Don't follow the leader, leader, leader

Follow the leader.

T wo events—the NSW election in May and the recent bitterly divisive leader­ ship struggle between Bob Hawke and Paul Keating—have rewritten the script of politics for the near future. Their effects, clearly, have been quite different, but they have one feature in common; they mark the end of an era for left-of-centre politics in Australia. Labor's decade of triumph between 1983 and 1991 has be...

Vision-based follow-the-leader

We consider the problem of having a group of nonholonomic mobile robots equipped with omnidirectional cameras maintain a desired leader-follower formation. Our approach is to translate the formation control problem from the configuration space into a separate visual servoing task for each follower. We derive the equations of motion of the leader in the image plane of the follower and propose tw...

Optimum Follow the Leader Algorithm

Consider the following setting for an on-line algorithm (introduced in [FS97]) that learns from a set of experts: In trial t the algorithm chooses an expert with probability pi. At the end of the trial a loss vector 1 L ∈ [0, R] for the n experts is received and an expected loss of ∑ i p t iL t i is incurred. A simple algorithm for this setting is the Hedge algorithm which uses the probabilitie...

Follow the leader for online optimization

Follow the Moving Leader in Deep Learning

Deep networks are highly nonlinear and difficult to optimize. During training, the parameter iterate may move from one local basin to another, or the data distribution may even change. Inspired by the close connection between stochastic optimization and online learning, we propose a variant of the follow the regularized leader (FTRL) algorithm called follow the moving leader (FTML). Unlike the ...
