The rapid growth in the size and scope of datasets in science and technology has
created a need for novel foundational perspectives on data analysis that blend
the statistical and computational sciences. That classical perspectives from these
fields are not adequate to address emerging problems in "Big Data" is apparent
from their sharply divergent nature at an elementary level---in computer
science, the growth of the number of data points is a source of "complexity"
that must be tamed via algorithms or hardware, whereas in statistics, the growth
of the number of data points is a source of "simplicity" in that inferences
are generally stronger and asymptotic results can be invoked. Indeed, if
data are a data analyst's principal resource, why should more data be burdensome
in some sense? Shouldn't it be possible to exploit the increasing inferential
strength of data at scale to keep computational complexity at bay? I present
three research vignettes that pursue this theme, the first involving the
deployment of resampling methods such as the bootstrap on parallel and
distributed computing platforms, the second involving large-scale matrix
completion, and the third introducing a methodology of "algorithmic weakening,"
whereby hierarchies of convex relaxations are used to control statistical risk as
data accrue.
