Abstract
Trajectories are generated in response to an input label by using a reverse time delay neural network. The reverse time delay neural network comprises an input layer, a plurality of hidden layers, and an output layer, all arranged in succession so that the number of frames per layer increases as the network is traversed from the input layer to the output layer. Additionally, the number of features decreases as the network is traversed from the input layer to the output layer. Features of the trajectory are created from the input label so that a time series of frames can be output by the network. Frames generally relate to particular epochs of time or time units and a frame includes a plurality of features. Interconnection between layers is accomplished using differential neuron units. In the differential neuron unit, standard neuron weighting, summing, and nonlinear squashing functions are performed on the inputs thereto. Moreover, the output of the differential neuron unit includes a contribution from the value of the corresponding feature in the previous frame in the same layer as the differential neuron unit output.
