Recently least-squares
temporal difference (LSTD) learning
has been developed
for the model-free value function estimation and has
shown good practical performance.
However,
the statistical efficiency
of its estimation has not been well elucidated.
In this study,
we discuss
LSTD-based policy evaluation from
a viewpoint of semiparametric statistical inference.
When the true value function
can be represented by a parametric model,
a consistent estimator of
the value function is
obtained by using a particular estimating function
without knowing the whole data distribution,
such as state transition probability or reward probability.
Especially,
we 1) analyze the asymptotic variance
of the LSTD-based estimator,
2) derive the optimal estimating function
with the minimum asymptotic estimation variance,
and
3) derive the suboptimal estimator to reduce
the computational cost when obtaining the optimal estimating function. |
