Place recognition is a challenging but crucial task in robotics. Current
description-based methods may be limited by representation capabilities, while
pairwise similarity-based methods require exhaustive searches, which is
time-consuming. ...
n-Step Temporal Difference Learning with Optimal n

We consider the problem of finding the optimal value of n in the n-step
temporal difference (TD) learning algorithm. Our objective function for the
optimization problem is the average root mean squared error (RMSE). We find the
optimal n by...

We show that extremal Kerr black holes are sensitive probes of new physics.
Stringy or quantum corrections to general relativity are expected to generate
higher-curvature terms in the gravitational action. We show that in the
presence of th...
