In this paper, we address the problem of distributed learning over a large number of distributed sensors or geographically separated data centers, which suffer from sampling biases across nodes. We propose an algorithm called random walk distributed dual averaging (RW-DDA) method that only requires local updates and is fully distributed. Our RW-DDA method is robust to the change in network topo...

We consider the interchange process (IP) on the d-dimensional, discrete hypercube of sidelength n. Specifically, we compare the spectral gap of the IP to the spectral gap of the random walk (RW) on the same graph. We prove that the two spectral gaps are asymptotically equivalent, in the limit n → ∞. This result gives further supporting evidence for a conjecture of Aldous, that the spectral gap ...

The ideas of local search and random walks have been used successfully in several recent satisficing planners. Random Walk-Driven Local Search (RW-LS) is a strong new addition to this family of planning algorithms. The method uses a greedy best-first search driven by a combination of random walks and direct node evaluation. In this way, RW-LS balances between exploration and exploitation. The a...

In previous EARLogs1 we have discussed how to measure and rate the attenuation of hearing protection devices (HPDs) in the laboratory, how these devices affect auditory communications, and perhaps most importantly how HPDs perform in real world (RW) environments. It was found that laboratory attenuation measurements significantly overestimate the RW performance of HPDs, due to the unrealistic, ...

Swine wastewater is characterized by high organic matter content, solids, nitrogen (expressed as total ammonia and protein) and heavy metals. This work determines the methanogenic toxicity effect of free ammonia contained in swine wastewater comparing raw swine wastewater (RW) and the liquid fraction of swine wastewater (TW). The values of IC50 (50% of inhibition) obtained for methanogenic bact...

Dimensionfull quantities are understood as given in lattice units a. {ωL(x)} is the set of all closed lattice paths with length |ωL| = L obtained by RW starting and ending at x. The free RW “measure” (2D) is implemented by the actual procedure, the mass dependence e T is kept explicit. Ul are link variables. For detail see [4]. [email protected] [email protected]...

Reliability and efficiency are important criteria in the design of interconnection networks. Recently, the w-wide diameter dw(G), the (w − 1)-fault diameter Dw(G), and the w-Rabin number rw(G) have been used to measure network reliability and efficiency. In this paper, we study dw(G), Dw(G) and rw(G) using the strong w-Rabin number r∗ w(G) for 1 ≤ w ≤ k(G) and G is a circulant network G(dn; {1,...
