Query: Variational Adversarial Active Learning   Active learning aims to develop label-efficient algorithms by sampling the
most representative queries to be labeled by an oracle. We describe a
pool-based semi-supervised active learning algorithm that implicitly learns
this sampling mechanism in an adversarial manner. Unlike conventional active
learning algorithms, our approach is task agnostic, i.e., it does not depend on
the performance of the task for which we are trying to acquire labeled data.
Our method learns a latent space using a variational autoencoder (VAE) and an
adversarial network trained to discriminate between unlabeled and labeled data.
The mini-max game between the VAE and the adversarial network is played such
that while the VAE tries to trick the adversarial network into predicting that
all data points are from the labeled pool, the adversarial network learns how
to discriminate between dissimilarities in the latent space. We extensively
evaluate our method on various image classification and semantic segmentation
benchmark datasets and establish a new state of the art on
$\text{CIFAR10/100}$, $\text{Caltech-256}$, $\text{ImageNet}$,
$\text{Cityscapes}$, and $\text{BDD100K}$. Our results demonstrate that our
adversarial approach learns an effective low dimensional latent space in
large-scale settings and provides for a computationally efficient sampling
method. Our code is available at https://github.com/sinhasam/vaal.
