Recursive Gaussian Process Regression Model for Adaptive Quality Monitoring in Batch Processes

Le Zhou, Junghui Chen, Zhihuan Song
2015 Mathematical Problems in Engineering  
When the new batches of data are included, a strategy based on the RGP model is used to choose the proper data for model updating.  ...  In chemical batch processes with slow responses and a long duration, it is time-consuming and expensive to obtain sufficient normal data for statistical analysis.  ...  When a new sample of the process variables x * is collected, the prediction value of quality can be estimated using (3) and the SPE statistic is calculated using (7) .  ...

Responsive and Adaptive Design for Survey Optimization

Asaph Young Chun, Steven G. Heeringa, Barry Schouten
2018 Journal of Official Statistics  
The notion of RAD is not new; nor is it a silver bullet to resolve all the difficulties of complex survey design and challenges.  ...  We call it responsive and adaptive design (RAD), a scientific framework driven by cost-quality tradeoff analysis and optimization that enables the most efficient production of high-quality data.  ...  New developments in survey designs and methods can often take a decade or more to develop and mature with respect to research, publication, and applications in the field.  ...

Threshold estimation: The state of the art

Neil A. Macmillan
2001 Perception & Psychophysics  
The use of computers to simulate adaptive algorithms has proved critical in uncovering the (sometimes unexpected) implications of new testing procedures.  ...  Third, the increasing power of computers enables a kind of stimulus control and data analysis (including the statistical methods just mentioned) that were not available to earlier investigators.  ...  Perhaps as a consequence, articles using adaptive and other psychometric-function methods often employ methods that are not state-of-the-art.  ...
