Query: Self-supervised Feature Enhancement: Applying Internal Pretext Task to
  Supervised Learning   Traditional self-supervised learning requires CNNs using external pretext
tasks (i.e., image- or video-based tasks) to encode high-level semantic visual
representations. In this paper, we show that feature transformations within
CNNs can also be regarded as supervisory signals to construct the
self-supervised task, called \emph{internal pretext task}. And such a task can
be applied for the enhancement of supervised learning. Specifically, we first
transform the internal feature maps by discarding different channels, and then
define an additional internal pretext task to identify the discarded channels.
CNNs are trained to predict the joint labels generated by the combination of
self-supervised labels and original labels. By doing so, we let CNNs know which
channels are missing while classifying in the hope to mine richer feature
information. Extensive experiments show that our approach is effective on
various models and datasets. And it's worth noting that we only incur
negligible computational overhead. Furthermore, our approach can also be
compatible with other methods to get better results.
