QUANTUM ESPRESSO: a modular and open-source software project for quantum simulations of materials

Alfredo Pasquarello, Nicola Marzari, Matteo Cococcioni, Gabriele Sclauzero, Lorenzo Paulatto, Roberto Car

QUANTUM ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave). The ac ...

Coadaptive brain-machine interface via reinforcement learning

Babak Mahmoudi

This paper introduces and demonstrates a novel brain-machine interface (BMI) architecture based on the concepts of reinforcement learning (RL), coadaptation, and shaping. RL allows the BMI control algorithm to learn to complete tasks from interactions with ...

Compiling generics through user-directed type specialization

Martin Odersky, Iulian Dragos

Compilation of polymorphic code through type erasure gives compact code but performance on primitive types is significantly hurt. Full specialization gives good performance, but at the cost of increased code size and compilation time. Instead we propose a ...

A Cross-Cultural User Evaluation of Product Recommender Interfaces

Pearl Pu Faltings, Li Chen

We present a cross-cultural user evaluation of an organization-based product recommender interface, by comparing it with the traditional list view. The results show that it performed significantly better, for all study participants, in improving on their c ...

The Mental Vision framework - A platform for teaching, practicing and researching with computer graphics and virtual reality

Daniel Thalmann, Frédéric Vexo, Achille Peternier

Despite the wide amount of computer graphics frameworks and solutions available, it is still difficult to find a perfect one fitting at the same time many constraints, like pedagogical intents and user-friendliness or speed with high rendering quality and ...

User-Involved Preference Elicitation for Product Search and Recommender Systems

Pearl Pu Faltings, Li Chen

We address user system interaction issues in product search and recommender systems: how to help users select the most preferential item from a large collection of alternatives. As such systems must crucially rely on an accurate and complete model of user ...

A Multimedia Terminal Supporting Adaptation for QoS Control

Marco Mattavelli, Daniele Renzi, Beilu Shao

This paper addresses the End-to-End Quality of Service (QoS) guarantees and control for multimedia content delivery over heterogeneous networks, with a particular focus on end user terminal perspective. We design and implement a multimedia terminal which c ...

Task-based evaluation of meeting browsers: from BET task elicitation to user behavior analysis

Andrei Popescu-Belis

This paper presents recent results of the application of the task-based Browser Evaluation Test (BET) to meeting browsers, that is, interfaces to multimodal databases of meeting recordings. The tasks were defined by browser-neutral BET observers. Two group ...

Survey: Robot Programming by Demonstration

Aude Billard, Sylvain Calinon

Robot PbD started about 30 years ago, growing importantly during the past decade. The rationale for moving from purely preprogrammed robots to very flexible user-based interfaces for training the robot to perform a task is three-fold. First and foremost, P ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
