Cost Models DO Matter: Providing Cost Information for Diverse Data Sources in a Federated System
An important issue for federated systems of diverse data sources is optimizing cross-source queries, without building knowledge of individual sources into the optimizer. This pape...

Ordinal Hyperplanes Ranker with Cost Sensitivities for Age Estimation
In this paper, we propose an ordinal hyperplane ranking algorithm called OHRank, which estimates human ages via facial images. The design of the algorithm is based on the relative...

Adaptive control using retrospective cost optimization with RLS-based estimation for concurrent Markov-parameter updating
We present a discrete-time adaptive control law that is effective for systems that are MIMO and either minimum phase or nonminimum phase. The adaptive control algorithm provides gu...
