An adaptive sampling scheme guided by BART—with an application to predict processor performance

The evaluation of new processor designs is an important issue in electrical and computer engineering. Architects use simulations to evaluate designs and to understand trade‐offs and interactions among design parameters. However, due to the lengthy simulation time and limited resources, it is often practically impossible to simulate a full factorial design space. Effective sampling methods and predictive models are required. In this paper, the authors propose an automated performance predictive approach which employs an adaptive sampling scheme that interactively works with the predictive model to select samples for simulation. These samples are then used to build Bayesian additive regression trees, which in turn are used to predict the whole design space. Both real data analysis and simulation studies show that the method is effective in that, though sampling at very few design points, it generates highly accurate predictions on the unsampled points. Furthermore, the proposed model provides quantitative interpretation tools with which investigators can efficiently tune design parameters in order to improve processor performance.

Staff and youth views on autonomy and emancipation from residential care: A participatory research study

The use of participatory approaches in designing services is still relatively uncommon. In this study, we helped design a service to support the transition of youth from residential care to independent living by exploring the perspectives of staff and of youth regarding: (a) the concept and development of autonomy; and (b) key factors in developing this type of service. We gathered the data through 10 interviews with staff (n = 10) and 4 focus groups with youth (n = 21), and subjected the data to a thematic content analysis. Staff defined autonomy as self-regulation and self-care, and identified three paths to foster autonomy – a sense of normality, meaningful relationships, and planning for emancipation. The staff and youth identified the following important aspects in designing the service: achieving normality (e.g. limited number of residents), promoting youth capacity (e.g. skill-building activities), providing social support (e.g. trust and respect between residents), and assuring guidance and boundaries (e.g. supervision of youth).

Maximum entropy sampling and optimal Bayesian experimental design

When Shannon entropy is used as a criterion in the optimal design of experiments, advantage can be taken of the classical identity representing the joint entropy of parameters and observations as the sum of the marginal entropy of the observations and the preposterior conditional entropy of the parameters. Following previous work in which this idea was used in spatial sampling, the method is applied to standard parameterized Bayesian optimal experimental design. Under suitable conditions, which include non-linear as well as linear regression models, it is shown in a few steps that maximizing the marginal entropy of the sample is equivalent to minimizing the preposterior entropy, the usual Bayesian criterion, thus avoiding the use of conditional distributions. It is shown using this marginal formulation that under normality assumptions every standard model which has a two-point prior distribution on the parameters gives an optimal design supported on a single point. Other results include a new asymptotic formula which applies as the error variance is large and bounds on support size.
