Online Open Neuroimaging Mass Meta-Analysis with a Wiki [chapter]

Finn Årup Nielsen, Matthew J. Kempton, Steven C. R. Williams
2015 Lecture Notes in Computer Science  
We describe a system for meta-analysis where a wiki stores numerical data in a simple comma-separated values format and a web service performs the numerical statistical computation.  ...  We initially apply the system on multiple meta-analyses of structural neuroimaging data results.  ...  we present a simple system that allows for mass meta-analysis of numerical data presented as comma-separated values (CSV) in a standard MediaWiki-based wiki, -the Brede Wiki:  ...

Does Feature Selection Improve Classification? A Large Scale Experiment in OpenML [chapter]

Martijn J. Post, Peter van der Putten, Jan N. van Rijn
2016 Lecture Notes in Computer Science  
We conduct a large scale experiment and present results on what algorithms and data sets benefit from this technique. Using meta-learning we can find out for which combinations this is the case.  ...  To complement a large set of meta-features, we introduce the Feature Selection Landmarkers, which prove useful for this task. All our experimental results are made publicly available on OpenML.  ...  Typical meta-features are often categorized as either simple, statistical, information theoretic or landmarkers.  ...

Comparisons of the methods were con- ducted for real data from a 62-item test of reading ability and for computer- generated data for multiple unidimensional and multidimensional cases.  ...  A number of problems with these data suggest that they contain substantial measurement error, which biases conven- tional statistical estimators toward a finding of little or no effect of prices on behavior  ...

Versatile and Efficient Meta-Learning Architecture: Knowledge Representation and Management in Computational Intelligence

Krzysztof Grabczewski, Norbert Jankowski
2007 2007 IEEE Symposium on Computational Intelligence and Data Mining  
This article presents requirements and their motivations for an advanced data mining system, efficient not only in model construction for given data, but also in meta-learning.  ...  There are many data mining systems derived from machine learning, neural network, statistics and other fields. Most of them are dedicated to some particular algorithms or applications.  ...  A general data analysis framework must provide some standard methods for statistical significance testing, and reveal open infrastructure for further extensions.  ...

A mode-based meta-model for the frequency response functions of uncertain structural systems

L. Pichler, H.J. Pradlwarter, G.I. Schuëller
2009 Computers & structures  
The meta-model is supposed to provide a computationally fast solution for the eigenvalue problem, which needs to be solved for each set of random structural input parameters.  ...  In this work a meta-model is presented to approximate the eigenfrequencies and mode shapes to describe the FRFs.  ...  Mass-spring-structure -truss The meta-model for the modal quantities is used to investigate the FRF statistics for the simple mass-spring structure shown in Fig. 4 .  ...

Meta-stable Memory in an Artificial Immune Network [chapter]

Mark Neal
2003 Lecture Notes in Computer Science  
The potential of the algorithm as a tool for multivariate data analysis is also explored.  ...  The algorithm demonstrates the ability of these types of network to produce meta-stable structures representing populated regions of the antigen space.  ...  A selection of these experiments are presented here using a simple graph-layout algorithm to present results, and principal component plots (PCA) to highlight equivalent structure within data sets.  ...
