Designing an FTRL-type algorithm for linear bandits is an important question that has been open for a long time. In this paper, we prove that the FTRL-type algorithm with a negative entropy regularizer can achieve the best-of-three-world results for the linear bandit problem with the tacit ...
It does not appear possible to express this in closed form, but we can find a recursive algorithm for computing the value numerically. It is obvious that V is a symmetric function of its arguments, so we will make the convention in what follows that the arguments of V have been arranged ...
We present an algorithm protected from unrestrictedly large one-step losses. This algorithm has the optimal performance in the case when the scaled fluctuations of one-step losses of experts of the pool tend to zero. 展开 会议名称: Algorithmic Learning Theory, International Conference, Alt, Porto...
This paper investigates the control and localization of a heterogeneous (e.g., different sensing, mechanical, computational capabilities) group of mobile robots. The group considered here has several inexpensive sensor-limited and computationally limited robots, which follow a leader robot in a desired...
of combinatorial optimization problems that admit an FPTAS (fully polynomial time approximation scheme), in which T is the number of rounds of the learning process. In addition to the theoretical analysis, we also conduct a series of experiments to demonstrate the perfor...
The waypoints are then refined using a Follow Shape Rapidly-exploring Random Tree algorithm (FSRRT) for cases that the initial configurations of the CTR cannot completely satisfy the FTL deployment. Simulations and experiments are carried out on a human brain model to validate the proposed methods....
