AB - Recurrent Neural Networks, with the prominence of LongShort-Term Memory (LSTM) networks, have demonstrated state-of-the-art accuracy in several emerging Artificial Intelligence tasks. Neverthe-less, the highest performing LSTM models are becoming increasinglydemanding in terms of computational and memory load. At the sametime, emerging latency-sensitive applications including mobile robots andautonomous vehicles often operate under stringent computation timeconstraints. In this paper, we address the challenge of deploying com-putationally demanding LSTMs at a constrained time budget by intro-ducing an approximate computing scheme that combines iterative low-rank compression and pruning, along with a novel FPGA-based LSTMarchitecture. Combined in an end-to-end framework, the approximationmethod parameters are optimised and the architecture is configuredto address the problem of high-performance LSTM execution in time-constrained applications. Quantitative evaluation on a real-life imagecaptioning application indicates that the proposed system required up to6.5×less time to achieve the same application-level accuracy comparedto a baseline method, while achieving an average of 25×higher accuracyunder the same computation time constraints.
