Multi-Graph Transformer for Free-Hand Sketch Recognition

Xu, Peng, Joshi, Chaitanya K., Bresson, Xavier

Understand

Learning meaningful representations of free-hand sketches remains a challenging task given the signal sparsity and the high-level abstraction of sketches.

  • Existing techniques have focused on exploiting either the static nature of sketches with Convolutional Neural Networks (CNNs) or the temporal sequential property with Recurrent Neural Networks (RNNs).
  • In this work, we propose a new representation of sketches as multiple sparsely connected graphs.
  • We design a novel Graph Neural Network (GNN), the Multi-Graph Transformer (MGT), for learning representations of sketches from multiple graphs which simultaneously capture global and local geometric stroke structures, as well as temporal information.
