Optimizing Alternatives in Precedence Networks
2010Precedence networks can naturally describe workflows. Frequently, it is important to model alternative routes in the workflow and to select the best alternative while respecting various constraints. In this paper we suggest how to extend an existing model of Nested Temporal Networks with Alternatives by adding preferences on alternatives.

An alternating optimization approach for phase retrieval
Interspeech 2015, 2015In this paper, we address the problem of phase retrieval to recover a signal from the magnitude of its Fourier transform. In many applications of phase retrieval, the signals encountered are naturally sparse. In this work, we consider the case where the signal is sparse under the assumption that few components are nonzero. We exploit further the sparse

Optimizing for Engagement Can Be Harmful. There Are Alternatives
IEEE Intelligent Systems, 2020Reports on the topic of personalization systems. These systems, including content filtering and recommender engines, have become the cornerstone of social media and digital business strategy. Back in 2016, Netflix estimated its recommendation engine brought $1 billion in value to the company. On Amazon, 35% of purchases come via recommendations (https:/

IEEE Transactions on Vehicular Technology, 2006
One of the primary design requirements of automotive generation systems is maximizing power density subject to the constraint of minimizing the overall system cost. However, with the progress made in the reduction of automotive drive train noise, the torque ripple of the generator has been found to be a dominant noise source under idle conditions at ...

Alternative Query Optimization for Workload Management
2012Systems with heavy workloads run many queries concurrently. Modern database workloads—as those incurred by business intelligence applications—involve ad-hoc, highly complex, expensive queries. While query plans are optimized individually, the workload overall is not. Plans running together incur resource contention, resulting in sub-optimal performance.

Optimality Conditions in Terms of Alternance: Two Approaches
Journal of Optimization Theory and Applications, 2014The article of V.F. Demyanov and V.N. Malozemov is a valuable contribution to the area of nondifferentiable or nonsmooth calculus and, especially, optimization. This investigation takes place in a wide set-theoretical and analytic setting, and very elegantly generalizes and, as special cases, includes, basic and famous numerical approaches of ...
