The goal of the two-sample test (a.k.a. the homogeneity test)
is, given two sets of samples, to judge whether
the probability distributions behind the samples are the same or not.
In this paper, we propose a novel non-parametric method of
two-sample test based on a least-squares density ratio estimator.
Through various experiments, we show that the proposed method
overall produces smaller type-II error
(i.e., the rate of judging the two distributions to be the same
when they are actually different)
than a state-of-the-art method,
with slightly larger type-I error
(i.e., the rate of judging the two distributions to be different
when they are actually the same). |
