Norm matters: efficient and accurate normalization schemes in deep networks

Hoffer, Elad, Banner, Ron, Golan, Itay et al.

Understand

Over the past few years, Batch-Normalization has been commonly used in deep networks, allowing faster training and high performance for a wide variety of applications.

  • However, the reasons behind its merits remained unanswered, with several shortcomings that hindered its use for certain tasks.
  • In this work, we present a novel view on the purpose and function of normalization methods and weight-decay, as tools to decouple weights' norm from the underlying optimized objective.
  • This property highlights the connection between practices such as normalization, weight decay and learning-rate adjustments.
