*Abstract*:
This contribution develops a theoretical framework
that takes into account the effect of approximate
optimization on learning algorithms.
The analysis shows distinct tradeoffs for the
case of small-scale and large-scale learning problems.
Small-scale learning problems are subject to the
usual approximation–estimation tradeoff.
Large-scale learning problems are subject to
a qualitatively different tradeoff involving the computational
complexity of the underlying optimization
algorithms in non-trivial ways.

This paper establishes a formal distinction between small-scale and large-scale learning systems. The generalization performance of small-scale systems is entirely defined by the statistical properties of their estimation procedure. The generalization performance of large-scale systems also depends on the chosen optimization algorithm. In particular, stochastic gradient algorithms display very good generalization performances despite being very poor optimization algorithms. Here is a very clear experimental validation.
