Set Transformer: A Framework for Attention-based Permutation-Invariant Neural Networks

Lee, Juho, Lee, Yoonho, Kim, Jungtaek et al.

Understand

Many machine learning tasks such as multiple instance learning, 3D shape recognition, and few-shot image classification are defined on sets of instances.

  • Since solutions to such problems do not depend on the order of elements of the set, models used to address them should be permutation invariant.
  • We present an attention-based neural network module, the Set Transformer, specifically designed to model interactions among elements in the input set.
  • The model consists of an encoder and a decoder, both of which rely on attention mechanisms.
