Least-Commitment Action Selection
The principle of least commitment was embraced early in planning research. Hierarchical task networks (HTNs) reason about high-level tasks without committing to specific low-level steps. Partial-order planning arose from a complementary desire to avoid unnecessary ordering commitments. But most of today’s partial-order planning algorithms commit to a single producing step when supporting an ope...
متن کاملModeling Natural Action Selection
Neurophysiological evidence due to Schall,Newsome and others indicates that decision proc-esses in certain cortical areas (e.g. FEF and LIP)involve the integration of noisy evidence. Withinthis paradigm, we ask which neuronal architecturesand parameter values would allow an animal tomake the fastest and most accurate decisions. Sinceevolutionary pressure promotes suc...
متن کاملDo we expect natural selection to produce rational behaviour ? For : Modelling Natural Action Selection
We expect that natural selection has resulted in behavioural rules that perform well, however animals (including humans) sometimes make bad decisions. Researchers account for these with a variety of explanations; we concentrate on two of them. One is that the outcome is an side-effect; what matters is how a rule performs (in terms of reproductive success). Several rules may perform well in the ...
متن کاملNatural selection in action during speciation.
The role of natural selection in speciation, first described by Darwin, has finally been widely accepted. Yet, the nature and time course of the genetic changes that result in speciation remain mysterious. To date, genetic analyses of speciation have focused almost exclusively on retrospective analyses of reproductive isolation between species or subspecies and on hybrid sterility or inviabilit...
متن کاملModel selection for partial least squares regression
Partial least squares (PLS) regression is a powerful and frequently applied technique in multivariate statistical process control when the process variables are highly correlated. Selection of the number of latent variables to build a representative model is an important issue. A metric frequently used by chemometricians for the determination of the number of latent variables is that of Wold’s ...
