, audio, or text). exploit neural networks. Training a self-driving car could take 100 million images at megapixel resolution. Deep learning shares many characteristics with the broader Such training procedures require customization of the neural architecture, learning criteria, and dataset preprocessing. field of machine learning. It takes high computational throughput and high productivity in research exploration. 7 P...
