Query: Data Summarization via Bilevel Optimization   The increasing availability of massive data sets poses a series of challenges
for machine learning. Prominent among these is the need to learn models under
hardware or human resource constraints. In such resource-constrained settings,
a simple yet powerful approach is to operate on small subsets of the data.
Coresets are weighted subsets of the data that provide approximation guarantees
for the optimization objective. However, existing coreset constructions are
highly model-specific and are limited to simple models such as linear
regression, logistic regression, and $k$-means. In this work, we propose a
generic coreset construction framework that formulates the coreset selection as
a cardinality-constrained bilevel optimization problem. In contrast to existing
approaches, our framework does not require model-specific adaptations and
applies to any twice differentiable model, including neural networks. We show
the effectiveness of our framework for a wide range of models in various
settings, including training non-convex models online and batch active
learning.
