基于共轭平滑的正则化扩散自适应

Regularized Diffusion Adaptation via Conjugate Smoothing

Stefan Vlaski, Lieven Vandenberghe, Ali H. Sayed

摘要:

这项工作的目的是开发和研究一个分布式的帕累托优化策略的总成本包括正规化的风险。每个风险被建模为具有未知概率分布的损失函数的期望,而正则化器被假设为确定性的,但不要求是可微的,甚至是连续的。个体的,正规化的,费用函数分布在一个强连接的网络代理和帕累托最优解寻求呼吁多代理扩散策略。为此,正则化平滑的无穷卷积的手段,它表明,帕累托解决方案的近似,光滑的问题可以任意接近的解决方案的原始,非光滑的问题。性能界限的条件下,比以前在文献中假设的弱,因此适用于更广泛的适应和学习问题。

英文摘要:

The purpose of this work is to develop and study a distributed strategy for Pareto optimization of an aggregate cost consisting of regularized risks. Each risk is modeled as the expectation of some loss function with unknown probability distribution while the regularizers are assumed deterministic, but are not required to be differentiable or even continuous. The individual, regularized, cost functions are distributed across a strongly-connected network of agents and the Pareto optimal solution is sought by appealing to a multi-agent diffusion strategy. To this end, the regularizers are smoothed by means of infimal convolution and it is shown that the Pareto solution of the approximate, smooth problem can be made arbitrarily close to the solution of the original, non-smooth problem. Performance bounds are established under conditions that are weaker than assumed before in the literature, and hence applicable to a broader class of adaptation and learning problems.
