Évaluation d’une calculatrice auto-correctrice : Classmate 88

Accélération des cartes auto-organisatrices sur tableau de dissimilarités par séparation et évaluation

Résumé. Dans cet article, nous proposons une nouvelle implémentation d’une adaptation des cartes auto-organisatrices de Kohonen (SOM) aux tableaux de dissimilarités. Cette implémentation s’appuie sur le principe de séparation et évaluation afin de réduire le temps de calcul global de l’algorithme. Une propriété importante de ce nouvel algorithme tient au fait que les résultats produits sont str...

Extending DUNE: The dune-xt modules

We present our effort to extend and complement the core modules of the Distributed and Unified Numerics Environment DUNE (http://dune-project.org) by a well tested and structured collection of utilities and concepts. We describe key elements of our four modules dune-xt-common, dune-xt-grid, dune-xt-la and dune-xt-functions, which aim at further enabling the programming of generic algorithms wit...

ClassMATE: Enabling Ambient Intelligence in the Classroom

Ambient Intelligence (AmI) environments bring significant potential to exploit sophisticated computer technology in everyday life. In particular, the educational domain could be significantly enhanced through AmI, as personalized and adapted learning could be transformed from paper concepts and prototypes to real-life scenarios. In this paper, an integrated framework is presented, named ClassMA...

Classmate Peer Effects: Evidence from Core Courses at Three Colleges*

This paper takes advantage of random assignment of first-year students into core-course sections at three liberal-arts colleges to test for classmate peer effects. Our statistical analysis finds no evidence that more able core-course classmates affect students’ mean academic success outside the core course. While there are several possible explanations for this, interviews with core-course inst...
