摘要:Motivated by a medical decision making problem, this paper focuses on an impulse control problem for a class of piecewise deterministic semi-Markov processes. The process evolves deterministically between jumps and the inter-jump times have a general distribution. %that may depend on both coordi...
Moreover, relative parameter bias (defined as = [alignment parameter – average of the parameter estimates across replications] / alignment parameter * 100) for the means and the proportion of replications for which the 95% confidence interval contains the mean were calculated. The alignment ...
Old memories can be preserved after hippocampal damage despite amnesia for recent ones8, suggesting that memories initially encoded in the hippocampus end up being stored in neocortical areas, an idea known as ‘systems consolidation’9. The standard model of systems consolidation involves transfer of ...
I check the performance of the algorithm by running the VFSA code 100 times on each catalog. Specifically, for each parameter and each catalog, I measure the systematic and the random errors by three quantities: the accuracy, i.e., the closeness of the estimations to the true values, the ...
On the sensitivity of the Measurements of angular correlations in nuclear beta decay are important tests of the Standard Model (SM). Among those, the so-calledDcorrelation parameter occupies a particular place because it is odd under time reversal, and because the experimental sensitivity is at ...
We now return to the application that motivated our work, namely the building of a population of models. In the setting of a population of models (POM) a mathematical model is calibrated by a set of points, rather than a single point, in parameter space, all of which are selected to fi...
First, you have the intercept. This is the estimate for the β 0 parameter in your model. It tells you the expected value of the outcome when the other variables in the model are zero. Since the only other variable here is the challenger indicator, you can interpret the intercept as the...
parameter(s) of such a model can potentially be used to compare the intra- or inter-specific variation in egg shapes, and even that between classes. Recently, Narushin et al. [2] proposed a general egg-shape equation that can describe many extant egg shapes of birds, which is referred ...
5a is the tipping point, and the dashed line in Fig. 5b is the asymptote for the variance. With the parameter values completely determined, the confidence levels are calculated: The two-standard error levels around the baseline values of the EWS are shown by purple bands in Fig. 5b, c. ...
the sense that the training targets are observed variables like soil moisture or streamflow, rather than intermediate variables such as parameters estimated by other means. Our framework transforms the typically inverse parameter calibration problem into a big-data DL problem, leveraging the efficiency ...
