Query: Learning to Amend Facial Expression Representation via De-albino and
  Affinity   Facial Expression Recognition (FER) is a classification task that points to
face variants. Hence, there are certain affinity features between facial
expressions, receiving little attention in the FER literature. Convolution
padding, despite helping capture the edge information, causes erosion of the
feature map simultaneously. After multi-layer filling convolution, the output
feature map named albino feature definitely weakens the representation of the
expression. To tackle these challenges, we propose a novel architecture named
Amending Representation Module (ARM). ARM is a substitute for the pooling
layer. Theoretically, it can be embedded in the back end of any network to deal
with the Padding Erosion. ARM efficiently enhances facial expression
representation from two different directions: 1) reducing the weight of eroded
features to offset the side effect of padding, and 2) decomposing facial
features to simplify representation learning. Experiments on public benchmarks
prove that our ARM boosts the performance of FER remarkably. The validation
accuracies are respectively 90.42% on RAF-DB, 65.2% on Affect-Net, and 58.71%
on SFEW, exceeding current state-of-the-art methods. Our implementation and
trained models are available at
