Abstract

While Deep Neural Networks (DNNs) have achieved tremendous success for large vocabulary continuous speech recognition (LVCSR) tasks, training of these networks is slow. One reason is that DNNs are trained with a large number of training parameters (i.e., 10–50 million). Because networks are trained with a large number of output targets to achieve good performance, the majority of these parameters are in the final weight layer. In this paper, we propose a low-rank matrix factorization of the final weight layer. We apply this low-rank technique to DNNs for both acoustic modeling and language modeling. We show on three different LVCSR tasks ranging between 50–400 hrs, that a low-rank factorization reduces the number of parameters of the network by 30–50%. This results in roughly an equivalent reduction in training time, without a significant loss in final recognition accuracy, compared to a full-rank representation.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • INT4 inference of ResNet50 can bring an additional 50-60% speedup on NVIDIA T4 and RTX compared to its INT8 counterpart.

    “[213] further shows that INT4 inference of ResNet50 could bring an additional 50-60% speedup on NVIDIA T4 and RTX, compared to its INT8 counterpart, emphasizing the importance of using lower-bit precision to maximize efficiency.”
  • Memory required to store the weight matrices can be reduced by using a small projection layer and a small layer before the output layer, or by factorizing a large weight into the product of two smaller matrices.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
