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...
This paper presents a follow-the-leader algorithm for control of the Payload Inspection and Processing System (PIPS) at NASA Kennedy Space Center. PIPS is an automated system, programmed off-line for inspection of Space Shuttle payloads after integration and prior to launch. PIPS features a hyper...
While FOBOS handles the L1 term exactly on any given update, we show that it is effectively using subgradient approximations to the L1 penalty from previous rounds, leading to less sparsity than RDA, which handles the cumulative penalty in closed form. The FTRL-Proximal algorithm, which we ...
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...
