2014 The Scientific World Journal  
Given an initial set of features, it automatically selects the most significant ones and performs a statistical comparison using them.  ...  This paper presents a new approach to perform robot trajectories comparison that could be applied to any kind of trajectories and in both simulated and real environments.  ...  This is the first thing to be done by a statistical analysis of the data.  ...

A statistical approach to adaptive problem solving

Jonathan Gratch, Gerald DeJong
1996 Artificial Intelligence  
We develop a formal characterization of the utility problem and introduce COMPOSER, a statistically rigorous learning approach which avoids the utility problem.  ...  General approaches have proven successful in complex real-world situations only after a tedious cycle of manual experimentation and modification.  ...  Adam Martinsek assisted us on numerous statistical issues. Thanks also to Marsha Brofka, Dan Oblinger, Oren Etzioni, and the anonymous reverers for critical comments on earlier versions of this work.  ...

Testing quantum mechanics: a statistical approach

Mankei Tsang
2013 Quantum Measurements and Quantum Metrology  
As experiments continue to push the quantum-classical boundary using increasingly complex dynamical systems, the interpretation of experimental data becomes more and more challenging: when the observations  ...  tutorial highlights some of the difficulties in such experimental tests of quantum mechanics, using optomechanics as the central example, and discusses how the issues can be resolved using techniques from statistics  ...  Acknowledgments It is impossible to list all the people who help shape the views expressed here through various forms of interactions, but surely the most important are the ones who have also paid me while  ...

Social Capital and Climate A First Statistical Approach

Marta Felis-Rota
2010 Cuadernos de Economía  
The paper serves as a first statistical test on whether climatic differences between countries are linked social capital differences.  ...  Moreover, dry elimate and climate of high heights (both extreme elimates) seem to have a similar effect on social capital, as we cannot appreciate a statistically significant difference between them.  ...  The following empírical approach explores the social development index of Temple and Johnson (1998) , inspired by Adelman and Morris and checks whether a statistically significant correspondence with  ...

A statistical inference approach to reconstruct intercellular interactions in cell migration experiments

Elena Agliari, Pablo J. Sáez, Adriano Barra, Matthieu Piel, Pablo Vargas, Michele Castellana
2020 Science Advances  
We propose a statistical inference approach designed to detect the presence of cell-cell interactions that give rise to collective behaviors in cell motility experiments.  ...  Our inference analysis does not provide evidence for interactions, indicating that cells migrate by sensing independently the chemokine source.  ...  Overall, the analysis above indicates that the MEb method, which is based on averages of empirical features only, is able to describe and capture also more complex statistical properties, e.g., the cross  ...

A constructivist approach in a blended e-learning environment for statistics

Stephan Poelmans, Patrick Wessa
2013 Interactive Learning Environments  
The findings ascertain the usability and acceptance of the CP and promote a more radical constructivist approach to the teaching of statistics, but also other subjects.  ...  The deployment of the CP, with interactive workshops and group assignments, immerses students in a novel blended e-learning experience.  ...  We can, for instance, distinguish between a more conventional, objective approach, with a focus on transferring knowledge to students, and a more active, constructivist approach, supporting the learner  ...

A Localized-Statistic-Based Approach for Biomarker Identification of Omics Data

Kuan Zhang, He Chen, Yongtao Li
2013 Engineering  
In order to overcome the problems, we present a computing method called localized statistic of abundance distribution based on Gaussian window (LSADBGW) to test the significance of the feature.  ...  However omics data usually contains a large number of features, but a small number of samples and some omics data have a large range distribution, which make feature selection methods remains difficult  ...  propose a Gaussian window as the local abundance distribution window and a simpler and more general statistic approach to test the significance of the feature.  ...

Investigating selection on viruses: a statistical alignment approach

Saskia de Groot, Thomas Mailund, Gerton Lunter, Jotun Hein
2008 BMC Bioinformatics  
We then integrate this model into a statistical alignment framework, enabling us to estimate selection while explicitly dealing with the uncertainty of individual alignments.  ...  Results: We run a series of simulation studies to gauge how well we do in selection estimation, especially in comparison to the use of a fixed alignment.  ...  More importantly our method is statistical, which means it can be more readily incorporated into a maximum likelihood estimation framework, whereas GenAl works on a count-basis.  ...

Wandering in cities: a statistical physics approach to urban theory [article]

Rémi Louf
2015 arXiv   pre-print
In this thesis we apply some ideas from statistical physics to the study of cities.  ...  Throughout this thesis, we try to convey the idea that the complexity of cities is -- almost paradoxically -- better comprehended through simple approaches.  ...  On the other hand, the traditional approach of Statistical Mechanics is also bound to fail.  ...

Revealing strong correlations in higher order transport statistics: a noncrossing approximation approach [article]

André Erpenbeck, Emanuel Gull, Guy Cohen
2020 arXiv   pre-print
We present a method for calculating the full counting statistics of a nonequilibrium quantum system based on the propagator noncrossing approximation (NCA).  ...  Higher order cumulants are therefore demonstrated to be a proxy for the presence of Kondo correlations in a way that cannot be captured by simple QME methods.  ...  As before, the NCA data is in better agreement with the iQMC results, hinting towards a higher accuracy of the NCA method. For a more detailed analysis, better iQMC data is required. VI.  ...
