Goal-oriented adaptive sampling under random field modelling of response probability distributions

چکیده

In the study of natural and artificial complex systems, responses that are not completely determined by considered decision variables commonly modelled probabilistically, resulting in response distributions varying across space. We consider cases where spatial variation these does only concern their mean and/or variance but also other features including for instance shape or uni-modality versus multi-modality. Our contributions build upon a non-parametric Bayesian approach to modelling thereby induced fields probability distributions, particular extension logistic Gaussian model. The models deliver probabilistic predictions at candidate points, allowing perform (approximate) posterior simulations density functions, jointly predict multiple moments functionals target as well quantify impact collecting new samples on state knowledge distribution field interest. particular, we introduce adaptive sampling strategies leveraging potential random guide system evaluations goal-oriented way, with view towards parsimoniously addressing calibration related problems from non-linear (stochastic) inversion global optimisation.

Sampling Random Bioinformatics Puzzles using Adaptive Probability Distributions

We present a probabilistic logic program to generate an educational puzzle that introduces the basic principles of next generation sequencing, gene finding and the translation of genes to proteins following the central dogma in biology. In the puzzle, a secret ”protein word” must be found by assembling DNA from fragments (reads), locating a gene in this sequence and translating the gene to a pr...

Selective Sampling Using Random Field Modelling

Most existing inductive learning algorithms assume the availability of a training set of labeled examples. In many domains, however, labeling the examples is a costly process that requires either intensive computation or manual labor. In such cases, it may be beneecial for the learner to be active by intelligent selection of examples for labeling with the goal of reducing the labeling cost. In ...

Probability and Sampling Distributions

When an experiment is conducted, such as tossing coins, rolling a die, sampling for estimating the proportion of defective units, several outcomes or events occur with certain probabilities. These events or outcomes may be regarded as a variable which takes different values and each value is associated with a probability. The values of this variable depends on chance or probability. Such a vari...

Parametric Distributions of Complex Survey Data under Informative Probability Sampling

The sample distribution is defined as the distribution of the sample measurements given the selected sample. Under informative sampling, this distribution is different from the corresponding population distribution, although for several examples the two distributions are shown to be in the same family and only differ in some or all the parameters. A general approach of approximating the margina...

Constructing Random Probability Distributions

Abstrac: This article surveys several classes of iterative methods for constructing random probability distributions (or random convex functions, or random home­ omorphisms), and includes illustrative applications in statistics, optimal-control theory, and game theory. Computer simulations of these methods are fast and easy to implement.
