TLDR
These two sessions can be treated as a continuation of another conference which was hosted in October 1998 also at the Zentralarchiv fuer Empirische Sozialforschung, organized by Henry Rouanet and Joerg Blasius.Abstract:
On Thursday, 5 October, and on Friday, 6 October, we had two sessions on &dquo;Geometric Data Analysis&dquo;. The title of the sessions is the English translation of the French &dquo;L’Analyse des Donnees&dquo; which includes different techniques of visualization of data, from principal components analysis to multiple-correspondence analysis. The main idea formulated by the &dquo;father&dquo; of the &dquo;L’Analyse des Donnees&dquo;, Jean-Paul Benzecri, is that the model has to follow the data and not vice versa. Whereas the session from Michael Greenacre on &dquo;Multiple-Correspondence Analysis and its Interpretation&dquo; (Wednesday, 4 October) was mainly focussed on the technique itself, the idea of these two sessions was to give substantive examples using this method. Since correspondence analysis largely found its way into the social sciences via the publications by Pierre Bourdieu, and since many of the below listed contributors are closely connected with him and his work, many of the papers dealt with applications of his theory. In this way, the two sessions can be treated as a continuation of another conference which was hosted in October 1998 also at the Zentralarchiv fuer Empirische Sozialforschung, organized by Henry Rouanet and Joerg Blasius (forread more

Missing point estimation in models described by proper orthogonal decomposition
TL;DR: The effectiveness of the MPE method is demonstrated by applying it to a nonlinear computational fluid dynamic model of an industrial glass furnace and the Galerkin projection can be computed using only 25% of the spatial grid points without compromising the accuracy of the reduced model.

Setting cost in Optimal Matching to uncover contemporaneous socio-temporal patterns
TL;DR: In this article, it is argued that the balance between indel (insertion and deletion) and substitution costs determines what kind of socio-temporal pattern can be brought to light.

Super-Resolution Method for Face Recognition Using Nonlinear Mappings on Coherent Features
Hua Huang,Huiting He +1 more
TL;DR: A super-resolution method that uses nonlinear mappings to infer coherent features that favor higher recognition of the nearest neighbor (NN) classifiers for recognition of single LR face image outperforms the state-of-the-art face recognition algorithms for single LR image in terms of both recognition rate and robustness to facial variations of pose and expression.

TL;DR: It is demonstrated that the modulations of the firing-rates of cortical neurons increased abruptly after the monkeys started operating the BMI, and regression analysis revealed that these enhanced modulations were not correlated with the kinematics of the movement.

Reconstruction with Voronoi centered radial basis functions
TL;DR: This work considers the problem of reconstructing a surface from scattered points sampled on a physical shape by using as centers of basis functions a set of points located on an estimate of the medial axis, instead of the input data points.
