Learning vector quantization (LVQ) is described, with both the LVQ1 and LVQ3 algorithms detailed. This approach involves finding boundaries between classes based on codebook vectors that are created for each class using an iterative neural network. LVQ has an advantage over traditional boundary methods such as support vector machines in the ability to model(More)
BACKGROUND Reablement is a time-limited intervention that aims to support people to regain independence and enable them to resume their daily activities after they return home from an in-patient care setting, or to maintain independence to enable them to remain at home. There is some evidence that reablement can enhance independence and has the potential to(More)
Missing data are a frequent problem in cost-effectiveness analysis (CEA) within a randomised controlled trial. Inappropriate methods to handle missing data can lead to misleading results and ultimately can affect the decision of whether an intervention is good value for money. This article provides practical guidance on how to handle missing data in(More)
BACKGROUND This review scopes the evidence on the effectiveness and cost-effectiveness of interventions to improve suboptimal use of medicines in order to determine the evidence gaps and help inform research priorities. SOURCES OF DATA Systematic searches of the National Health Service (NHS) Economic Evaluation Database, the Cochrane Database of(More)
A new method of polymer classification is described involving dynamic mechanical analysis of polymer properties as temperature is changed. The method is based on the chemometric analysis of the damping factor (tan delta) as a function of temperature. In this study four polymer groups, namely, polypropylene, low density polyethylene, polystyrene and(More)
