*Title*:           Balanced Filtering via Disclosure-Controlled Proxies


*Abstract:*      We study the problem of collecting a sample of data
balanced with respect to sensitive groups when group membership is
unavailable or prohibited from use at deployment time. Specifically, our
deployment-time collection mechanism does not reveal significantly more
about the group membership of any individual sample than can be ascertained
from base rates alone. To do this, we adopt a fairness pipeline
perspective, in which a learner can use a small set of labeled data to
train a proxy function that can later be used for this filtering task. We
then associate the range of the proxy function with sampling probabilities;
given a new data sample, we classify it using our proxy function and then
select it for our sample with probability proportional to the sampling
probability corresponding to its proxy classification.  Importantly, we
require that the proxy classification does not reveal significant
information about the sensitive group membership of any individual sample
(i.e., the level of disclosure should be controlled). We show that under
modest algorithmic assumptions, we find such a proxy in a sample- and
oracle-efficient manner. Finally, we experimentally evaluate our algorithm
and analyze its generalization properties.

*Research at TTIC Seminar Series*



TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended for students seeking
research topics and advisors and for the general TTIC and University of
Chicago communities interested in hearing what their colleagues are up to.
