# Topic: Parameter space

 Parameter space - Wikipedia, the free encyclopedia In generative art people talk about parameter space as the set of possible parameters for a generative system. In this case the parameter space is the intervall [0,1]. It is the parameter space for the normal distribution. en.wikipedia.org /wiki/Parameter_space   (201 words)

 Controller design with parameter space methods   (Site not responding. Last check: 2007-10-23) Parameter space design methods are suitable for design of robust control systems and therefore of considerable practical importance. At this stage a parameter space method to be applied to systems with dead-times has been developed. In some applications of standard parameter space methods, it is very difficult to find a design procedure for controllers with more than two parameters. www.esr.ruhr-uni-bochum.de /esr/jd/jd_controller.html   (179 words)

 Parameter Space   (Site not responding. Last check: 2007-10-23) The set of all the possible values of the physical constants is what physicists call the "Parameter Space", and on the surface, if all parameter values are regarded as equally likely, only a small fraction of the parameter space seems to include the constants necessary for life. In this graphic, we represent the Parameter Space schematically as a 2-Dimensional plane, even though, in reality, the parameter space has as many values as there are true physical constants, which certainly number more than 2. Smolin's model challenges the traditional notion of a parameter space where all possible values are equally likely and shows how our particular parameter values could become exponentially favored by Cosmological Natural Selection. cfa-www.harvard.edu /~afriedman/AndysWebPage/BSJ/ParameterSpace.html   (238 words)

 Finding Known Shapes in an Image by Pruning Parameter Space This method is inspired by prior object-recognition methods in which parameter spaces are recursively divided and pruned. The cells are volumes of the parameter space and thus represent continuous ranges of locations of geometric primitives in the parameter space. Each cell in the parameter space is tested to determine whether it can contain the parameters of a primitive that satisfies the acceptance criterion. www.nasatech.com /Briefs/Dec00/NPO20941.html   (641 words)

 FiberBundleHDF5: Functions dealing with the parameter space. Description of a parameter within the uppermost parameter space enveloping all Grid objects. Find a parameter in the parameter space, returning NULL if none found. Get an parameter entry from a parameter space by either finding an existing one or creating and inserting a new one. www.photon.at /sw/F5/group__par.html   (83 words)

 Inquire Curve Parameter Space (3D) Use this command to display the parameter space of a curve. Point markers at each point on a curve associate with a knot value are displayed along with the normalized parameter and arc length values at each point. Specify the number of parameter values between knots to display. www.vx.com /help/0205.htm   (119 words)

 Cosmos Experiments 2: Exploring the Parameter Space In the present chapter we will first investigate the extent to which the differences in behaviour between a number of runs are due purely to the stochastic nature of the system (Section 6.1). With this in mind, the results of a collection of further experiments are then described, which were designed to explore the parameter space of the system somewhat. For all of the experiments reported, any non-default parameter settings are listed; most are specified in the relevant sections of this chapter, but the values of the parameter www.tim-taylor.com /papers/thesis/html/node120.html   (166 words)

 The admissible parameter space for exponential smoothing models   (Site not responding. Last check: 2007-10-23) We discuss the admissible parameter space for some state space models, including the models that underly exponential smoothing methods. We find that the usual parameter restrictions (requiring all smoothing parameters to lie between 0 and 1) do not always lead to stable models. Finally we show that the admissible parameter space of a seasonal exponential smoothing model is much larger than that for a basic structural model, leading to better forecasts from the exponential smoothing model when there is a rapidly changing seasonal pattern. www-personal.buseco.monash.edu.au /~hyndman/papers/invert.htm   (182 words)

 Citebase - SUSY Dark Matter: Closing The Parameter Space Authors: Arnowitt, R. Dutta, B. We consider here the constraints in SUGRA models on the SUSY parameter space due to current experimental bounds on the light Higgs mass m that eliminates the "focus point" regions of parameter space. The most favorable signals of SUSY for linear colliders are stau pair production and neutralino pair production, though it will require an 800GeV machine to cover the full parameter space. citebase.eprints.org /cgi-bin/citations?id=oai:arXiv.org:hep-ph/0210339   (336 words)

 Reducing Parameter Space for Word Alignment - Dejean, Gaussier, Goutte, Yamada (ResearchIndex)   (Site not responding. Last check: 2007-10-23) Abstract: This paper presents the experimental results of our attemps to reduce the size of the parameter space in word alignment algorithm. We use IBM Model 4 as a baseline. In order to reduce the parameter space, we pre-processed the training corpus using a word lemmatizer and a bilingual term extraction algorithm. citeseer.ist.psu.edu /646811.html   (317 words)

 Parameter-space Searches in Forward Fitting   (Site not responding. Last check: 2007-10-23) Tests of 1- and 2-dimensional searches through parameter space for various tilted elliptical Only the subcollimators with angular resolutions from ~ 2 to ~5 times the widths give a minimum near the correct value of tilt (45 degrees). This again indicates that the parameter search must "know" about under- and over - resolution. hesperia.gsfc.nasa.gov /~schmahl/fwd_fitting/search_tests.html   (242 words)

 surface parameter space orientation I am having a hard time figuring out if orientation of surface is always same (or opposite) as orientation of associated (u,v) parameter space.
