TITLE: GIO: Gradient Information Optimization for Training Dataset Selection 

ABSTRACT: It is often advantageous to train models on a subset of the available train
examples, because the examples are of variable quality or because one would
like to train with fewer examples, without sacrificing performance. We present
Gradient Information Optimization (GIO), a scalable, task-agnostic approach to
this data selection problem that requires only a small set of (unlabeled)
examples representing a target distribution. GIO begins from a natural,
information-theoretic objective that is intractable in practice. Our
contribution is in showing that it can be made highly scalable through a simple
relaxation of the objective and a highly efficient implementation. In
experiments with machine translation, spelling correction, and image
recognition, we show that GIO delivers outstanding results with very small
train sets. These findings are robust to different representation models and
hyperparameters for GIO itself. GIO is task- and domain-agnostic and can be
applied out-of-the-box to new datasets and domains.
