Priced Learning
In iterative learning the memory of the learner can only be updated when the hypothesis changes; this results in only finitely many updates of memory during the overall learning history. Priced learning relaxes this constraint on the update of memory by imposing some price on the updates of the memory – depending on the current datum – and requiring that the overall sum of the costs incurred ha...
متن کاملPhospholipogenic Pharmaceuticals Are Associated with a Higher Incidence of Histological Findings than Nonphospholipogenic Pharmaceuticals in Preclinical Toxicology Studies
While phospholipidosis is thought to be an adaptive response to chemical challenge, many phospholipogenic compounds are known to display adverse effects in preclinical species and humans. To investigate the link between phospholipogenic administration and incidence of preclinical histological signals, an internal AstraZeneca in vivo toxicology report database was searched to identify phospholip...
متن کاملHospital Acquisition of Physician Groups: On the Road to Value-Based or Higher-Priced Care?
An important goal of the Affordable Care Act is to transform the US health care system from one characterized by high costs, poor quality, and fragmented care to one focused on comprehensive, coordinated, and efficient care. The Centers for Medicare & Medicaid Services (CMS) is working to meet this goal primarily through efforts to strengthen primary care and to introduce innovative new payment...
متن کاملAnalysis of spatial autocorrelation in higher-priced mortgages: Evidence from Philadelphia and Chicago
An accurate and reliable model is critical for analyzing racial/ethnic and socioeconomic inequality in the spatial distribution of higher-priced/subprime mortgages. Employing a spatial error model, this research analyzes spatial autocorrelation in higher-priced mortgages in the Philadelphia and Chicago MSAs. The empirical results show that higher-priced mortgages occur disproportionately on tra...
متن کاملPriced Timed Petri Nets
We consider priced timed Petri nets, i.e., unbounded Petri nets where each token carries a real-valued clock. Transition arcs are labeled with time intervals, which specify constraints on the ages of tokens. Furthermore, our cost model assigns token storage costs per time unit to places, and firing costs to transitions. This general model strictly subsumes both priced timed automata and unbound...
