OP: Just curious, how do you know they don't use deep learning? @opless: Deep learning may be a fad in the press, but there's substance underneath. It's been breaking one accuracy record after another in raw, unstructured media year after year. ImageNet is just one deep convolutional net competing against another. A lot of other ML algorithms have hit a ceiling, and the ceiling is tied to not having enough humans to engineer enough features. DL doesn't have that chokepoint, and it is able to process vast seas of data that other algos have trouble with. Therefore, for many problems, it will continue to win.
