Query: Learning Class Regularized Features for Action Recognition   Training Deep Convolutional Neural Networks (CNNs) is based on the notion of
using multiple kernels and non-linearities in their subsequent activations to
extract useful features. The kernels are used as general feature extractors
without specific correspondence to the target class. As a result, the extracted
features do not correspond to specific classes. Subtle differences between
similar classes are modeled in the same way as large differences between
dissimilar classes. To overcome the class-agnostic use of kernels in CNNs, we
introduce a novel method named Class Regularization that performs class-based
regularization of layer activations. We demonstrate that this not only improves
feature search during training, but also allows an explicit assignment of
features per class during each stage of the feature extraction process. We show
that using Class Regularization blocks in state-of-the-art CNN architectures
for action recognition leads to systematic improvement gains of 1.8%, 1.2% and
1.4% on the Kinetics, UCF-101 and HMDB-51 datasets, respectively.
