Non-local Neural Networks

Wang, Xiaolong, Girshick, Ross, Gupta, Abhinav et al.

Understand

Both convolutional and recurrent operations are building blocks that process one local neighborhood at a time.

  • In this paper, we present non-local operations as a generic family of building blocks for capturing long-range dependencies.
  • Inspired by the classical non-local means method in computer vision, our non-local operation computes the response at a position as a weighted sum of the features at all positions.
  • This building block can be plugged into many computer vision architectures.
