Abstract
A computer-implemented method for translating with limited attention a sequence of input tokens into a sequence of output tokens may include (1) encoding by an encoder recurrent neural network (RNN) N input tokens of a sequence of (N+D) input tokens into an attention matrix limited to N input tokens, (2) iteratively updating a previous version of the attention matrix with the context vector generated from each excess input token yielding a final attention matrix at the last excess input token (D), and (3) decoding an output token using a decoder RNN with inputs from at least the weighted context vector and the just previously-determined output token of the decoder. The weighted context vector may be derived from an attention RNN processing the elements of the final attention matrix for each of the decoder output tokens. Various other methods, systems, and computer-readable media are also disclosed.
