Global dispersal reduces local diversity.

Metapopulation models and stepping-stone models in genetics are based on very different underlying dispersal structures, yet it can be difficult to distinguish the behaviour of the two kinds of models. We demonstrate a striking qualitative difference in the equilibrium behaviour possible with these two kinds of dispersal. If, in a local patch, there are multiple stable equilibria (and consequen...

Local and global convergence of on-line learning.

We study the performance of an on-line algorithm for learning di-chotomies, with a dynamical error-dependent learning rate. The asymp-totic scaling form of the solution to the associated Markov equations is derived, assuming certain smoothness conditions. We show that the system converges to the optimal solution and the generalization error vanishes inversely with the number of examples. The sy...

Fasting and diabetes from a local and global perspective- commentary

  Fasting is a common practice among people with diabetes (PWD). As healthcare providers we are in a position to assist those who choose to fast to manage their diabetes effectively. Diabetes self-management education for PWD is needed both prior and during the time of fasting to best metabolic control.

Stochastic Convex Optimization: Faster Local Growth Implies Faster Global Convergence

In this paper, a new theory is developed for firstorder stochastic convex optimization, showing that the global convergence rate is sufficiently quantified by a local growth rate of the objective function in a neighborhood of the optimal solutions. In particular, if the objective function F (w) in the -sublevel set grows as fast as ‖w − w∗‖ 2 , where w∗ represents the closest optimal solution t...
