TL;DR: A scalable analysis tool that can deal with non-parametric statistics on high-dimensional data by combining a MapReduce framework (TomusBLOB) with machine learning algorithms (Scikit-learn library) and demonstrating the scalability and the reliability of the framework in the cloud with a 2 weeks deployment on hundreds of virtual machines.

TL;DR: In this article, the authors applied machine learning on more than 10.000 individuals from the general population to define empirical approximations of health-related psychological measures that do not require human judgment.
Proceedings Article
Mapping cognitive ontologies to and from the brain
TL;DR: This work proposes a method that predicts the experimental paradigms across different studies using a large corpus of imaging studies and a predictive engine, and is the first demonstration of predicting the cognitive content of completely new brain images.
Journal ArticleDOI
Hyperfrontality and hypoconnectivity during refreshing in schizophrenia
Marie-Laure Grillon,Marie-Laure Grillon,Catherine Oppenheim,Gaël Varoquaux,F. Charbonneau,Anne-Dominique Devauchelle,Anne-Dominique Devauchelle,Marie-Odile Krebs,Franck Baylé,Bertrand Thirion,Caroline Huron,Caroline Huron +11 more
TL;DR: The results suggest that prefrontal dysfunctions in schizophrenia might be related to a defective ability to initiate (rather than to execute) specific cognitive processes.
Proceedings ArticleDOI
A Comparison of Metrics and Algorithms for Fiber Clustering
TL;DR: This work proposes an efficient procedure to associate k-means with Point Density Model, a recently proposed metric to analyze geometric structures and analyzes the performance and usability of these algorithms on manually labeled data and a database a 10 subjects.
