Big data analytics has attracted close attention from both industry and academic because of its great benefits in cost reduction and better decision making. As the fast growth of various global services, there is an increasing need for big data analytics across multiple data centers (DCs) located in different countries or regions. It asks for the support of a cross-DC data processing platform optimized...
This paper presents two strategies to speed up the alternating direction method of multipliers (ADMM) for distributed data. In the first method, inspired by stochastic gradient descent, each machine uses only a subset of its data at the first few iterations, speeding up those iterations. A key result is in proving that despite this approximation, our method enjoys the same convergence rate in terms...
