The FTRL-Proximal algorithm uses the updateWt+1=argwmin(g1:t.w+1/2∑ts=1σs||w−ws||22+λ1||w||1)Wt+1=argwmin(g1:t.w+1/2∑s=1tσs||w−ws||22+λ1||w||1),σ1:t=1/ηtσ1:t=1/ηt when we takeλ1=0λ1=0, they produce an identical sequence of coefficien...
Follow-the-regularized-leader (FTRL) is another popular algorithm type that can adapt to different environments. This algorithm is of simple design and the regret bounds are shown to be optimal in traditional multi-armed bandit problems compared with the detect-switch type algorithms. Designing an ...
Summary: In this paper the sequential prediction problem with expert advice is considered for the case when the losses of experts suffered at each step can be unbounded. We present some modification of Kalai and Vempala algorithm of following the perturbed leader where weights depend on past losse...
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 propose a variant of the Follow-the-Perturbed-Leader (FPL) algorithm to solve this problem. Unlike the existing FPL approach, our method employs an approximation algorithm as an offline oracle and perturbs the collected data by adding nonnegative random variables. O...
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...
