1. A computing device comprising: at least one processor; and at least one module, operable by the at least one processor to: output, for display at an output device operatively coupled to the computing device, a graphical keyboard; receive an indication of a gesture detected at a location of a presence-sensitive input device, wherein the location of the presence-sensitive input device corresponds to a location of the output device that outputs the graphical keyboard; determine, based on a neural network processing at least one spatial feature of the gesture, at least one character string, wherein the at least one spatial feature indicates at least one physical property of the gesture; and output, for display at the output device, the at least one character string determined based on the neural network processing of the at least one spatial feature of the gesture using the neural network.
